Okay I'm new at this t shirt game. I did some polyester shirts for a friend of mine for there racing team using thermoflex, but in the process of pressing the shirts the platen has left a square on the shirt. I reduces the heat to try and prevent this happening but it still occurred. Is this normal and just a side effect of using polyester shirts or have I seriously stuffed up? Does anyone have any idea if there is any way I can deal with the marks.

See if it washes out. Could be press marks and it could be scorch marks depending on how bad.

Hopefully just showing the area where the moisture was removed from the garment - will probably come out when washed. I have heard of people even spraying water on it to remove the mark

one thing i have learned thru webinars and vendors in the industry. retail or store purchase apparel is not the same as most wholesale aparrel.
for one thing the sizing is different, then retail tees and apparel has a special chemical for sizing and colorfastness. another thing is the cut and sizing is different.
a lot of apparel decorators, me included do not process customer supplied apparel for this same rreason. last, but least, some of the colored apparel in retail color will not come back vs wholesale manufacturers.
one tip is to put it in front of fan if ur in a hurry, that will cool it down and bring the color back if it's gonna return.
good luck

I'd say that platen marks are mostly due to excessive pressure. If you already tuned down the heat try less pressure, use a teflon sheet if you're not doing it now, so avoid any staining from the platen edges.

Unless you have the pressure or temp dialed WAY up, it's most likely just due to the moisture evaporation mentioned above. You can spritz it with water if you are really worried about it, otherwise, it will go away as the shirt re-absorbs moisture from the air.
A poly shirt is going to scorch before a cotton will, what temp/time are you pressing at?
I used to be terribly worried about press marks, until I realized that most people don't even notice it, even right after the shirt is pressed.

Hey guys thanks for your responses, much appreciated. I set the heat at 170 degrees celcius, not sure what that is in F. I used a teflon sheet and firm pressure. I have test washed a shirt but I can still see the square marks, albeit faintly  Do people really not notice them? I guess I just have to be real careful when dealing with polyester in the future. |

You may have used too much pressure, when I do 100% polyester I don't use very much pressure at all.

Ok, that's only slightly too hot. T'flex plus says 330 to 335 degrees.
I say it's pressure.

Will pressure marks eventually disappear or wil the shirts have them for good. I'm not sure what I should say when I hand the shirts over. Boy am I in a pickle over this one!

How long has it been since you pressed the shirts? When you say they are poly, are they poly T's or something different, like a dri-weave, football jersey, etc?
