Pad Printing Ink Thinning Rule - 20 Percent Tops
Don’t try to over-thin by stretching out the life of pad printing inks with excessive solvents. This is false economy. It weakens the ink and can shift the color and opacity. Maximum recommended thinner ratio is 20%. Most applications are fine at 15% thinner. Cutting corners by extending your printing ink does not necessarily save money. Plus, you are risking the most important goal of your finished decorating job: a quality image!
