We have printed these guitar picks with UV curable ink instead of solvent ink. The major difference is the adhesion to all plastic materials (including delrin.) This UV inkjet ink also has a white ink. White ink creates a base for the colored ink, allowing the colors to really stand out. The ink is a UV LED ink, meaning the ink is cured by low temperature light. The low temperature ensures no heat damage to the product.
