Improvements in the Method or Process of Multi-colour Printing,
Part of same being applicable to Mono-colour or Ordinary
Printing.
1, WINFIELD SCOTT ANGLEMAN of 540 West Front Street, Plainfield,
Union County, New Jersey, U.S.A. at present residing at Brown's Hotel, Dover
Street, London Attorney at Law do hereby declare the nature of this invention
(a communication to me from abroad by Thomas William Morrison of Mountain
Avenue, Plainfield, Union County, New Jersey, U.S A.) to be as follows .-
This invention relates to a novel method of process of printing in colonis part
of said process being also applicable to mono-colour or ordinary printing and
pumarily has for its object to 60 ink the form as to produce the desired distribu-
tion blending and varieties of colom upon the sheet or other sui face to be punted
in a single impression or in only a very few unpressions instead of as heretofore
It further includes a
putting each colour or blend separately and successively
novel method or process of preparing or making the ink-receiving jacket or shell
of those rollers of the king mechanism which are proximate to the form inking
oller a special feature of this invention consisting in getting the ink on inks
(either alone or blended) iu patches on the form-inking roller and to other improve-
ments and details all of which are hereinafter set forth.
According to this invention the usual continuous web or other suitable form of
paper (or other suitable material such as cotton textile piece goods) is used as also
the impression cylinder and the type-benting cylinder or form of a printing press
and adjacent to the form is arranged the form-inking roller of any suitable construc-
tion having upon its periphery the customary soft or other suitable inking roller
composition and may be provided with means to adjust the roller so as to compensate
for wear of the composition
Encompassing or partly surround the form-inking roller are sets of inking
mechanisms each set comprising an inking fountain with its customary hard toller
a soft roller or rollers taking the ink from said haid olle and a hard roller
transmitting the ink from the soft rollers to the form-inking roller or other suitable
ink distibuting rollers.
The inking fountain of each said set advantageously consists of a trough mounted
upon studs one of which is connected with an aim adjustably fulcruned and engaging
at its opposite end within a double-grooved eam upon a continuously revolving
inking roller shaft whereby during the revolution of the shaft the said though is
given a reciprocating movement.
This tough is provided with a series of transverse partitions forming pockets
for the reception of inks of different colours One of the purposes of imparting a
reciprocating motion to the tough is to cover with mk those parts of the roller
immediately opposite the partitions It is obvious that the same effect would be
produced by reciprocating the roller itself in any suitable manner either indepen-
dently or in conjunction with the trough. In these pockets of the trough may be
placed tin cases for holding the colours sand cases having openings provided with
To further
suitable means to control or entirely interrupt the outflow therefrom
graduate the amount of colour fell by the hard roller of the inking fountain to the
solt rollers, use 18 made of flexible blades (one for each compartment or tin case)
and by n.cans of a conesponding set suiew iegulate the distance of the free end of

page_text: the blade from the roller and consequently the thickness of the layer of ink supplied
thereto.
Between the form-mking roller and the sets of rollers communicating to the
ink-fountain an inking roller of special form and use to interposed in each of the
different sets of inking devices. The function of each of these said special rollers
is respectively to supply to the form inking rollet the several colours which they
take up from the said sets of rollers.
The main characteristic features of this invention are the method of producing
and utilizing in the general arrangement of the machine the active surfaces of
these said special rollers. For the purpose of making plain their construction
and use I will first explain an advantageous method for producing them.
The matter to be printed on the press having first been composed and justified in
the form a number of proofs thereof are first taken in the usual manner upon
paper of a quality that will withstand without serious injury when suitably
backed the temperature and weight of molten stereotype metal. Tho number
of these proofs should for convemence be one in excess of the primary colours
which it is desired to ultimately print upon the sheet.
18
Upon this extra proof the person whose office it is to determine upon the colouring
indicates by diawing a line about them those portions of the page which are to be
coloured and within or near this line ho also indicates whether they are to be
coloured for instance in red blue and yellow (or other colour or combinations of
colours).
The extra sheet thus marked is together with the unmarked proofs taken to the
proper person who thereupon cuts from one of the unmarked proofs those portions
which are to be coloured red on the printed page. From another of the unmarked
proofs he in like manner cuts those parts that are to be coloured yellow; and so on
If any part of the marked proof is indicated to be printed in a colour blended
from the primary colours as for instance a blend of red and yellow he cute such
part from the proof sheets intended for each of those colours.
