In message 1816 I reported on a problem that is still not resolved, regarding a weird print of the inkseparation file. This is one of the steps you'll go though while creating a new paper/ink curve. I have posted a scan of the inkseperation.psd print, you'll find it in the Photos folder. Below this message, I'll state the descriptor file that I created for this print. The print shows color wedges that are not like they should be. Please take a look and I hope you could come up with a usefull hint. I have created good profiles in the past, but now I am doing something wrong. This is what I do: drop new curve desriptor file on 'curve drop box' open inkseparation.psd without any assigning a colorprofile print without colormanagement in print with preview in QTR settings: select calibration mode and select the calibration quad file in curve 1 I use OSX.4 and the latest QTR version. link to scanned print http://ph.groups.yahoo.com/group/QuadtoneRIP/photos/view/82f2?b=1 # # quadtone curve descriptor file # # # the printer name # the curve name # no spaces or special characters, except - or _ (dash or underscore) # PRINTER=QUAD2100 CALIBRATION=YES GRAPH_CURVE=NO # # number of inks must be 4, 6, or 7 # the ink limits are percentages # usually they are all the same but they can be individually set # N_OF_INKS=7 DEFAULT_INK_LIMIT=100 LIMIT_K= BOOST_K= LIMIT_C= LIMIT_M= LIMIT_Y= LIMIT_LC= LIMIT_LM= LIMIT_LK= # # Describe Usage of each Ink: K,C,M,Y,LC,LM,LK # All Inks of Printer must be listed # # # Gray Partitioning Information # N_OF_GRAY_PARTS=2 GRAY_INK_1=K GRAY_VAL_1=100 GRAY_INK_2=LK GRAY_VAL_2=45 GRAY_INK_3= GRAY_VAL_3= GRAY_INK_4= GRAY_VAL_4= GRAY_INK_5= GRAY_VAL_5= GRAY_INK_6= GRAY_VAL_6= GRAY_INK_7= GRAY_VAL_7= GRAY_HIGHLIGHT=6 GRAY_SHADOW=8 GRAY_GAMMA=1 GRAY_CURVE= # # Toner Partition Information # N_OF_TONER_PARTS=0 TONER_INK_1= TONER_VAL_1= TONER_INK_2= TONER_VAL_2= TONER_HIGHLIGHT=2 TONER_SHADOW=2 TONER_GAMMA=1 TONER_CURVE= # # Unused Inks # N_OF_UNUSED=2 UNUSED_INK_1=C UNUSED_INK_2=M UNUSED_INK_3= UNUSED_INK_4= # # the following is a special UltraChrome ink flag it copies the # light-black curves to the light-cyan, light-magenta and yellow inks. # this insures that the LC and LM inks are used to directly neutralize # the color of the light-black. # the color balance of inks is controlled by the LIMIT_... values above. # UC_NEUTRALIZER=YES LINEARIZE=
