I just spent the entire morning tearing off platen tape... I did probably have it on there for over a month so maybe that's it? Any tricks or what is the timeline for replacement?
-
Heat. Flash them and they peel off easier. 8) 8) 8)
-
Ughhhhh that makes sense of course!!!
-
Sonny is right, get them warm, it comes off easier. Once a week, depending on how much you print is probably a good idea. I'm like you probably. Things get busy and you just gamble that they are ok for another run, another run another run. Until you have a huge chunk of glue/lint come off on some expensive 100% poly underarmor compression shirts then you realize, should have just kept the weekly replacement routine up. ;D

I just had this problem with my youth boards as they haven't seen action in a few months.

lol that is what exactly happened 2 weeks ago!

same problem here last week, tape been on my CH3 for 4 months! It was a bitch to get the glue off after the tape left it all on the pallet. TIP! Ink degrader! Works like a charm.

Or the lint gets so thick you have to increase the off contact... ;D
I have to say that even after months, transfer tape comes off clean and relatively easily.

Doesn't help you in your current situation, but -
we put one permanent layer of tape on the boards when we first get platens.
So, the bottom layer never has to be peeled off, only the subsequent layers.
Peeling old tape off of pallet rubber has to be one of the worst chores in the print business.

John, I used to do exactly what you are doing, but I think I may have left that first layer on too long at one point because the glue eventually locked onto the pallet rubber. Talk about HOURS to get that stuff off, and still didn't get it all. So If I were to do that again, I'd change that layer monthly just in case, lol. I replaced some pallet rubber and noticed two different textures to the sides of the rubber. One felt a little porous, the other slick. When I did the replacement, I put the slick side up and never have a problem peeling paper off. The pallets I have that obviously had the rubber installed with porous side up are always a big fat beeeeehooootch to peel paper off of.

But John is suggesting NEVER take off that initial layer. So locking to the rubber is expected and basically what he's after.

Understood, but what happened to me was peeling off the top layer started peeling off some paper from the first layer leaving a paper gluey mess that at that point, you have no choice but to clean the uneven surface. The tape I was using at the time was R-Tape. Since then I've been using Elite from Tubelite and never have issues.

Ah, good to know.
We've been using some of the "house brand" from us cutters and it's JUNK!
-
We tried the Newman pallet tape too, waaaaay sticky, the elite is decent price and seems to come off the boards no problem like the others we have used.
-
I'll have to apply for an account with tubelite, unless you know of another supplier.
"elite" and "tape" are way to generic of search terms.
-
Elite is their in-house brand for different items. I wonder if someone knows who may actually make that tape they re-label.

I sell 18" x 300' rolls for $48.15 ea.

Any good?
The stuff we have now shreds just trying to unroll it!
-
Man, I wish I could tell y'all the brand of tape I use, but I bought a big roll years ago from Graphic Solutions Group.
Since I'm pretty much a part time printer, I know tape stays on my pallets (formica covered, not rubber) for up to 6 months, probably longer and while the tape does come off in large pieces, I never had the horror stories you guys are talking about. Just last weekend I pulled the tape off and took maybe 2 minutes a pallet.
-
I think it's the rubber that makes it tricky.
-
From the notes I've been reading, think you are right. I had thought about changing out my platens for aluminum once and would have gone the rubber surface direction. Kind of glad I didn't make that move.
What was the benefit of rubber coatings supposed to be? Does a tape coating (sometimes 2 layers) take away any of the benefit?
-
same problem here last week, tape been on my CH3 for 4 months!
Do you ever print fleece on it? We have never been able to leave it on that long, sure would be nice though.
-
I think it's the rubber too. The first rubber platens I had came from Ryonet. Pealing the paper off could peal off parts of the rubber too. Even with heat applied. I got some replacement rubber when I left a platen under the flash too long. When the time came to change, the paper pealed off in almost one piece. Quite easily. I replaced them all with the new rubber and now I have no problems.

Sonny, I'd like to buy a roll of your stuff..PM me and i'll get ahold of you. Man I have no clue how you guys keep that stuff on for the periods you do...I'm changing pallets on both presses three times a week, usually before they get in to work...that way drier is hot an presses are clean and ready for production as soon as they walk in the door...and I never have problems pulling it off, course I use my vinyl guys tape mask not sure if theres a difference or not...

I used it before I went to work for Xenon. Flash it and it will peel off in one sheet.

only t-shirts, all the garbage material goes on the diamondback. it gets changed more often.
-
we have been going back and forth between performance shirts and regular gildans at least once or 2x a week... anytime we go from cotton to peformance fabric, we change the tape.
Sonny: haven't gotten a chance to check out the new tape I got from you yet, but i'll post a review when I do.
-
not sure if the glue is the same but i used to do signs and I'm pretty sure the backing paper for vinyl graphics are the same . When we had a delicate situation and had to pull the backer off we sprayed water on it and the glue would let go really easy?

We do that change quite often too, but I find the "fleece" on the platens holds the glue better and we have less problems with tech shirts releasing from the platen after the flash. You do get the odd thread or lint ball showing faintly through the print from the bump it creates on the platen.

Almost sounds like you're pulling the tape off when it loads up with lint?
Are ya? Or do you use a wet towel to wipe off the lint, lightly flash to dry and continue?
-
I have never had a problem getting the application tape off of my "blue team" platens, but other brand rubber top platens have caused major problems. If you can get a "low tack" grade tape it is more forgiving when it comes to changing.
-
Don't know if terminology for adhesives has changed, but when doing decals for helmets adhesives a whiles back they were once graded on tack, bond and shear(sp?). If this is still true the issue appears to be more related to the bonding attributes of the adhesive...of course to make matters easier there is always chemical interactions (as simple as the temperature of your platens) to consider that may play a roll. I.e., if heating the pallet does help remove the offending material it may well be that when it cools so does the bond.
-
Our problem with tape (not completely regarding in use with pallets), is shredding. This happens off the roll even. So that is probably related to the paper/backing.

Now, THAT, I have seen. But attributed it to my very slow use and the original roll's been around about 7 years.

My first ever post....
On my Vastex, I HATED putting platen tape on it. I went with the common advice of flashing and removing. Well, THAT didn't help. I would spend hours rubbing it off to point of blisters on my thumbs.
What I have found is that on rubber top platens, at least Vastex rubber tops, you want the tape to be cool. I will let it cool overnight. Come in in the morning and it peels right off!

Well, let me be the first to say...........
It's about time!! lol.
Welcome.
