Affected Product(s): EPSON Stylus Photo 2000P, Stylus Pro 7500 and Stylus Pro 9500
Subject: Updated drivers to address Metamerism
This bulletin provides information on which updated drivers to use for the EPSON Stylus Photo 2000P, Stylus
Pro 7500 and Stylus Pro 9500 which address the issue of Metamerism.
Please Note: Use of this driver is optional. If you are producing prints that will be displayed under indoor
lighting conditions at 6500oK this version of the driver is not recommended. If you are currently using a
customized ICC color workflow it is very likely the profiles will need to be recreated for use with this new
driver. This driver is also not recommended where prints will be viewed under a controlled light source and in
applications of Fine Art, Photographic, or Black and White printing where ultimate print quality at all viewing
distances is the primary requirement. The current driver and this new driver cannot be installed at the same
time. You must first remove the current driver before installing this updated driver.
Overview of Metamerism:
RODUCT SUPPORT BULLETIN
P
Metamerism is the phenomenon of color prints being perceived differently when viewed under different light
sources. This phenomenon is present to varying degree in all forms of pigmented ink printing and it is not
possible to totally eliminate it. Unlike the EPSON Stylus Pro 5500 and the EPSON Stylus Pro 10000, which
have hardware features designed to reduce Metamerism, the earlier model EPSON Stylus Photo 2000P, Stylus
Pro 7500 and Stylus Pro 9500 do not have this same capability. Therefore, Epson has specifically developed a
driver to reduce Metamerism on these products. While this driver reduces the light source color shift issue
noticeable from all viewing distances, closer inspection of 1 ft or less will possibly show a slightly lower level
of image quality which can be described as a coarseness or graininess in neutral, mid-toneand shadow areas of
the print.

Product(s):Stylus Photo 2000P
Subject:Method for Enhancing Gray Scale Output in Adobe Photoshop
This bulletin was created to inform you of a method for enhancing gray scale output for the
Stylus Photo 2000P.
Description of Change:
§ Due to varying paper types, light sources and the four color process black used for
creating grayscale output, images may seem to lean more toward a greenish hue. Using
the following method in Adobe Photoshop the output can be modified to be closer to a
true grayscale.
Method:
1. If the mode for your document is set to Grayscale in the Image > Mode menu, change it to
RGB.
2. Open the Image > Adjust menu and select Curves.
3. Set the Channel selection to Green.
4. Click anywhere on the line and drag the point until Input=192 or enter 192 in the input box
and Output is between 187 and 189.
5. This setting may need to be adjusted due to the paper type, light source and customer’s
preference.
Please see the diagram on page 2 to see how it can affect color perception.
