I have a Ricoh GX7000 with Ricoh inks which has been fine for ages but suddenly my print quality has gone completely. I have tried mugs, coasters, slates etc but they are all completely awful and unsaleable. Sometime hardly any colour transfers at all and when it does it's very dull and yellow.
I'm at a loss as to what's causing the problem. Can inks go off?? Is the press not up to temperature? I've asked Novachrome but their replies don't fill me with confidence. They suggest i need a new press but I'm getting the same problems with mugs which is a different press.
I don't want to start buying new equipment until I know definitively where the fault is.
All suggestions greatly appreciated.