The cut proofs thus produced may for convenience be called "maske." They
are each made of the desued thickness and attached to a suitable backing of papier-
mache and each forms the matrix from which a casting in stereotype metal is
produced said casting consisting of a "shell" having in relief then con projections
corresponding in shape and extent to the cut away portions of the mask. These
shells or jackets are cast in semi-cylindrical form so as to be readily applied to the
stock of the said special rollers and the raised portions of these shells constitute
the uking surface thereof thus the shell corresponding to the proposed blue
colouring is placed upon the special toller of the inking set supplying that colour
the shell corresponding to the proposed red colouring is placed upon the special
roller of the inking set supplying that colour and so on.
The and sets of rollers are so arranged with relation to the said special rollers
as only to uk the raised projections and upon operating the piess the several said
special rollers will each supply to the form inking roller patches of colour corres-
ponding in size to the projections thereon and corresponding in distribution to the
distribution of colouring that is to be had upon the form. The several rollers and
the form are of course so geared that the form-inking roller will transmit to the
form itself the colours received in exact register therewith according to the
pre-determined arrangement.
The picture plates employed upon the form for the purpose of illustrating tho
sheet or other surface to bo printed are of any suitable character advantageously
castings in stereotype metal taken from moulds or inatiices produced from swelled
gelatine negatives of the picture itself. In order to produce the proper surface
upon the said special inking rollers to suitably ink these printing plates in accordance
with this invention a second sensitized gelatine plate should be made in a reveran
position to the first negative.
In this manner the second plate will receive a positive impression the reverse
of the impression received by the first plate and when the said reverse gelative

page_text: positive is swelled it will correspond to the first swelled gelatine positive exactly in
outline if the two were placed face to face with the further peculiauty that each
projection upon one of the swelled positives when thus placed face to face would be
in exact juxtaposition to a corresponding projection on the other. It is important
to note that the reverse gelatine positive is not the same as a negative taken from
the original subject for the reason that a negative so takou and swelled if placed
face to face with the swelled positive would present a depression in juxtaposition to
an elevation on the swelled positive and an elevation in juxtaposition to a depression
on said swelled positive. It will be apparent that instead of roversing a sensitized
gelatine plate for the production of the second swelled gelatine positive the same
result could be obtained by placing in the camera a sensitized gelatine plate without
reversing said plate and then employ a reversing lens for obtaining the reverser
negative thereon.
From the swelled reversed gelatine positive produced in other of the ways above
specified (or otherwise) a casting is obtained in stereotype metal m a mould or
matux made from the impression given from the said swelled reversed positive.
The stereotype thus produced is itself a reversed negative of the stereotype first
produced and is placed in the printing form temporarily and an impression is taken
of the entire for in in any suitable manner for instance as usual by pressing upon it
a sheet of moistened papier-mache. This impressed papier-mache serves as the
backing or matix for the masks corresponding to the pictime to be coloured and it
1s evident that the aforesaid stereotype metal inking roller shells cast in such
matrices will have upon their sui faces projections which are reverse negatives of
the picture to be punted or of such portions thereof as are to be printed in particular
colours It will of course be understood that it is within the intent and scope of
this invention to print the picture plates in one colour in which event the reverse
positive projection upon one of the said spacial inking rollers will correspond to
the entire picture When the picture is to be coloured differently in different
parts a portion of said reverse positive will appeal upon another of sand special
inking rollers and so on as heiombefore described
The
In the printing operation the roverse positive stereotype plates that wora
temporarily placed in the printing form are of comse first removed and in their
placo is inserted in each instance the corresponding positive printing plate
character of the reverse positive projections on the said special inking rollers for
inking the picture plates is such that the ink is supplied to the picture plates in
such manner as to produce exceedingly fine effects especially in the shading Thus
each bulging and depression of the picture plate on the form however minute or
considerable finds its counterpart m exact reverse position upon the said special
inking roller or rollers These latter rolleis by reason of their bulgings and
depressious secure the distribution of more ink on their higher portions or bulgings
than on their depressed portions because the higher portions press harder upon the
In like manner
respective fountain rollers from which they take then supply.
these higher o bulging portions of the reverse negatives of the said special inking
rollers give off more ink to the form-tuking roller and at exactly the points where
the negative picture plates of the form present their correspondingly high points
to the form inking roller the more depressed portions receive a correspondingly
less supply. The production of the printing plates themselves and of the
coesponding reverse negatives thereof from like photographic plates and by a
stereotyping process insures absolute uniformity of result and high excellence in
piluct at a cost comparatively small for this kind of work and by the use of
processes or steps which are separately well understood in the art so as to be
capable of being put in practice successfully and readily by workmen whom it
might be difficult to instruct in unfamiliar manipulations.
