On Saturday for the first time I printed from a polymer plate on the Vandercook at AS220 (part\u00a02 of my 3-part class on letterpress printing).\u00a0 Students were asked to choose an image (black and white, with no shading), and to send it to a pre-press servicing company which produced the film.\u00a0 Here is the image I sent:<\/p>\n

\"\"<\/a><\/p>\n

And here is the negative which was produced from it:<\/p>\n

\"\"<\/a><\/p>\n

Then we placed the negative on top of a photo-sensitive polymer plate with a layer of backing, exposed it to fluorescent light for about 5 minutes to bake the image in, placed the plate in a warm water bath, lightly scrubbing “away” the film which was in the negative spaces with a flat, soft brush (mine took about fifteen minutes, since it was rather large, about 8 x 8 inches), and then used a hair dryer to\u00a0finish the process.\u00a0 Here is what the plate looks like:\"\"<\/a><\/p>\n

\u00a0Once dry, you peel off a layer from the backing, to reveal an adhesive side.\u00a0 The white stuff you see here was a little bit of paper that got stuck (by mistake) to the backing.\u00a0 The reason for the adhesive is\u00a0so that the plate does not move when you print (these are too flimsy to lock into a chase).<\/p>\n

\u00a0\u00a0\u00a0\"\"<\/a>Using a precision-milled, flat block of steel which is locked into the bed of the press, and guided by a grid printed on its surface, we placed our plates, inked the rollers with a nice smoky red (red mixed with a little black), and ran our prints.\u00a0 Given the level of detail in mine, I think it turned out rather well for a first time effort:<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

For printmakers, the possibilities are greatly multiplied if you have access to this process.\u00a0 This holds true for makers of books as well, of course.\u00a0 In fact, it was this process which made it possible for me to issue a quarterly series while in my previous position.\u00a0 The following cover was produced from polymer plates, which were created by scanning 19th-century type ornaments from specimen books, incorporating them into a computer-generated design, and producing negatives of that design:<\/p>\n
