Making Your Prints Match the


Monitor—Gamuts and Color


Management


Prints don’t look exactly like the image on the
monitor. And just as in darkroom printing, a great
deal of time and money is wasted by photogra-
phers who make print after print until the image is
perfect. Software like Adobe Gamma is very help-
ful, but it only begins to solve some parts of the
problem of getting prints to match the monitor.
Adobe Gamma is available with Photoshop and
Photoshop Elements.
The real problem is that a computer does not
“know” two important pieces of information: How accurately does your monitor
reproduce colors, and how accurately does your printer reproduce colors. All a com-
puter does is send instructions to the monitor and to the printer about what color
each pixel should be. A computer has no way of receiving feedback about how each
device actually illuminates screen phosphors or mixes inks. As a result, when the
monitor and the printer have different “ideas” about what the color “red 220, green
164, blue 139” looks like, the print will not look like the image on the screen. Even
when the monitor is calibrated with Adobe Gamma software, the inks and dyes used
by printers rarely form colors identical to the colors of a monitor (see the sidebar
“Human Vision and Color Gamuts”).
