Problem with pics on mugs

[becky13299]

hi i am new to this and would be grateful for any help. we have just bought the domglobal 5 in 1 heat press initially to help my rhinestone business but as i have the other attachments thought i would give the mugs ago. we have an epson d120 with continuous bulk feed ink and on the first few mugs have had the same problem

we have tried setting the temp at 180,185, 190, 195 and have gradually increased the pressure but always heating for 310 seconds it always seems to happen around the edges but also in various other places

can anyone please tell me if they have had the same problem and how they solved it
kind regards becky[attachment=1:25h3l96u]021.JPG[/attachment:25h3l96u][attachment=0:25h3l96u]022.JPG[/attachment:25h3l96u][attachment=0:25h3l96u]022.JPG[/attachment:25h3l96u]

Welcome to the forum Becky

Who is the mug supplier and what paper/inks are you using?

[becky13299]

the mugs are from bms and the ink from xpres cant remember where the paper was from

Welcome!

Can the defect be felt with fingertips (any residue on the surface?) or it's all visual?

[becky13299]

No defects you cant feel it with your fingertips its all visual

You're cooking for 310 seconds? Usual time is around 180 secs, that could be the first thing to change. temp sounds about right 185/190.

Are the marks consistent throughout prints or do they move?

[becky13299]

the marks move not always in the same place but mainly round the edges

Justin got it there, 310 second is too long, 180 is the norm, try that and see how it goes. Also worth a shot is to flip the mug upside down half way through pressing (90 seconds each way) in case if it's the press that's not giving an even pressure coverage.

thanks will give it a go later and let you know how i get on

I don't think it's the time. While 310s is a little on the long side, I see no sign of blurring or ink migration to suggest that it's in the press for too long. Whatever effect you get from pressing for too long would affect the whole design, not just patches.

It looks like there's two issues going on here. The light print at the edge of the design on the purple mugs looks like a heat blanket issue (which will get worse if you reduce the time). The patches in the print area suggest dodgy paper (perhaps it's been left open to the atmosphere or has had water splashed on it at some stage).

I'd recommend you get a pack of brand new and trusted paper (such as TruPix) and see if that eliminates the patches. It won't eliminate the pink edge, but one thing at a a time.

That'd be my two-penneth.
