Hot Melt Ink Rolls are designed to be used in high speed date coding and marking printers which use a stamp on a rotating drum which contacts a heated urethane roll impregnated with an ink / paraffin formulation. Once the print head is covered with the hot ink, the rotating drum deposits the ink mixture on the label or packaging substrate.

The ink rolls themselves are hard and dry to the touch at room temperature. However, when installed into the printer, the roll itself is heated and the ink becomes liquid. Once deposited on the substrate, the ink dries almost instantly and creates a mark that is permanent and visually readable. The result is a visually readable date code, which is simple and extremely cost effective.
