when i got to end of vinyl roll i had stripes along vinyl?

[Andy Gorman]

It sounds like pressure marks on the last bit of the roll. You can get rid of these usually, by applying heat (a hairdryer will do) for several minutes, either before you cut or once it’s on the van. The gloss does come back.

I agree, it is annoying.

I hate this problem too.
Over time I have had quite a bit of vinyl replaced due to this problem, I hate when you order 5mtr of specific colour and you get the end of a roll with around 4.5mtr being unusable.
Interesting what Andy says, never tried that, but I don’t see why I should do it unless I was in deep **** and had to cut vinyl that day.
I expect all the vinyl to be in tip top condition.

Your a star.
Got the heatgun out, just a quick blast over and hey presto back to gloss.
You’ve got me out of the you know what, and to think of all the vinyl I’ve wasted over the years.
Cheers mate I owe you a beer or two

No problem, glad I could help.

The problem is caused by the tightness of the wind on the roll. Vinyl is soft so it takes on an impression of the cardboard core. Especially noticeable when the cheaper, rough cores are used. In an ideal world they would put an extra metre or 2 on the roll to allow for this, but the vinyl isn’t really permanently damaged. It’s just a pain having to warm it up sometimes. A place I once worked at had an oven for drying stuff and I used to loosen up the rolls and bung them in there for 5 minutes. It will fix itself once it’s on the van for a few days, but you can’t send a customer away with anything that isn’t perfect, even if it will fix itself.

Great tip from Andy, just spent 5 mins looking for a bad piece of vinyl
found some applied heat and back comes the gloss. After 10 years I never knew you could do that. Well done mate.

Yippy (hot)

What a fantastic tip

I had this problem the other day and had to bin about three mtrs on vinyl

The vinyl had taken on the texture of the cardboard tube it was wrapped around

If I knew then what I know now………

Thanks Andy you are a star

Yeah, i returned a roll or two for this reason years back.
fortunately I found out early on about it. It’s just what andy said… Here they call it Mottling. The vinyl Being Cast and conformable takes the shape of the liner of core.
After i had the explanation, i just used it and after installing, it goes away. If you put it on a truck, or panel, it will clear up in the sun or a heat gun, within minutes.
