Tin printing
Tin printing refers to the offset printing process for metal .
Usually tin or aluminum sheet is printed. In order to make the sheets more receptive to the application of paint, painting is usually carried out before the actual printing, which can vary depending on the type of sheet.
Magnets and loosening blowers are used for better separation at the sheet feeder . The recently introduced multi-color machines with four to six colors will be modified accordingly beforehand. The paints are dried in chain ovens for 12 minutes at 160 ° C to 180 ° C. If the printing inks are appropriately selected, drying is also carried out using UV radiation. Printing machines from Koenig & Bauer MetalPrint (formerly KBA-MetalPrint) are mainly used on the German market .
To protect them during further processing (cans, crown corks, twist locks), the panels are provided with a clear protective varnish.
