Sign Fail: What happened to this sign? Views & Opinions please.
Never seen this before and it’s doing everyone’s nut.
We didn’t do it (honest) it’s monomeric, but it’s at our smoking area.
It’s like the black ink has attached its self to the laminate and slid down. Just wondered if anyone has seen it before. Been driving us stir crazy for last two years [emoji30][emoji30][emoji23]

Does the text on the right side of the sign pull to the left (opposite to photo pulling to right)? If so I would say the black ink has somehow cured to the laminate and the underlying vinyl has shrunk at a greater rate to the laminate. Just a guess though Strange!
-
I think the other way round.
The black ink is as it should be, and the vinyl has shrunk creating the shadow effect. Looking at the edge of the board it looks like the laminate about 1" in from the edge.
-
Ah that could be it David. The shadow could be on the laminate although it looks on the sign…
P.s sorry if this is anyone’s sign.

I think its as it should be, you just havnt got your 3d glasses on

The clear has shrunk, taking some of the ink with it.
And water’s got in between vinyl and laminate
A cheap job turns expensive. -
Yes the laminate has shrunk. It looks like an indoor laminate used outside.

Even cheap vinyl wont shrink that much…
The problem is down to "Out-Gassing" of the ink!
The vinyl has been printed onto, then laminated pretty much right away.The out gassing of the solvent ink MUST go somewhere, but it is now trapped between the laminate and the printed base layer of vinyl. This has an adverse effect on the laminates adhesive, making it gummy and never able to actually cure/bond to the layer of ink.
the laminate/vinyl is same, its reacting to the solvent below making it very soft and stretchy. as the gasses expel, they create a push on the vinyl laminate. in turn the laminate never settles and is in effect moving on the surface creating this huge shift/shrinkage you see.
Once water, or air pockets behind the laminate, the push and distortion on the vinyl is increased much more.the black text will have went down as a 4 colour process making it the heaviest densest coverage of ink. The laminate appears to have picked-up a ghosting of the dark ink on the adhesive side, and due to the shift/shrinkage direction, it is giving it a shadow effect.
If you look at the black screw/cap fixing.
Look at how the vinyl has bunched around the black fixing. the laminate is bunched around the south west side of the fixing showing that the shrinkage pull is from south west towards north east direction.
With this in mind, look now at the black ghost shadow text, the shadow is implying the movement in the same direction.
"So to conclude Your Honor!!!
this sign maker is guilty of applying lamination without an ink out-gassing period!
His sentence will be embarrassment and slander by the public towards his inability to do his job correct, which i imagine will last throughout the life of this sign."$this->BBvideo_pass(‘$8’, ‘$4’, ‘$7’)

Well.. we’ve cleared that one up now. Who are we picking on next?

I guess the question would be then….
What is a reasonable out gassing time to leave from print to laminating?
-
haven’t the foggiest! 😆
Dependant on the application, standard is 24 hours but as much as 72 hours for vehicle wrapping which has been set by some wrap vinyl manufacturers. Latex inks also fall into a curing period of similar times.

Wow! 3 days ‘out gas’ for wrap on vehicles!
