This came up in my current build. It's my second time doing self-printed inkjet waterslides, but the first time using white-backed (rather than clear.) So I printed and clear-coated the sheet, then cut out the first one and went to apply it... and the ink started to run. It was mostly at the edges, but to be completely honest, I didn't get a good analysis before I pulled it off and chucked it. These decals are all cut out right through the ink at the edges, else there would be unwanted white borders. In this case, is it necessary to seal the edges of the decals? If so, what is the best way to do it? My theory is that water was getting in a bit at the edges; that seems logical, but I don't recall anyone discussing this issue before. I've now cut out all the decals in preparation for sealing the edges, and then realized I'm not sure what's the best way to do it. Just double-stick tape them all down to a sheet and give another good clear coat? I'm kinda making it up as I go here. Anyone dealt with this before?
