What's the Requirement for the Sublimation Transfer Printing Process?

Among the digital printing processing technologies, the sublimation transfer printing technology is widely used! The patterns printed by the sublimation printing technology are relatively rich in color, content and performance, and are very popular!

However, a good printing effect must have matching materials and process conditions, as is the sublimation transfer technology!

Nanjing Skyimage as a professional digital printing equipment supplier, will share with you today: the four characteristics of the sublimation transfer technology process requirements!

First, the requirements for sublimation transfer paper

Good sublimation transfer paper with a good printing process can print good patterns and items!

Sublimation transfer technology, the requirements for heat transfer paper:

1: The surface is dust-free, burr-free, defect-free, dimensionally stable and can control the gas permeability.

2: Can meet the printing requirements. Easy to release dyes, high thermal strength, low dye gas permeability, can meet the transfer requirements.

3: The amount of transfer paper is 50~70g/m^2, and the natural polymer materials are starch, gum arabic and sodium alginate.

Second, the requirements for transfer paper connecting materials

The requirements for sublimation transfer technology and binders are somewhat different from traditional binders!

The requirements for it: low affinity with dyes, easy release of dye gas, suitable printability, preservability and thermal transfer adaptability.

Third, the requirements of the dye sublimation ink formula

The key to the production of sublimation transfer paper is to prepare for sublimation ink. According to different requirements, the dye content ranges from 5% to 18%.

Fourth, the requirements for disperse dyes on heat transfer paper

The requirements for disperse dyes are:

1: Sublimation transferability and permeability are good; reach a certain fastness index;

2: The dye gas and the molecule have a strong force and can diffuse into the fiber. The dye sublimation temperature is below 200 °C.

3: Under the operating conditions, the dyes of each color have good compatibility and achieve the purpose of coloring the three primary colors.

Only by meeting the requirements of the above four categories, sublimation transfer technology can really play its own advantages, through its own process technology, print a more perfect pattern works!

Digital printing processing, different processes have different characteristics, meet their characteristic requirements, coupled with professional proofing technology to achieve the most perfect digital printing!
