Due to the fact that flexible plate printing belongs to ink-based printing, it is very easy to cause paper swelling when it comes into contact with water or large amounts of ink. This can lead to unevenness in the local area after printing, which in turn affects the next printing step. It can also cause wrinkles on the napkin paper, and the easily swollen substrate material can exacerbate the fluctuation in tension, leading to larger fluctuations in registration accuracy, making it difficult to produce good products. Furthermore, due to the poor moisture resistance of toilet paper, it is easy to transfer loose fibers from the paper to the plate after contact with the plate, causing fuzzing of the plate, making it impossible to continue printing, which further affects the quality and yield of the finished product. Ordinary napkin paper is made by laminating two or three layers of non-wrinkled toilet paper with a joint, then going through flexible plate printing, and then through tooth-shaped rollers.

The simple combination of paper foil roller pressing flowers, most of the napkins in China belong to this. Nowadays, most napkins on the table in Europe and the United States are micro-coated composite materials before printing. Such napkins are flat, smooth, and have a texture and sense of thickness, and there is a special product, that is, micro-coated composite products. The printing layer is in the middle of the three-layer structure, so it has a good sense of texture and flexibility, and the product surface is more beautiful.

Domestic printers should strive to change the method of pressing and compressing the napkins to a micro-coating composite before printing, so that the quality of the napkins can make a qualitative leap. In addition, domestic napkins should also improve the materials to narrow the gap with foreign products. For example, using higher purity wood pulp to produce the original paper, adding enough moisture-resistant agents, and striving to meet the printing requirements in terms of surface smoothness and moisture resistance strength, etc.
