COMPLETE SPECIFICATION filed by the said Ludwig Hermann Philippi at
the Office of the Commissioners of Patents on the 26th June 1883.
LUDWIG HERMANN PHILIPPI of Hamburg Germany " IMPROVEMENTS IN
PRINTING CLOTH OR WALL PAPERS, WHICH INVENTION IS ALSO APPLICABLE,
FOR PRINTING OR EMBOSSING WOVEN FABRICS OR OTHER MATERIALS OR
SUBSTANCES
"
This invention relates to improvements in printing cloth and wall papers and
the object of my improvements is the application of photo-engravings or photo-
relievos to this purpose.
To effect this a photograph of any object is used for making therefrom a photo-
engraving or photo-relievo advantageously by means of a plate made (according to
the process described in my English Patent N° 4562 of 1882) of a non-corrosive
base covered by the couch or layer to bo etched whereby the depth of the
excavations produced by etching the upper layer down to the non-corrosive baso
may be previously fixed. The photo-relievos or photo-engravings thus produced
which are or are to be curved according to the size of the printing-cylinder or
from the original photo-relievo or photo-engravings clichés may be taken by means
of galvano-plastic or otherwise which are bent in the above mentioned manner.
If the design which is to be executed by print contains various colors evidently
each of these colours requires a corresponding cliché, such different clichés are
obtained in the following manner: the original negative picture on glass is used
for taking a number of equally sized glass-copies in which are removed by
retouching or covered by colour all those parts of the design which ought not to
appear in the photo-engraving or photo-relievo; or these parts may be cut out
mechanically from the photo-relievos or photo-engraving.

page_text: The printing-cylinder for printing cloth or wall paper such as is employed in
ordinary printing machines, is formed or covered either entirely or partly by a
number of such curved plates, also the metal plates cast (according to the process
described in my English Patent N° 124 of 1882) in moulds made by means of
photo-engravings or photo-relievos may advantageously be employed.
Having thus described the nature of my invention I would have it understood
that what I claim is :-
First The application of photo-relievos or photo-engravings for printing or
embossing cloth, wall paper, woven fabrics or other material or substance
substantially as described.
"
•
Second The application of printing cylinders either partly or entirely made of
or covered by photo-engravings or photo-relievos or by clichés taken therefrom for
printing cloth or wall paper substantially as set forth,
In witness whereof I the said Ludwig Hermann Philippi have hereunto set my
hand and seal this Twelfth day of June in the year of our Lord One thousand
eight hundred and eighty three.
LUDWIG HERMANN PHILIPPI. (L.S.)
