Our products and apparel are produced via the dye sublimation print process which involves heating or curing the inks into the fabric as opposed to an "iron-on" transfer.
Dye-sublimation printing is a digital printing technology using full color artwork that works with polyester and polymer-coated substrates. Also referred to as digital sublimation, the process is commonly used for decorating apparel, signs and banners, as well as novelty items such as cell phone covers, plaques, coffee mugs, and other items with sublimation-friendly surfaces. The process uses the science of sublimation, in which heat and pressure are applied to a solid, turning it into a gas through an endothermic reaction without passing through the liquid phase.
In sublimation printing, unique sublimation dyes are transferred to sheets of “transfer” paper via liquid gel ink through a piezoelectric print head. The ink is deposited on these high-release inkjet papers, which are used for the next step of the sublimation printing process. After the digital design is printed onto sublimation transfer sheets, it is placed on a heat press along with the substrate to be sublimated.
In order to transfer the image from the paper to the substrate, it requires a heat press process that is a combination of time, temperate and pressure. The heat press applies this special combination, which can change depending on the substrate, to “transfer” the sublimation dyes at the molecular level into the substrate. The most common dyes used for sublimation activate at 350 degrees Fahrenheit. However, a range of 380 to 420 degrees Fahrenheit is normally recommended for optimal color.
The end result of the sublimation process is a nearly permanent, high resolution, full color print. Because the dyes are infused into the substrate at the molecular level, rather than applied at a topical level (such as with screen printing and direct to garment printing), the prints will not crack, fade or peel from the substrate under normal conditions.
Therefore, the ink and subsequent print graphic is as much of the garment as the fibre itself meaning no cracking, peeling or fading.
The blanks that we use for decoration are sourced directly from Vapor Apparel in the USA. We use these as they are premium sublimation material ... 100% polyester
(a requirement of sublimation substrates) but give the look and feel of high end cotton rather than cheap, inferior far east versions.
Add to these inks from Sawgrass Technologies used in commercial proofers and you have the reasons why we are happy to offer lifetime guarantees on our shirts. In the highly unlikely event of your print or shirt developing a defect, simply drop us a line and return the item to us and we will offer you a replacement free of charge or a refund ... no questions asked!
