Window Cling with spotty ink

[HannahB-AG]

I am running static window cling on an HP L2600 Large Format printer. On the lead edge of prints, up to a foot into the print, we are experiencing a printing issue where there seems to be pinpricks/spots in the ink that don't print. The areas aren't terribly noticable on the backing but when adhered to a window the light comes through and renders the cling a poor quality. It's a really heavy ink coverage - full flood of rich black ink - at 16passes. In order to keep the print head from scraping the material, I have the vacuum up to nearly as high as it goes to keep the backing down. I am using edge holders and curing at high temp (if I lower the temp, the ink does not dry). The issue seems to be mainly on the lead edges. I've tried adding about 3" of blank black material to the lead edge, but it does sometimes exceed that area. Looking to see what might be causing this and if anyone else has run into the problem? We have a huge event coming up where we will be running a lot of this cling and I need to get it resolved before the majority of the artwork starts rolling in.

Thank you for joining HP Forums.

It's a pleasure assisting you in finding answers to your technical queries.

I see that you are facing a print quality issue with the printer.

To provide you with an accurate solution, I'll need a few more details:

Could you please help me with the exact model name or the product number of the printer?

Are you facing the same issue while making a copy? ( if available )

Did you try printing from a different application?

Keep me posted.

Have a great day!

Cheers:)
