Picasso is often credited with inventing the reduction printing technique. From 1958-1963 he created approximately 100 reduction linocuts. I haven’t been able to find much information online about the history of this technique, but from what I’ve found it seems to have been in use by small commercial printers and taught in art schools for some time before Picasso brought it to wider attention. He was probably introduced to the technique by a commercial printer, and adopted it due to his frustration with the slowness and discontinuity of having to cut each color area on a separate block.
Today I printed the fifth color on all the prints. Tomorrow will be my last day in New Mexico, so be sure to tune in to see the finished prints. For now, here are all five stages so far of the Silver-spangled Hamburg.
