I THOMAS D. WORRALL, a Physician, of Lynn, Massachussetts in the United States
of America & now temporarily residing at No. 37 Pyrland Road, Highbury New
Park, London N. England do hereby declare the nature of this invention to be as
follows:-
An improved method of printing in colors, by means of prepared paper, silk, or
other fabric, which has been saturated in different colored pigments or inks then dried,
or partially dried & interposed between printing type, or cuts & the paper to be
printed & then passed through a printing press, by which process printing can be done
in two, or more colors at one impression, or by first rolling the face of the type with
ink, in the usual manner of printing & then placing thereon strips of paper, or other
fabric, saturated in different colored pigments, so as to print in two, or more colors
at one & the same impression.

page_text: 1, THOMAS DAVID WORRALL, a Physician, of Lynn Massachussetts, U.S.A., and
now temporarily residing at 26 Red Lion Square, Holborn, in the County of
Middlesex, 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:-
My invention consists in an improved method of printing in colors by means of
prepared paper, silk or other fabric which has been saturated in different colored
pigments or inks then dried, or partially dried, and interposed between printing type,
or cuts, and the paper to be printed and then passed through a printing press, by
which process printing can be done in two or more colors at one impression; or by
first rolling the face of the type with ink, in the usual manner of printing, and then
placing thereon strips of paper, or other fabric, saturated in different colored pigments,
so as to print in two or more colors at one and the same impression.
In carrying out my invention, and performing the same, I first take any desired
and suitable pigments, such as analine, or the like, of any required color, and dissolve
them in a suitable solvent such as water, alcohol, Glycerine, oil or any desired mixture
of either, or any of these and so prepared that the colors thus dissolved will not too
readily set or dry, but will remain somewhat moist and casily available for use by
pressure. I then take sheets or rolls, or strips of tissue or other paper, silk or other
similar suitable fabric, or material, and soak them in, or otherwise saturate them with,
the pigment so prepared as above mentioned. The pigment of any color may thus be'
applied to the paper or material in strips or spots, or according to any desired design:
or different parts of one sheet or strip may be saturated with different colors. The
paper or other material will then be dried, or partially dried, to enable it to be
conveniently handled, and to insure a clear impression from the color when printing.
The pigments may be applied by means of ordinary printing rollers, such as are
used in calico printing; or the paper may be impregnated by means of pencils, or
brushes, such as are used in preparing ruled paper. As an alternative method; instead
of a single sheet saturated with more than one color, I can take tissue paper, or other
similar and suitable material, and first saturate or impregnate it with one color, using
it as a base; and then lay over or secure to it strips shapes or designs of other paper
silk or the like each saturated and containing different colors; the whole being then
dried as far as necessary, and the many colored sheets may be made of pieces con-
nected at their edges, either before or after saturating with pigments and then dried.
In carrying out and performing my method or process of printing in colours, I take
one or more of the colored sheets or strips or shapes prepared in any of the ways above
described and place it or them upon and over the face of the type, electro, stereo,
woodcut or plate to be printed from. I then lay the paper to be printed upon over this,
and so pass the whole under the cylinder a platin of a printing press, in the
ordinary manner. In this way I am enabled to print in two or more colors and

page_text: according to any shape or design by one impression and without the use of the
usual printers ink. I can also combine my process with the use of such ink by first
rolling the types with ink of any color so as to form a base color, and then laying
my saturated colored strips or shapes upon this, and putting the paper to be printed
upon over all. By either method I can print any desired number of colours in
strips or designs by a single impression.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is,
1. The use of paper silk or similar suitable fabrics or materials, saturated or
prepared with pigments for the purposes of colour printing, as above described.
2. The process of printing in two or more colours by one impression with such
saturated or prepared papers or other materials, interposed between the type and the
paper, and either alone or combined with printer's ink as above particularly
described.
