Sublimation Systems

Sublimation is the process of a solid changing state directly into a gas, thus bypassing the liquid stage. An example of this is dry ice. Everyone has seen blocks of dry ice and the vapour they give off, but no liquid. Dry ice sublimates.

When it comes to sublimation transfers, the ink is actually a microscopic solid particle, which is suspended in the liquid (essentially water) that is the liquid ink we see. When printed onto paper, the solid particle sits on the paper. When heated beyond 160C, this particle becomes a gas and binds chemically with the polyester of the coating (in the case of hard surfaces) or the polyester fibres in the case of fabrics. Sublimation needs special ink, paper and substrates with a polyester coating or fabrics that are synthetic to work. Sublimation should not be confused with dye-sublimation which is a different print technology using ribbons instead of liquid inks.

A product printed with the sublimation process, is completely smooth to the touch and due to the nature of the solid to gaseous phase, the image is smooth, there are no dots to see, thus images like a photo of a person as superb. Sublimation is for light / white items only and will not work on a dark of black product (the result will be like writing with a pen onto black paper – You can sort of see something but it’s not easy).

When it comes to printing onto not synthetic products (like T-shirts), there are two special processes for cotton fabrics. The one is a paper which traps the ink and allows it to be transferred to cotton. The other is a special white substrate that is printed with the sublimation ink and this white substrate then transfers and sticks to the shirt. Whilst washability is good, it’s nowhere near as good as sublimating onto a polyester fabric. Fabrics printed with sublimation are permanent, not even bleach will remove them. A ll sports wear for example is sublimated. There is no other way to decorate them. No one has ever seen a polyester sports shirt wash out.

To print sublimation, a printer loaded with sublimation inks is required along with sublimation transfer paper. Unlike other companies that take a standard printer and fitting it with sublimation inks (thus leading to all sorts of problems), Sawgrass ™ is the only company that has a desktop printer actually designed and guaranteed for sublimation in the first place.

The design or image from the computer is printed onto the special release paper (called sublimation transfer paper), and from there is applied to the item which is then put into a heat transfer press.

There are a number of heat presses, for flat items, curved items, round items and even an attachment for printing shoes.

Sublimation transfers, have photographic quality, with bright vibrant colours.

Above as some images of the printer and presses for sublimation.

We have sublimation systems to suit all needs and budgets, from under R 10,000 to over R 80,000. We have a wide range of different presses and printer combinations, and you can even design your own custom configuration according to your needs.
