There is a misconception about HP latex printing, In as much as the lamination process.
latex printer suppliers, sales reps, over-sell the machines based on the ink drying time. However, that is because HP themselves got this wrong. Keep in mind HP are specialists in making the machines, not how a huge list of media reacts to their machines printing on them or how they perform further along the line, once applied.
Yes, you can laminate vinyl after it comes out of the machine but you should leave it as long as possible before doing so. Let’s just call this period the “settling period”.
When you run vinyl through a latex printer the vinyl is being taken up to 110+ degrees. It is being jetted with ink chemicals, fans blowing on it. the vinyl is expanding and contracting, it’s being tugged on by the take-up system, tight wound again on the core, and more… it needs time to relax, settle and return to its cool temperature before moving to the next stage.
You then laminate the latex prints, but again, you want to leave the laminated prints as long as possible. let’s just call this period the “bonding period”.
Similar applies to the above. hot or cold laminated, it is pulled through and around rollers under tension. it is being bonded onto a new “ink-covered surface”.
The laminate now requires time to “bond onto this ink”.
take a bit of vinyl and stick it to a van.
now pick it back off. it comes off easy!
Try doing the same after a day sitting in the sun. it’s stuck solid!
This is because the adhesive has been given time to reach its optimal bond and performs much better. So the same applies when you laminate onto an ink saturated surface! and by that I mean…
The ink and vinyl must “settle” and once laminated, the laminate must be allowed to “bond”.
this all doesn’t really come to light when the laminated prints are fitted to a flat sign surface. but it does when your next step is to apply the same two layers of vinyl and ink are quickly bridged across a deep recess of a vehicle and heat and over-stretched into the recess and stuck there, and “EXPECTED” to say there for good?
Keep in mind, all vinyl types and brands react and perform differently. So It is NOT just about ink type and the manufacturing process.
there is a list of boxes that must be ticked when manufacturing wraps and installing them and above are just a few things you must keep in mind.
HP are aware of issues and have made modifications and improvements in the newest range of printers to help. Only time will tell…
I have heard good reports about the recent Epson machines, but with new machines and more so, ink types. How well they will perform in the wrapping world is anyone guess. Epson, their distributors or sales reps will not be able to give you an educated guess any better than HP would have 10 years ago. Because they simply do not know until it is used in real-world environments.
