3. Printer-specific Adjustments

Caution after 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.
