General description
GFT4600 is appropriate for paper and cardboard substrates and also water-receptive polymer films and provides a unique combination of high-speed printability, fast drying, and conductivity in an easy-to-use ink system. GFT4600 can also be printed on plastic films bearing a water-receptive primer
Caution
GFT4600 is a fast drying ink that will dry to the touch between 150-300 feet per minute using standard dryers found on flexographic presses. Maximum conductivity can be achieved with further drying, inline or offline, using infrared (IR) dryers, high capacity forced hot air ovens and/or heated mandrels. Optimum drying conditions should be established for particular equipment used by the customer.
GFT4600 is supplied as ready-for-use ink. Soft sediment may occur over time so thorough mixing prior to use is necessary. The ink may be diluted with water up to 3%, however sheet resistivity will increase slightly. Dilute with caution!
The below details are only a guide, and the final choice of flexo printing specifications may depend on substrate and web speed. To achieve maximum coverage, high volume anilox rolls are recommended (80-120 lpi with 14-22 BCM).
Continuous anilox rotation is required throughout the print run to avoid ink drying on flexo plate and anilox roll. GFT4600 should not be allowed to dry completely on printing equipment. Prompt cleaning with water is highly recommended. Anilox rolls should be also cleaned using a sonicating bath after each print run.
