What is sublimation heat transfer technology?

Sublimation transfer is the portraits, landscapes, text and other graphics using heat transfer ink inkjet printer with mirror reversal print on the sublimation transfer paper,Then heat transfer machine (Heat press machine) heated to about 200 ℃,The heat transfer ink on the sublimation paper will infiltrate into the substrate in the form of gasification,, So that the color of the paper images vividly transferred to textiles, porcelain cups, porcelain plates, porcelain, metal and other materials on a new technology.

To use a dedicated dye-sublimation transfer ink, be sure to use sublimation transfer ink, this ink produced with disperse dyes, the transfer temperature will produce sublimation and dyeing with the substrate. Good quality dye-sublimation ink nozzle should not be blocked, lifelike, good stability.

Adjust the appropriate color concentration in the computer to adjust the color concentration, to avoid excessive ink is not easy to dry situation, adjust the need to check the effect of heat transfer.

Sublimation transfer digital printing technology

Textiles digital printing is increasingly mature, and is eating the traditional screen printing market. With the increasing number of flat-panel machines and professional printing machines on the market, the digital printing market gives people a glimpse of a rich blueprint for getting rich.However, due to the professional digital printing equipment and processing procedures are very cumbersome, printing results are unsatisfactory, so that personalized digital printing has been unable to find the entry point.

Textiles digital printing is increasingly mature, and is eating the traditional screen printing market. With the increasing number of flat-panel machines and professional printing machines on the market, the digital printing market gives people a glimpse of a rich blueprint for getting rich. However, due to the professional digital printing equipment and processing procedures are very cumbersome, printing results are unsatisfactory, so that personalized digital printing has been unable to find the entry point.

Thus, many people in the case of digital printing is not familiar with the hope that the use of flat-panel printing pigments or even dye ink to obtain qualified printing products, but if not professional fabric processing is difficult to obtain satisfactory results, which is mainly fabric needs Pretreatment and post-processing can be used.

It is often overlooked and the most mature digital printing technology is sublimation transfer digital printing, that is, the use of thermal transfer ink through any one inkjet printer, mainly piezoelectric inkjet printer, Heat press machine first sprayed to the paper And then heated to 180 ° C after the transfer pattern onto the fabric.Sublimation transfer digital printing effect is very good, mainly because the pattern will not be blurred because of ink drift, but also bright colors of dye and washable and so on.

Sublimation transfer digital printing is mainly used for chemical fiber or blended fabric, the cotton can not print. As a digital printing of cotton products, textile printing pigment ink is the best choice, but the general need for special pretreatment of cotton fabric to reduce the penetration of ink to prevent the screen blurred, and then after high temperature steam fixation. sublimation paper However, the textile pigment ink for digital printing can not achieve the effect of thermal transfer.
At present, the real large-scale use of commercial and industrial digital printing technology is mainly thermal sublimation transfer printing, and in the last year began to sweep the world.

This is mainly due to China’s launch of the thermal transfer ink price is very low, so that large-scale digital printing costs are no longer expensive, previously a major US companies and South Korean companies monopoly ink market, expensive, Sublimation ink for large quantities of printing costs simply do not come down. Therefore, the intention to engage in digital printing industry awareness can be considered at the same time using thermal transfer and textile pigment direct injection, after all, the largest proportion of chemical fiber products.

Application of thermal transfer ink

Heat transfer ink is mainly used for polyester fabric, polyester deformation fabric low elasticity, triacetate fiber, nylon fabric, acrylic, diacetyl fiber, polypropylene clear, etc., can also be used for shoes and hats, crafts, blue foot volleyball leather products sporting goods The Sublimation thermal transfer ink for a variety of offset printing presses, printing materials: coated paper, coated paper, offset paper, cardboard, and so on. Can adapt to high, medium speed printing requirements, fixed speed, on the machine performance.

Heat transfer ink printing advantages: excellent printing, ink non-toxic, low odor, good adhesion, non-stick hand; toughness, good fastness, wear-resistant washing. Can achieve three lightfastness, the ink does not crack, good elasticity, feel good, ink leveling good sticky, environmentally friendly low odor, sublimation ink  can achieve export requirements. Light fastness, color than ordinary bright.

