Hi there, clear stamps can be the hardest to get good images from. First off, a good tip is to go over the surface of the stamp with low-tack tape, to remove any residue from the manufacturing process. A lot of people on here will recommend lightly rubbing over it with a pencil eraser too. Next is your ink- Versafine generally will give you the best impression with polymer stamps. A lot of people also recommend Chalk inks for a good coverage.
Here on my blog I did some ink comparisons with an assortment of inks on clear photopolymer stamps- you can see the Versafine fared best. I was mainly trying out a new pad available over here called Clearly Better- but I found it no better than the Versafine, which is what I always use. Hope this helps.
