Identify sublimation heat transfer ink has the two most important criteria, one is the purity of ink, another is fluency of ink.

Purity of ink determines color saturation and degree of reduction after the image transfer. Fluency determine print quality and paper continuous length. Therefore, good ink is guaranteed to purity and fluency, this is the the most important indicators to identify the quality of ink. According to the production standard of ink-jet printing ink, dye particle size of general ink is not greater than 0.1 microns, below this standard will be prone to congest the printer, the ink quality is compromised.

In addition to these two important indicators, affect the quality of ink as well as precipitation problems, it will seriously affect the stability of the ink. If the ink occured precipitation phenomenon, we must use after shaking.

What is more, goog ink is almost no color problem in the printing, but poor ink will often occure color problem.
