What is the sublimation ink?

Sublimation ink is a kind of thermal transfer ink. This process is to print the ink on paper and then transfer it to the substrate. According to the sublimation characteristics of the dye, after the sublimation ink encounters high temperature, the sublimation of the ink is inside the substrate instead of on the surface. Under certain conditions of temperature, pressure, and time, the sublimation ink is sublimated into a gas phase and transferred from the printed paper to the fabric (such as sportswear, non-woven bags, clothing, handicrafts, layered metal, etc.), enters into the fabric through gas-phase sublimation and diffusion, to achieve the purpose of coloring, and there is no hand feeling after printing. The following will focus on the topic of what is sublimation ink.

The main contents are as follows

l Offset printing characteristics of sublimation ink

l The scope of application of the thermal transfer process

l How to use sublimation ink and matters needing attention

Offset printing characteristics of sublimation ink

Sublimation inks are available in red, yellow, blue, and black series. The printing materials include coated paper, coated paper, offset paper, and cardboard. The scope of application of sublimation ink is mainly suitable for single-sheet paper feeding single-color presses, two-color or multi-color offset printing presses. In addition, the sublimation ink has two major product characteristics: First, it can meet the needs of medium and high-speed printing. Second, under normal circumstances, it can ensure that there is no conjunctiva in the ink fountain of the printer for 36 hours.

Tips for the use of sublimation ink: print out a small sample for plate-making and printing before use. If the deviation is not large, then confirm the sample manufacture for plate-making and printing. Because the sublimation ink is colored in the gas phase, it cannot be printed at a normal printing ratio.

The scope of application of the thermal transfer process

The thermal transfer process can also refer to the sublimation ink suitable for the transfer of cloth and the surface of hard objects that have been coated. The fabric is mainly polyester and polyester cotton, and the hard objects are resistant to high temperatures, such as film, metal, glass, porcelain, porcelain cups, PVC, etc. As long as the sublimation ink transfer materials are resistant to high temperatures, they can be used with thermal transfer coatings. Layers can be transferred through a dedicated ironing machine to complete the image transfer.

How to use sublimation ink and matters needing attention

First of all, under normal circumstances, it can be used directly on the machine;

Secondly, due to factors such as temperature, paper, printing speed, etc., it can be adjusted according to the following rules;

(a)To accelerate drying, mixed desiccant can be added, the amount is 0-2%;

(b)Equipped with special sublimation ink for indifference;

(c)Adjust the fluidity of sublimation ink, you can use #6 printing varnish, the dosage is 0-5%;

(d)Reduce the viscosity of the paper, basically keep the fluidity unchanged, a detackifier can be used, the dosage is 0-5%;

(e)At the same time, reduce the viscosity and viscosity of the sublimation ink, add 52-94, and the dosage is 0-5%.
