Thermal sublimation transfer printing technology is widely used in digital printing processing. The patterns printed with thermal sublimation printing technology are relatively rich in color, content and performance, and are highly sought after by many people.
But a good printing effect must be matched with the materials and technological conditions, such as thermal sublimation transfer printing technology.
I. requirements for transfer paper
Good transfer paper with a good printing process to print out good patterns, goods.
Heat sublimation transfer printing technology, requirements for transfer paper:
1: no dust, no burrs, no defects, stable size and air permeability control
2. It can meet printing requirements. It is easy to release dyes, high thermal strength, low permeability of dye gas, and can meet transfer requirements
3: transfer printing paper quantitative 50 ~ 70 g/m ^ 2 advisable, natural polymer material is starch, gum Arabic, and sodium alginate, etc
Ii. Requirements for transfer paper connection materials
The requirements of thermal sublimation transfer printing technology and connecting materials are somewhat different from those of traditional connecting materials.
Requirements: low affinity with dye, easy to release dye gas, suitable printing, preservation and heat transfer adaptability.
Iii. Requirements for the formula of transfer paper ink
The key to the production of screen printing heat sublimation transfer paper is to prepare ink. According to different requirements, the dye content varies from 5% to 18%.
Requirements for disperse dyes on transfer paper
The requirements for disperse dyes are:
1: good sublimation transfer and permeability; Achieve certain fastness
2: dyeing between gas and molecules, has a strong force, and can spread to the inside fiber. Dye sublimation temperature under 200 ℃ is more appropriate
3. Under operating conditions, the color dyes blend well to achieve the purpose of primary color coloring
Only by meeting the above four requirements can thermal sublimation transfer printing technology give full play to its advantages and print more perfect patterns through its own technology.
Digital printing processing, different processes have different characteristics of the requirements, meet their characteristics, with professional proofing process to achieve the most perfect digital printing.
