AN 1906:53932 CAPLUS DN 0:53932 TI PROCESS FOR REPRODUCING DESIGNS, PICTURES, LETTER-PRESS, AND THE LIKE IN Ostwald, Wilhelm PA Germany SO U.S. CODEN: USXXAM DT Patent LA English FAN.CNT 1 PATENT NO. KIND DATE APPLICATION NO. DATE --------------- ---- -------- -------------------- -------- PI US 798528 A 19050829 US 1903-181403 19031116 AB To all whom it may concern: Be it known that I, WILHELM OSTWALD, doctor of philosophy and professor, a subject of the King of Saxony, residing at Linnestrasse 2/3, Leipsic, Saxony, German Empire, have invented new and useful Improvements in Processes for Reproducing Designs, Pictures, Letter-Press, and the Like, of which the following is a specification. The problem in all reproducing processes consists in applying color to predetermined parts of the receiving-surface while leaving other places free. According as this process is to consist of an alternation between a uniform application of color and a ground remaining unaltered or of a constant gradation of the color from a greatest strength to a zero value in the unaltered ground, line and half-tone processes may be distinguished. In order to form a reproduction, the spacial differences corresponding to the picture must be made to appear upon the receiving-surface. The most simple method of effecting this is by mechanical means-as, for example, in ordinary letter-press printing, where the ink is mechanically applied by means of an even roller upon the projecting faces of the characters from which the reproduction is made. In lithography the different behavior of the fatty design and of the wet ground with respect to fatty ink (which only remains adhering to the fatty design when rolled) serves for producing this spacial arrangement of the ink.
