Use the High Resolution Sheet Viewer to view sheets (and sheet elements) at high resolution before printing. Sheets appear in TIFF file format, screened and ready for printing on the proofer. Each sheet opens in its own display window in the High Resolution Sheet Viewer, and the display window contains information about all of the color separations in the sheet.
For an Epson Stylus Pro WT7900 printer with clear media and sheets that contain a white separation, the High Resolution Sheet Viewer uses gray to represent clear media. As a result, when you view the separations in the High Resolution Sheet Viewer, the white and colored separations appear on a gray background that represents clear media. You cannot change the color used to represent clear media. The gray color does not print on the sheet; the gray color is used only to let you view white content.
You cannot edit sheets in the High Resolution Sheet Viewer; you can only view them at high resolution. You must fix problems in either the Sheet Editor or the source file, depending on the needed change. If you update a source file, you must resubmit the source file for processing again.
Note: A sheet cannot be open in the Sheet Editor and the High Resolution Sheet Viewer at the same time.
