The slight shifting of each print or printed sheets with respect to each other, in transferring their impressions one above the other to the stone or plate results in the production of unexcelled marble pa er effects.
t is to be understood that,while I prefer to use different colored inks in making the prints or printed sheets, the invention may be practiced by printing with the same colored ink upon the prints or printed sheets, the slight shifting of the sheets, which constitutes the essential features of my inven tion, being done as hereinbefore described. Where the stone or late has applied thereto only ink of one co or, it is reinked in the usual way. When however, inks of different colors are applied thereto, as hereinbefore described, the reinking. is accomplished in the'same manner as that in which the first ink is apkplied. This has been hereinbefore' set fort It is to be understood that the original negative may be reproduced in diiierent colors upon the separate prints or sheets by'any known methods and that in the production of the stone or plate to be used in the knives or other means may be employed to eflect corrections in the stone or p ate where the color is too heavy 'or the lines too close together and that weak spots or arts showing linestoo far apart may be lled in with color bv of a gelatin plate or screen, in accor ance with the present 'ractice in the art.
Having thus descri ed my invention, 1 claim:
1. The herein described process which con l sists' in photographing a design through a grain 1 plate, reproducing said design upon separate [prints or sheets, transferring the diflerent impressions of the said prints or sheets to a stone or plate, one impression being superimposed upon another, but each impression being shifted somewhat from exact coincidence with adjacent impressions, and finally printing from said stone or plate.
2. The herein described process which con- I sists in photographing a design through a grain plate, producing an autotype from the negative thus made, producing separate impressions in different colors from said autotype, superimposing said impressions one above the other, but somewhat out of exact coincidence, upon a lithograph stone or analogous plate and finally printing from said stone or plate.
In testimony whereof I presence of two witnesses.
