"He who marches out of step hears another drum." ~ Ken Kesey
I could see these used in a sticky lint pickup screen, eliminating the need to keep the screen "lubricated"
...I often hear of folks using a screen directly after the flash, while the ink is still hot, to "mat" the ink down. I would imagine this would work, but let's take that a step further. Imagine the different special effect possible if there were patterns embossed, or debossed, into that cylinder? FUUUUUUUNN!!!
