laminate tinting prints yellow

[tiredcreations]

I only notice on beige or ivory. After laminating with Hexis lam. it tints it yellow, and enough that it's unacceptable.

Has anyone experienced this?

a search yielded this: http://www.signs101.com/forums/showthread.php?t=46650&highlight=tint
but I can't imagine it being a print problem as it looks fine before lamination. just in case (Flexi, production manager, Roland SC-500, Roland EcoSol Max).


I'm going to get some different lam but I don't want to run into the same problem if this is common with certain brands.

In my experience, lam has either a yellow or blue tinge to it. It's the nature of the beast. Maybe someone else here has something different to say/add.

hmmm never had a issue here with any laminates turning prints colors. I have used the general formulations intermediate laminate (grimco's briteline). 3M 8509 and oracal 210.

I notice it with 3M 8519. I allways assumed the yellow tint was from a UV blocking additive similar to the yellow shooting glasses?

With the proper profile and intended lighting your colors should be correct.

laminate ALWAYS proves a yellow tint on prints. if you are doing any kind of proofing, always proof of the the laminated print.

I'm pretty sure the tint is in the adhesive.

It's usually not enough to be an issue and it's hardly noticeable by most but it can be a pain. Try reducing the yellow in your print until you hit the desired colour. I know, easier said than done.

Alright, thanks guys.

I did start laminating before proofing when I first noticed this, but on this last job the customer just wanted an "ivory" background - no specific color to match, just ivory. I got lazy and told myself the laminate can't make that much of a difference. I was wrong.

You won't notice it much until you print on greys and flesh tones...

look, the real issue with this thread is understanding the output of your printer/s, and the technology that you employ. not to mention the variables that are present.

with that comes the knowledge of educating the client based on your experience of what you know your equipment is capable of.

hitting TRUE colors based on the clients need in a digital enviro is so far fetched.

we can get close, but upon perfection we are so far away.

its all about expectations and how they are set.

you should always profile a laminated print... i even have glossy and matte versions of my profiles/color charts for every media i stock.

Some professional help with laminates changing digital print colors

I have seen this phenomenon (laminate affecting final color of a digital print) on occasion, and found that it usually occurs on mid-tone grays and skin tones as someone else pointed out.

Personally, I could not haver predicted, or adjusted the printing process to address this issue, but found someone else has.

For reference, I have attached a great article published in Digital Graphics , June 2008 and written Rich Adams of Ryerson University.

It explains the how and why of addresssing color shift due to laminate effects.
