Calibrating Your System
Sometimes the colors of your original image do not match the
colors you see on your screen and in the final printed output.
This is because of the different color processes your scanner,
monitor, and printer use to produce color.
The scanner and the monitor both create a range of colors by
adding red, green, and blue (RGB) in different proportions and
intensities (an additive color process). Printers, on the other
hand, produce colors by combining cyan (C), magenta (M),
yellow (Y), and black (K) inks (CMYK) to create the desired
hues. This is a subtractive color process.
When you print a scanned image, the image goes through both
the additive and subtractive interpretive processes to acquire
colorthe first when it is scanned, and the second when it is
printed on your color printer. As a result, the printed colors
may not match the colors in the original.
Calibration allows you to fine-tune your scanner, monitor, and
printer to produce colors that are very close to those in the
originals. Use the procedures in this chapter to:
Calibrate your monitor to your scanner
Calibrate your printer to your scanner
Use the resulting calibration profiles when you scan an
image.
