The 'sticky' or 'tacky' feel a Plastisol print has after being flash dried or gelled.
The final layer of white printed onto a Plastisol transfer when high opacity is required.
A Plastisol system that can be printed without any further additives while still maintaining its durability, light fastness, adhesion and curing properties - even when it is classified as an additive or auxiliary. Also known as Curable Plastisol.
The appearance that a printed image has enlarged or spread beyond the original printed area. Similar in appearance to the effect of fountain pen ink on blotting paper. Also know as Wicking or Haloing.
The paste-like deposit that accumulates on the print side of the screen - caused by the wet ink deposit from preceding colours in the print sequence that have not been gelled.
The ability of a printed image, once cured, to be stretched and return to its original form without any damage to the ink surface.
An apparent washout of a printed image as a result of the small fibres of the fabric protruding through the ink film after the first wash - giving the print a faded or hairy appearance.
The application of Plastisol transfers on to a garment, by means of a heat press. There are three important factors in this process:- heat, pressure and duration.
Once heat is applied to Plastisol the polymers begin to swell and absorb plasticizer. At the critical point (160º) it melts and forms a continuous film ensuring optimal fastness properties. Also known as Curing.
GLOSS VALUE The amount of 'shine' a printed image has, once cured.
HAND (HANDLE) How the printed image feels to the touch, once gelled, e.g. a thick deposit of ink will feel hard and rough, whereas a thinner layer will feel softer and therefore smoother.
INK FILM The layer of ink left on the fabric after printing.
INK FLOW The rheology or 'movement' properties of an ink system while being printed.
LIGHTFASTNESS The degree to which the ink can maintain its colour and integrity with prolonged exposure to UV light.
MATT Refers to the microscopic unevenness of the ink film surface which reduces it's reflectivity or gloss value and enhances the depth of colour.
MATT DOWN The ability to hold down the small surface fibres of the fabric resulting in a smooth printed surface, as well as the ability to maintain this property after the first wash.
MOIRé The undesirable, distinctive pattern that occurs in halftone printing, caused by the dots in the artwork positives not aligning with the open area between the mesh strands of the screen.
OPTICALLY BRIGHT A white that appears 'whiter that white' due to the slight emission in the blue spectrum.
OVERPRINT A second print on top of another print or ink film.
PASTELIZATION A reduction in colour intensity due to the introduction of white or reducing agent.
PICK-UP When ink on a printed image is lifted off by the following screen. This is usually caused by partial gelling of the ink film prior to printing the next colour.
PRINTABILITY The ability to print clear, crisp prints through a variety of mesh counts.
RETARD To slow down the gelling process, particularly when still on the printing press.
SG Specific Gravity. The ratio of weight versus the volume of a product. (kilogram's versus litres)
SHINE Refers to the microscopic evenness of the ink film surface which causes reflection of light, resulting in a higher gloss value and lighter colour.
SUBLIMATION Movement of fugitive or residual dyestuff in the fabric into the printed image on the application of heat.
SUBSTRATE The surface of fabric onto which an image is to be printed.
TACK VALUE The degree of 'stickiness' of a printed image after flashing or gelling.
UNDERBASE The first print onto which all other colours are overprinted.
VISCOSITY Thickness value or the 'resistance' felt when mixing a Plastisol.
