Laminate Peeling - IJ680CR, Ink Related?

[Station51Graphics]

Quick breakdown: we print on 3m IJ680CR (sometimes IJ180cv3) with an Epson ecosolvent printer, laminate with the 8418G laminate, cut with a Graphtec FC series machine, and pre mask with SCPS-2tape.

We have seen repeated instances of the laminate peeling off edges of the vinyl a day after installing (squeegee, heat, squeegee is our installer’s proces).
on our latest job, I noticed the laminate is peeling from the edges of areas that did not have ink, but did not peel from the areas that had been printed on.

Has anyone observed a similar occurrence that would be able to offer a suggestion?

Is it peeling on all sides? Or just a few?

I'd blame the laminate and upgrade to one recommended for the 680, looks like 8518/19 or 8914. Significantly higher cost, but that 680 is already super high so...

The lam peels on all sides. 8418G is listed by 3m as a compatible laminate for the 680cr, so am certainly frustrated at the failure.

Well I'll be, it is. I was mistakenly going off Feller's recommendations, but it's listed in the product compatibility matrix.
All the same, moving forward you know not to use it, I'd be wary of putting any laminate on a product when the cost difference is that great, I guess that's a good rule of thumb to go by.

Did you let your prints out gas? Oh sorry I see they are on the edge where there is no ink.

 

[Station51Graphics]

Perhaps.
Yes, the vinyl off gassed.

I've seen 8518 peel with ease off of IJ680CR, but never separate autonomously. I've never tried this lam before and now it makes me a bit skittish to try.
