The printing production line of colored aluminum sheet is a complete of production equipment for colored aluminum sheet, and the process is as follows: make the aluminum coil strips be subject to surface degreasing treatment, then apply multi-layer organic coatings (e.g., nano-coating, self-cleaning coating, scratch-resistant coating, fingerprint-resistant coating etc.) on the strip surface by means of continuous roller coating, next, overprint multi-color patterns, and finally bake and cure to form composite material. The production line is composed of equipment of uncoiler, sewing machine, storage machine, degreasing and washing unit, roller-coating machine, printing machine, curing furnace, shear, coiler etc.
