彩涂板的涂布类型可分为：聚酯、硅改性聚酯、偏氟乙烯、塑料溶胶。
在世界涂料生产工艺中，彩涂板的生产工艺主要有辊涂、静电粉末涂料和筛网流。目前，辊涂是一种成熟的、应用广泛的彩涂板生产工艺。
采用辊涂机对带钢上下表面进行液体涂装，经烘烤、固化、冷却后完成产品生产。采用这一生产工艺的装置数量最多，可以高速、批量生产。该产品可用于建筑、家电、汽车等行业，并可与涂膜在同一单位上进行。辊涂机是影响辊涂机生产的主要因素之一。
辊涂机配置时，应首先考虑涂层质量。辊涂机必须可靠，能产生稳定的涂层表面。湿膜厚度是一个主要指标（干膜厚度取决于固化物在涂层中的比例）。准确控制涂层厚度是保证涂层表面质量的前提，也是降低涂料消耗和生产成本的前提。

The coating types of color coated plate can be divided into: polyester, silicon modified polyester, vinylidene fluoride, plastic sol.

Coating production process in the world, the production process of color coating plate mainly includes roll coating, electrostatic powder coating and screen flow. At present, roller coating is a mature and widely used production process for color coated plate.
The liquid coating is applied to the upper and lower surface of the strip steel by the roller coating machine, and the product production is completed after baking, curing and cooling. The number of units adopting this production process is the largest, and the units can be produced in high-speed and mass production. The products can be used in construction, home appliances, automobiles and other industries, and can be carried out on the same unit with the film coating. Roller coater is one of the main factors that affect roller coater production.
When the roller coater is configured, the coating quality should be considered first. The roller coater must be reliable and can produce stable coating surface. The wet film thickness which can be controlled by the roller coater itself is a main index (the dry film thickness depends on the proportion of solidified substance in the coating). Accurate control of coating thickness is not only the premise to ensure a good coating surface, but also to reduce paint consumption and production cost.
