Plant And Process For Pre Coating And Printing On Metallic Strips

Abstract: The invention relates to a plant and a process for pre-coating (111) and subsequent digital sol-gel inkjet printing (122) on metallic strips, wherein on the dried ink a protective clear coat (124) will then be applied. The core of the invention lies in the fact that printing is of the sol-gel ink type and pre-coating (111) is no longer carried out by the separate application of two coats, a primer and a base coat, with relative drying and cooling phases of the coats, but by the application of a single coat that combines the functions of primer and base coat. In addition, printing with a special sol-gel type ink that does not require UV treatment, but only a simple drying of the ink after application, simplifies the process even further.
