Does anyone have a source for this in the US?
-
We used to get it from NW Graphic but it doesn't look like they carry it on the site anymore. Kind of wished we had explored it more, it really speeds up application on the heat press.
-
What is this clear paper you speak of? ???
-
Just as it sounds. Transparent enough to position the transfer very accurately and quickly. Prints fairly well and we never had an issue curing it either.
-
Someone posted about an overseas source a while back, not sure about US. I ran across it a while back, but can't remember where. It was pricey...

So, one wouldn't have to trim as accurately, as well as making it much easier to dodge seams and such that may otherwise get in the way.
Right?

It's called PET - release/heat transfer film.. Although most would point to it's transparent attributes, It's main feature is it's stable cahracter in the production environment- No contracting and expanding like pulp from a tree..

Yessir Frog.
Also yes on the stability, anything helps in that department.

Is it good up to 260F or so?

I too would love to know of a domestic source.
Starchild, do you know of anyone domestically?

Domineight from this forum gave me these details
Casey@jbscreenprinting.com
Chinese girl, she will look after you. Install whatsapp on your phone as she's easier to get a hold of. She's basically a sales bot for a company called "kenteer new material and science". You can google them and see a little of what they do.
The product you want is "1185B" in 640x480mm sheet size. 100um weight.
Still isn't US Source, but could be helpful, although I emailed and never got a response, didn't try WhatsApp.
Forget about printing transfers the way you are. Sure it gets it done but it's inefficient and obviously a high reject count.
Correct, flatbed press, pre shrink the sheets first then flash down the dryer on a faster belt speed after printing each colour. Final cure belt speed/temp should be the same as your initial pre shrink pass down the dryer.
The media is PET, or silicone coated polyethylene. Very stable.
As for a dryer, I've used a small vastex econored with good results, and have actually just purchased a two chamber Lil red X2 also from vastex, specifically for this system.
Adhesive, best results are with Wilflex transfer printable adhesive and if you use crystals, also only the Wilflex variety. They'll have one weight of crystal so you can't go wrong.
I have a Thieme 4 poster press so production is very fast, but also I have an atma clamshell. Both very good modern presses. You could get away with an old American cameo, I have one of these too,a tempo actually, basically a large cameo withheld benefit of air pressure for the squeegee carriage.
1185b at 100um weight is the best media. It takes plastisol, waterbased, also solvent.
I attached a photo of his prints on it as well.
If anyone has a US source let me know as I want it!

Group buy? I'm in for a few thousand sheets.

Good idea, or I am reaching out to rcscreenshop.com to see if they want to source and become a distributor.
All comes down to price, would be hard to go from Arjo Wiggins T75 at ~10 cents a sheet or less, to something way more expensive unless it made the process just that much easier and better.
If it comes from China direct though it can't be that much more though!
-
i'd be in for a 10k at least
-
We run arjo wiggins T-120 or whatever the top shelf one is and I would be quintuple that for stability for multicolor.
RC is our Rutland and Matsui supplier, basically everything wb/dc/hsa for us and Christine actually reached out regarding a paper recommendation for plasti cold peel transfers. It's weird that nobody east of Ohio stocks the best paper for this, we still order ours from OH. Anyways, I should have suggested this product.
I'm in for any collaboration on getting a load of it over here and in everyone's shop.

In Europe it is

Maybe they have reseller in US
In fact they may have in the US

Depending on the price I could see us getting 5 or 10k sheets, assuming dimensions are around 13x19.
-
I see this on their website, no flashing between colors?

Unless you are doing sim process prints of some kind on the transfer, you'll still need to flash/gel between colors on any transfer paper unless you want a blurry mess with crap opacity. The kind of paper doesnt matter, it's still paper.
-
Here is a link to US producer/supplier:

Have no experience with their film, but like their US3000 paper

And of course, that's what I thought too. But, the claim is there; I can't see how it would work without flashing. Still, we'll try anyway...

Unless the coating on the film, and the way it receives the ink makes all of the difference
-
I imagine "inter-color heating" is referring to using a hot box to keep the paper temp stable after each gel.
-
There's a few different varieties. The code I gave in 100mic is the most stable safe economical variation. Gives a nice flat matt finish.
It also has the best hold so your transfers are nice and safely stored and can take a bit of knocking around before any ink is chipped or scratched.
I use Arjow Papers too. Not even close to the same stability.
No need for hotbox or anything extraordinary.
Pre shrink and print.
For what it's worth, I can run A2 sheets at 400 pieces per hour through my 4 post Thieme with the vastex Lil red X2 on the back. That's the equivalent of 800 A3's per hour.
I don't believe there's much more of an efficient system for such a simple and cheap setup. The reason I don't use a conventional rotary auto is because it's not really an efficient system, and you don't have the print control of a regular graphic press.
Comparing the two different types of screenprinting is chalk and cheese. The control of all print aspects of a graphic press is akin to a space shuttle when trying to print the same thing on a regular textile auto which in comparison is a clay wheeled roller skate. Even the newest textile auto with bells and whistles doesn't compare.
You could do it of course, but you're not getting the best result. It's simply the wrong tool.
Regarding 1185B from the source I've given. It's a nice safe good product. One I've used for years to terrific effect with plastisol. It's very easy and safe.
I've taken many wrong turns, trialled a BUNCH of different product. The product I offered is the best I've found for plastisol transfers. Using the system I use.
When I say wrong turns I'm talking about freighting 50+ Kg of adhesive with dangerous goods rating across the Pacific only to throw it all away because humidity destroyed it when the seasons changed. ::)
Or airfreighting product that wasn't up to scratch, not consistent in manufacture, or I was just plain old lied to in hunting the holy grail of transfer substrate.
By trade I'm a graphic screenprinter firstly. Did my time printing labels and signage, graphic overlays for the electronics industry, corflute signs and cardboard packaging with semi auto, 3/4, and full auto presses. That's my background, that's my trade. The textile component was always a side gig although I've been involved in it close to full time for 20 years.
As far as slapping a sheet on the pallet, hitting the sheet, flashing and printing again. Yep, you can do it, but I wouldn't. I just see that as going down the wrong track with the product, you may as well just use paper.
There is a different source that I didn't offer, because it's a more difficult product to use although the possibilities it opens up are incredible.
It reads like a few are keen to try the product. My advice would be for you guys to syndy up for a couple thousand sheets airfreighted in. Get it guillotined in half and share the sheets out to see how it works for you.
If you're having trouble getting a hold of Casey, I'll get in touch and see if I can have her post here. She's a good sharp girl but limited as she's simply sales. She's not the one to ask regarding anything technical regarding the product.
Unless you speak Mandarin, you're on your own like I have been over the last 10 years in working this stuff out.
In this post and the snippet of an email I've sent, an entire foolproof system is there.
1185B 100um PET transfer sheet.
Wilflex adhesive crystals - rack it out to let the static discharge before flicking excess powder off.
Wilflex printable adhesive. Print through 43T for best results. I've used 59S also with no problem.
The only other advice really, is forget all your conventional textile screenprint knowledge as it barely applies. To print transfers properly go the graphic printing route using a nice creamy easy to print straight out the pot plastisol. There's no substitute for peel or vacuum.
Edit*
Just realised Casey had sent me a link last time we had contact.

All the details there. Just remember 1185B, 100Um, 640X480mm.
You're welcome to get caught up on the other stuff they sell. I wouldn't though. You just want that one single product.
