PROVISIONAL SPECIFICATION.
Improvements in or relating to Calico Printing.
I, LEON LANG of 16 Peel Terrace, Old Trafford, Manchester, Designer, do
hereby declare the nature of my said invention to be as follows :--
These improvements have for their object to enable various colored designs to be
printed on calico or other similar textile material with a less number of engraved
rollers than heretofore, but with the same or a botter effect, and consists in the
employment of an ordinary calico printing roller on which is engraved the ground
work of the subject to be printed, the shades and shadows being likewise produced
on said roller by stippling or line engraving and thus forming a complete design in
itself which can be printed as a single color pattern.
This engraved roller serves to print the outline of the subject, and also the
ground shades and shadows of the subject at one impression, leaving the various
colors and tints which it is desired to give the subject, to be applied by a separate
roller for each color. When said colors are applied they have the same tone as that
produced by tints repeatedly applied one above another by a number of rollers in
order to give greater or less prominence to certain portions of the design as
heretofore to produce shade or shadows.
These improvements are applicable to block printing.
Dated this 28th day of January 1893.

COMPLETE SPECIFICATION.
Improvements in or relating to Calico Printing.
I, LEON LANG of 16 Peol Terrace, Old Trafford, Manchester, Designer, do
hereby declare the nature of my said invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:-
These improvements have for their object to enable various colored designs or
patterns to be printed on calico or other similar textile material with a less number
of engraved rollers than heretofore and with the same or a better effect, and
consists in the employment of an ordinary calico priuting roller on which is
engraved the whole of the outline or ground work of the subject to be printed, the
shades and shadows being also produced on said roller by stippling or lino
engraving, and thus forming the complete design on a single roller, which can be
printed as a single color pattern.
This engraved roller serves to print the outline of the subject, and also the
ground shades and shadows of the subject at one impression, leaving the various
colors and tints which it is desired to give the subject to be supplied by a separate
roller for each color. These color rollers are only engraved to an extent sufficient
to receive the color and impart it to the fabric. When said colors are applied they
have the same tone as that produced by tints repeatedly applied one above another
by a number of separately engraved rollers in order to give greater or lesser
prominence to certain portions of the design to produce shades or shadows..
In producing a colored design or pattern by my invention it is necessary that
the ground tints should be neutral that is the color of the outline as imparted
by the roller aforesaid and the first color afterwards applied should match, for
FD-031

page_text: example a black outline and a slate color to follow or a brown outline and a
chocolate color to follow.
The application of the two neutral colors by themselves produce a complete one
tinted design and in applying additional colors the said neutral colors give the
subject of the design a very natural effect.
Having thus particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that. what I
claim is :-
1st. Printing colored designs or patterns on calico or the like by means of a
roller bearing the entire engraving of such designs or patterns and afterwards
applying the various colors by separate color rollers substantially as hereinbefore
described.
2nd. In printing colored dosigns or patterns on calico or the like as described in
the previous claim the use of neutral colors as and for the purposes hereinbefore
described.
