PROVISIONAL SPECIFICATION.
Improvements in and relating to the Printing of Textile Fabrics.
We, WILLIAM RUMNEY & Co., LIMITED, whose registered office is at 53, Port-
land Street, Manchester, in the County of Lancaster, Calico Printers, and
JAMES YOUNG, of the same place, Foreman Engraver, do hereby declare the
nature of this invention to be as follows:
The object of this invention is to produce shaded or clouded effects on textile
fabrics in an ordinary calico printing machine which we propose to effect by
means of a printing roller or cylinder prepared in a special manner.
In the ordinary rollers employed in calico printing the pattern or design
which has to be reproduced, is sunk or engraved a little below the surface of
the roller.
. The improved rollers which we use, are prepared as follows:-
We take an ordinary engraved copper roller and paint thereon a suitable
design in a varnish for resisting the etching process. This painting may be
effected either by hand or by any other well known mechanical method. The
roller is then placed in an ordinary etching bath. The whole roller is thereby
reduced or etched, excepting the painted or protected parts; the engraved parts
sinking along with the rest of the roller, thus leaving the protected parts
standing up above the surface in relief. The etching is continued until we
consider the painted or varnished portion stands out in relief sufficiently above
the surface of the roller for our purpose.
The roller is now placed in the printing machine and whereever the outstanding
or relief parts of the roller come in contact with the cleaning doctor, the
doctor is prevented from cleaning the surface of the roller itself thoroughly,
and all round these outstanding or relief parts a portion of the colour is allowed
to escape, which when it comes in contact with the fabric produces a shaded
effect such shading tapering from the edges of the relief or outstanding parts,
until the doctor again commences to bear upon the plain parts of the roller.
The shading depends upon the nature of the painted or varnished design and
the depth to which, the etching has been carried.
Or instead of using an engraved roller our improved process may be applied
to a plain roller. Also we may print with one or two or any number of these
rollers at the same time to produce different coloured effects, or. we may also
print with one or more of our improved rollers in combination with one or more
ordinary engraved rollers.
The method of producing the rollers can also be carried out as follows: A
die is cut in the usual way, then we take it and paint thereon the design which
we wish to stand out in relief. The die is now etched in the same manner as
we treated the copper roller herein before mentioned. A mill is raised from
this die and the roller is machine-engraved in the usual manner, the resulting
effect being the same as in rollers previously described.
Dated the 2nd day of August 1899.

We, WILLIAM RUMNEY & Co., LIMITED, whose registered office is at, 53, Port-
land Street, Manchester, in the County of Lancaster, Calico Printers, and
JAMES YOUNG, of the same place, Foreman Engraver, do hereby declare the
nature of this invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement: -
The object of this invention is to produce shaded or clouded effects on textile
fabrics in an ordinary calico printing machine which we propose to effect 'by
means of a printing rollers or cylinder prepared in a special manner..
In the ordinary rollers employed in calico printing the pattern or design
which has to be reproduced, is sunk or engraved a little below the surface of
the roller.
The improved rollers which we use, are prepared as follows:--
We take an ordinary engraved copper roller and paint thereon a suitable.
design in a varnish for resisting the etching process. This painting may be
effected either by hand or by any other well known mechanical method. The
roller is then placed in an ordinary etching bath. The whole roller is thereby
reduced or etched, excepting the painted or protected parts, the engraved parts
sinking along with the rest of the roller, thus leaving the protected parts
standing up above the surface in relief. The etching is continued until we
consider the painted or varnished portion stands out in relief sufficiently above
the surface of the roller for our purpose.
The roller is now placed in the printing machine and whereever the outstanding
or relief parts of the roller come in contact with the cleaning doctor, the
doctor is prevented from cleaning the surface of the roller itself thoroughly.
and all round these outstanding or relief parts a portion of the colour is allowed
to escape, which when it comes in contact with the fabric produces a shaded
effect such shading tapering from the edges of the relief or outstanding parts,
until the doctor again commences to bear upon the plain parts of the roller.
The shading depends upon the nature of the painted or varnished design and
the depth to which the etching has been carried.
Or instead of using an engraved roller our improved process may be applied
to a plain roller. Also we may print with one or two or any number of these
rollers at the same time to produce different coloured effects, or. we may also
print with one or more of our improved rollers in combination with one or more
ordinary engraved rollers.
The method of producing the rollers can also be carried out as follows: A
die is cut in the usual way, then we take it and paint thereon the design which
we wish to stand out in relief. The die is now etched in the same manner as
we treated the copper roller hereinbefore mentioned. A mill is raised from
this die and the roller is machine-engraved in the usual manner, the resulting
effect being the same as in rollers previously described.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that
what we claim is:-
1. Producing shaded or clouded effects on textile fabrics in the manner sub-
stantially as herein before described.
2. The combination with an ordinary calico printing machine of one or more
engraved or other copper rollers having portions forming a design or the like
in relief that are obtained by painting said portions with a varnish suitable

page_text: for resisting the acid in an ordinary etching bath, substantially as and for the
purpose hereinbefore described.
3. The combination with an ordinary calico printing machine of a roller,
that is produced by means of a mill which has been raised, from a die that has
been painted and etched for in the manner and for the purpose substantially
as hereinbefore described.
