Blacks are brown. Please help

[qwertqwerty]

Hi,

I don't sublimate that much. Last year I purchased an Epson ET-2750 printer and Sublinova Ink from Ink Experts. I also have a Galaxy GS-203 mug press.

I use SubliStyle paper also supplied by Ink Experts, also I have used other premium brand sublimation papers like A-Sub.

I have tried various temperatures/time and the the blacks are never solid. They are either faded where I have not used long enough time/temp and still have a brown tinge. Or I can increase the time/temp to get full coverage but the blacks still have brown tinge.

I have tried bother ICC profiles they sent me including one specific to ceramic and still no joy.

They have been super helpful but I still don't get solid blacks.

Before I purchased this printer I had a basic Epson printer and generic sublimation inks and a cheap Chinese press. The blacks used to be solid, the colours were off which I why I invested in the new gear.

I really do not know what to try next as I have been through so many mugs, and because of the blacks I cannot possibly start to sell them. Any help would be amazing. And if your suggestions work a crate of beer from Amazon will be in it's way to you.

Thanks in advance :-)

Black usually turns brown from overheating. If you can post a few pics of the faded mugs this might help. Have you checked all of your settgins in software etc?

You don't mention the brand of mugs you are using. Maybe they have a crap coating.

I use both mugs from Signzworld and MDP. I have always used these mugs, and before I got the Epson ET-2750 and Sublinova ink from Ink Experts the blacks were sharp and deep.

Ink Experts have been helpful, and send 2 ICC profiles. The colours are fine, the blacks are always brownish.

I have tried everything from 180c @ 150 Seconds up to 200c @ 180 secs.

To get a decent full coverage with no fading I use 150c idle, 200c cook temp and 150sec. But no matter how much temp/time the blacks are brownish. Even when there is fading at the edges still brown.

I am going to do 3 mugs tomorrow with a test pattern. 1 x 180c 180sec, 1 x 185c 185sec, 1 x 190c 180sec all at idle 100c.

I have attached my current print settings.
