I am playing around with different ways to seal the ink on printable shrink plastic. My last attempt resulted in very "bleedy" ink and an undesirable effect overall, as seen in this blog post.
My next adventure in shrink plastic sealing begins with doing what I should have done in the first place: read and follow directions.

I took a handful of inkjet Shrinky Dinks and sprayed them with Krylon Crystal Clear Acrylic coating. This is how I did it:
1. I followed the directions on the can: shake for 2 minutes, hold about 12 inches away, spray with a quick sweep. It was probably hotter outside than the maximum recommended temperature, but I did store the Krylon inside.
2. Let it dry for 15 minutes.
Here are the results:


After one coat, it was very difficult to see any kind of sheen, much less a "gloss." So after 15 minutes, I resprayed...

After the second coat dried, a sheen was visible, although I would still not call it a "glossy" effect. In the photo below, there is a strange yellowness to the ink, and I think it may be an artifact of my camera or the fading light.

Inside under a fluorescent light, the sheen is more visible but you have to look closely to find it. There is also evidence of a "grit" that some folks at Craftster referred to that happens when you use glossy coat spray.


I sprayed a few of the pieces with a third coat of Krylon with no noticeable difference.
Next:
These pieces have 2 coats of Krylon and group 1 has an additional coat of a brush on gloss coating called "Triple Thick." Group 2 has a clear dimensional goo called "Glossy Accents" which I have used on paper with great success.
