FLUORESCENT INK BASE  -  8000IC /  FIB

Aron 8000IC/ARC ink bases are a unique combination of ultra-fine, high strength fluorescent pigment dispersed in a rheologically controlled vehicle system. This yields maximum color density and excellent printability.

Advantages of inks made out of these bases include highest color print density, excellent dot resolution and image sharpness, improved water resistance on the press to assist in trouble free printing.

 To produce finished ink from Aron 8000IC/ARC ink base it is necessary to add varnish/extenders, oils, waxes and driers.

Due to essentially fine-micron particle dispersion of 8000IC/ARC, it does not require further milling of varnishes, driers, oils. These all can be mixed in a simple blending equipment. To avoid air entrapment in the ink, it is advisable to pass the ink over an open three roll mill after blending.

Rosin modified phenolic resins or linseed alkyd resins, certain of vinyl toluene modified alkyd and polyurethane let down vehicles can help in attaining optimum setting characteristics. Always pretest the ink formulation for drying and adhesion on the stock to be printed.

A combination of magnesium, cerium, calcium and zirconium dries give good results in sheet fed offset inks made out of these ink bases. Addition of Cobalt drier will accelerate the drying, but will also darken the color and cause instability. Excess driers may cause reduction in the brightness of the fluorescent effect.

High boiling aliphatic ink oils / combinations of high boiling aromatic fre ink oil with medium boiling aromatic free ink oil are recommended as primary and secondary tack reducers. In addition to reducing tack this will help in maintaining of ink viscosity, improving press stability and enhance blanket release. Drying oils like tung, oiticica and linseed oil can also be used to reduce tack.

Small amounts of non-fluorescent color can be used effectively without significantly detracting from color brightness. Increase in color strength will usually compensate for any loss in brilliance. For example 5% red lake C flushed color added to 70 – 80 % of fluorescent orange ink base will result in a noticeably stronger ink without a significant change in the hue(or) brightness.

ARC have been formulated to resist water emulisification (water pick-up) characteristics. Additional anti-emulisification additives should not be necessary.
