G R A P H I C S - P R O. C O M 2 0 2 0 J U L Y G R A P H I C S P R O 2 9 we were in full COVID-19 mode, mak- ing getting help a bit more difficult. But we managed. As I began working on the slabs, several of our suppliers had shut down, and we were not sure which materials we would be able to get, so I decided to go with what we had and could process ourselves. We cut the names into our 11-mil soft vinyl resist and applied the stencils to the panels. Yes, we did have to weed them, but at least it was reliable material that we had in-house. We tried cutting the logo in the vinyl and it turned out well, but some of the lines were so thin that I was afraid they would shift during the blasting, and I did not want to make them thicker. So, I opted to make the logo out of our 5-mil photoresist, which turned out nicely. I cut an opening into the stencil at the top of the middle panel and inserted the photoresist, then taped off the cut lines. I was finally ready to blast. BLAST AWAY We wheeled the panel into the blast room and set it up on cinder blocks so I would not have to crawl on the floor to reach the bottom names. I blasted the names with silicon carbide at about 60 pounds of pressure. The blasting itself took about an hour and a half at a steady pace. Blasting that many names on one piece is always a challenge since you can only rely on your eyesight to hopefully achieve Center panel partially blasted.
