MIS-VM hextone and 1290 printers-Problems with tonality
2002-07-19 by jimenez12fr
I am using the above combination with Paul Roark's curves, but I am getting a non-linear greyscale. When I print the scale, between 40 to 80% grey there is no evolution, and there is a jump just before (around 30%) and after (around 90%). I think this is called macro banding. The prints of actual photos show the corresponding shart transition from a flat midgrey to white and dark values, making the print look very "digital". I think I have all the parameters well set, though my software is mostly in French so sometimes it is not easy to get the options correctly set in the print menu. The only option I can't find in the Color settings, where there is no "embedded 4 colours" or something like that and instead I have "embedded 5 colours". I have tried different colour settings, different paper options, speeds, etc. It is curious that I get relatively linear transitions without applying the curves and printing directly after having transformed the image from greyscale to RGB, but still it is not perfect. I have played as well with transfer functions in the print menu, but I am not sure of what I am doing and it is not recommended. The inks are charged in the right order, I am pretty sure (unless there is a mistake from MIS in naming the bottles) Any suggestions of what to try? Should I twickle the sliders, transfer functions? Thank you in advance. Miguel
