20 1 4 O ctO b e r Printwear | 87 set up a job to print and spend money on discharge ink, and it still doesn't work. However, the idea of discharge inks is wonder- ful. The objective is to print softer images, and you can do this without incurring the risks of discharge inks. Let's say you're printing a black shirt. First, print an underbase of super-opaque water-based ink, which requires a dual-cure emulsion. Pull the squeegee only once. This creates a gray, not white, image, and that's okay. You must change the color strength of the image area, so a plastisol ink in the next screen produces the opacity. Start with a 230 mesh, and under certain conditions, later print plastisol with a 305 mesh. The soft hand is far superior to print-flash-print or printing through a coarse mesh, like 110, to achieve an opaque image. Water-based inks are not opaque like plastisol inks, but when dried with a heater fan positioned over a passing platen, you can't feel the ink. RogeR Jennings, R Jennings Mfg. Co. How do I keep water-based inks from drying in my screens? Keep the image area flooded. Leaving the screen flooded during production keeps the image area wet to prevent ink from drying in the screen. Set the flood bar to 1/32" off the screen. This results Add texture to lettering by draw- ing your own shapes and colorizing them in different percentages of the same color. this limits the number of colors used, yet gives the illusion of multi- color.
