Sublimation printing (dispersed) is a method of dyeing light synthetic woven materials: polyester, polyamide, acetate. Allows you to get bright colors that are resistant to environmental influences. A distinctive feature - when heated, the dispersed dye passes from a solid to a gaseous state, bypassing the liquid phase. Sublimation of the dye occurs in the temperature range 180-200 Β° C. [one]
Content
Application
- In the textile industry for dyeing fabrics with a polyester content of 50 to 100%.
Widespread in the production of flags, the application of images on textiles (t-shirts, caps, dresses in large quantities). Thanks to inkjet printers with piezoelectric nozzle control type Epson. Receive images of photographic quality 1440dpi, 2880dpi.
- In the souvenir industry, they are used on thermophilic surfaces.
It is applied to: mugs, plates, ashtrays, ceramics, glass.
Technology
Indirect ( thermal transfer ) [2] - two-phase printing.
- Print a mirror image on siliconized paper.
- Transfer to the product using a thermal press. Sublimation ink is used for thermal transfer.
It is used in small batch production. Image printing method: Inkjet, Laser, Screen, Offset, Application.
Direct - print. It is made directly on the prepared surface.
- The wet method is performed by an inkjet printer on a fabric followed by baking. [3] The printing surface is pre-treated with a polyester primer (primer). Sublimation ink is used for direct printing. It is used in large-scale and mass production.
- Dry print with a laser printer on paper. It is applied in household printers.
Commit
- Non-contact with the use of fans, infrared dryers and stimulators (peers).
- Contact with the use of calendars (rolls), tablet thermal presses , an iron is used in everyday life.
