Printing Preferences
To extract black areas from color images, several selections can be made.
• Select black panel extraction type:
- Disable black extraction does not use the K panel for any part of the image. This
selection will have the effect of rendering all black images as YMC composite.
- Print YMC composite and K black uses both the K panel and the Y, M, and C
panels to print the portions of the image that are identified as black. This selection will
result in a dark, black image; but the edges will be smooth (due to the continuous tone
nature of the YMC dyes), not the sharp edges typically desired for a barcode.
- Print all black data uses only the K panel to print the portions of the image that are
identified as being black.
• Apply black extraction on: Note that this function is dependent on the image having
areas defined as text, graphics (lines, rectangles, and other non-text graphic objects), and
bitmaps (color images, photos, pictures, etc). If the image is flattened, then this function
does not apply.
- Black text applies black extraction to areas of the image identified as text.
- Black graphics applies black extraction to areas of the image identified as graphics.
- Color bitmaps applies black extraction to black areas of a color bitmap. By default,
only areas with a RGB level of 0,0,0 shall be treated as black. For adjustments, see
Black level settings below.
- Black bitmaps applies black extraction to areas of the image identified as bitmaps.
This option will extract only black out of monochrome bitmaps, but not from
color bitmaps.
• Black extraction from color images
- Black level:
Every dot of a printed image has an RGB color value that ranges from 0, 0, 0 (pure
black) to 255, 255, 255 (pure white).
The black level setting allows the user to specify the threshold value for any given
pixel to be treated as black. The maximum setting is 25, 25, 25.
