page_text: GEORGE CORPE WHITFIELD Ealing The Woodbury Castlebar Ealing do hereby
declare the nature of this invention to be as follows:-
My invention relates to the production of Woodbury Type prints with clean margins,
suitable for binding in books and to avoid the necessity of mounting as has hitherto
been the practice.
In order to carry out my invention I either by marking the relief during printing
or by trimming it afterwards produce a mould which will on printing give a clean
white line or edge surrounding the picture. Some of the ink squeezed out in the
process of printing will remain on the paper beyond the white edge aforesaid this is
afterwards removed by washing or wiping away up to the white edge leaving the
paper clean.

page_text: I GEORGE CORPE WHITFIELD, The Woodbury, Ealing 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 relates to the production of prints by the well known Woodbury
type process; and it has for its object to enable such prints to be directly produced
with a broad, clean, white margin suitable and ready for binding into books and
having all the appearance of prints which have been trimmed and mounted in the usual
way heretofore practised.
In carrying out my invention, I may either mask the margin of the gelatine relief
during the printing thereof from the negative, so as to sharply limit the outline of the
area printed, or I may trim the finished relief to the intended size and shape of the
picture.
I, however, prefer the first mode as by that means the marginal portion of the
collodion support of the gelatine relief from which the gelatine has been wholly washed
off remains as a margin around the relief and by its thickness interposed between the bed
of the press and the plate of lead of which the matrix or mould is to be formed, reduces
the extent to which the marginal portion of the lead plate will stand up above the
level of the matrix proper from which the picture is to be printed.
From a relief treated in either of the above mentioned ways, a matrix is produced
by subjecting a plate of lead to pressure when in contact with the relief, in the ordinary
and well known way, the lead plate being however, of so much larger dimensions than
the picture, that a plain (and preferably broad) marginal surface will be formed at all
four sides of the subject or intaglio portion of the matrix. This marginal surface being
plain and standing up above the general level of the subject or intaglio portion, pro-
duces in printing a picture having a sharply defined edge, but some of the ink squeezed
out in the process of printing will remain on the marginal portion of the
the paper, and
this superfluous ink is to be afterwards removed by washing away up to the edge of
the picture with a cloth moistened with hot water, leaving the edges of the picture
sharply defined and the margin quite clean.
The paper generally used for Woodbury type prints is unsuitable for binding into
books, as it is too light of substance and in consequence of the treatment it undergoes
in the course of the Woodbury type process, it is liable to tear out very easily from
the binding. It is necessary to use a paper of an even texture, sufficiently stout and
tenacious to withstand the effect of the process and be held by the binding without
liability to tear easily, and hard enough to receive on its surface without absorbing,
the waterproofing preparation necessary for the Woodbury type printing and for the
removal of the superfluous ink from the margin by washing as above mentioned. I
find paper of the kind and quality known as Cream Wove tub sized drawing paper
70 lb. Imp." to be a suitable paper for the purpose, but I do not restrict myself to the
employment of that paper alone.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The production substantially in the manner herein described, of Woodbury type
prints with sharply defined edges and clean margins, such prints having the appear-
Ince of mounted prints and being suitable for binding in a book without undergoing
The operations of trimming and mounting.
