EPSON PRODUCT SUPPORT BULLETIN Date: 05/02/2002 PSB No.: 2002.05.001 Reference: N/A Originator: RR Authorization: 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: 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-tone and shadow areas of the print.
