700 Series Direct Print Plastisol Inks are engineered with a selection of HP (High Pigment) colors for dark fabrics, standard colors for light fabrics, and a softhand clear (720) that can be mixed with ink to help soften the feel or hand of the print. Well suited for automated equipment although excellent results can be achieved in almost any printing operation.
For softer feeling prints on light colored fabrics, use 20% to 25% by volume of 720 Softhand Clear Base. Reducing the viscosity of the ink using 1110 Curable Reducer and printing through finer mesh counts can also greatly improve the softness (hand) of the finished print.
The 700 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 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 700 Series inks onto dark fabrics or fabrics containing polyester. 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 700 Series inks may cause problems with curing/fusing or increased dye migration.
Test dryer temperatures and wash test printed product before and during a production run.
