Out of Gamut, ICC profile issue?

[LollipopCrafts]

hi Guys,
Hoping someone can point me in the right direction before I chuck everything out of the window.

Been printing a while, mostly mugs which are fine. I have also done glass chopping boards, coasters, clocks etc, all with no issues until this week.

The mugs are still ok, but all the glass stuff is too dark and very yellow. I thought I was overcooking them, so I played around with the settings... now they aren't as dark but a bit washed out - and still yellow.

I've tried different settings in photoshop, perceptual etc, no change. I tried a different ICC profile, one for my small printer, and although the out of gamut warning did not show, those colours too were washed out.

I at first thought it was the different make of coaster, but comparing that to an mdf one that I know prints fine showed the same result, so probably not the coaster itself.

I've attached a photo of the end result of the latest test. The only one that isn't yellow is washed out....

If anyone has any ideas, I'd be really grateful, thank you.

Edited to add, I use a MAC, an Epson 14100 printer, along with Ink Experts paper and ink. Correct ICC profile for that combo.

Just checking if I have this right
Mugs are still printing fine, but coasters aren't?
You have different profiles for ceramic, glass and mdf?

Thanks for your reply,

By the time I posted, everything was either yellow or washed out. Mugs were better than the glass but not a lot. Since then I have re done the images, and they print better, but some mugs still look washed out.

I think a lot of it was the colour balance was wrong, but I had to take time out to see this as I'd ended up not seeing the wood for the trees!!

Did you change anything?
Ink, Paper, Printer, mug supplier, press time, temperature etc?
Have you run a print head test?
