Lithoing

From Fancyclopedia 1, ca. 1944

Originally, reproduction by stone which absorbed water, and therefore would not take ink, except where it has been marked with a greasy pencil. Metal sheets are now used, which permits reproduction in accurate detail and with large solid areas; fotos can be reproduced in half-tone. The process came into considerable use in fandom with the establishment of Assorted Services, tho publishers presently found commercials who could do the job for them cheaper than Ackerman cud. Costs plenty anyway.
