    Pitstop Pro... change black to 60/40/40/100.

    @Funnybone - the suggested the RGB 0,0,0 to CMYK, does this actually work??

    Seems like on a calibrated machine it would create a muddy black, and look awful next to a 0/0/0/100. In my experience even 0/0/0/100, 60/40/40/100, and 20/20/20/100 will yield a color that is visual ALMOST identical, but density will be different obv. (100 vs 240 vs 160...) When we do our lin, we fake the black a bit in the 95% to 100% input area maximizing the 0/0/0/100 density. Caution, this can cause weird things in photos and such, great for vector though...

    misunderstanding

    Hello guys
    question is simple, Schruda need deep black when he print on his printer.
    during color management in rip whatever you do, is converted to values defined in output icc profile
    Apa_Cska, define in Lab is good aproouch and good hint

    maybe you can print TAC chart measure it, and find what is lowest L value.
    and after that define this color like printer color with exact numbers
    in spot color editor you have possibilities to define color in different ways.
    spot, lab, printer color
    +-+-+-+-+-+ +-+-+ +-+-+ +-+-+-+-+ +-+-+-+-+

    I agree with you. If you work with offset profiles as a source than whatever you do it still will be based on rules of this source and its not so black... Iso coated v2 K100 its just L16 and max profile L is 9. Epson can go darker ryan that :) Efi not always wants to replace process colors with user defined ones, you think you change it but at the end it still the same :) Making a test chart will show you how black can you go with your media profile, you can print a test with cm off as well just to check If media profile does not cut off too much. Then If you find it create a user defined pantone table with lab values and set it up in spot color option with lab as a first to be checked and rebuilt pdf with your own spot color.