Before the use of a small sample for the plate making printing, such as the deviation is not large, and then determine the sample plate printing. Because sublimation ink for the gas phase coloring, it can not be printed according to the proportion of ordinary printing.

Which is better for sublimation inks, low temperature or high temperature?

Korean sublimation ink require temperature around 180-210 ℃to finish heat transfer process. Recently, some sublimation inks just need to heat up around 130-160 ℃to heat transfer on ceramic mugs, metal, wooden materials and polyester fabrics. However, which one is better? Most of us regard that though Korean sublimation inks require higher heating temperature, the heat transfer efficiency reach 95% by using special sublimation paper. In addition, Korean sublimation inks is recognized as non-color deformed and non-blocked nozzle.
Domestic sublimation inks can heat transfer high efficiency sublimation materials without special sublimation papers, but in low price. But because of its second time sublimating, its color fastness is not very good. Therefore, when you choose the correct sublimation inks, pls note.Articles from:http://www.printtotalsolution.com/instance-detail.php?CaseId=65

Cups, plates on the heat transfer process

Use a printer that prints sublimation ink, inkjet paper, or heat transfer paper.

(1) Here the cup, the plate is a special cup of heat transfer, plate, before doing a coating. Cup, the appearance of the plate to be with the cup heat press machine, heat plate machine mold consistent;

(2) print the size of the picture to be with the cup,heat transfer machine the size of the transfer position on the plate or smaller, the print must be selected to print;

(3) picture facing the cup or plate, placed in the correct position, the cup also need to use the tape will stick to stick, try to make the picture with the cup without the middle of the gap. Porcelain on the heat transfer temperature is higher, the time should be longer;

Heat transfer of the specific operation seems simple, up to a few minutes to complete, but because of the different pictures, the use of differen Heat transfer paper, transfer the different ways, especially the substrate properties,laser transfer paper  thickness, color and even origin , Resulting in the transfer of the temperature and time of the different, difficult to master the best results.

The core technology of digital heat transfer – heat transfer ink

The core technology of digital heat transfer – heat transfer ink

Heat transfer color printing ink (water-based) with sublimation ink , other chemical additives and water from the preparation.As in the ink market is accustomed to the ink is divided into oily ink and water-based ink,So the product appears in the early days of the market that the product is called heat transfer color printing ink, because this ink is water-based ink, and now people are accustomed to known as sublimation printing ink or heat transfer ink.

Identification of heat transfer color printing ink has two most important standards

(A) is the purity of the ink, the purity of the ink to determine the image after the color saturation, reduction degree..

(B) is the fluency of the ink that is the length of the print length and area. Fluency determines print quality and continuous length of transfer paper

A solution to the problem that the heat transfer ink is not black enough

Heat transfer ink is mainly used to assist in printing some of the more deep color of the solvent, such as printing black cloth;The use of digital printing technology to print pure black fabric is not an easy thing,In the printing process will appear ink desalination or printing uneven phenomenon;The heat transfer ink transfer image colorful, rich layers, the effect can be comparable with the printing,The difference is that the thermal transfer ink is in the high temperature of the thermal transfer ink heat sublimation, will not form a film on the surface of the media, and the image does not fall off, no cracking, and light resistance is very strong, a long time will not fade The.

Heat transfer ink is the heat Sublimation ink, printed on the special paper, through the heating, you can in the shortest possible time to produce the image of fine porcelain, metal, silk, chemical fiber fabrics and other materials, photo-quality, Image is clear, and can be permanently preserved, very suitable for personalized development of the market needs;

If the ink when the ink is not enough black when the phenomenon, we need to consider the following:

1, you use the method is correct, whether there are bad steps. Or digital inkjet machine and heat press machine problems;
2, you use the heat transfer ink is genuine or improper preservation caused by deterioration;
3, your printed cloth is not in the printing range of heat transfer ink
