Screen Printing Info One: Type of Dyes

Plastisol the most common plastisol based print used in garment decoration. Good colour opacity onto dark garments, clear graphic detail, with as the name suggests, a more plasticized texture. This print can be made softer with special additives or heavier by adding extra layers of ink.

Water Based inks these penetrate the fabric more than the plastisol inks and create a much softer feel. Ideal for printing darker inks onto lighter coloured garments. Also useful for larger area prints where texture is important.

Discharge inks used to print lighter colours onto dark background fabrics, they work by removing the dye in the garment – this means they leave a much softer texture. They are less graphic in nature than plastisol inks, and exact colours are difficult to control, but especially good for distressed and vintage prints.

Foil - is what you would imagine. A glue is printed onto the fabric and then foils applied for a mirror finish. Due to the gold or silver foil used, minimum quantity of 100 applies.

Glitter/Shimmer silver flakes are suspended in a plastisol ink to create this sparkle effect. Usually available in gold or silver but can be mixed to make most colours.

Metallic similar to glitter, but smaller particles suspended in the ink. 

Expanding ink (puff) an additive to plastisol inks which raises the print off the garment, creating a 3D feel.

Caviar beads again a glue is printed in the shape of the design, to which small plastic beads are then applied – works well with solid block areas creating an interesting tactile surface. Minimum quantity of 100 applies.

Four colour processartwork is created using dots (CMYK) which combine to create the full spectrum of colours needed for photographic prints – this means an infinite number of colours can be printed using only 4 screens, making the set-up costs viable. The inks are required to blend and are more translucent, meaning a compromise with vibrancy of colour.

Gloss - a clear base laid over plastisol inks to create a shiny finish.

Nylobond a special ink additive for printing onto technical or waterproof fabrics.

Mirrored Silver Another solvent based ink but you can almost see your face in it.
