De-Lamination issue: HP Latex 360, Premium Photo Paper, and hot lam

Do you laminate right out of the printer? I have some issues with de-lam on wrap films. Avery Dennison advises to put gas latex prints for at least 6 hours and more if possible.

 

We have the same issue. Wasn't a problem with the 260 but with the 360, the only thing we encapsulate is the HP poster paper or an uncoated paper. I assumed it was due to the optimizer and the photo papers..

 

Someone from avery actually said that? We have had issues with delam but everyone Ive ever talked to about it just plays dumb.

 

Its a problem with all the latex inks, there is a wax in it to stop scratching, slow the laminating down to 0.6, and some heat helps.

 

not an outgassing issue, not an optimizer issue. those "canned" profiles are great, and work as designed.
reason being the prints are dry once they come out of the printer (tech may have just been mistaken, being used to telling people to outgas solvents in solvent printers) and optimizers go below the ink but your laminate makes contact with the top of the ink.

+1 its gotta be an incompatibility issue with the laminate, or just needs more heat/pressure.
which laminator and laminate are you using specifically?

 

not sure why you are laminating a premium paper. seems like a waste of money to me...the premium paper is probably micro-porous...that's why the paper does not like thermal laminates.

 

last issue could be if prints have too much saturation on them....some people thing they need 400% density for a good black....some pics would help

 

Just a thought here, would it be worth using the cheaper media for prints you’re laminating and the premium paper for the ones you’re not?
