I, HENRI BOGAERTS, of Brussels in the Kingdom of Belgium, Directeur de la
Société Anonyme l'Imprimerie Artistique representée par Monsieur le Comte de Mocus
President du Conseil d'Administration, do hereby declare the nature of this invention
to be as follows:-
This invention relates to a peculiar method of preparing drawing paper in order to
reproduce designs made thereon by means of zinc or copper plates so as to imitate
exactly wood engravings.
I am aware that paper has been used on which are impressed straight or oblique
parallel lines without colour but my invention differs essentially from this in the
nature of the lines, their arrangement and combination with other lines, whereby I am
enabled to obtain results that have not been produced before, and which imitate
exactly wood engravings.
For carrying out my invention I employ coated paper on which I impress lines
without colour appropriate to the design which is to be produced, and which
constitute the ground or an important part thereof. I then cover the paper with a
coating of black, filling in all the recessed parts, so that the surface of the paper thus
covered shall be perfectly flush, after which I cover the whole with three or more coats
of white.
On the paper thus prepared I again impress lines without colour, different from
those first produced, for which purpose I prepare in the first instance different lined
grounds engraved on wood.
These impressions being made on paper strongly coated, I then use this as drawing
paper utilising first the lines of the second impression for designing the objects to
which they relate, and removing by means of a scraper those parts not used, so as to
bring out again by this means, as may be required, the lines of the first impression
and using them for designing the parts corresponding thereto. The drawing being
completed I reproduce it upon zinc or copper by means of the zincographic process,
or otherwise, whereupon impressions taken from this have exactly the appearance of
wood ents.

page_text: For certain designs only a single impression without colour may be used; in this
case I print in relief on coated paper the line which I desire to use; this line, which
extends from end to end of the paper is not straight but has the greatest possible
number of curves without having any parts that are either vertical or horizontal; in
addition this line is so engraved or impressed, as in section to produce a series of sharp
angles, thus MMM, which permit of the draughtsman obtaining fine or thick
lines according to the pressure which he exerts on his pencil.
If the paper has two impressions of lines as last above described, running in different
directions, with the interposition of a black coating and several white coatings, the
draughtsman will have at his disposal lines running in all directions which he can make
use of as first above described...
The same system may be used for engraving on wood by means of photography.

page_text: Improved Process and Means for the Reproduction of Designs in
Imitation of Wood Cuts.
I, HENRI BOGAERTS of Brussels in the Kingdom of Belgium, Directeur de la
Société Anonyme l'Imprimerie Artistique representée par Monsieur le Comte de Meeus
President du Conseil d'Administration 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 :-
This invention relates to a peculiar method of preparing drawing paper in order to
reproduce designs made thereon by means of zinc or copper plates so as to imitate
exactly wood engravings.
I am aware that paper has been used on which are impressed straight or oblique
parallel lines without colour but my invention differs essentially from this in tho
nature of the lines, their arrangement and combination with other lines, whereby I am
enabled to obtain results that have not been produced before, and which imitate
exactly wood engravings.
For carrying out my invention I employ coated paper on which 1 impress lines
without colour appropriate to the design which is to be produced and which
constitute the ground or an important part thereof. I then cover the paper with a
coating of black, filling in all the recessed parts, so that the surface of the paper thus
covered shall be perfectly flush, after which I cover the whole with three or more coats
of white.
The material used for producing the black coating may be of indian ink mixed with
gelatine or other suitable glutinous matter; and, the material used for the white coatings
may be ordinary zinc white pigment, but any other black or white pigments having
similar properties may be used.
On the paper thus prepared I again impress lines without colour, different from those
first produced, for which purpose I prepare in the first instance different lined grounds
engraved on wood.
:
These lines may represent foliage as in Fig. 1 of the accompanying drawings wood
as in Fig. 2, sky as in Figs. 3, 4 and 5 or any other subjects which I may consider
suitable for the design to be executed.
These impressions being made on paper strongly coated, I use the paper for
drawing, employing first the lines of the second impression for drawing the objects to
which they relate, removing by a scraper the parts which are not to be used, so as to
make the lines of the first impression reappear as may be required, and to use them
for drawing the parts corresponding to them. Thus, for instance in drawing a
building shewing against sky I first impress on the sheet the almost straight lines
shewn in Fig. 5. I cover this raised surface with black, then with three layers of
white, and I then impress the lines as in Fig. 2. On this last layer I now draw the
building, then I scrape off the coating of the part that is to appear as sky thereby

page_text: making the first impressed lines appear and so I produce the design Fig. 6. For
drawing a landscape with trees and houses for example I should first print the lines
shewn in Fig. 1, then those in Fig. 2 and proceed as above described. Fig. 7 is a
design produced in this manner.
The drawing being completed, I reproduce it on zinc or copper by zincography
or otherwise, and the impression resulting has exactly the character of a wood
engraving.
For certain designs a single impression in relief may serve; in this case I print in
relief on coated paper the line which I desire to use extending from side to side of the
sheet and having the property of not being straight but presenting the greatest
possible number of curvatures without forming straight vertical or horizontal lines;
moreover these lines are impressed in such a way as to form in transverse section a
series of sharp edged angles thus MM, such as allow the draughtsman to obtain
fine or course lines according to the pressure that he puts on the crayon.
If the paper receives two impressions of lines such as I have last described printed
in different directions, with a layer of. black and several layers of white interposed
between them, the draughtsman has at his disposal lines running in all directions
which he can use as set forth in the first part of this description. The design Fig. 8
is thus produced.
The same system can be adopted for engraving on wood by photography.
Having now particularly described and ascertained the nature of this invention
and in what manner
the same
is to be performed I declare that what I
claim is :-
1. The herein described process for preparing paper for the production of imitation
wood cuts which consists in first impressing without color on coated paper lines in any
direction, covering these lines with a layer of black, then with one or more layers of
white, then impressing without color on the last layer lines arranged differently from
the first, for the purpose set forth.
2. For the production of imitation wood cuts, impressing lines upon paper so that
in transverse section they present a series of sharp ridges and furrows substantially as
and for the purposes described.
3. The method of impressing coated paper with raised ground lines of any such
forms as those employed in wood engraving such lines being afterwards utilised in
executing the design to be reproduced substantially as described.
4. The method of producing imitation wood cuts by first preparing a design upon
paper as set forth in the preceding claims, and then reproducing such designs by
zincography or photography, substantially as herein described.
