Sun Chemical introduced an innovative new range of durable UV varnishes for enhancing the label resistance of HP Indigo digitally printed pressure-sensitive labels for products such as personal care, household, chemical, beverage, and pharma applications.
The new range of varnishes was specifically formulated to provide adhesion to HP Indigo ElectroInk and has been designed to provide high levels of mechanical durability on HP Indigo printed labels. Furthermore, the solution delivers mechanical, chemical, water and thermal resistance withstanding vigorous bottle-to-bottle scuffing test, making the range the ideal choice for ensuring high durability, and in some instances offering a cost-effective and benefit from sustainability advantages alternative to cumbersome lamination processes. The new varnishes promote cross-linking with the HP Indigo ElectroInk and the primer layer to deliver improved physical properties and high durability in challenging applications.
The new set of varnishes are a press-ready solution and do not require the addition of any press-side additives for ease of use. Ensuring consistent durable labels time after time, the range can be printed using standard UV coating equipment.
The solution has been tested across some of the most popular label substrates including PP White, PP Clear and Metalized Substrates, ensuring a consistent level of performance.
Available as part of the SunEvo™ Protect LEP HD range of protective varnishes for HP Indigo, the range highlights another example of the high level of cooperation between HP Indigo and Sun Chemical.
Two new products are available as part of the set: EV-LU028 GLOSS and EV-LU029 MATTE. The range is available to be ordered immediately. Commercial production has started in Europe with other regions following shortly.
“We have conducted field trials with the HP Indigo community across many countries for a few months and the response has been phenomenal,” said Marcos Valdezate, Sun Chemical Global Business Development Manager for SunEvo™ Coatings for Digital. “Customers have challenged the durability of these varnishes and have seen how long-lasting they are. This is another great example of how coating innovation can expand the range of applications for digital printers and actively expand their offering.”
“Through innovative varnishes, adhesives and coatings, DIC and Sun Chemical are enabling HP Indigo customers to pursue cutting edge solutions,” said Itai Shifriss, HP Indigo Global Supplies Business Director. “We appreciate our collaboration with DIC and Sun Chemical and look forward to advancing our customers growth together.”
