If it was printed on a HP latex series... heat setting was too low on the print. I love our HP printers, but I have to remember to raise the heat level about 12-19 degrees for solid colors or full color pictures, otherwise we get that slick print feel.

Is it only on the black areas?

What is the CMYK value you guys use on a latex printer for black? I've switched to a 60/40/40/100 in hopes of having less of an issue on the HP latex for black.

With the latex delamination is mostly due to ink density and not allowing the water to fully evaporate before laminating. This was a none issue on the older ones because they didn't have the optimizer and scratch resistance additive. We have learn to profile to the lowest pass settings to prevent too much ink or if higher passes are required we have to let it sit for awhile after printing.

I'm running eco-solv but out of respect for your knowledge I always take note of the technical observations you make for future reference. I thought the OP stated that he let the prints dry for a few days before laminating.

Are saying even that isn't long enough if the proper pass settings aren't selected?

The various salespeople pushing a new latex machine on us always use the argument that you don't need to wait as long to laminate latex as you do solvent.

You can generally laminate right away with latex. You just need the right settings... Whether it's higher heat, higher passes, or intwrpass delay to make sure it sits under the heater long enough.

Some media's still feel a little oily right after printing... Such as 680 reflective. That we generally let sit awhile before laminating... But we've laminated a few right away and haven't had an issue yet.

If all conditions are working perfectly, the heater should be evaporating all the water before it gets out of the machine and you shouldn't need to wait.

In the real world, your shop could be more humid, colder due to winter so your heater isn't as effective... Or your settings not nailed down perfectly. 99% of the time laminating right away is fine in most cases though.

You technically don't have to wait at all, but there used to be obscure docs from HP that mentioned waiting 48hrs before laminating prints with solid colors and densities above 120. We have found in our testing that 6 pass provides vibrant enough colors for most clients, those with tricky colors we can typically hit them with 8 pass. Above 10 pass is where we have always had issues with laminates.

Many years in the Production Business
As a manager of many service techs on all the digital inkjet printers I have knowledge of exactly what causes this on Newer HP printers which use one heater instead of the older models which use 2.
I also sold hundreds of HP's, Rolands, Seiko/Oki's, Mimakis for high volume wrap companies so I have a lot of info for you.
I will discuss this but only privately so you can give me a call or text me at 631-520-3074

Bruce, this is a place to share information. Both of your posts have dangled a carrot in front of users but have offered no valuable input.
Either discuss the issue or not. No secret "deals".
 
It looks like the ink was not properly set before laminating.
Let us know which printer this was produced on.
I have sold and done training on all the inkjet printers for over 20 years.
I am guessing maybe it's a new HP latex?
I have had several of my customers develop this with the HPs and we have a solution.

So what's the solution? This is a place to share ideas and information, so share it.

Please, please, please: when you want help, please put all of the info in the post so we can help you easier/faster.
Important info like printer/rip/profile aren't in 99% of all posts here requesting help on this site.
