UV-blocking hot melt ink jet inks for printing on flexible and other media. A UV-blocking hot melt ink jet ink for flexo-graphic plating comprises a wax, a plasticizer, a UV blocker, and a dye. Such an ink is flexible and durable, gives good printing quality, and is also removable from the flexo plate substrates during the wash out cycle of the flexo-plating process. Another UV-blocking hot melt ink jet ink for printing on silk screens comprises a wax, a fatty acid, a UV blocker, and a dye. Such an ink is readily removable from the silk screen without harming the screen. |
