I've used mugs from various sources and have always started with temperature of 180C and 180 seconds with a medium to firm pressue which seems to be a fairly standard start point. Colours have always been strong and vibrant, only time they were dull was when I first strated and used wrong side of paper (doh!!) even then black was better than your photo suggests.

Thanks. I'm getting there. Had it set as fah instead of celsius...doh!
Now, the red text shades differ in colour. It's the same on paper. Some are red, some letters are pinky.
I'll attach a picture.
Cheers

Yea I've noticed that reds seem to be problem colour, I'm using the Powerdriver with the Ricoh printer and I cannot seem to get reds to match print to screen, other colours and photos don't seem too bad. Reading previous posts a custom profile and the win driver maybe better but I've always managed to get something acceptble and I've never had a mug back

Try increasing your pressure a little I have mine so its not a struggle but the tension is noticeable this might help a little with the colours I don't know if its just the image but your black seems a little brown too a lot better than the first one though

If that is supposed to be black then take your temp down 10 degrees. Keep your time around the 180-240 seconds mark

Keep bringing them both down until you find that sweet spot.
