Hello @Blackwell-Print

From the picture that you have post it seem it is an issue with plasticizer migration on the substrate.

I suggest you 2 things:

  • Clean the surface of the substarte with isopropyl alcohol
  • Return the roll to the Media Vendor

Ok, thanks, I'll try and print on another vinyl stock that we have and see if the problem remains.

Cheers,

Hi all we have an HP Latex 330 installed just over a year ago, and it's great.

However just recently the prints on our Vinal Self Adhesive Gloss stock have been coming out a bit strange. Not sure if it's the subsrate itself or a substrate settings issue. All the print heads have been renewed too. See photos for examples of print quality. This was particularly bad this morning when the room was quite cold and the print material was also cold. Would this cause this issue to occur?

Cheers guys,

Hello, I'm having the issue with my HP Latex 365. The media I'm using is Orajet 3164 XG (from Orafol). I've printed several rolls of that media with no problems, but the last 2 rolls I have that issue. I've used Orafol ICC and HP Media Support ICC and I have the same problem. I tested another media from Orafol and is working fine. We escalated the issue to Orafol and the answer was that is a problem with the HP Latex 365, and because of that in the HP500, HP added a cleaning devide to avoid that result. Is this true? Orajet 3164 XG is a very demanded media in my market.

Could you please confirm is this is because HP Latex 365 inks?
