Hi !!

i came from Komori LS440SP and Komori GL840P
on this machines we got an "gray field" as graybalance in the color bar.
now im on Komori GL 540 and im missing the "gray field" <- i think on the place where the grayfield was is now the 5. color !?
how to get back my graybalance field in color bar ?
which colorbar i have to use ? (name)

a whole list of color bars is available from Komori for each press or you can make / edit your own.
talk to me
 
  • when the name of the colorbar file has a GST at the end it is one with a tint target - your gray scale

    you should use 5(color)G(Gray) S(solid) T(tint)
    I can send you as an EPS file
     
    35 mm patches. This is a special colorbar with a 25% black and a corresponding CMY gray patch, a 50% black and CMY gray patch and a 75% black and corresponding graypatch. I uploaded an image also.

    Yes it is for a 29, we have PDDC-SII on the presses and have not paid for the graybalance readablity if that matters. I'll just like it to read the density if possible. I know that might be asking alot but thanks for your help.
     
  • . . . Did you know that you can measure the 50M/40C/40Y grey patch as a ‘density’ and know everything about your press sheet?
    Set you densitometer to “all” filters.
    Take a reading of the grey patch- the V is the overall density ( should be around .60). Look at the y/m/c densities- they should be within .03 of each other. The ‘target’ is to have them all the same.
    Example- V.65 M.55 C.60 Y.54
    Since the V # is high you lower the (higher #) density - Cyan!
    If the V was .55 you would increase the M/Y densities!
