IJ 380 issues with bubbles and rippling
Hi,
Recently did a job for a company, using IJ380 for the first time. We printed Monday, laminated Wednesday and wrapped Friday, when coming to the wrap though, we found it a nightmare to use, bubbles appearing after squeegee-Ing an areas, ripples when using the squeegee, and the controltac feature did not work at all! We were wrapping in temperatures of 18 degrees.
Just wondered if anyone had similar problems with this stuff and how they corrected it. Was it not out gassed enough? Thanks.

Plenty of people on the forum have used it & I have never read anything but good reviews about it, don’t print myself so only fitted it if supplied to me by a trade printer & never had a problem.
How were the graphics kept prior to laminating? If left rolled up or on the take up roller then out gassing might be a problem. Did you use the matched laminate for the material? Where did you fit it? Inside or outside? If outside was it in direct sunlight?
Was the bubbling & rippling in areas of high ink content?More info you can give then the better the answers you receive are likely to be.

We used the matched laminate and fitting was done inside, with creases and air bubbles being all over, as the whole if the vinyl was covered with heavy ink. The vinyl was kept on the roll after printing before laminating. Thanks

I think your problem is that you kept it in a roll before laminating.
Someone in this forum, I cant remember who, explained the following better than I can repeat it, but:
The solvents in the ink are heavier than air, so the printed material should be hung up vertically, so they can fall off the surface, and there should be a free movement of air all over while this is happening.Simon

Thanks Simon, will bear that in mind on the next job. Will test out what difference it makes to hang it out off the roll. I don’t want to give ip in this vinyl just yet.

Craig, take a bit of time to read some of the threads on out gassing, if the print is left rolled up then the solvents can’t escape so although you had left it 2 days the solvents hadn’t all evaporated. Heavier the ink load the more solvent will be trapped, people have come up with all sorts of ideas on how to hang up their prints to dry :lol1: :lol1:

I don’t really see how you can hang up prints if its a wrap and you have a roll of 20 metres or so. You can only really unfurl it a bit on the core and preferably raise it off the ground on the end protectors.

what Printer and Ink did you use on this IJ380?

quote Jon Marshall:I don’t really see how you can hang up prints if its a wrap and you have a roll of 20 metres or so. You can only really unfurl it a bit on the core and preferably raise it off the ground on the end protectors.I have to agree with John, I’m no expert on wrapping but have printed about a 100mtrs of the grafiwrap material lately. After printing unroll it as loosley as possible and stand it on upside down plastic core holders.
I have a bout 16 of these glued together, this makes a good platform for gassing prints. I know many on here do the same -
Hi Craig it may be a gassing issue but also control tac is pressure sensitive
so you have to apply a lot of pressure. The fact that you say the control tac
isn’t working points to a gassing issue I think. The best way to gas prints is
to hang them for 72 hours ideally, a lot of people just stand the prints on the
ground but this is no good they need to be loosely un wound at at lease 6 inches
of the ground so the air can flow throught the prints.This is a common problem and its something me and Robert try to drum into people
on the UKSG wrap course.Hope this helps and good luck with it
