Why does this happen a pink smudge on mugs

Hello Everyone
I'm having issues when sublimating mugs. There is a pink smudge or clouding around the writing Even on Images with no black ink See attachments
It does not happen all the time. It could be 1 in 20mugs or 5 out of 20 mugs or perfect with no problems doing 20 mugs all at the same time and printed on the same day and left to air dry for 2 hours before sublimating.
Printed on an epson L1800 with an icc profile from affinity designer software. Perfect nossle check on printer
Inks are ink experts SubliNova Smart and are indate to March 2022
Paper is Ink Experts 120 gsm style
Mug press J trans Bms Supplies 5 years old but never used till September 2020. (a late starter lol)
Mugs are Mdp orcal coating
Base of Mugs warmed up on heater before sublimating
150 degree idle
180 degrees for 145 seconds peeled straight away when they come of the press and air cooled.
Paper stored in a plastic box with a lid on it and Silcone Gel in the box.
I've tried sublimation direct mugs, Bms Mugs, and Listawood Mugs same problem.
Also tired inkexpress subli-sharp paper and true pix paper.
I just can't figure this out why it happens and asking the experts what else I can try.
Thanks Shane

I get this on a few mugs now and then.
To overcome this I simply dunk the mugs In warm water.

Remove from press remove the paper and dunk and let dry.
as soon as you dunk the sublimation process stops and you should see a difference.

I can let some mugs cool naturally without issue but there are a few that just blur without dunking.

Thanks for the info Mrteajunkie but it already has the pink smudgeing as soon as the paper is taken of. Any other ideas what is causing it?

Leave the paper on, as sometimes you can smudge the ink as you remove the paper - we dunk into water with the paper still stuck on.
Other things could be that the paper isn't stuck tight enough, or you're leaving them in too long

I'll tried that Pisquee by dunking them in warm water with the paper still on.
When you say leaving them in too long do you mean too long a time pressing them in the mug press
Thanks for the reply

Yes, pressing too long

That's the way I do them too. Also, try firmer pressure on your press, it looks like the red may be gassing out.

Thanks all the dunking right away seems too have cured the problem
