Review on 5x5 Speedball Gel Printing Plate - Optimal Size for Efficient Printing by Amy Brown

Nowhere on the packaging or in the product description does it say DO NOT USE WITH OPAQUE WHITE PLASTIC. So I tell my friends who color with alcohol DO NOT USE WITH CEILING WHITE PLASTIC. This special substrate adheres directly to the plate. I had to soak the slab in water for 15 minutes and even after that clumps still flew off the slab when I tried to remove it. I don't know if the opaque white plastic will stick to other brands of gel pads and don't want to ruin my discovery of other plates. However, he sticks to it. This combination is a NO-GO situation.
