For DCS printers and inks, a single pass of clear ink printed over a color image at 2880 DPI (separation curve 4) will improve the abrasion resistance 2X to 3X and will give resistance to Windex and other types of ammonia based glass cleaners. Two passes of clear ink over a color image will give IPA resistance when wiped with a cloth soaked in IPA. Soaking the image with IPA for 30-60 seconds will still cause the clear ink to soften and expose the color image below.
Please note, all substrates should be tested for image receptivity and durability with final acceptance and suitability determined by customer.
