i do 10 secs with parchment like splathead
(not a fan of teflon, leaves a grid pattern on everything, and/or a glossy finish, and monkeys with the heat and time)

light stretch after initial peel and after the repress

if you find the jpss is way too hot for your hands to peel after initial press, don't wait 5 seconds and then peel
it is better to peel when it is just lukewarm, then don't stretch, just re-press with parchment for 12secs and then lightly stretch immediately horizontally and vertically

jpss is bullet-proof if done right, esp. on 50/50 blends (you can experiment with color tee's as well, i've found you need a good dark/black border, but the colors will shift slightly based on tee color - check here for some results)
heavy-heavy pressure is key, as well as time and temp

let customers know not to wash for 24 hours, and add a hang-tag to wash in cold and low dry
before you send them out to customers, give the design a feel and if it feels stiff/solid, give it a light stretch again

Being lazy, I use the same time for the repress as I did on the original. You can get different vinyl surface looks by picking a parchment with the surface you desire, e.g., gloss, semi gloss. or patterned. Repressing is definitely worth doing for both the look and better adhesion to the fabric.

are you still talking about jpss, because it is more of a glue than a vinyl like 3g?

i did not know parchment paper came in different surfaces, do you mean teflon?

i'm surprised there is not any damage to the fibers or smoke/fire after a minute of 375f pressing
assuming you do a hot peel, then re-press right away

I'm talking about vinyl only. 300 to 310 degrees at 10 to 12 seconds. I have found parchments with different surfaces in the cooking section of stores. I only mentioned parchment as it was brought up. I almost exclusively use Teflon, and have a collection of old Teflon sheets with varying surfaces. The new Teflon sheets are usually just smooth, but after lots of use vary a lot.

ok, but this thread is about jpss and your advice could be quite unsafe with it

The first six posts talk about pressing for 10 to 12 seconds, the same as I said, so how is my advice unsafe?

right here, you are suggesting using the same 30 seconds at 375f immediately after a hot peel of 30 seconds at 375f:

... I use the same time for the repress as I did on the original.
