Moving on from heat transfer papers for a while, we had some left over heat transfer inks in the studio, i haven't used them much, and i'm pretty sure they're past their 'use by' date but i'm so glad i've borrowed them so that i could make this video. They are so easy to use... literally the same as any other ink, although these are a particular dye that transfers on to synthetic fabrics when activated by heat.
Again they are usually used with a heat transfer press but can easily be printed with an iron too. Like I said i'm sure they are very old by now as the colours aren't as strong as they should be, but depending on the fabric used, the colours do vary in saturation, which can be beneficial is you want pale colours.
Back at the studio we usually would use Dysperse dyes that originally come in a powder form, we then weigh out certain amounts to create recipes for colours. These inks from Colourist.info are premixed. They are fantastic, i delivered a workshop a year ago for group of children and it's a great way to get them painting and they absolutely loved seeing their designs then transferred onto fabric!... of course i was the adult who used the heat press for them.
Here's video 4 showing examples of using the inks...
