sublimation printing process

Sublimation is a printing transfer process which uses heat sensitive sublimation inks to permanently dye synthetic fabrics.
Small format dye sublimation printing requires a desktop printer that is capable of using dye sublimation inks, but also contains “piezo electric print heads” – and not a printer that utilizes heat in the printing process. Epson owns the patent on these print heads, although they do lease it to other printer companies, I am told.
piezo electric chargeThese print heads utilize an electric charge that causes the dye molecules to flex when the electrical current flows through it. As the charge hits the ink droplet, it forces it to spray out of the ink nozzle creating the print, but without heat. The reason this is important is because dye sub inks are heat reactive. You don’t want them turning to gas during the printing, but rather only in the transfer process as would happen with standard inkjet print heads.

One thing to note in passing…it is never necessary to print super high resolution with a dye sub printer. 1440 dpi is more than enough, and most of the time 720dpi is just fine. When the dye turns to gas in the sublimation printing process, creating the continuous tone that dye sub prints are famous for, most of the refinement that is offered by the higher resolution printing is lost because the dyes flow together during the heated dye sublimation process.
So, what do we print to when we’re creating any of the above products? First we print to a high quality transfer paper that is treated specially for the dye sublimation printing process. We don’t use a low quality paper because it affects the print quality.
