How is sublimation paper made?

In the beginning, the sublimation paper used in the sublimation technology of heat transfer can only rely on imports. The technology has been developed rapidly after being introduced to the country. However, most of the domestic manufacturers of sublimation paper have insufficient technology, and the equipment is relatively backward, and can only produce low-to-medium grades. Sublimation paper is used for production that does not require high sublimation transfer printing. For the higher-requirement sublimation transfer printing, it is necessary to use relatively high-priced imported paper. The main reason is that the transfer rate of domestic sublimation paper production is low. The drying speed of the sublimation paper after printing ink directly determines the efficiency of the sublimation transfer. The fast-drying speed can make the user convenient to use, can facilitate continuous printing, and improve the delivery speed. Usually, after sublimation paper is printed with water-based ink, it relies on the coated water-absorbing material and base paper to absorb the moisture in the ink, to achieve the goal of drying. The drying performance of the sublimation paper is mainly related to the coating formula and the water absorption of the base paper. So how is sublimation paper made? Here are some answers.

The manufacturing method of quick-drying sublimation paper.

Sublimation paper is the method of using inkjet paper without adhesion film on the surface of the substrate, so the hand feeling and visual effect of the pattern of sublimation paper are far better than ordinary ink and transfer paper. The heat transfer products made of sublimation paper have the advantages of color, no fading, no cracks, good air permeability, etc., which have become popular products in the world today. Newspapers such as photo banners, street light flags, ribbons, handbags, luggage, sea bags, wall charts, double flags, clothing, tiles, glass, etc. made of sublimation paper stand out in the fierce market competition.

To make quick-drying sublimation paper, it is necessary to choose base paper with strong water resistance. First, apply a sublimation transfer ink-retaining coating on the front side of the base paper. Then, a coating that is beneficial to improve the water absorption of the paper is coated on the back of the base paper. The size of the back coating is water + surfactant or water + starch + surfactant. The quality of the surfactant is percentage is between 0.5% and 5%, and the mass percentage of starch is between 0.5% and 3%.

Two printing methods for sublimation paper.

There are two printing methods for sublimation paper, one is sublimation transfer printing and the other is thermosetting transfer printing. The sublimation method of sublimation paper refers to the printing of the color paste produced by thermally sublimated disperse dyes into printing paper by screen or gravure and then transferring the pattern on the printing paper to the required medium. The heat-set transfer method of sublimation paper refers to the use of thermosetting ink (also known as hot melt glue) to make a plate with a gravure plate and then print it into a printing paper by a thermal transfer paper printer, and then transfer the pattern on the printing paper to the product. The two printing methods of sublimation paper have obvious differences in application. The heat-set transfer method of sublimation paper is mainly used on chemical fiber fabrics and hard materials coated with thermal transfer coating. The sublimation transfer method of sublimation paper is mainly Applied to pure cotton products. The difference in the texture of the two sublimation paper printing methods is that the original texture of the material is not changed after the heat-set transfer, and the hand feel and look are good. After the sublimation transfer method, a layer of jelly is formed on the surface of the attachment, which has a poor hand feeling and is airtight.

The advantages of sublimation paper.

Sublimation paper needs to use sublimation ink. Dye sublimation ink (also known as thermal transfer ink) is a digital ink made of low energy consumption and easy sublimation disperse dyes, which can be printed on sublimation paper. Through heating, the image can be made into exquisite porcelain, metal, silk, chemical fiber cloth, and other materials in the shortest time, which is very suitable for the personalized development needs of the market and environmental protection. Sublimation paper is suitable for cloth, leather, metal, wood, ceramics, glass, plexiglass, PVC board, etc. The characteristic of sublimation paper is that the transfer image is bright in color, rich in layers, and the effect is equivalent to printing.
