Window Graphics Failed- Any Ideas as to Why?

[Court]

According to our notes, this was printed on Drytac Polar Blockout for side A. Side B was printed on Drytac Clear mirrored, then sandwiched onto the block out after outgassing. Block out was laminated with Briteline satin Wrapcast laminate. Installed to an interior window that is exterior facing. Applied dry.

The last photo is what it looked like when first applied. Would love any insight as to why this is failing

Did you use a laminator to 'make the sandwich' or did you do that by hand?

We used our roller table

Those two adhesives are definitely working against each other. Drytac clear is a monomeric vinyl vs the brightline is cast. The glass, blockout film, clear vinyl and overlaminate are expanding and shrinking at different rates, causing it to separate like that. Especially black on the inside of a window. It can get hot.
We typically print blockout film two sided and then add a double sided adhesive like the General Formulations 118.
You could try to print the clear and laminate with the briteline and then apply to the blockout vinyl and that might be better but it might have the same issue. I'd forgo the laminate all together. You don't really need it since it's on the inside of the window and not facing the sun.

I agree with the above comments about the adhesive working against each other and also them being two different kinds of vinyl. You have to be very careful when you're using different adhesives and also a cast and a calendared material. Bad things happen quickly. Also you could have too many layers like mentioned above as well I wouldn't use any laminate either.

My hunch is that it is too much solvent black ink. Big solid blocks like that in the heat and a three part sandwich is a lot to ask. I'd not bother with the laminating film, either. That is a lot of things stuck together trying to make it in the heat.
