Make sure you check the pressure of your heat press too.
Expressions Heat Transfer Vinyl
Good Morning all,
New to the Forum but have been using for research for quite a while.
I just dove head first into heat transfer vinyl. I have a vinyl cutter that works fine and a lower heat press that seems to do the job.
My questions refers to the Expressions Heat Transfer vinyl that i'm using. I have tried to use the factory time and temp settings, but it seems way too cool and not long enough.
The manufacturer recommends something like 310 degrees for 1-15 seconds. When used at this setting the vinyl barely sticks.
I up'd to about 350 for 30 secs and it seems to stick better in the middle of the design but when I stretch the shirt for quality, the vertical edges wrinkle and peel off the shirt where the middle stretches with the fabric.
Any recommendations?
(other than "just give up now")

Why not just switch to proven brand?....I like Siser or Spectra Eco Film.....Others will tell you they like Joto Paper or Thermoflex....
I did some research and found Expressions is just a reseller or Siser. So I searched that and got some possible answers.
I turned temp to 400 for 15 and that worked but scorched fabric.
I'm playing with the pressure now.
Thanks guys.

Have you measured your temperature with a probe?...
You do not want to use too much heat or time as the will "over cure" the vinyl and adhesive and cause it to fail prematurely.....
Are you pre-pressing to eliminate moisture?....I tend to use way longer time than recommended to be sure moisture is removed....

I pre-press for about 10-15 seconds.
The upped pressure at the recommended temps and times and it's working almost perfect.

I use Siser and use 325 for 10 sec's medium pressure. Works well for me.I pre-press for about 10-15 seconds.

Not sure why you are stretching the shirt but if you are concerned with excessive stretching there is flex vinyl suited for that purpose.
