PROVISIONAL SPECIFICATION.
Improvements in or relating to Lithographic Transfer Paper.
I, CHARLES HENRY VEALE, of 124, St. Patrick Street, Cork, Ireland. Foreman
Lithographer, do hereby declare the nature of this invention to be as follows: -
The object of my invention is to provide a new or improved composition or
coating for paper to be used for lithographic transfer purposes, whereby any
lithographic printer, by an uniform method of treatment. will be enabled to
successfully deal with all classes of "moist transfer work" by one paper adaptable
to the three purposes for which such paper is required, i.:-Plate to stone:
stone to stone (including crayon or grained work); and type to stone: instead
of using a special paper for each process, requiring different experience and treat-
ment.
聾
According to my invention, in operating upon (for example) an average of
two reams of demy paper measuring 221 inches by 17 inches, with eight to nine
pounds of coating per ream when dry, I apply the following ingredients in forming
the coating:
1st. 6 pounds of pastry flour boiled in 24 pints of water, into which, when
boiled. half a noggin of nurified carbolic acid is mixed.
2ndly. 16 pounds of French mordant white and half an ounce of vermillion,
mixed in one pint and a half of No. 2 pure glycerine.
3rdly. Refined plaster of Paris beaten up in eight pints of water and allowed to
stand overnight; after pouring off the surplus water standing on the surface, add
six ounces of Russian glue and raise all to a boiling heat.
The whole of these ingredients (excent the flour) are then to be mixed and well
ground. The boiled flour is then added, well mixed and strained. The material
is then ready for coating the paner.
The transfer paper prepared according to my invention does not harden or
deteriorate by age, and imparts to the work in operation the qualities of added and
permanent strength, together with the impossibility of a "spread" or imperfect
results and the concentration in one system of treatment for all moist transfers
simplifies the whole process, and gives confidence to the workmen by its uniform
success.

According to my invention, in operating upon (for example) an average of
2 reams of demy paper measuring 22 inches by 17 inches, with 8 to 9 pounds of
coating per ream when dry I apply the following ingredients in forming the
coating:-
1st 6½ pounds of pastry flour, boiled in 24 pints of water, into which, when
boiled, half a noggin of purified carbolic acid is mixed.
2ndly 16 pounds of French mordant white and half an ounce of vermillion,
mixed in 1 pint and a half of No. 2 pure glycerine.
3rdly Refined plaster of Paris beaten up in 8 pints of water and allowed to
stand overnight; after pouring off the surplus water standing on the surface, add
6 ounces of Russian glue, and raise all to a boiling heat.
The whole of these ingredients (except the flour) are then to be mixed and well
ground. The boiled flour is then added, well mixed and strained. The material
is then ready for coating the paper.

The transfer paper prepared according to my invention does not harden or
deteriorate by age, and imparts to the work in operation the qualities of added
and permanent strength, together with the impossibility of a spread or im-
perfect results, and the concentration in one system of treatment for all moist
transfers, simplifies the whole process, and gives confidence to the workmen by its
uniform success.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:
-
1. A new or improved composition or coating for lithographic transfer paper
consisting of pastry flour boiled in water to which purified carbolic acid is added
and mixed, French mordant white and vermillion mixed in glycerine, refined
plaster of Paris treated with water as described; and Russian glue, the ingredients
being prepared and mixed in or about the proportions specified, substantially as
set forth.
2. The method of preparing a composition or coating to be applied to paper to
be used for lithographic transfer purposes substantially as and for the triple pur-
poses herein before described.
