Core structure of sublimation paper

1、 Base paper

Base paper is the basic supporting part of Sublimation Paper. Its quality directly affects the stiffness, strength, and subsequent transfer effect of the transfer paper.

The base paper is usually made of specific paper materials, such as common polyester fiber paper. Polyester fiber paper has good strength and toughness, can withstand various physical tensile forces during the transfer printing process, and is not easily damaged. This is crucial for ensuring the integrity of the paper during the transfer process, so that the pattern can be accurately and completely transferred to the target object.

And the surface smoothness of the base paper is also crucial. If the surface of the base paper is uneven, it may cause wrinkles, blurriness, and other problems in the pattern during transfer printing. So manufacturers producing base paper will adopt advanced papermaking processes, strictly controlling the thickness uniformity and surface smoothness of the paper. -Generally speaking, the thickness error of high-quality sublimation transfer paper is controlled within a very small range, and the surface smoothness can also reach a high standard to ensure that the ink can be evenly adhered and transferred during transfer printing.

2、 Coating

The coating is the core part of sublimation transfer paper, which plays a decisive role in the transfer effect of patterns.

The coating mainly includes a coloring layer and an isolation layer. The chromophore contains dyes that can sublime at high temperatures. These dyes will directly transform from solid to gas under the high temperature of the sublimation transfer printing equipment, thereby achieving color transfer. Different dye formulas will determine the type and vividness of the transferred colors. For example, to transfer a bright red color, a specific red color is required

 

The dye formula can only achieve the desired color effect by precisely adjusting the composition and proportion of the dye.