It is to be observed that the matrix of papici-mache which is to furnish the
backing for the marks corresponding to the ordinary type portions of the form are
to have smooth surfaces thereby producing correspondingly smooth projections upon
the sad special suking rollers these projections buiug of uniform height throughout.
ト

page_text: instead of being regular in height as is the case with the projections corresponding
to the printing plates The advantage of having these uniform projections is that
in practice it is found that the ink is thus distributed to the type to the best
advantage.
It is obvious that for the black colouring for regular type-work the mash would
be cut away at all parts corresponding to the location of the type on the form and
that the stereotype metal shell would have a corresponding projection smooth on
its surface and of uniform beight throughout
The invention may of course be utilised for printing in black only on in que
colour alone for which purpose all the other ink supplying rollers not then
required may be so arranged and mounted as to be independently (or simultaneously)
thrown out of gear or if desired removed bodily out of communication with tho
form inking roller.
LE
In some instances (as for example in hunnedly issuing a late edition or an
23
extra of a newspaper) it may be of importance to save the time requned for
producing the stereotyped picture plate for the form and to use instead thereof a
Hat half-toue or lino engraving. In such case nevertheless it is advantageous to
produce the bulged counterpart upon the said special inking roller or rollers for
the reason that the said bulged counterpart acts as before in distributing the ink to
the form-inking roller. It is however obvious that the same delicacy of shading
can not be obtained by the employment of the flat plate as by the employment of
the stereotyped negative inasmuch as the latter co-operates as has boon herembefore
explained to peculiar advantage in the taking up of the colour from the form-tuking
roller and in exact accordance with the manner in which the said special inking-
roller has imparted said colour to the form-inking 1oller part of this advantago
being lost where a flat engraving is used on the form. In some cases also whole
the bulged reverse negatives are employed upon the inking rollers any design upon
the corresponding surface of the form cylinder may be entnely dispensed with
and instead thereof a smooth surface may be used upon tho form cylinder which
receives the layers of colom of different thicknesses from the form-inking cylinder
and prints them direct upon the paper or other surface to be printed. In this case
the effect produced is somewhat similar to the effect produced by the her embefore
described process
In further explanation of this invention it may be observed that if the form
cylinder alone were provided with the bulged or negular surface for the printing
plates it could not be used to advantage as it would require a laid tympan on the
impression cylinder to produce even fair results inasmuch as a soft tympan would
press to the depressed portions of the bulged surface of the picture plates. In
this invention on the contiary the bulged or regular surfaces of the said special
inking rollers regulate with exactness the thickness of the layers of colour that are
to be applied to the picture plates ou the form whether said pictuo plates be
bulged of flat and it follows necessarily that the picture plates can only print the
uk on the paper in collesponding layers for which reason it is a matter of no
consequence whether the tympan on the impression cylinder is hard as of manilla
paper or soft as of rubber oi felt. For this reason this invention can be applied
directly to existing web presses which paint in one colour and in which soft
tympans such as felt aro invariably used. It will furthermore be observed that in
adapting this invention to such presses the tympan is or may be prepared for the
printing operation in the usual manner employed to ordinary type printing.
Further it will be evident that by the employment of this invention the use of
engravings as commonly understood can be dispensed with for instance such as are
cut by hand or by machine with the aid of engraving tools or that have been
etched by acids or cut by the aid of the sand blast or the like.
In the construction of the king tiough the tin cases hereinbefore mentioned
may be dispensed with and instead thereof the colours may be placed duectly in
the partitioned compartments. But the employment of the cases is advantageous
pincipally because they may be readily tiansferred from one compartment to

page_text: another and because they are or can be made in two parts sliding tele-copically one
within the other whereby the length of then discharge openings may be vaued to
ut the exact requirements of use.
