Plastisol inks are most commonly used in screen printing because they are not ‘air-dry’ inks and when producing longer print runs they will not dry up on the screen. There is more choice when choosing your Plastisol inks, more colours and also additives that can be added to your
Plastisol ink to produce special effects such as puffer/expanding raised effect, suede effect, lycra additive, glitters and also metallic’s.
Plastisol inks MUST be fully heat cured before washing to avoid the print coming off in the wash. Plastisol inks wrap around the fibres in the fabric, sitting on top of the fabric producing a more ‘dense’ appearance and have a rubbery feel to them. You can change the appearance and feel of the Plastisol ink by using an extender base or a super smooth base so as it feels and looks like the water based ink or sublimation ink.
Plastisol inks cannot be ironed directly over, due to the plasticiser in the ink.
Plastisol inks must be cured at a temperature of 150degreesC or more For more information about curing Plastisol inks, please see ‘Curing your print’.

We have also put together a set of guidelines for using additives with Plastisol ink,
The waterbased ink is like a dye that changes the colour of the fabric and has a sublimation appearance.
Waterbased inks have a softer feel as the ink dyes the fabric as opposed to ‘sitting on top’ of the fibres, has an almost non-existent feel to it.
Waterbased inks are widely used in schools and colleges and also on babies clothing as are economical. One important factor you must remember, if you are printing an all-over print on to a garment that needs to be ironed such as a cotton shirt then a water based ink would be more suitable as you can iron over the print.
When printing breast size logos 9cm x 9xm approx, waterbased or Plastisol can be used but you cannot iron directly over a Plastisol print as it will re-melt the Plastisol and smudge. Water based ink can be printed onto dark colours with high opaque white ink, however the other standard colours will need a white underbase printed down first. When you are printing with Waterbased inks don’t let the ink dry in the screens it can block the stencil.
Only you will know what sort of design work, images large/small you will be printing and designing, this can determine which one of the two to use.
