Haze on inside of glass

[MarkyW]

I saw this haze on the inside of the glass against the solid black background of a framed printed photo.

Here's a picture of part of the image that is framed.

I opened the frame and found more than just the mottled haze shown above. I also found a copy of the image in haze on the glass, shown below.

Now, I've seen this kind of thing before on OLD pictures I have reframed, and have read posts about what people think might cause this kind of thing.

The thing is - I JUST FRAMED THIS YESTERDAY - less than 24 hours ago. This is 1 of 2 samples for an artist who printed this out themselves on their wide format printer. This one is framed to the edge, no mat, against the glass. (I know, but that's what he wanted to do with both of them) He agreed to try the other with a mat, although the size of the print still allows the print to touch the glass since it is not mounted down solid. The prints were brought in 1 week ago. Even if he printed them right before he brought them down, I would think that they would be totally dry by now.

Could it still be outgassing? (if that is what causes this) The finished frame was leaned against the wall face in, so it didn't even have light shining on it. I don't know if there is anything I can do to keep this from happening. It would probably need a triple mat (or more) to keep the image from touching the glass, or to be mounted, either of which adds to the cost, which he wanted to keep down as much as possible. If that would even stop the problem, because I think I remember seeing haze images like this on old prints that were matted and weren't touching the glass.

Any ideas? The only thing I could think is if he does the pictures with a mottled grey or whatever background instead of the solid black background. (black is always a problem) The haze would still be there, you just wouldn't really see it.

Outgassing from the ink, let it dry completely.

How long should they dry before they stop outgassing? I don't do printing or know the particulars involved, and he said he was new to printing, so I don't know if he will know.

Just talked to the person for a second time. He said he printed them a week before he brought them to me and I've had them for a week. 2 weeks isn't enough time to totally dry? He also said he called the printer company and they were asking him what the temperature of the glass was and other stuff like that. What???

If its heat safe, you could run it in the press at a pretty low heat to dry and vacuum it of moisture.

I've had outgassing on 2 week old printed inkjets, being used for split plain clear / UV clear samples.

It has usually outgassed on the plain glass side, where the inkjet part is exposed inside the mat, and not the UV glass side.
This happens a few times during a week or two process of getting the sample ready (fading effect differences).

Your was only a day glazed, so maybe the just needed a while longer.
Who knows about what every type of ink needs, one of the home (or even commercially) printed inkjet dilemmas for framers.

I suggest getting the client in for a look, advise you will redo, but maybe leave it another week for more drying before reassemble.
Get him to take it home, and if it needs cleaning in another couple of months, let him know if you'll redo it for him foc, or charge a small nominal fee.
(Glaze it for easy redo, if it doesn't haze again, tell him to bring it back in for sealing properly.)

It looks like Jesus to me!!! It's a sign !!!

The characteristics of an ink-jet print are determined by three elements: 1) the ink-set, 2) the paper, 3) the printing machine. If these three elements are carefully matched, the results can be wonderful. If not, who knows? Henry Wilhelm's Institute has test data available on all kinds of ink-set/paper/printer combinations. Informed print-makers know all about the recommendations and the cautions. For those who buy ink-sets and paper by price, it's a crapshoot.

Inks are chemical concoctions, and some of them are more reactive than others, especially if the paper contains reactive additives or the printer disperses the droplets of ink incorrectly.

It may be that the ink-set/paper/printer combination used to make those prints is will result in offgassing for unpredictable amount of time, no matter how long the prints are allowed to dry before framing.