The provision of means for adjusting the supply from the inking fountains play
important parts in the practical utilization of the invention because of the fact
that they permit the supply of colour to be varied from the several fountains with
such graduated regulauity as to produce the exact blend desired where said colours
are superimposed upon each other. So also the dividing of the trough into
sections forming colour pockets in conjunction with the lateral reciprocation of the
trough or its roller and the rotation of the latter not only permits the inking of
those parts of the roller opposite the partitions but permits blendings of colon
upon the rolle itself whereby iainbow and like effects can be readily produced
Instead of forming each mask from a separate proof sheat a single proof may be
laid on a sheet of papier-mache or other suitable material and by puncturing or
Crossing the proof like punctures on crossings will be made in the papier mache
thereby indicating the parts that are to be cut from it.
The papier-mache is then cut along the line of the puncture ou crossings and
thus becomes a mask to be used in the stereotyping operation in the same way that
a cut proof would have been used and for which it furnishes a substitute In this
way a single proof may be used to produce a set of masks for the entire series of
inking rollers each mask being made to correspond with the projection to be
produced upon its appropriate roller.
It may be said generally that in casting the shells by the use of the masks and
then matrices care should he taken to have each mask ut snugly so that the metal
will not run between the mask and the papici-mache matrix or base and to this end
it may sometimes be necessary to touch up or seal the edges of the openings for
instance with clay on some other suitable material.
וון
Any suitable composition may be employed for the form inking voller for
instance the usual composition of glue glycerine and molasses. It inay be cast
upon the segmental bases or shells of the form inking 1oller o 10 10003986
made in said segmental ba-es or in said segmental bases as a fiame work
or in other suntable manner. The impression iolle toim-roller and ink fountain
ollers (the latter hereinbefore referred to Rs sets of rollers) may be of any
suitable construction for instance such as are now Cominon use and need
no further description. Provision should be made by the ordinary adjustments
for regulating the pressure of the various rollers upon each other throughout
the entire press and for varying said pressures at will The rolls when m
the press and not in use should be separated as much as necessary to
prevent the soft rollers becoming flattened by the constant pressure of the hard
rollers on type eylinder upon them this being the usual precaution ordinarily taken
on presses provided with adjacent soft and hard rollers. Also the inking mechanism
is of course so arranged that it may be readily prepared for its work. This
mechanism may for this purpose be swung upon a pivol or drawn upon a side or
rach away from the press or made to re-engage therewith, all for the purpose of
more effectively and perfectly carrying out the method ou process according to this
presont invention, and it may here be remarked that the novel mechanisin oi means
herein described (in connection with the carrying out of this said process) forms
the subject matter of a second and separate application for Patent (u. No. 25114
of 1894) filed concurrently herewith in the same name and beating the same dato
as the present application.
Finally it will be obvious that this process or method may be used in any
character of punting machinery (and fither with flat or curved pinting surface) to
which same is applicable.

Improvements in the Method or Process of Multi-colour Printing,
Part of same being applicable to Mono-colour or Ordinary
Printing.
I, WINFIELD SCOTT ANOLEMAN, of 540 West Front Street, Plainfield, Union
County, New Jersey, US A. at present residing at Brown's Hotel, Dover Street,
London, Attorney at Law, do hereby declare the nature of this invention (a
communication to me from abroad by Thomas William Morison of Mountain
Avenue, Plainfield, Union County, New Jersey, U.S.A) and in what manner tho
same is to be performed to be particularly described and ascertained in and by the
following statement :-
This invention relates to a novel method or process of printing in colours part of
said process heing also applicable to mono-colour or ordinary printing and primarily
has for its object to so mk the form as to produce the desired distribution blending
und varieties of colour upon the sheet or other surface to be printed in a single
impression or in only a very few impressions instead of as heretofore printing cach
colour or blend separately and successively. It further includes a novel method or
process of preparing or making the ink-receiving Jacket or shell of those rollers
of the inking mechanism which are proximate to the form uking roller-a special
feature of this invention consisting in getting the ink or inks (either alone or
blended) in patches on the form-inking 1oller and to other improvements and
details all of which are hereinafter set forth.
According to this invention the usual continuous web on other suitable form of
paper (or other suitable material such as cotton textile piece goods) is used as also
the impress
ession cylinder and the type-beating cylinder or form of a printing press
and adjacent to the form is ranged the form-inking roller of any suitable
construction having upon its periphery the customary soft or other suitable inking
roller composition and may be provided with means to adjust the roller to as to
compensate for wear of the composition.
