DYE SUBLIMATION

The basic inkjet dye sublimation process uses a heat sensitive sub-limation dye, dissolved in a liquid, to print graphics and text onto special inkjet paper. This is called a dye sub transfer. The dye sub

transfer and a sublimatable item are then placed into a heat press.

When the heating cycle is completed, the image on the paper has been transferred to the item and has actually become a part of the surface. Run your finger across the surface of sublimation and you

will feel nothing.

The reason for this is that sublimation is always done on a polyester, polymer, or polymer coated item. At high temperatures, the solid dyes in the print converts into a gas without ever becoming a liquid. The high temperature also opens the pores of the polymer and al-lows the gas to enter. When the item is removed from the heat press, the temperature drops, the pores close and the gas reverts to a solid state. It has now become a part of the polymer. Done cor-rectly, it cannot be washed out or come off, unless the actual fibres

or coating is damaged.

This is why Inkjet sublimation can't be done on natural materials, like 100% cotton. Natural fibres and non-coated materials have no "pores" to open and so the dye just sits on top of the fabric. Heat

transfers are the best way to imprint cotton and cotton-blend fabrics.

99.9% of inkjet sublimation is done on white materials (substrates is the technical term). The reason for this is because the inks are actu-ally transparent, when sublimated, and need a background to show up. White is the ideal background because it does not clash with the

colours. Indeed, the white background actually enhances the colours.

This allows sublimators to print a wide gamut of vibrant, brilliant col-ours on multiple substrates. Some of the items include Soft-Link™ T-shirts (a cotton shirt, with a micro-weave of polyester on the out-side), coloured mesh ball caps, with a polyester front, mouse pads, jackets, beverage insulators, polyester calendars, clock faces, doll clothes, polyester patches, ceramic plates, mugs and tiles, FR plastic, coated MDF hard board (coasters, clipboards, etc.) and many other

items.

TASK 2: Copy and complete the brief I am going to design and make a Gizmo pouch for use with a gadget such as a mobile phone or iPod. I will design and print the graphics for the surface and then use Dye Sublimation to create my product……….(now mention things about the following: quality, costing, time).

HEALTH AND SAFETY (RECAP)

TASK 3: During this rotations lessons you will learn several safety rules when working in the workshop. Answer the following questions

Why is it important not to have liquid drinks near the computers?

Never touch the Dye Sublimation Machines. Why not/

Why is it important to wear an apron during practical lessons?

You should not run in the workshop. Why?

What should you do If you find something in the workshop which appears to be broken?
