When added in 3-5% increments by weight to any colour in the Excalibur 500PF or 533PF Series of inks, 105 Low Tack Additive will help reduce the amount of pick-up on bottoms of screens as well as help ink clean from the screen image. Also, this product when added to any Excalibur white ink will greatly reduce after-flash tack of an underbase white enabling any overprint colour to be printed immediately without cooling off. Reducing the pick-up on screen bottoms greatly increases profits by reducing press stoppages and reducing after-flash tack in underbase whites not only speeds production but also eliminates a cool down station on automatic presses.
