Digital BW, The Print

Hi Paul,
I have set up a Workforce 30 for Eboni MK (three dilutions and the K ink in the two black positions) and use it with PhotoGP (a freeware Gutenprint plug-in for Photoshop CS4). I linearize the curves by modifying the XML curve files associated with the C,M,Y positions. On the other hand I notice that there is an abnormal reduction in some of the ink levels, especially in the Cyan position (I use 2% dilution with the generic solvent according to your formulation - thanks!). I wonder if the ink is leaking out when not in use. Now that you mention the dye inks leaking, I should pay more attention to this!
