Hi
I have been buying heat vinyl from Sign Making and Supplies. I have been buying their polyflex vinyl. Previously bought yellow and white, then purchased black (all 50cm rolls) and a few A4 sheets of red/royal blue/orange as I did not need a lot of those colours at present.
The yellow worked fine once I got going, haven't used the white yet, but the issue started when I used the black. I had black text, with some red, blue, and orange, and even a bit of layering, everything worked fine except for a small corner - the Y on mummy in the first, and the corner above the S in the second (as you will see from the photos). I then pressed another item in completely black, and again an issue with one corner. The opposite corner from before. No matter how often I pressed it, it just would not stick. Got to the point where I singed one item
Anyone have any ideas what would cause this?? The seller said he'd never had this before and was going to press some items to check. Not heard back... Just seems weird that it was only the black that had the issue and on a small part!!
This is the vinyl here https://www.signmakingandsupplies.co...lex-2075-p.asp
Anyone else have any other suppliers??
thanks