Encompassing or partly surrounding the form-inking roller are sets of inking
mechanisms each set comprising an inking fountain with its customary hard roller
a soft rolle or rollers taking the ink liom said hard roller and a hard roller
transmitting the ink from the soft rollers to the form-inking rolle 01 other suitable
inh distributing rollers
The inking fountain of each said set advantageously consists of a trough
mounted upon studs one of which is connected with an arm adjustably fulcrumed
and engaging at its opposite end within a double-grooved cam upon a continuously
evolving inking roller shaft whereby during the revolution of the shaft the said
trough 18 given a reciprocating movement.
This trough is provided with a series of transverse partitions formung pockets
for the reception of inks of different coloms. One of the purposes of imparting a
reciprocating motion to the trough is to cover with ink those parts of the roller
immediately opposite the partitious. It is obvious that the same effect would be
produced by reciprocating the rolle itself in any suitable manner either
independently or in conjunction with the trough. In these pockets of the trough
may be placed the cases (for instance tin cases) for holding the colours said cases
hasing openings provided with emitable means to control or entirely interrupt the
outflow therefiom. To further graduate the amount of colour fed by the hard
roller of the inking fountain to the soft rollers, use is made of flexiblo blades (one
for each compartment or tin case) and by means of a coucsponding set sciow
regulate the distance of the free cud of the blade from the roller and consequently
the thickness of the layer of ink supplied thereto
Between the form-king roller and the sets of 1ollers communicating to the ink

page_text: fountain an inking ruller of special form and use is interposed in each of the
different sets of inking devices. The function of each of these sau special roller
is respectively to supply to the form anking roller the several colours which they
take up from the said sets of rollers.
The main characteristic features of this invention are the method of producing
and utilizing in the general arrangement of the machine the active surfaces of
these said special rollers. For the purpose of making plain their construction and
use will fist explain an advantageous method for producing them.
The matter to be printed on the press having first beeu composed and justified in
the lom a number of proofs thereof are first taken in the usual manner upon paper
of a quality that will withstand without serious injury when suitably backed the
temperature and weight of molten stereoty pe metal The number of these proofs
should for convenience be one in excess of the primary coloms which it is desired
to ultunately priut upon the sheet.
Upon this extra proof the person whose office it is to determine upon the
colouring indicates by drawing a line about them those portions of the page which
are to be colored and within or near this hue he also indicates whether they are to
be colored for instance in red blue and yellow (or other colour or combinations of
colours)
The extra sheet thus marked 15 together with the unmarked proof, taken to the
proper person who thereupon cuts from one of the unmarked pioofs those portions
which are to be coloured red on the printed page
From another of the unmarked
proofs he in like manner cuts those parts that are to be coloured yellow, and so on.
If any part of the marked proof is indicated to be printed in a colour blended
from the primary colours as for instance a blend of red and yellow ho cuts such
parts from the proof sheets intended for each of those colours.
The cut proofs thus produced may for convenience be called "masks." They
are each made of the desired thickness and attached to a suitable backing of papier
maché and each forms the matrix from which a casting in stereotype metal is
produced said casting consisting of a "shell" having in relief thereon projections
corresponding in shape and extent to the cut away portious of the mask. These
shells or jackets are cast in semi-cylindrical form so as to be readily applied to the
stork of the said special rollers and the raised portions of these shells constitute
the inking surface thereof thus the shell corresponding to the proposed blue
colouring is placed upon the special roller of the inking set supplying that colom
the shell corresponding to the proposed red colouring 18 placed upon the special
roller of the king set supplying that colour and so on.
The said sets of 1ollers are so arranged with relation to the said special rollers
as only to ink the raised projections and upon operating the press the several said
special rollers will each supply to the form inking roller patches of colour
corresponding in size to the projections thereon and corresponding in distribution
to the distribution of colouring that is to be had upon the form. The several
roller and the form are of course so geared that the foim-inking rollar will transmit
to the form itself the colours received in exact register therewith according to the
pie-determined ari augement.
