As part of a custom order of Ingress badges, I recently had a chance to revisit kiss cutting. I’d played with the process a few times before but not on 52lasers projects.
Kiss Cutting is one of the most popular methods for creating pressure-sensitive labels. During the kiss-cutting process, the perimeter of each label is cut by a sharp metal die or laser beam…but the cut does not penetrate the label’s backing material (liner). – Formax Printing
In this run, the client and I opted to use thin self-adhesive acrylic stickers to allow for adjustable agent levels, saving on badge reprints when agent levels change. Each badge was to receive its own accompanying sticker sheet with options for sixteen levels. Because it’d be just plain silly to have that many separate stickers to keep track of, using a kiss cut to carve stickers out on a rectangular sheet made a lot of sense.
With our 40w laser, I cut the sheets out of the LaserLights material at full power and 80% speed. The octagonal stickers themselves were kiss-cut at 35% power at full speed. It took a little nudging of the numbers to end up at that point; earlier kiss cutting attempts weren’t cutting all the way through the adhesive transfer paper but they were still scoring it enough to make removing stickers tricky.
While the stickers turned out great and will perform their function admirably, the aesthetic clash between silver foil/black stickers on fluorescent transparent green acrylic is stronger than we’d like, so future runs are likely to utilize a different adjustable level solution.
