Permanently printing ink on aluminum is a difficult task, as the difference in coefficients of expansion between the ink and the metal often causes the ink to delaminate. Many applications require permanent printing in order to maintain traceability over the life of the product. This problem is solved when using Sanford Process’ SANFORD PRINT™ technology.
The SANFORD PRINT process embeds the ink within the aluminum by putting it into the anodic pores of the material, below the surface. The ink is then permanently entrapped by sealing. SANFORD PRINT addresses a deficiency of conventional screen and pad printing for certain applications where the ink is at risk of delamination and/or chipping. Unlike conventional printing where the ink dries on the surface of the anodic coating, the SANFORD PRINT methods are permanent and non-destructible.
Unlike similar techniques, SANFORD PRINT printing technology, combined with the high porosity achieved with Sanford Process’ QUANTUM® process, leads to extremely high print density. The result is bold, clear, permanent printing.
