3.2 Which colors can be reproduced? The colors that can be reproduced vary between different printers and different printing media. At HP, we analyzed various environments and reached the following conclusions: • Glossy media (such as High Gloss Photo) has a much wider "gamut" (amount of reproducible colors) than matte media, such as Heavy Weight Coated. Typically, the main difference resides in the darkest tones (those found in shadow areas of pictorial images) and in the most saturated colors (vibrant Red or Blue). • The cyan ink is not as saturated as the cyan found in traditional silver-halide pictures. This may lead to problems when reproducing saturated cyan (sky blue) or dark blue (navy blue). • The darkest blacks are difficult to reproduce, especially on coated media. Sometimes, the problem is to achieve the desired darkness; in other cases, the darkness is correct but has a color cast (green or pink tint). In any case, the fact that an original image shows colors that cannot be matched exactly does not mean that the copy will be unacceptable. It will depend on the relation of these colors with the surrounding ones and their "criticality". If the affected colors are not well reproduced, but the surrounding ones are, the result is normally acceptable (the difference may be barely noticeable). On the other hand, when a color must be reproduced as accurately as possible (such as colors in a company logo) even a small deviation may cause the job to be rejected. The following images show the non-reproducible colors for certain printers and media as patches surrounded by a white square. This test has been based on the IT8.7/2 target provided in the scanner maintenance tool, which is a silver-halide picture and has been scanned and reproduced with the HP Designjet 500/800, HP Designjet 105x and HP Designjet 5500 printers on High Gloss Photo and Heavy Coated media. Please note that the result may vary if a different original, a different media or a not well-calibrated printer is used.

3.2
Which colors can be reproduced?
The colors that can be reproduced vary between different printers and different printing
media. At HP, we analyzed various environments and reached the following
conclusions:
•
Glossy media (such as High Gloss Photo) has a much wider “gamut” (amount of
reproducible colors) than matte media, such as Heavy Weight Coated. Typically,
the main difference resides in the darkest tones (those found in shadow areas of
pictorial images) and in the most saturated colors (vibrant Red or Blue).
•
The cyan ink is not as saturated as the cyan found in traditional silver-halide
pictures. This may lead to problems when reproducing saturated cyan (sky blue)
or dark blue (navy blue).
•
The darkest blacks are difficult to reproduce, especially on coated media.
Sometimes, the problem is to achieve the desired darkness; in other cases, the
darkness is correct but has a color cast (green or pink tint).
In any case, the fact that an original image shows colors that cannot be matched
exactly does not mean that the copy will be unacceptable. It will depend on the relation
of these colors with the surrounding ones and their “criticality”. If the affected colors are
not well reproduced, but the surrounding ones are, the result is normally acceptable (the
difference may be barely noticeable). On the other hand, when a color must be
reproduced as accurately as possible (such as colors in a company logo) even a small
deviation may cause the job to be rejected.
The following images show the non-reproducible colors for certain printers and media
as patches surrounded by a white square. This test has been based on the IT8.7/2
target provided in the scanner maintenance tool, which is a silver-halide picture and has
been scanned and reproduced with the HP Designjet 500/800, HP Designjet 105x and
HP Designjet 5500 printers on High Gloss Photo and Heavy Coated media. Please note
that the result may vary if a different original, a different media or a not well-calibrated
printer is used.
