Re: mottled yellow position in QTR calibration test print

The QTR Calibration Mode print shows the inks and results way past the ink limits. Mottling above the ink limit is rather normal. It's not just the darkest patch that you look for, it's also the smoothness of the printing. Some papers are particularly bad at the mottling. EEM comes to mind. Most heavily calendared alpha cellulose bases cannot absorb as much water as a good cotton base. With matte papers that do not have barriers between the coating and base, the base is part of the reservoir of the water. Getting those limits right for the paper involved is part of the game.
