marks on t-shirts problem

[kris_hm]

Hi,
My heat press (heating plate) is leaving big, square marks on t-shirts. I though it will be ok after first wash but it isn't :/ still can see big square. I'm using very light pressure for sublimation so it shouldn't be that reason.

also even after first wash the surface of the t-shirt where subli paper was, is bit different and looks more bright and white then the rest of the t-shirt.

will appreciate any suggestions

this may help.

no paul. that thread is about a marks left by paper. mine are left by heat press itself

All flat presses leave marks on tee shirts, but those normally disappear when the tee is first washed and certainly when it is put in a tumble dryer.

i had similar with baseball caps
to the extent where i'm not doing caps anymore with my cap press
i'll prob keep them for embroidery or sell them as blanks

it looked horrid

do you use a teflon sheet at all ?? if you dont - do, if you do - don't and see what the difference is and let us know - maybe use a sheet or something to see rather than t shirts

[kris_hm]

yes, I'm using one teflon sheet from the top. I'll keep trying changing settings :/
I was hoping to start online sale soon. if you sale online, do you send some advice to customers, like: "press marks will disappear after wash" or something silly like this???

Immediately after pressing it helps a little bit if you stretch the shirt sideways and top to bottom.

Kris, there has to be something not right, i pressed 109 t shirts this tue/wed, front/back and arm - and after i had left them draped over the frame where i stack them after pressing, you could not see the press square. I am using a good weight of black T, the press mark always goes as the t cools down - same for hoodies - i did 38 of those as well this week. (all in vinyl i do add)

Maybe the Pressure for the weight of shirt is not right, or the temp, post up what you are using, from the t to the paper, to the press to the temp & time & pressure and that will help folks take it one step at a time

ok, my pressing details:
heat press: stahls hotronix maxx
t-shirts: XPRES, 63% poly
time: 78 s
temp: 187 C
pressure: light
