solvent prints degassing – advice on how long to leave
Hi all my first of many posts 🙂
solvent degassing on vinyl prints, how long do you guys and girls give it before laminating, some say 12 hrs some say longer, also do you just leave them on the roll or lay them on a table ?
just printed some wrapping films (arlon 6000 xrp) left it 24 hrs before laminating, applied to the vehicle,
WOW it stuck like **** to a blanket 🙁 it was like chewing gum, very sticky, was told it needs to be left longer to degass.
just printed another job left this 4 days on a washing line (home made) pict will be supplied soon, fitting this next week So ill let everyone know, how it was.thanks Gary

Try doing a search on the forum, been discussed quite a few times. Sorry can’t offer any advice myself as don’t own a printer.

Would your vinyl supplier not be the best person to ask, surely they have guidelines for the material they supply

i think they guess sometimes, i was told between 12 – 24 hrs or along as you can, and it also depends on how much coverage / % of ink is printed.

Hi Gary,
I no longer use solvent printers as have now moved to latex. I do have had experience with solvent though.
I would say a minimum of 24 hours for outgassing, however its not good enough to simply take the roll off the printer and leave for 24 hours. I would recommend leaving the prints hung up to dry if at all possible. If not, unwind the roll loosly and put it on top of a milk crete. Believe it or not the solvents fall to the bottom of the prints and if rested on the floor the gases cannot escape. Even better if you can get a fan pushing air through the roll for a while to blow the solvents out.
Arlon DPF can be very tacky if fitted in a warm environment regardless of outgassing so make sure your in a suitably cool area for fitting.
Hope it helps.

I buy mine in in and usually leave ’em at least 72 hours before laminating (I don’t do much printing so leave them hanging flopped over the top of a couple of doors and move around a few times during that period) Ideally as Chris mentions having a fan arrangement would be an advantage . . . .

We use some prints within a few hours but blast them from the back with a heat gun. Don’t do it from the front as you may cause a slight skin as with paint.
Never had a problem this way. They are much dryer than leaving up to hang at room temperature. -
theres a 3M video on YouTube where they do some extensive tests and apparently, leaving it flat on a bench is the best way.
This is all academic in my opinion if you are doing wraps as there is simply no way to lay out 20 + metres of prints on a roll. And if you do they will get covered in dust over the 24-48 hours.
