White vinyl changing colour

[adlindsay]

Hi,

I've recently done a few football shirt numbers for a friend and the colour from the red shirt seems to be changing the white vinyl to a pink. The shirts are 100% polyester football shirts, can't remember make. The vinyl is Hot Flex from MDP Supplies. The shirts haven't even been washed or worn yet. I've not yet seen the shirts but samples will be heading my way for inspection in a day or two. Just wondered if anyone else had seen similar problems with other vinyl?

Thanks

Andy

please can you let us know the make of the shirts as we have a customer coming to us to put names on about 20 shirts they bought off ebay and i don't want to be having the same problem, i would rather not do these but they are regular customerss who are sponsoring a local boys football team so i can't really refuse. thanks

looks like white is not opaque enough. but it would be strange as i used this vinyl many times and it works great and never changed thecolour. maybe it is optical illusion that human eye can see? little white on bright colour can do lods of tricks for our eyes

Or it could be cheap, crap, white vinyl :biggrin: where was the white vinyl bought from.

I've seen the sublimation block vinyl, I wonder if this is what you need?

It sounds to me like it's just the red showing through the white though.

I did some 100% polyester shirts foc last year as a one off, for a team that were doing a charity match and back then only had a domestic iron.. I have one of the shirts here as my partner played for them and if you look closely the colour looks like the vinyl has turned a shade of grey (on a black top) and this looks like either the opacity of the vinyl is the issue.. or how long the vinyl has been heated for.. as I note that the small logo on the front, which wasn't heated as long - doesn't look like it's been affected..
I also had flex from MDP but only their basic range.

I too had this problem at first, worked out I was pressing for too long.

i seem to remember somthing about this, the shirts are probably sublimation dyed. i believe there is a sublimation block vinyl available whats happening is the red sublimation dye is bleeding through the vinyl. the sublimation block vinyl prevents this i believe it was target transfers where i read about this.

Thanka for the info. Will check the make once I get one back to look at. As far as I remember they were pressed for 15s as specified on the instructions for the vinyl. Temp should have been about right but the gauge on my press is proably not very accurate anyway. When they were pressed they looked fine, so no reason to suspect there would be a problem.

Cheers
