Types of Aqueous Coating
There are different types of aqueous coatings depending on the finish you want. Each type gives a unique look to your packaging or printed design.

Dry-erase coating turns a printed surface into something you can write and erase on easily. It is often used for calendars, charts, and educational materials. It provides durability while allowing reusable writing surfaces.
- Satin Aqueous Coating
Satin coating offers a look between gloss and matte. It gives a subtle shine. Satin coatings are ideal when you want a balance between color vibrancy and an elegant, professional finish.
Aqueous Coating Process
The aqueous coating process is simple and efficient. After printing, the coating is applied over the printed sheet using a special coating unit on the press. It spreads evenly, covering the surface completely.
The sheet then passes through a heated air system that quickly dries the coating. This allows the product to be handled or packaged soon after printing. The process protects the ink and improves the look of the printed surface without adding much cost or time.
