oil on hp 5500 prints
wer have recently printed stuff on our hp 5500 uv printer, we hung the prints up over the weekend to dry and when we came in on the monday morning all the prints had an oily outling and where the prints were hung between two poles there was a oil pool laying in the botttom of the prints, has anyone else experienced this or know what could be causing it.

Hiya Darren,
Without seeing the prints, I would guess that there’s a couple of things possibly going wrong.
First may be that you’re using the wrong profile for the media which is causing the printer to lay down too much ink. If this is the situation, the ink would puddle on the media while it’s coming out of the printer. The fix here would be to use the right profiles for your set up, starting with your design software.
The other issue could be defectivematerial or that you’re using incompatible media for your ink. What happens here is the print may look fine when it comes out of the printer, but the ink isn’t penetrating the surface of the media. So, when you hung the prints to dry, the ink just ran down the surface. Contact your media supplier for a solution there.Checkers

Hi Brian
Cheers for the reply, the profile we are using is the correct one for the material (hp colourlucent uv), we have been printing on this material for 3 years and the inks we are using are original hp uv inks, we first thought that it was a roll of defective paper so we tried another roll and 2 more rolls after that with the same results, We have tried it on different profiles aswell but it still does it, the substance coming off the paper is very much like oil, it leaves an oily glow around the outside edge of the prints and over a couple of days pools where they are hung up, we have rang around some people and nobody seems to know what is causing the problem. 🙁
Cheers

Hmmm.
When you tried the other rolls of media, were they a different product, or the same product with a different lot number? If it’s the same material with the same lot number, you should expect the same troubling results.
If that’s not the problem, the only other thing I could come up with is somewhere along the line something got switched or changed. It’s time to play detective and figure out what has changed since the last time you ran the media. Did you recently refill the ink stations? Were there any spills or accidents near the printer, ink or media? Perhaps, the manufacturer changed their manufacturing process or screwed up (which is not uncommon). Maybe the inks were accidentially switched in the shop or maybe the profiles were accidentialy changed within your design software.
Sorry I can’t be more helpful. So, good luck!Checkers

That’s good news Darren and thanks for the update.
How did you finally determine that it was the media?Checkers