The pictine plates employed upon the form for the purpose of illustrating the
shect of other surface to be printed are of any suitable character advantageously
castings in stereotype metal taken from moulds or matrices produced fiom swelled
gelatine negatives of the picture itselt la order to produce the proper surface
upon the said special inking rollers to suitably ink these printing plates in
accordance with this invention a second sensitized gelatine plate should be made in
nroverso position to the first negative.
In this manner the second plate will receive a positive impression the reverse of
the impression received by the first plate and when the said Leverse gelatine positive
18 swelled it will correspond to the first swelled gelatine positive exactly in outline
if the two were placed face to face with the further peculiarity that each projection
upon one of the swelled positives when thus placed face to face would be in exact

page_text: juxtaposition to a corresponding projection on the other. It is important to note
that the reverse gelatine positive is not the same as a negative taken from the
original subject for the reason that a negative so taken and swelled if placed faco
to face with the swelled positive would present a depression in juxta-position to au
elevation on the swelled positive and an elevation in juxtaposition to a depression
on said swelled positive It will be apparent that instead of reversing a sensitized
gelatine plate for the production of the second swelled gelatine positive the same
result could be obtained by placing in the camera a sensitized gelatine plate without
reversing said plate and then employ a reversing lens for obtaining the leversed
negative theicon
From the swolled reversed gelatine positive produced in either of the ways above
specified (or otherwise) a casting is obtained in stereotype metal in a mould or
matrix made from the impression given from the sand swelled reversed positive.
The stereotype thus produced itself a reversed negative of the stereotype first
produced and is placed in the printing form temporarily and an impression is taken
of the entne folin u any suitable manner for instance as usual by pressing upon it
a sheet of moistened papier mache This impressed papier mache serves as the
backing or matrix for the masks collesponding to the picture to be coloured and
It is evident that the aforesaid stereotype metal uking roller shells cast in such
matrices will have upon their surfaces projections which are reverse negatives of
the picture to be printed or of such portions thereof as are to be printed in
particular colours It will of course be understood that it is within the intent and
scope of this invention to punt the picture plates in one colour in which event
the reverse positive projection upon one of the said special inking 1ollers will
con respond to the entire picture. When the picture is to be coloured differently
in different parts a portion of said reverse positive will appear upon another of
said special inking rollers and so on as herciubefore described
In the printing operation the reverse positive stereotype plates that were
temporarily placed in the punting form aro of course first removed and in their
place is inserted in each instance the corresponding positive pinting plate The
character of the reverse positive projections on the said special inking tollers for
uking the picture plates is such that the ink is supplied to the picture plates in
such manner as to produce exceedingly hne effects especially in the shading Thus
each bulging and depression of the picture plate on the form however minute or
considerable finds its counterpart in exact reverse position upon the said special
inking 1oller o rollers. These latter rollers by icason of their bulgings and
depressions secure the distribution of more uk on then higher portions of bulgings
than on their depressed portions because the higher portions press haider upon
the respective fountain rollers from which they take their supply. In like manner
these higher oi bulging portious of the reverse negatives of the said special king
ollers give off more ink to the form-uking roller and at exactly the points where
the negative picture plates of the form present then correspondingly high points to
the forin inking 1ollei the more depressed portions receive a correspondingly less
supply. The production of the printing plates themselves and of the corresponding
leverse negatives thereof from like photographic plates and by a stereotyping
process insures absolute uniformity of result anil high excellence in product at a
cost comparatively small for this kind of work and by the use of processes or steps
which are separately well understood in the art so as to be capable of being put in
practico successfully and readily by workmen whom it might be difficult to instruct
in unfamilia manipulations.
It is to be observed that the matrix of papier mache which is to finish the
backing for the masks corresponding to the ordinary type portions of the form ate
to have smooth surfaces thereby producing correspondingly smooth projections upon
the said special inking rollers these projections being of uniform height throughout
instead of being irregular in height as is the case with the projections corresponding
to the punting plates. The advantage of having these uniform projections is that in
practice it is found that the ink is thus distributed to the type to the best advantage.

page_text: It is obvious that for the black colouring for regular type-work the mask would
be cut away at all parts corresponding to the location of the type on the form and
that the stereotype metal shell would have a corresponding projection smooth on its
surface end of uniform height throughout.
The invention may of course be utilised for printing in black only or in one
colour alone-for which purpose all the other ink supplying rollers not then required
may be so arranged and mounted as to be independently (or simultaneously) thrown
out of gear or if desired removed bodily out of communication with the form
inking roller.
