Printing digital photographs
Printing with six-ink color
Your printer can print with six-ink color to enhance the quality of printed photographs. Print
high-quality grayscale photographs by using a black print cartridge and a tri-color print cartridge, or
by using a photogray print cartridge and a tri-color print cartridge. To perform six-ink color printing, a
photo and a tri-color print cartridge must be installed together. To obtain a list of supported print
cartridges for your printer, see
Supported print cartridges .
NOTE You can print high-quality black-and-white photographs using a gray photo print
cartridge, combined with the tri-color print cartridge.
To replace the black print cartridge with the photo print cartridge, see Installing or replacing the print
cartridges
NOTE After you install a new print cartridge, the printer will automatically align the print
cartridges and use one sheet of paper to print an alignment page. If you have higher-quality
photo media loaded in the input tray, you may want to load a sheet of plain paper before
installing the new print cartridge.
Guidelines for printing photographs
■ For the best results when printing photographs and images, choose Best mode and select an
HP photo paper in the printer driver. Best mode uses HP's unique PhotoREt IV color-layering
technology and ColorSmart III color optimization technology to create realistic photo images,
vivid color output, and extremely sharp text. With PhotoREt IV, a greater range of colors, lighter
tones, and smoother gradations between tones can be achieved, ensuring the best photo and
image print quality.
Alternatively, select Maximum dpi, which provides up to 4800 x 1200 optimized dpi* for optimum
print quality. See
4800 x 1200 optimized dpi .
*Up to 4800 x 1200 optimized dpi for color printing and 1200 input dpi. This setting might
temporarily use a large amount of hard disk space (400 MB or more) and will print slower. Photo
cartridge, if present, further enhances the print quality.
■ To print borderless photographs, see Printing borderless .
■ It is recommended to remove each sheet of paper as it prints and set it aside to dry.
■ If the printed colors visibly shift towards yellow, cyan or magenta, or there is a tinge of color in
the gray shades, you need to calibrate the color. See
Calibrating the color .
■ If you install photo print cartridges, align the print cartridges for best possible print quality. You do
not need to align the print cartridges every time you install a photo print cartridge, only when
necessary. See
Aligning the print cartridges .
■ To store a print cartridge, see Storing the print cartridges .
■ Always hold photo paper by the edges. Fingerprints on photo paper reduce print quality.
■ Photo paper should be flat before printing. If the corners of the photo paper curl more than
10 mm or (3/8 inch), flatten the paper by putting it in the resealable storage bag, then rolling the
bag on a table edge until the paper is flat.
