I am printing from a MAC OSX 10.8.5 Using the print tool and a QTR curve for a digital negative. I am using Pictorico ULTRA film. When printing to a Quad 3880 (UCpk) the negative has no banding or printing artifacts. When printing to a QuadR3000, the negative has banding along the leading edge of the pictorico and the trailing edge of the pictorico. The banding does disappear in the middle of the page. I stymied as the R3000 printing both color and B&W perfectly on pictorico. Any thoughts about what might be going a miss? Cheers, John
