We are doing so many screen printed transfers these days. We prefer to coat them with the adhesive powder, but i cannot figure out a quick way of doing them, aside from hand coating every sheet. Right now i'm looking at a rack of about 150 sheets.
What is the most effecient way to coat these bad boys before they go in the dryer?

We do very little, so we hand powder, but I've wondered about the Heat Transfer inks, as supposedly you don't need the powder with them, would be better, especially if you are running so many?

I remember reading something about an adhesive that you add to the ink before printing.

Buy the right ink and no powder is needed...... we do hundreds of them every week and have not used any kind of powder or crystals since we started doing them 20 years ago. Make sure you have the right ink, paper and cure........ no problems. My girl can do 500 an hour and everyone of them will stick to a shirt like it is supposed too. Not all inks require the same amount of time in the tunnel so be sure to check and make sure you do not over cure...... get rid of that crap and start with some real mass production.

what is the ideal ink? These transfers we just printed are using union maxopaque Red.
Typically we are using a russel gray for neck labels though, and we buy it from River City.

We only use the powder when going on tricky substrates, IE polyester foam trucker hats.
We mix it into the ink. Works a charm. I can't seem to shake and bake without
making a huge mess or ruining the sheet.

We use the one stroke white for bases on transfers with Rutland colors on top - one stroke transfer ink
Curing properly based on the manufacture specs is the most important part. We still use the glue since we can't always turn down the dryer, but I printed 2500 2 color transfers on auto with this as the base and ran them through the dryer like a charm.
What I would like to find is a transfer paper that doesn't curl up so much under the flash, maybe something that doesn't need to be preshrunk for multi color transfers? Anyone have a lead on that? We are using the Arjo Wiggins T75 and X75 currently.

When we used to do transfers, we bought a wide shallow bin and filled it with powder. After printing, we would place the transfer ink down into the powder and pat it down. Lift, and shake off, and done. If I recall, we got the bin from the lawn/lumber area of Home Depot.

You might try slightly heavier T105 from Arjo Wiggins, to reduce curling

Here is our "Magic" formula for no powder transfers...... One Stroke 380 Series ink...Ultra strip 3000 hot split paper or Trans 105 Cold peel paper..... Paper available at many sources but we get ours from Ace Transfer. It's that simple!

Has anyone tried One Strokes ELT Zip inks?
They pretty much use the same T105 paper and recommend the sugar but I wonder if they would fly without adhesive for private label applications. I like that they claim a 330˚F cure, that means no adjusting the dryer and they can run with Ts potentially.
