1 Tips on how to adjust the color of thermal transfer inks, so that color adjustment is no longer a problem
In the thermal transfer process, four-color overlay is generally used for printing. There are four basic colors, namely black, red, blue and yellow. These four colors can be mixed into thousands of colors.

In actual printing, we often encounter problems of one kind or another in the color adjustment process. If we do not understand the relevant knowledge of ink color, it is difficult to solve these problems. The following is a brief introduction to several tips for adjusting the color of thermal transfer inks, so that color adjustment is no longer a problem!

2 Choose high-quality thermal transfer inks
To choose high-quality thermal transfer inks, the properties and hues of the original inks of different manufacturers are different. It is best to choose an ink product from a manufacturer. Before mixing, you need to understand the color saturation and viscosity of the ink. When the mixed ink is too thin or too thick, it is unqualified. The mixed ink should have a certain viscosity and fluidity, so that high-quality products can be printed.

3 Appropriate solvent is the key
In the process of mixing thermal transfer ink, it is key to choose the right solvent; when the surrounding production environment temperature is high, slow-drying solvents should be used, so that the evaporation speed is relatively slow. During this evaporation period, the hue of the ink can be observed and adjusted in time.

4 Matching of primary and secondary inks
When mixing thermal transfer spot color inks, pay attention to the matching between colors, confirm the main color tone of the printed product and the secondary color tone contained, the main color ink is used as the basic ink, and other inks are used as color-adjusting inks. In this way, the mixing of spot color inks will be faster, more accurate, and the amount can be better controlled.

5 Pay attention to the amount of black ink
When adding black ink, pay special attention to the amount added. Among all thermal transfer inks, black ink has a relatively strong coloring power. When too much is added, the color of the ink will deepen, forming a dirty phenomenon, and it will prevent the reflective degree of the substrate. Then you need to add quite a lot of other color inks to adjust the color. When the ink is adjusted, the color sample printed on the machine should be carefully compared with the color draft, and the color error should be corrected in time.

6 How to solve the uneven thickness of the ink layer
During the production process of thermal transfer ink, the thickness of the ink layer often appears uneven. The reason for this phenomenon is that the thermal transfer ink particles are too large or the dots are blocked. How to solve this problem? Teach you two tips:

a. The thermal transfer ink should be fully stirred and evenly used to avoid uneven pigment particles. If conditions permit, you can also filter the ink with a filter before use, so as to reduce the particles of the pigment.

b. Before starting printing, the surface of the printing plate must be cleaned first. In addition, after printing, the ink in the printing plate dots must be rinsed clean with a solvent and wrapped with a protective cover to prevent dust particles from clogging the dots and affecting the pattern quality of the next printed product.
