Lamination knowledge needed

make a 'sled' table that you run the substrate on into the laminator

 

Sometimes, instead of using the laminator to get it started like you did, I put about 4-6" down by hand. Just faster for me to do.

i've done 50% pinch, as well, but I always hated how long it took... i enjoy just running the panel through once and be done with it.

...therefore, if i'm going edge to edge, i like the graphic up on the table and use a tape-hinge by wrappping the tape around the backside of the panel and then just peel the backing far enough back so that you can hold it, have your laminator preset to your thickness/pressure beforehand, and just shove it through.

i'll even oversize my graphic so that i can hang 1/32" of the graphic off the hinge side (which wraps around the edge with the hinge-tape), just to make sure that i don't leave any "bare" material after all is said and done.

 

Here's how I do it. I usually make my prints slightly bigger than the substrate. So a 4x4 would be printed at 4.25x4.25. Place the print on the substrate and centre it. Use 2 spring loaded clamps to hold the print in place (make sure the clamps have padding so they don't ruin/scratch the print). I put 1 clamp in the centre and the other towards the back. Now take the print and fold it back over itself. Peel back the release liner about 2" and fold it over or cut it off. Place the print back into position and stick it to the substrate. Now remove the clamps and but the substrate up to the rollers and feed it in about 1 - 1.5". Fold the print back over the laminator. Grab and hold the release liner and remove it as the substrate goes through the rollers. Trim off access vinyl and voila, you've mounted your print with ease. Man, I hope this makes sense.

I usually just use my thumb. Note that using this process can sometimes cause bubbles right where the laminator takes over. you can avoid this by pulling back on the vinyl just a bit. I like to squeeze both hands around the vinyl and the roller and pull back just enough to release any air that might be trapped.

 

Never used a laminator for that, seems to me that if you go through the trouble of laying down 6 inches of it why not just push the BS across the rest of it and its done?

 

put it on wet by hand.

 

I think your initial way is the best way to do it. The time it takes to lay down the first couple of inches by hand is a lot greater than the time it takes to flip the print and run through twice. On larger prints it aligns better than starting on one edge and watching it travel 1/2" by the time it gets to the other edge of an 8' panel. Just don't do it on foam core or you'll leave a dent.

 

p.s. congrats for figuring out your initial method on your own... i never thought to do it this way until i saw it done at the ISA show last year. Someone actually sells an applicator that operates like a laminator (guess it can laminate too!), but with a hand-crank and a foot pedal that controls the pressure.

the hand-crank (and an additional roller) also allowed him to operate it backwards just as quickly, so instead of flipping the panel he just lifted the backing off the otherside of the graphic and shot it back through the other direction.
