    Rich black, what color percentage?

    Hello, I'm trying to offset print a rich black (on aFULLY COATED WHITE LINED CHIPBOARD
    WITH KRAFT BACK), what percentage of CMYK do you use? is it C30 M30 Y30 K100 good? and on 2 color printing do you prefer something like C60 K100 or two black plates (like K50 + K100), and in case in which order?
    Thank you!!!

    It's always depends on what you want AND what is the main color on the page. In most cases C40 and K100 is enough, but when you have e.g. an autumn picture the rich black a little brownish and can use every 4 color for rich black. C40 (or C60) makes a bluish rich black and it seems too cool.

    We are using Black, Warm Black, Cold Black, Double Black and Total black

    Black (standart usage):
    K=100
    C=0
    M=0
    Y=0

    Cold Black (deeper black when blue tones are mainly used on other graphics):
    K=100
    C=40
    M=0
    Y=0

    Warm Black (deeper black when other colors on label/print are warm):
    K=100
    C=0
    M=40
    Y=0

    Double black:
    (Two black plates, using on some dark black boxes, when there are almost no other colors and Total black can´t be used due to material characteristics or with matte varnish.)
    K1=100
    K2=40

    Total black:
    Only in some cases, mainly when customer gives us graphics of magazines, where are some impure black areas with something overlaping or under theese zones.
    K=100
    C=20-40
    M=20-40
    Y=20-40

    It is up to our main graphic designer and pressman what they choose.
    If we do not have time, simply put 100+40, it helps to prevent uneven black areas and paper pattern.
    I believe to stay under 50% of additional colors, it is due to raster starting to be negative (dot area) from this point usually.