"
In some instances (as for example in hriedly issuing a late edition or an "extra
of a newspaper) it may be of importance to save the time required for producing
the stereotyped picture plate for the form and to use instead thereof a flat half-tone
or line engraving. In such case nevertheless it is advantageons to produce the
bulged counterpart upon the said special inking roller on rollers for the reason that
the said bulged connterpart acts as before in distributing the ink to the form-inking
roller It is however obvious that the same delicacy of shading can not be
obtained by the employment of the flat plate as by the employment of the stereo-
typed negative masmuch as the latter co-operates as has becu hereinbefore explained
to peculiar advantage in the taking up of tho colour from the form-inking roller
and in exact accordance with the manner in which the said special inking roller has
imparted said colour to the form-inking roller part of this advantage being lost
where a flat engraving 18 used on the form. In some cases also where the buiged
reverse negatives are employed upon the inking rollers any design upon the
corresponding au face of the form cylinder may be entirely dispensed with and
instead thereof a smooth surface may he used upon the form cylinder which receives
the layers of colour of different thicknesses from the form-inking cylinder and
prints them duect upon the paper or other surface to be printed. In this case the
effect produced is somewhat similar to the effect produced by the herein before
described process.
In
In further explanation of this invention it may be observed that if the form
cylinder alone were provided with the bulged or regular surface for the printing
plates it could not be used to advantage as it would require a hard tympan on the
impression cylinder to produce even fair results masmuch as a soft tynipan would
press into the depressed portions of the bulged surface of the picture plates
this invention on the contrary the bulged or regular surfaces of the said special
inking rollers regulate with exactness the thickness of the layers of colour that are
to be applied to the picture plates on the form whether said picture plates bo bulged
or flat and it follows necessarily that the picture plates can only print the ink on
the paper in corresponding layers for which reason it is a matter of no consequence
whether the tympan on the impression cylinder is hard as of manilla paper or soft as
of rubber or felt. For this reason this invention can be applied duectly to existing
web presses which print in one colour and in which soft tympans such as felt are
invariably used. It will furthermore be observed that in adapting this invention
to such presses the tympan is or may be prepared for the printing operation in the
usual manner employed for ordinary type printing.
Further it will be evident that by the employinent of this invention the use of
engravings as commonly understood can be dispensed with for mstance such as are
cut by hand or by machine with the aid of engraving tools or that have been etched
by acids or cut by the aid of the sand blast or the like.
In the construction of the inking trough the tin cases herein before mentioned
may be dispensed with and instead thereof the colours may be placed directly in
the partitioned compartments. But the employment of the cases is advantageous
principally because they may be readily transferred from one compartment to
Another and because they are or can be made in two parts sliding telescopically one
within the other whereby the length of their discharge openings may be varied to
snit the exact requirements of use.
The provision of means for adjusting the supply from the inking fountains play

page_text: unportart parts in the practical utilization of the invention because of the fact that
they permit the supply of colour to be varied from the several fountains with such
graduated regularity as to produce the exact blend desired where said colours nie
superimposed upon each other. So also the dividing of the trough into sections
forming colom pockets in conjunction with the lateral reciprocation of the trough
o its roller and the rotation of the latter not only permits the inking of those parts
of the rolle opposite the partitions but permits blendings of colour upon the ioller
itself whereby rainbow and like effects can be readily produced.
Instead of forming each mask from a separate proof sheet a single proof may be
laid on a sheet of papier mache or other suitable material and by puncturing of
crossing the proof like punctures on crossings will be made in the papici mache
thereby indicating the parts that are to be out from it.
The papier mache is then cut along the line of the puncture or clossings and
thus becomes a mask to be used in the stereot) ing operation in the same way that
a cut proof would have been used and for which it furnishes & substitute In this
way a single proof may be used to produce a set of masks for the entire series of
inking 1ollers each mask being made to correspond with the projection to be
produced upon its appropriate rolleı.
