Can Dye Sublimation Inks Print Onto Darker Substrates Or Fabrics?

Dye sublimate printing uses a CMYO inkset. This is similar to CMYK, but instead of Cyan-Magenta-Yellow-Black, it uses Cyan-Magenta-Yellow-Overprint. The overprint ends up black through some chemical process that I haven't yet figured out, but obviously, someone has because it works.Dye sublimation ink is printed onto a special paper known simply as dye sublimation transfer paper. This part of the process is similar to digital inkjet printing and is pretty recognizable in this century as a standard style of printing.

The following step is to transfer the Print to Fabric: The next step involves "marrying" the paper to the substrate, which in this case will be a piece of polyester fabric for use on a trade show display. Although any polymer-based fabric will work, the favorite material that has emerged is polyester. Polyester fabric can be anything from a sheer material to a satin to a knit and more.The paper and the fabric are then placed onto the pressure unit, which has rollers that heat to around 400ºF in this instance (there are other flat units as well as units that are used for not flat items). They are then fed through the heated rollers at a slow rate of speed.

As the paper and the cloth go into the rollers, the heat and pressure create a gaseous "explosion" and the dye is converted to a colored gas (whatever color the dye was), and the polymers expand to open like a flower in the sun, and the gas pours into these open pores, and just as quickly, as the material cools, the polymeric pores close again, but now with continuous color tones that have created a photographic reproduction of the print that was in the computer, then printed to the transfer paper, and now is permanently bonded to the fabric. Or rather has become a part of the fabric.This amazing print process has created a revolution in graphics that didn't exist before dye sublimation, and even though dye sublimation has been around for quite some time, it made its way into the display industry with the advent of digital printers, and is becoming more popular by the year now, it seems.
