first time I have ever seen someone say try it yourself answer your own question,thought this was a help forum but okay I will do as u said and try but thought someone may have a answer before paying double for stretch vinyl and trying to see if it ironed on and stretched then washing and drying and waiting weeks to make sure it holds up before selling any to people who are asking for them but hey we all got time, so I will use mine wisely. Thanks Guys. Yeah I live up to my name.
BTW irons are really not good for doing heat transfer films. Your pressure will not be even and the temps are not really "settable" I would highly recommend a heat press. Even a cheap heat press is much better then an iron. (But i recommend using a quality press)
Again...another reason to test things yourself. There are to many variables to know if the info you get/got applies to your situation.
Humidity, temp, press, brand of HTV/HTF, substrate, pressure, dwell time, etc. all make a difference in durability.
After you do some testing, if you are not happy with the results please come and post what you have done and what you dont like about it or what didn't work as well as photos. Then we can try to give you advice/tips/tricks/etc. which may help get you to your sell able product.
Tip on wash testing...just put it in EVERY load of laundry you do. So if you wash and dry 4 loads today...put it in all 4 wash and dry cycles. I would also wear them for a day or two to "stretch them". Scrape at them a little....like if your pants were rubbing against the print area.
Im sure you get the idea.
