Adjust color
Manage color by changing the settings on the Color tab (Windows) or the Color Options or Color/
Quality Options menu (Mac) in the printer driver.
Automatic
Setting color options to the default or Automatic setting typically produces the best possible print quality for color documents. The default or Automatic color adjustment option optimizes the neutralgray color treatment, halftones, and edge enhancements for each element in a document. For more information, see the printer driver online Help.
Print in Grayscale
Select the Print in Grayscale option (Windows) or the Print Color as Gray option (Mac) from the printer driver to print a color document in black and white. This option is useful for printing color documents that will be photocopied or faxed. The product uses the monochrome mode, which reduces use of the color cartridges.

ł
Mac: Open the Advanced menu, or select the appropriate tab with the Color/Quality Options tab. Click the HP EasyColor check box to clear it, and then enable the manual settings.
Manual color options
Use manual color options to adjust the Neutral Grays, Halftone, and Edge Control options for text, graphics, and photographs.
Table 5-1 Manual color options
Setting description
Halftone
Halftone options affect the color output resolution and clarity.
Neutral Grays
The Neutral Grays setting determines the method for creating gray colors used in text, graphics, and photographs.
Edge Control
The Edge Control setting determines how edges are rendered. Edge control has two components: adaptive halftoning and trapping. Adaptive halftoning increases edge sharpness. Trapping reduces the effect of color-plane misregistration by overlapping the edges of adjacent objects slightly.
Setting options
ł
Smooth provides better results for large, solid-filled print areas and enhances photographs by smoothing color gradations.
Select this option when uniform and smooth area fills are the top priority.
ł
Detail is useful for text and graphics that require sharp distinctions among lines or colors, or images that contain a pattern or a high level of detail. Select this option when sharp edges and details are the top priority.
ł
Black Only generates neutral colors (grays and black) by using only black toner. This guarantees neutral colors without a color cast. This setting is best for documents and grayscale viewgraphs.
ł
4-Color generates neutral colors (grays and black) by combining all four toner colors. This method produces smoother gradients and transitions to other colors, and it produces the darkest black.
ł
Maximum is the most aggressive trapping setting. Adaptive halftoning is on.
ł
Normal sets trapping at a medium level. Adaptive halftoning is on.
ł
Light sets trapping at a minimal level. Adaptive halftoning is on.
ł
Off turns off both trapping and adaptive halftoning.

Use the HP EasyColor option
If you are using the HP PCL 6 printer driver for Windows, the HP EasyColor technology automatically improves mixed-content documents that are printed from Microsoft Office programs. This technology scans documents and automatically adjusts photographic images in .JPEG or .PNG format.
HP EasyColor technology enhances the entire image at one time, rather than dividing it into several pieces, which results in improved color consistency, sharper details, and faster printing.
If you are using the HP Postscript printer driver for Mac, HP EasyColor technology scans all documents and automatically adjusts all photographic images with the same improved photographic results.
In the following example, the images on the left were created without using the HP EasyColor option.
The images on the right show the enhancements that result from using the HP EasyColor option.
The HP EasyColor option is enabled by default in both the HP PCL 6 printer driver and the HP Mac
Postscript printer driver, so you do not need to make manual color adjustments. To disable the option so you can manually adjust the color settings, open the Color tab in the Windows driver or the Color/
Quality Options tab in the Mac driver, and then click the HP EasyColor check box to clear it.
