Hello list, would be a great help to get some advice using targen/printarg. I want to make a target for an inkjet printer (CMYK + CM light) with a larger number of test patches. I thought that -d5 must be the right option in targen. But the printer RIP obviously can not work with more than 4 channels. The most of the patches in the .ps file are almost black and the .tif files are not accepted because of their alpha channels. Using the -f or -N option doesn't change anything. Other questions are: should one include a preliminary profile either an older printer profile or a profile created with a smaller number of test patches, does it make sense to use more than the default white color test patches and should one use single channels and Gray axes steps? I would be pleased to get examples of reasonable command lines for targen and printarg to save me from my confusion Regards Michael
