The quality of a stamp impression also depends on the choice of paper. Not all paper can be stamped equally well: with a rough paper, the impression is more irregular. With a smooth paper, it is finer. Coated or sealed paper does not absorb the ink at all or only very slowly. We prefer to use an uncoated, rather smooth paper such as our Blanco Cards and Paper tags. Tip: Test the papers before stamping large quantities of them.
