Digital dye-sublimation transfer printing technology and materials overview

A:Technical Overview
Digital dye-sublimation transfer printing enumerate the images though using digital camera or scanner and professional library, make Colorful and hierarchy images required by computer image processing and design, then print the image designed on the paper by inkjet printer with sublimation ink, and heat up the paper with printed paper on by Digital Baking Cup Machine、hotplate machines or Roost printing machine, after few minutes, the image will transfer on souvenir like China, t-shirt and so on.

How to tell the paper transfer rate?
Among all the colors, the transfer rate of dark,red,blue etc. is lower, but our products can essential to meet customer needs, basicly can achieve the indicator of the Netherlands paper. Transfer rate depends on the ink residue on the paper.
The reason for low transfer rate

Firstly the choice of textile.

Secondly the suitable of ink, our paper basicly suit for all kind ink.

Thirdly the reason of temperature and machine, at present JV33 is good, the transfer effects of ROLAND 740K is not good.

The problem of sheet crimping
Crimping is mainly rub print head, effect the useful life of print head, and also is not convenient to cut the paper.
Reason: 

       ①The paper is affected with damp
        ②Air drying
        ③Affected by too much ink
        ④The back of paper is not coated.
        ⑤The widest the paper is, the easiest to crimp.


The paper incline to one side when printing
In the printing pricess, the paper incline to one side, the mainly reason is the coating of paper is nonuniform.
DPI
The highest is 1200*1440DPI.
