20X30cm Resin Stamp Making DIY Photopolymer Plate 2pcs Craft Letterpress Polymer Solid Photopolymer Plate for Printing, Yellow/Green

The product worked as expected.

I have used plates (just not these ones) before and yet I was unable to get any thing to show up on this plates went from test range from10 sec to a minute then went from a minute to 30 minute test strips and was unable to get any thing to produce.

I will purchase this again.

Instructions were followed to the dot and yet the final product did not cure well and proceeded to crack and split into pieces. Don’t know what may have caused this but the final product is useless.

I have never felt the need to leave a negative review on a product before, but I feel the need warn people that this product yields very undesirable results. I ordered these for a college level Graphic Design History course to make bookplates. The material is extremely hard and the relief isn't very deep, even with hot water and lots of scrubbing. Out of approximately 40 3x4" plates made, 5 of them cracked or warped beyond repair (see photos). Only 2 of the plates created successful(ish) prints. The biggest problem wasn't even the relief depth it was that ink (both water-based and oil-based letterpress ink) could not stick to the plate. It created very inconsistent results, most of which were completely illegible.This product might work okay if your designs have thick lines and you don't need a very deep relief, but if you are looking for consistency and detail this product isn't for you.
