Pretty sure you are using the 831 inks in that printer. That is a known issue with that Avery viny/lam combo and those inks. If you switch to the Avery 6460 laminate you will eliminate that problem. It’s a little more cost, but you will also be able to offer a horizontal warranty because it’s a non PVC laminate. Negotiate with your suppliers. They can get you special pricing if you use a lot of it and the price difference can be very minimal.
