■ Output Profile
You can select [Auto] or any output profile that has been
added.
■ Rendering Intent
Use a color conversion method to perform color
replacement when different colors are expressed by
combinations of numerical values.
Select one of four different color conversion methods to
perform color replacement.
[Perceptual]
Preserves the visual relationship between colors, so that
colors that appear natural to the human eye.
• This method is useful when the image data includes
many out-of-gamut colors that cannot be printed, and
is most suitable for photographic images.
[Saturation]
Produces vivid colors in the image.
• This method is most suitable for graphics such as
charts and graphs, in which bright saturated colors are
important.
[Relative Colorimetric]
Compares the extreme highlights of the source color
space to that of the destination color space, and converts
all colors accordingly. Out-of-gamut colors are converted
to the closest reproducible color in the destination color
space.
• This method preserves more of the original colors in
an image than [Perceptual].
[Absolute Colorimetric]
Preserves the colors that are inside the gamut, and clips
those that are outside the gamut.
• This method is particularly useful for previewing how
paper color affects printed colors.
■
Max Drops
You can manually set the maximum number of drops for
the ink.
[Image] Tab
• The [Original Type] setting is not available with
the PostScript printer driver. In the [Image

advice of the administrator.
Color Profile
• When [Auto] is selected, the output profile is
automatically configured based on the paper
type and resolution settings.
• When [Max Drops] is set to [Auto], the number
of drops is automatically configured based on
the paper type. Normally, use [Auto].
