For those that aren’t aware, sublimation is a poly-specific technology, which means all of the thousands of hard substrates available to be sublimated have been through a polyester coating facility, and the garments or fabrics have a 50 percent or higher poly content.
The polyester in the garment is directly related to the color retention you receive. We get a lot of customers using 50/50 garments because those offer a vintage look, whereas others want the pop of 100 percent color retention, in which case, there are a number of lines made specifically for sublimation on high- or all-poly content.
