After research and talking to others who use heat presses every day, I decided to go with Geo Knight over Stahls Hotronix. I wanted a 16"x20" press and it came down to the DK20S and the HX20F IQ. Reading on forums I got the feeling that the Hotronix presses were more expensive than they should be and saw a lot of frustrated users, frustrated over the quality of the press and the customer service from the company. The Geo Knight on the other hand had the opposite feedback, its built like a brick crap house and service from Geo Knight is excellent, which I can attest to now as well.

There is just one thing I do not like about the press. And that is when feeding or "threading" shirts onto the "table", unless its size Large or bigger, its going to stretch the shirt. That is because the base of the table is dead center below the center of the table. When you are pressing the front of the shirt, the back of the shirt can only travel as far as the front of the table mount, again in the center. And because of that, it stretches the shirt. Stretching the shirt will cause weird dimples in those far corners, toward the back of the press. And if its a size Small or smaller, its stretching the bottom/waist of the shirt too.

The IQ press from Hotronix also mounts in the center, but the mount is on an L shaped arm allowing that same bottom of the shirt to travel much further back and in turn, results in no stretching at all.

Does anyone else have this issue on their Geo Knight DK20S press? Have you found a workaround for this?

I know I can just lay the shirt on the table, both the front and back layer, but then I get press marks on both the front and the back. I want to thread these on with no stretching. Heat press marks are a whole other topic.

Teflon pillow inside the shirt?

Im talking about loading a shirt onto the "pallet" of the press. Heat press MFGs call the pallets "tables". I do have a teflon wrap on the top heater part of the press, and one on the table as well (overkill maybe but nothing ever sticks), but I do not put anything in the shirt itself, well other than the cushion of the table. Does that make sense?

Here is a link to a video of the loading of a shirt. This is what I am talking about. They must have used a size L or XL for this demonstration. Would love to see them show us a size S and load it, cuz it will stretch. Scroll to the 2:20 mark for the loading or "threading" of the shirt.

Could you use one of their smaller "tables" to swap out for the smaller shirts to eliminate the "stretching"?

DKP-1012TBL or DKP-1416TBL

Looks like they offer a number of optional "tables" on their web site that are compatible with the DK20S

What Frog says, use a teflon pillow inside the smaller shirts if having issues. Also get a teflon sheet for the bottom platen, this way the shirt slides on way more easily.

I have a MEM Double heat press (2 of them) with a pedal. We have youth platens for it, but have never used them. We have had no issues.

I considered that, but that doesn't help when I am pressing a 20" long print on a size Small. I am considering ordering a new 16"x20" pallet and modifying it.

I have teflon wraps on top and bottom, so im covered. And yes that def helps slide garments on and off, but does not help with the stretching. I guess I will look into the pillow, but that sounds like it adds a lot of time to each press, having to insert and pull out for every shirt.

Sounds like the MEM press has a better pallet mounting setup, that doesn't stretch the tees. Wish Geo Knight would address this because it is such a simple design fix.

Your pillow suggestion gave me an idea. I have never tried the pillows before, but they sound interesting. Then I thought, what if I just lay the pillow down first, and then the shirt laid flat on top, that way I do not have to mess with putting the pillow in the shirt at all. So basically just leaving the pillow as the cushion for the bottom pallet, essentially replacing the foam rubber that comes attached to the pallet.

Then I got to thinking, well since I already have the pallet wrapped in one of those teflon wraps, why not put the pillow under that wrap, allowing it to trap the pillow between the pallet and the wrap. Which would hold the pillow in place. Again essentially just replacing the pallet top with the pillow. This has me pretty excited! I am easily entertained I know.

Then I thought, since I already have the telfon wrap for the pallet, why even buy a teflon wrapped pillow just to trap it. Why not just source a sheet of high temp foam and trap it under there. I could buy a sheet that hangs off the edges of the stock pallet by a 1/2" on all sides, which would eliminate any hard edges of the pallet. Time to start sourcing high temp foam!

Thoughts on this?

Although the "permanent" pillow underneath would help to equalize pressure due to uneven thickness of seams and such, it isn't nearly as effective in reducing the pressure marks they cause.

Does the pillow inside the shirt reduce that? Or is there another method?

It does seem the press marks from from the shape of the pallet, and not the heating panel. I need to look at my press again, but the pallet has more rounded corners compared to the heat panel itself, and that is what I am seeing on the shirts, the more rounded corners. So that tells me they are coming from the pallet and not the panel.

We press a ton of DTF, sometimes just laying the shirt on and pressing say the front and back together doesn't work as well for us. So threading the shirt on the platen or pillow, makes it the correct heat.

But there are different factors in every shop.

I like this. It's a Nomex pad. I used it when I was doing die sub on flat items. It's stiffer then a pillow. but still has give so you don't get the hard edge.
You do want to put a teflon sheet on when you have a print facing it as it will pick up some of the fibers.
