Printed Color Coated Steel and Aluminum Coil
Printed color coated plates offer decorative effects such as wood grain, brick grain, camouflage, and marble.
The printing process for color coated coils typically involves gravure printing. This method uses steel rollers laser-engraved with desired patterns to transfer ink onto the surface of the steel plate.
Initially, the substrate undergoes pre-treatment including degreasing, cleaning, and passivation. After this, a layer of matching color primer is applied to the steel plate surface. Depending on the application, primers may include polyester, polyurethane, and other coatings. After drying and curing the primer, ink is applied through printing. Printing complexity ranges from single color to multi-color patterns. Once the ink is dried and cured, a varnish coating follows, which can be polyester, High Durable Polyester (HDP), fluorocarbon PVDF, or other types.
For higher printing quality requirements, such as fluorocarbon printed color coated panels, a three-coating and three-baking process is used. This involves applying a polyurethane primer, followed by a layer of matching fluorocarbon topcoat, ink printing, and finally a coat of fluorocarbon varnish. The entire production process for printed color coated panels includes cooling, coiling, and shearing after drying and solidification of the coatings.
