3 Star Certification Achieved Through Grade Development for HP Indigo Digital Presses

GoalHelp a specialty paper mill to expand into a new market.

<h6>Customer Challenge</h6> <p>A North American specialty paper mill was looking for a way to expand into the fast growing HP Indigo Digital Press paper market.&nbsp;</p> <p>Paper for this specific market requires the use of special additives designed to improve indigo press adhesion and runnability. Additionally, paper performance has to be certified by a HP Indigo Digital Press approved evaluator. Approval ratings are given as 1 star, 2 star or 3 star performance with 3 star being the most difficult and of the highest value.</p> <h6>Recommended Solution</h6> <p>Solenis recommended using imPress ID-115 surface sizing agent at six active pounds per ton, added along with the mill&rsquo;s standard size press solution. The paper was assessed by an evaluator from Rochester Institute of Technology (RIT) to confirm Indigo certification.</p> <h6>Results Achieved</h6> <p>The results exceeded expectations. Paper machine runnability was excellent and both broke re-use and press performance such as offset were acceptable.&nbsp;</p> <p>At RIT, the paper achieved the coveted 3 star rating, with near perfect results in all categories including adhesion, blanket compatibility, and press runnability. The customer achieved 98% - 100% adhesion including black and photo mode. Following this trial, the mill has received 3 star certification on the rest of their grade structure including all basis weights.</p> <p><img style="max-width: 100%; width: auto; height: auto;" src="/link/3b36e2e9e2a849e6b292a24922f244a7.aspx" alt="" width="975" height="520" /></p> <p>&nbsp;</p>
