7600 Series Direct Print Plastisol Inks consists of non-phthalate, high performance colors, formulated for ultra high speed wet-on-wet automatic printing. These inks offer superior performance through fast production speeds, good opacity, and wide range of popular colors.
Well suited for fine detail and halftone printing using finer mesh counts.
The 7600 Series inks will spot dry, with a very low after flash tack. Dwell time is dependent on the spot dryer used. In some cases, you may have to lower the heat of the spot cure unit because too much heat may actually make the ink tacky. When you spot dry, you are only partially fusing or gelling the surface of the ink. The ink should be just dry to the touch, with no lift-off, but not totally fused. Total fusing of any flashed color may cause inter-coat adhesion problems with the inks printed on top of the flashed ink. Final fusing or curing should occur in the dryer.
Use an underbase print when printing 7600 Series inks onto dark fabrics. Use 711, 7014, 7031 or 7041 white as an underbase ink. To achieve a softer hand and faster production speeds, print underbase ink through finer mesh counts (230 to 305 t/in or 90 to 120 t/cm mesh).
Adding too much reducer or other additives to the 7600 Series inks may cause curing / fusing or increased dye migration problems.
Excessive squeegee pressure will drive the 7600 Series inks through the fabric being printed. Adjust squeegee pressure, angle and off-contact to insure proper shear and lay down of printed ink.
Test dryer temperatures and wash test printed product before and during a production run.
