    Hi guys,

    Just grabbed a roll of Ri-Jet 50 printable & Ri-Jet 30 lam for a temp wrap on my van.
    Having some serious issues with printing on it, my first thoughts were heat settings but after trying lower and lower temps each run I’m starting to think the roll may be contaminated. Pics below, I’m about 3m in now and still the same

    I'm assuming you've printed on this material in the past without an issue.

    Have you tried a test print on an area that you cleaned super well? I don't run wide format, but sometimes I get rolls of vinyl where my foils on my Edge don't adhere and you get a look like this and it turns out that there is a residue on the material. So I clean it good with alcohol and test it.

    Not on Ri-Jet 50 no, however the Arlon, 3M, Avery and Metamark wrap films I’ve used in the past have all been fine with similar this set up.
    I’ll give cleaning it before it goes through a try now but that’s going to be a pain since the print is for a full wrap

    Since you haven't used this before, I would ask if your ink is compatible with the material because it looks like it's not. It looks like it's not drying properly and it sitting on top of the vinyl.

    It’s definitely compatible with eco solvent ink.
    It’s looking like contamination. Gave a couple of meters a good alcohol wipe before it went through and printed flawlessly, apart from a few small patches that I missed.
    Going to be a long old process is this one

    Looks like it could be an old roll and that the plasticers have leeched out of the media? Just a guess. Try cleaning an area with alcohol and printing on it to see if it makes a difference. Either way I would try to return it and get a new roll.

    Okay... this may sound condescending... BUT, it looks exactly like what happens when you print on the wrong side of porous media. Was this roll from a company that winds the media in the opposite direction?

    Yeah... it was a long shot. No offense intended, for sure. I’ve seen it done when the media was from a different vendor and rolled opposite from the norm. It was a big “oops” and a good laugh.
