According to some members here, outgassing is a myth. I don't prescribe to that though. I let our Roland prints sit until the next day. If it's a RUSH, I'll print on the Epson S80600 - it dries much faster, and you can laminate with in a few hours (they say 6).
I laminated and installed as soon 4-6 hours but that is printing slow with max passes and a heat lamp on as its going from roll to roll and installed on a flat surface but with a print for a wrap I wait till the next day to laminate and install with unrolling the take up reel some overnight, I have a roland VG2 with tr2inks
I am using a Roland XR-640 with the Max 2 inks. But I am looking at the Epson 80600 but waiting to see if Epson releases the 90600. The Roland had been a work horse and I haven't really had any problems with it. Just wish we could get the Max 3 inks here in the US.
It also depends on your ink coverage, and how much ink your laying down. If there is very little coverage, and/or use a lower quality setting, you could laminate after a few hours without any problems. Now, if you're printing something obnoxious like 100, 100, 100, 100 - black, you better let it sit for a good while. At least 24 hours.
Ink coverage and where your graphic will live can and will play a part of this theory. Manufacturers put out a time to protect themselves from scrutiny if a failure does happen. If you are double or triple striking film or translucent vinyl you may want to allow more time. But 95% of the time no issue
I find the adhesive is gummier/stickier if you don't allow any outgas time. Honestly we hang a lot of wall murals that haven't been outgassed w/out incident. Vehicles are in a more severe environment, but I've also installed many wraps that were off ecp solvent printers and had little outgassing time as well.
