I've switched to a Hp570 and have noticed that the ink is creating a de-lamination problem when hot laminating. The paper is a polypropylene synthetic paper and the laminate is 43 micron glossy laminate. I don't have any problems with normal cellulose based paper and the same hp570 ink, but as the HP570 is incapable of printing on cellulose based paper I have no choice but to go to a synthetic paper.
The synthetic paper is designed to be laminated but it seems like the ink is creating a waxy layer.
I'm using 110% color 10 pass with 35% optimizer at 100 degrees C
I've tried increasing/decreasing the temp, increasing/decreasing optimizer, but it looks like the ink is problem. Just need to know what paper works on these problematic machines?
Every SAV substrate should work on the HP printer. See below some recommendations to fix the issue:
• Review the SAV film specifications and overlaminate specifications to find recommended combinations.
• Some media suppliers and dealers provide a compatibility matrix where these recommendations are also made. Review it when available.
• Surfaces where overlaminated printed film will be applied need to be cleaned to remove surface contaminants.
• Give overlaminated printed films time to bond before manipulating them: 24h for regular jobs (direct application).
• 20⁰C-60% RH environment.
I hope this helps.
