Precautions after the completion of the adjustment
The adjustment may possibly change the hue of the text and the image, such as a photo image, on the printout.
Therefore, carefully perform the adjustment, while checking the printouts.
Remarks
To check the definition of black text
When creating a PDF file, 100% black may not be defined as follows, depending on the application settings:
"100% black" indicates the following values:
• RGB data: RGB = 0%
• CMYK data: CMY = 0%, K = 100%
As a result, text, which should be defined as 100% black on the application, is not defined as 100% black on
the saved PDF file. (A small percent of color data is defined.) Eventually, all color toners (C, M, Y and K)
will be used to print it.
If printing is performed on a PCL6 printer driver, print data are captured as RGB data. If black text is
defined as 100% black (CMY=0%, K = 100%) for CMYK data on a PDF file, it will not be converted into
100% black (RGB = 0%) for RGB data on Acrobat, and it will be printed in colors. (It is recommended to
print CMYK data on a PS3 printer driver instead of a PCL6 printer driver.)
Use "Output Preview" on Acrobat 7.0 Professional to examine the color definition on the PDF file.
* For further information regarding the Output Preview, refer to an appropriate manual or the Help menu of
Acrobat 7.0 Professional.
