I want to use my action list to determine whether my digital press is accounting for black and white or color prints.
So I have three questions about this:
Why does the Page Color Type Report confirm black and white even though the PDF contains a neutral RGB Black? A neutral RGB Black (where the R, G, and B values are equal) is seen as color by the _original_ DFE and costs a 4-color click and not a black and white click.
Our DFE is a PRISMAsync from Canon and accounts for a 4color click when outputting such neutral RGB, not black and white.
Since Enfocus/PitStop provides the Page Color Type Report specifically for DFE users like me, that should be corrected.
If I can't rely on the result, then the preflight report "Page Color
Type" or even the action "Gather page color type" is completely useless.
It would be desirable that neutral RGB is recognized and reported as color, just as it is interpreted by the DFE! Because then I would also have the possibility in advance to correct the print data in time.
I have already contacted the enfocus support. In their reply, they unfortunately do not explain why rgb is reported as black:
...
To explain more about the Page Color Type Chapter in the Preflight Report was created specifically for DFE (Digital Front End) customers who pay a different amount for color pages than for black and white pages.
This reports on the Color Type of a Page, with three possible options that will be reported: Empty, Black and White, or Color. The report emulates a DFE and has the following specific handling:
Neutral RGB = Black and White
K only = Black and White
...
Perhaps someone here can explain to me what the point is of reporting neutral RGB as black and white in the Page Color Type Report, when the same RGB is billed as a color on the original DFE of the printing press.
