Screen printers everywhere asked, "Frank, why don't you make one of your 'clean and simple' safe products for quick on-press clean ups and color changes?" "Why not, indeed?" said Frank, and now this water rinseable, on-press solvent is available to make your life less complicated. This is another "less is better" product. An ounce of Color Change should handle the ink on a standard sized textile screen. Availabe in Quart, Gallon, and 5 Gallon sizes.
