Rotometal’s rotoINK UV range is compatible with all current narrow web flexo presses. Our inks have been designed to work seamlessly with both, conventional open Flexo units, and chambered doctor blade systems. They has a special formula that adjusts to different speeds and pressures, and prevents bubbles and foam from forming.
With rotoINK UV, you can print faster, smoother, and sharper.
Thoroughly evaluated through rigorous testing, the rotoINK UV has substantiated its compatibility with an array of self-adhesive materials, encompassing:
Type of ink | Anilox volume cm3/ m2 |
Process colours | 2.5 - 4 |
Solid colours | 5 - 10 |
Printing speed* | 70-160 m/min |
* The printing speed is contingent upon factors such as the quantity and characteristics of lamps, as well as the type of etc. Based on tests held internally. Many variables have the potential to impact the ultimate printed outcome. Therefore, we strongly advise verifying the ink’s precise performance before commencing full-fledged commercial production runs.
Thoroughly evaluated through rigorous testing, the rotoINK UV has substantiated its compatibility with an array of self-adhesive materials, encompassing:
For optimal performance in adhering to most synthetic materials, the attainment of a surface energy ranging from 38 to 42 dyne/cm is pivotal. The integration of corona treatment in-line is strongly recommended to achieve the most favorable outcomes.
Given the inherent disparities among material variants from distinct suppliers, it is advised to align with any specific recommendations furnished by your supplier. Furthermore, we advocate for the diligent practice of conducting preliminary tests on new materials before embarking on new design endeavors.