It may be said generally that in casting the shells by the use of the masks and
their matices care should be taken to have each mask fit suugly so that the metal
will not run between the mask and the papier-mache matux or base and to this end
it may sometimes bo necessary to touch up on seal the edges of the openings for
instauce with clay or some other suitable inaterışl
Any suitable composition may be employed for the forin inking roller for instance
the usual composition of glue glyceriue and molasses. It may be cast upon the
segmental bases on shells of the form inking roller or in recesses made in Faid
segmental bases or in said segmental bases as a frame work o in other suitable
manner. The impression roller form-tollor and ink fountain ollers, (the latter
hereinbefore referred to as sets of rollors) may be of any suitable construction for
instance such as are now in common use and need no further description. Provision
should be made by the ordinary adjustments for regulating the pressure of the
various rollers upon each other throughout the entire press and for varying said
pressures at will. The rolls whieu in the press and not in use should be separated
as much as is necessary to prevent the soft ollers becoming flattened by the
constant pressure of the hard rollers or type cylinder upon them thus being the
usual precaution ordinarily taken ou presses provided with adjacent soft and hand
rollers. Also the inking mechanism is of course so arranged that it may be readily
prepared for its work. This mechanism may for this pu poso be swung upon a
pivot or drawn upon a slide or ach away from the press or made to re-ongage
therewith all for the purpose of more effectively and perfectly carrying out the
method or process according to this present invention, and it may here be remarked
that the novel mechanism or means herein described (in connection with the
carrying out of the said process) forms the subject matter of a second and separate
application for Patent (iz.: No. 25114 of 1894) filed concurrently berewith in the
same name and bearing the same date as the present application and to which
Patent No. 25114 of 1894 reference may be had aud I refer to same as showing
and describing apparatus .e. practical means for carrying out the herein described
method on process.
Finally it will be obvious that this process or method may be used in any
character of punting machinery (aud either with flat or curved printing surface) to 5
which sanie is applicable.
Having bow particularly described and ascertained the nature of this said inven-
tion and in what mauner the same is to be performed I declare that what I
claim 18-
.
1. The method of printing in colours which consists in setting and adjusting type 5
and design blocks in a form taking a proof or proofs of the form prevaring masks

page_text: from said proof or proofs whose cut-away portions correspond to the corresponding
portions of the form that are to be inked in the several colours casting from each
of said masks a stereotype shell having a raised active surface conforming to the
cut-away portion of the mask and mounting each of said shells upon an inking
rolle stock so as to supply to the corresponding put of the punting suface the
several colours intended and punting from said printing surface substantially as
described
2. The method of printing a design which consists in producing the same upon
an inking sm face m patches of uk of varying thickness corresponding to the tones
and shadings to be printed the thickest portions of said patches being upon the
highest projections of the inking surface and the thinner portions being upon the
lower depressions thereof transferring suid ink design as thus received by the inking
surface to the punting sin face and pinting from the puntang surface substantially
as described.
3. The method of printing a design which consists in producing the same upon
an inking surface in patches of ink of varying thickness corresponding to the tones
and shadings to be printed inking the printing surface from said inking surface and
pinting from the punting surface said printing surface bearing the negative
configuration of the desigu to be printed substantially as described.
4 The method of printing a design which consists in producing the same upon
an inking surface in patches of ink of varying thickness corresponding to the tones
and shadings to be printed inking the punting surface from said inking surface and
printing from the printing surface said printing surface bearing the bulged or
swelled negative configuration of the design to be printed substantially as described.
5. The method of inking a printing surface with patches of uk of varying
thickness corresponding to the tones or shadings of a design to be painted which
consists in casting a facsimile of a swelled negative of the design inking said
facsimile transfeiring said ink to an inking Eu face and then transferring it to the
printing surface substantially as described
6 The method of inking a punting surface with patches of ink of varying
thickness corresponding to the tones or shadings of a design to be printed which
consists in casting a facsumile of a swelled negative of the design inking said
facsimile transferring said ink to au inking sui face and then transfering it to the
printing surface said printing surface beating a east facsimile of the swelled negativo
substantially as described.
7. The method of punting a design in colours which consists in preparing cast
facsimiles of frictional portions of a swelled negative of the design inking said
facsimiles in various colours transfeiring said colours to an inking surface transferring
them therefrom to the printing surface and finally printing from the latter
substantially as described.
8. The method of producing the shell of an unking roller which consists in taking
a proof from the printing form preparing a mask from said proof superimposing the
mask upon a matrix and thereupon casting upon said matrix substantially as
described.
9. The herein described improved method or process of printing substantially in
the mauner aud for the purposes set forth
