I seem to have periodical ghosting when sublimenting. I tape my transfers to the t-shirts and I use teflon pillows to reduce the suction and allthough that helps, it has not eliminated the problem. I never once had this problem with my old 15X15 clamshell press, but now with my upgraded 16X20 swingaway by Geo Knight I do get this problem. It is to the point where I am pushing the Ash colored shirts because It masks any imperfections. I think this is possibly the problem because when I release the and raise the platen I am not pulling it up perfectly straight which was never a concern with the Clamshell.
Does anyone know if there is any trick or gadget you can use to ensure that the platon does not start to swing just ever so slightly whil raising of your print? I'ts getting to be sweatshirt season and every misprint is going to cost me triple.

Thanks,
Cory

I have the wilflex spraywhich I use for mousepads koozies and other items but it's kind of a pain using in my office. I use the Tee-Squareit to align my shirts which means once everything is aligned I slide the design under the tool and tape it. It's a pretty cool tool and I would hate to have to abanden it. Using Willflex would not allow me to slide the transfer under The Tee-Squareit so I use the tape instead. Also, If you put the transfer down crooked with the spray you can't really nudge it straight.

Any word on a attachment or gadget for the press that would keep the press perfectly straight (not allowing platen to swing right) until it was raised up to the top or at least a an inch or so.

Applying oppisite pressure does do the trick but when I am doing a bunch of prints sometimes I don't press left and I can actually see my platen shift right

I just got a small ghost after using tape on all 4 sides and I let up real slow. Tomorrow I am going to build a little spray booth so that I can go back to using the Willflex. My reason for abandoning the spray was because I work out of my office on the second floor of my house and it is a pain going down to the garage to spray each transfer when you are doing even a small shirt run. I picked up a cardboard box which I am going to convert to a spray booth and see if I can prep the tranfers in my office without having to go through the whole house.

Has anyone else made a makeshift spray booth to accomidate spraying in your house?

I am going to eliminate the teflon sheet from the bottom platon. That is the one difference I made when switching to the new press. I used the teflon so that if any ink penetrated through the shirt, I could just wipe the teflon. On my old 15X15 press I used to tape regular oversized paper over the bottom pad. The paper was probably around 100lb. That always did the trick but I had to change the paper often. What is the best way to protect the bottom if you don't use teflon?

I don't believe it is the pressure because I use a teflon pillow inbetween the shirt so I don't get the press lines.

I don't get ant blowout with shirts, I don't use very much pressure the teflon is just in case. Tiles are usually the worst for me as far as blowing through the paper.

OK maybe I am not getting ghosting, could it be some sort of shift? I ask because last night I did some tests. I did extra spray on the transfer paper. It was just a test so I sprayed it real good. This sucker wasn't going to move. In fact I had to peel it off it was so adhered. my first test was perfect. I did two more tests and my last test had a shadow again. I know the image did not move.
I also waited several minutes before peeling to eliminate that variable.

I did not have this problem with my smaller 15X15 clamshell. Not once no matter how reckless I was. Now I have to be super careful while doing shirts and it is still a crap shoot. I am to the point where I will not do any orders except for grey short sleeve t-shirts. That way if it ghosts to the point that I do not want to sell it I haven't lost the cost of the more expensive clothing.

I am pre-pressing the shirt for 10 seconds and I am pro spraying. The transfer is not moving. I just went back and looked at the used Transfer sheets and you can totally see the double image on the transfer sheet as well. Does this point to anything.

I left the Teflon fitted cover on the bottom platon but covered it with butcher paper to eliminate the slippery effect. Should I remove it completely? Is the teflon somehow sending the heat back up causing this double image? I just don't get it

Confused,

My press is spotless. I am very anal about that. Plus, It's a perfect double image not blow out. I did a dozen tees last night that had a baseball swish logo that included a small spot with there # on it. One of the shirts that I know did not move had a perfect drop shadowon the number. It actually looked good so I let it slide, but it wasn't intentional. This double image happens when I use my 1280 with Artanium inks or from my 4880 with Sublijet. I have used different profiles, Powerdrivers and the like. It's definately something in the setup of the press. I still have not tried removing the teflon on the bottom platon since nobody seemed to think that was an issue and I really like the protection it gives my rubber pad but I think I will try that tonight. That does seem to be the one thing that is different from my smaller press.

Could it be a temperature problem? Too hot maybe? Should I lower the temp from 400 to 390 or something?

The most frustrting thing is that this is the DK 16X20 press which is very popular and although everyone has been very helpful, I can't believe I am the only one that gets this problem. It's not the Press either because I actually had this replaced with another of the same model. My last one had a digital defect but before it was replaced I had the same ghosting problem.

You know, I tried everything and did not eliminate the ghosting problem on a regular basis.

Last week I got an order for doing sublimation on a bunch of expensive Hockey Jerseys. My business is doing pretty good so I decided to buy another smaller press. I purchased the 15X15 Mighty press. I always missed my smaller press for it's portability so if nothing else I would have a press to do some events.

Well, The mighty press works great, No matter how reckless I am at opening or closing the press the print always comes out crisp and clean edges for a perfect print.

The Geo Knight 16X20 swing is just too finicky for doing sublimation on shirts. It works great on tiles and other hard substrates, It ican't just be my press because I exchanged it once before thinking something in the mechanism was out of line.

I don't recommend the Geo Knight 16x20 for sublimation, but I will probably need to buy another 16X20 press within a year.

What should I get??

I ended up buying a 15X15 Mighty press which has never given me a ghost image yet. This led me to call DK directly and thank them for my GIANT PAPER WEIGHT. They did finally get down to thee problem and it works fine now. According to them the DK20S creates a significant amount of vaacum compared to other presses so you have to just crack the press open slightly, wait one second and then open very slowly the rest of the way. Also They had me bolt my removable platen to the press (Making it a pain to switch). So now I have an extra press for backup.

Allthough I solved the problem, it is amazing that my new clamshell press doesnt' ghost no matter how I press and The DK20s has to be babied.

I occasionally have someone help on big orders and I will only put them on the clamshell. I can't afford having anyone transfer on the DK20S.

I guess this is only a problem with Sublimation

Jen, don't give up on sublimation, give the clamshell a try when working with apparel. It solved all my ghosting issues. Your Geo Knight swingaway is still good for all other transfers, vinyl, inkjet, plastisol etc.

I still own my Geo Knight 16X20 press and use it the most. But when it comes to sublimating on shirts, I use my Mighty Press Clamshell
