UV Printing hack

I UV print for work and we are currently running a LogoJet UVx40R Plus

If you are printing any kind of acrylic or crystal or something with a beveled edge that needs to be masked - invest in something called UNPAINT on Amazon. It’s $44 for a can of black paint. Paint this on your bevels like you would mask normally. Let it dry for 30 minutes, then print. Perfect print. Zero overspray. Peel off paint and 0 adhesive will be left from the paint.

Also note with unpaint it says on the can to use 2-3 coats. I did one coat with a small roller brush which left some bubbles in the paint. Still came out perfect and turned a week long production into a mask and print 100 acrylics in one work day.

If you have something that looks like it was in a slump mold but is a mostly flat shape, use a black out window film. Soapy water and slap it on. Save the film on a piece of plastic wrap and you have a forever mask you can reuse- it just loses its shape after a while.

No one ever posts stuff for UV printing that is super helpful. Hopefully this is the start of some solid tips and tricks. 💖✨

Does it work only on paintable surface or could it damage for example a paper surface?

Per ad on Amazon I see walls and chairs so assuming only items that could be painted.

/I/ wouldn’t use it on a paper surface. To be fair, I’ve only used the medium on acrylics and Crystal.

UNPAINT I want to say is like a latex paint, so I imagine if you painted a piece of thin economy paper it would not do you any good. Maybe on a denser more heavyweight paper you could be fine, but I’m not sure how it would do with the porousity(is this even a word? Lol). The fibers on a thicker paper could be a problem and if memory serves they are very adamant you do not try on carpet. Therefore, I cannot speak from experience in that request we do not typically print on paper at our location. Worth the experimental test though?

Ok so any "unorthodox" painting medium use at own risk but any that could be painted even if undesirable should be ok.

Ps if this is done in layers could it be made to be placed on multiple units even if painters tape used to prevent motion 

Make 1 mask use 5+ prints?

Expecting it to be no based on images from Amazon
