Polypropylene on HP Latex

[TP-Raptor]

Hello all,

Our next purchase is a flatbed, and we like the look of the HP Latex. Regional location so the user replacable parts is very handy.

We do a lot of thinner polypropylene on 0.6mm and 0.8mm, and double sided.
But the thinner polyprop can't handle the curing heat of the latex, and the material deforms and curls and creates headstrikes.

We like the latex as the ink adhesion is great, its smooth and basically becomes part of the substrate, and cuts great.
I know UV is improving, but I don't like the way ink sits ontop, and chips with cutting.

Does anyone have any tips or tricks with latex and thin polypropylene?

Or can they suggest another machine or technology that handles this better.

Thanks,

The Latex R530 cures ink at far lower cure temperatures than the 300/ 500 Series, and even somewhat lower temperatures than the 6/7/800 Series does. Curing temperatures can be driven as low as around 70C (158F) on the R530 platform due to the larger and more robust cure unit, and the dynamic 16-zone Intelligent Vacuum System.

In addition, there is an available accessory called the Lateral Pinch Roller kit which can be useful with particularly temperature-sensitive boards. I would suggest that you reach out to your reseller or HP directly to request physical sample prints on the media(s) that you are concerned about.
