A new generation of sublimation transfer printing ink

Dye sublimation printing is one of the most popular product decoration methods because it is a versatile and usable process.

The digital sublimation transfer printing can be successfully transferred once, without consuming a large amount of ink, which saves time and saves money. When the transfer is performed, for example, transfer to a fabric, the substrate is subjected to a high temperature of 200° C. on the transfer machine for 3 OS (seconds) to complete the transfer. In this process, the dye changes from solid to gas and then back to solid.

The greatest advantage of dye sublimation transfer is that dyes can be incorporated into the fibers of polyesters or fabrics. In screen printing, the solvent or ink forms an ink layer on the surface of the fabric. Therefore, the printed product after the sublimation transfer printing is very soft and does not feel the presence of the ink layer. In addition, since the ink is dried during the transfer process, the life of the image is as long as the life of the garment itself.

Today, sublimation transfer inks have been able to print very thin ink layers on any product, and the number of prints is not limited. Since Kyocera dyes are 100% organic dyes, the dyes can diffuse in water, and the inks can be transferred only by heating, which means that no chemical agent is used on the human body in digital dye sublimation transfer printing. And the environment is not poisoned.

The only disadvantage of sublimation transfer is that the choice of color is limited and it is difficult to match the Pantone color standard. In order to overcome this defect, Sabina International of the United Kingdom has recently developed a new sublimation transfer ink, Dyestar, which has been gradually completed after more than 2 years. Its introduction provides a technologically advanced technology for the ink market. Ink system.

Ink matching

Dyestar ink series includes the following: CMYK-1 is used for small digital printers or most four-color printing processes: CMYK plus LM and LC six-color system - six-color system with color gamut larger than traditional CMYK plus orange and green It's wider; there's also a Hexachrome six-color system with an orange and blue color that matches the deep blue. The above several ink systems can meet the various needs of users.

Special transfer machine

Sabina International also specializes in digital printing equipment for the dye sublimation process, which is based on the original printing press for maximum productivity. The newly-remodeled sublimation transfer machine has added a conveyor that can hold 6X1kg ink tanks. Each color ink can be supplied directly and independently. On the output side of the press, a drying device was added. After the dye-sublimation ink is dried, the print is automatically wound on a reel located under the drying cabinet. The transforming machine is compact, fast and durable. Its feeder can carry a roll of 50-meter-long transfer paper. The printed and dried printed product is automatically wound on a spare shaft. This operation does not require special training technicians.
