InkMaster®, Formulation Master, and X-RiteColor Master use some terms that need to be understood in order to properly prepare your ink data. The following definitions should give you a better idea of what these terms are describing.
Light Ink – This is ink that can be used, as is, directly on a printing press. A “Light Ink” contains pigment, vehicle and solvent. This is also referred to in InkMaster as “100%” ink. Everything that is measured into InkMaster is done as a “Light Ink.”
Heavy Ink – This is ink that has everything in it that it needs to go to press except that it is high in viscosity or tack. A “Heavy Ink” contains pigment and vehicle. A “Heavy Ink” may or may not have solvent in it, but it still needs some amount of reducer to make it a “Light Ink.”
Concentrate – This is a non-ink or base that still needs some amount of vehicle to properly disperse the pigment and/or achieve the proper pigment:binder ratio. A “Concentrate” contains pigment only (this may be in the form of a dispersion, base, flush, etc.). A “Concentrate may or may not have vehicle in it, but it still needs some amount of vehicle to make it a “Heavy Ink.
Extender - This is press ready ink that contains no colorant.
