Color printing

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.

Manual color options

Use manual color options to adjust the Neutral Grays, Halftone, and Edge Control options for text, graphics, and photographs.
Table 3-1 Manual color options
Setting description Setting options
Edge Control
The Edge Control setting determines the rendering of edges. 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.
Halftone
Halftone options affect color output clarity and
resolution.
Neutral Grays
The Neutral Grays setting determines the method for creating gray colors used in text, graphics, and photographs.
Off turns off both trapping and adaptive halftoning.
Light sets trapping at a minimal level. Adaptive halftoning is on.
Normal sets trapping at a medium level. Adaptive halftoning is
on.
Maximum is the most aggressive trapping setting. Adaptive
halftoning is on.
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 important.
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 small details are important.
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.
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.

Match colors

For most users, the best method for matching colors is to print sRGB colors.
The process of matching printer output color to your computer screen is complex, because printers and computer monitors use different methods of producing color. Monitors display colors by using light pixels that use an RGB (red, green, blue) color process, but printers print colors by using a CMYK (cyan, magenta, yellow, and black) process.
Several factors can influence your ability to match printed colors to those on your monitor:
Print media
Printer colorants (inks or toners, for example)
Printing process (inkjet, press, or laser technology, for example)
Overhead lighting
Personal differences in perception of color
