Color space
A color space is the reproducible color range (color gamut
characteristics). DPP supports the following five kinds of color space.
sRGB :
Standard color space for Windows. Widely used for
the standard color space of monitors, digital
cameras, and scanners.
Adobe RGB :
A wider color space than sRGB. Mainly used for
printing for business purposes.
Apple RGB :
Standard color space for Macintosh. A slightly
wider color space than sRGB.
ColorMatch RGB : A slightly wider color space than sRGB. Mainly
used for printing for business purposes.
Wide Gamut RGB : A wider color space than Adobe RGB.
Refer to the color chart below for the color area of each color space.

CMYK simulation profiles
A profile that simulates colors when printing in a CMYK environment
(printing machine, etc.). With DPP, you can simulate color with four
types of profile.
Euro Standard :
Profile normally used for book printing in
Europe, suitable for simulation of standard
European printing.
JMPA :
Profile normally used for book printing, etc. in
Japan, suitable for simulation of magazine
advertising standard color printing.
U.S.Web Coated :
Profile normally used for book printing in
North America, suitable for simulation of
North American standard printing.
JapanColor2001 type3 : Profile becoming a standard in the Japanese
printing industry, suitable for simulation of
JapanColor standard printing.
Rendering intent
Rendering intents are color conversion methods when printing an image.
The conversion method of each rendering intent is shown below.
Perceptual :
Before and after conversion, all colors are
converted to maintain the relationship between
colors. Even where colors slightly change, you
can print a natural-looking image which has
maintained color harmony. However,
depending on the image, the saturation may
change overall.
Relative Colorimetric : There will not be much conversion to colors
which are similar before and after conversion,
but colors which are not similar are converted
appropriately. Because there are little changes
to similar colors which comprise most of an
image, you can print a natural-looking image in
which the saturation has not changed greatly.
However, depending on the image, there are
cases where the overall tone of an image
changes somewhat as colors which are not
similar and highlights change.
