Water transfer technology process introduction

There are many types of substrate shapes and materials that can be transferred by water transfer technology. For example, water transfer technology is a process technology that uses water pressure to coat images and texts on the surface of an object for transfer printing.

According to the realization characteristics of water transfer, it can be divided into water drape transfer and water mark transfer. Water transfer technology adopts water transfer technology to decorate most of the daily necessities, such as plastic, metal, glass, ceramics, Wooden plane and molded body. According to whether coating is required before transfer, printing materials can be divided into the following two categories.

(1) Materials that are easy to transfer

Some materials in plastics have good printing performance, such as polystyrene (PS), ABS, plexiglass, polycarbonate (PC), polyvinyl chloride (PVC) and other materials. They can be transferred without coating. The transfer principle is the same as The printing principle is similar.

(2) Materials that need to be coated, non-absorbent materials such as glass, metal, ceramics, and non-polar materials such as polyethylene and polypropylene need to be coated with a special coating before water transfer can be performed. Coatings are paints that have good adhesion to transfer materials, which can be processed by screen printing, spraying, or rolling. From the perspective of printing, coating technology solves the problem of surface decoration for many materials that cannot be printed. There are many popular transfer processes, such as sublimation transfer, hot melt transfer, ceramic decal transfer, and pressure-sensitive transfer. Printing, etc., all need to be coated on the surface of the printing material.

Most of the printing methods of water transfer technology are decorative printing for flat or nearly flat substrates.
