Invention of "IMPROVEMENTS IN THE PRODUCTION OF SURFACES FOR
PRINTING, STAMPING, OR EMBOSSING."
PROVISIONAL SPECIFICATION left by the said Joseph Julius Sachs at
the Office of the Commissioners of Patents on the 19th July 1880.
JOSEPH JULIUS SACHS, of the City of Manchester. "IMPROVEMENTS IN THE
PRODUCTION OF SURFACES FOR PRINTING, STAMPING, OR EMBOSSING."
My Invention relates to an improved method of producing roller surfaces for
printing, stamping, or embossing, whereby the ordinary process of engraving is
dispensed with.
:
In carrying out my Invention I take a piece of lace or other open work fabric
or material, and arrange the same around a roller; and I place the roller (having
the lace or other open work fabric or material thereon) in a bath containing a
metallic solution connected with an electric current, and by preference cause the
roller to revolve therein.
The lace or other open work fabric or material serves as a resist whilst the
metal is deposited on its interstices. The lace or other fabric or material is then
removed, and the roller is ready for printing, stamping, or embossing with in the
ordinary manner.
I also produce casts of open work fabric, material, or design, in relief or sunk,
placed upon a roller with any suitable substance, such, for example, as plaster of
Paris, and cover such casts with metal by means of an electric current or otherwise.
I then remove the material with which the cast has been made by any suitable
means, as, for example, in the case of plaster of Paris, by boiling in a solution of
hydrochloric acid and water. I then fill the inside of the remaining hollow metallic
surface with any suitable metal or compound, either by means of electricity or in
a molten state, or otherwise, and thus produce a roller whose surface contains or
bears the facsimile of the open work fabric, material, or reliefed or sunk design,
and which may then be used for printing, embossing, and other purposes.

page_text: I also produce a facsimile of open work fabric, material, or design, by the action
of light in any suitable manner on a roller covered either with chrome-gellatine or
asphaltum, or any other substance or material, producing a similar effect. I next
remove the material which has not been acted upon by light by any suitable
means, as, for example, in the case of chromo gelatine by water, and I then deposit
metal on the parts of the roller from which the said substance has been removed
by means of a galvanic or electric current or otherwise.
Or I produce a facsimile or photograph of open work material, fabric, or design
by the action of light on a close material, such, for example, as paper and the like
covered with a layer of chrome gelatine or asphaltum, or any other suitable material,
and attach the facsimile thus produced to a roller with the layer side next thereto
by any suitable means under application of pressure. I next remove the material
or paper by washing, and then either etch or deposit metal on the facsimile thus
transferred to the surface of the roller.

JOSEPH JULIUS SACKS, of the City of Manchester. " IMPROVEMENTS IN THE
PRODUCTION OF SURFACES FOR PRINTING, STAMPING, OR EMBOSSING."
My said Invention relates to improved methods of producing roller surfaces for
printing, stamping, or embossing, whereby the ordinary process of engraving is
dispensed with.
.
In carrying out my said Invention I take a piece of lace or other open work
fabric or material, and arrange the same around a roller by.forming a cylinder or
hose of the open or closed fabric, say, for example, by sewing or forming together
its two ends, directly or indirectly (with a piece of another material between the
ends), and slipping it over the roller in its proper place. I then introduce the roller
with the fabric or material thereon into a solution of caustic soda containing about ten
to twenty per cents. of Na OH until the fabric or material is sufficiently contracted,
after which I place the roller with the fabric or material thereon in a bath containing
a metallic solution connected with an electric current, and by preference cause the
roller to revolve thereon. The lace or other open work fabric or material serves
as a resist whilst the metal is deposited through its interstices on the surface of the
roller. The lace or other fabric or material is then removed, and the roller is ready
for printing, stamping, or embossing with in the ordinary manner.
I also produce with any suitable substance, such, for example, as plaster of Paris,
gutta percha, and the like, casts of open work fabric or material, or of sunk or
raised designs placed upon a roller or inside a hollow cylinder. After the cast has
set I remove the roller or cylinder with the open work fabric or material thereon,
and cover such casts with metal by means of an electric current or otherwise. Í
then remove the material with which the cast has been made, as for example, by
boiling in water containing, in the case of plaster of Paris having been used,
hydrochloric acid. I then fill the inside of the remaining hollow metallic surface
with any suitable metal or compound either by means of electricity or in a molten
state or otherwise, and thus produce a roller whose surface contains or bears the
fac simile of the open work fabric material, or relieved or sunk design, and which
may then be used for printing, stamping, or embossing.
..
I produce a facsimile of open work material or fabric, or of photographs or other
designs, by the action of light on a close material, such, for example, as paper and
the like covered with a layer of chrome-gelatine, chrome-gum, chrome-saccharine,
or their equivalents, or with asphaltum either used alone or mixed with any suitable
material, such, for example, as resin and the like. I attach the facsimile thus
produced to a roller with the layer-side next thereto by suitable means under
application of pressure. I next remove the paper or material by washing, leaving
the layer upon the surface, wash off the parts of the layer upon which the light.
had not acted, and etch or deposit metal on the facsimile thus produced on the
roller.
Having now described and particularly ascertained the nature of my said
Invention, and the manner in which the same is or may be used or carried into
effect, I would observe in conclusion that what I consider to be novel and original,
and therefore claim as the Invention secured to me by the hereinbefore in part
recited Letters Patent is,-
First. The system or mode of obtaining roller surfaces for printing, stamping, or
embossing by depositing metal on a roller through the interstices of lace or other
open work fabric or material, substantially as herein before described.

page_text: Secondly. The system or mode of obtaining roller surfaces for printing, stamping,
or embossing from casts of open work fabric or material, or of designs in relief and
sunk, substantially in the manner hereinbefore described.
Thirdly. The system or mode of obtaining roller surfaces for printing, stamping,
'or embossing from fac similes produced' by the action of light of open work, fabrics,
material, or of photographs or other designs, substantially in the manner herein before
described.
. In witness whereof, I; the said Joseph Julius Sachs, have to this my
Specification set my. hand and seal, this Sixth day of January, One
thousand eight hundred and eighty one.
