This problem occurs frequently in pad printing. It is, however, often impossible to achieve the original shade, as it cannot be mixed from the colors available in pad printing. To lessen the influence of the substrate color, the options are to: pre-print using white, double print, or triple print to increase the opacity. Each method does, however, have its drawbacks, and should be tested beforehand.
