white ink using an overflood or underflood, the printing speed will be slightly less than half of what is shown in the table above. Billboard print mode (FB750 only) - Billboard print mode is intended for creating drafts or proof prints. In certain instances it may be used to produce sellable output as long as the buyer and the seller understand that the viewable distance for output generated in Billboard Print Mode is greater than 100 feet (30 m). Billboard Print Mode does not utilize the printer's jet mapping feature, therefore, any missing or misfiring jets reported or detected using the manual or automatic calibrations will not be substituted with known working jets. Print resolution - The 600×300 dpi resolution has a slightly reduced color gamut compared with 600×600 dpi. Gloss / Matte adjustment - The printer is able to adjust how the ink cures to cause it to have a slightly glossy or matte appearance. For matte, both the leading and trailing UV lamps are open during travel of the printhead carriage assembly in either direction. The trailing lamp will begin to cure the ink droplets immediately after being jetted onto the media. For a glossier appearance, the trailing lamp is shuttered during travel in either direction, thereby allowing the ink droplets to spread out slightly before the leading lamp on the following pass begins the curing process. By default, the print modes Billboard, Express, Outdoor Signage, Outdoor Signage Plus, and Indoor Signage use the matte setting (trailing lamp unshuttered). The print modes Indoor Signage Plus, Photo, and Photo Plus use the gloss setting (trailing lamp shuttered). Two exceptions to this are when the printer is configured to use Foamed PVC media or when printing with white ink. In either of these cases, all print modes use the matte setting. See Appendix B for more detail. It is possible to control the trailing lamp outside the default modes mentioned above by creating a custom media type in Media Wizard. Note, however, due to the increased curing energy needed, it is recommended to never shutter the trailing lamp when printing with white ink. Due to the variation in dot gain from matte to gloss, it may be beneficial to use a matching color profile on the RIP. Onyx software provides an extensive set of gloss and matte profiles. For other RIP software, it may be desirable to create a custom profile. Media Wizard settings HP Scitex FB550 and FB750 printers have a pre-defined set of common media types stored in the Media Wizard along with the printing parameters tested and determined to be work best in most applications. A list of the pre-defined media and their parameters can be found in Appendix A of this document. While the printing parameters for these pre-defined media types cannot be changed, it is possible to create a copy, rename it and change the parameters using the printer's Media Wizard. See the HP Scitex FB550/FB750 User's Guide for details. When creating a new media type, choose a media type that best matches the characteristics and change the desired printing parameters. Also, to eliminate Media Mismatch errors, consider creating copies of the media profile in the RIP and renaming it to match the name of new custom media type. Non-white media The printer uses a camera on the printhead carriage assembly to detect the placement and size of the media. This camera works best on white or near-white media that provides a strong contrast between it and the transport belt. When using clear or colored media, select or create a media type from the Media Wizard that has the attribute Detectable by Printer set to Off. When loading 2 ENWW
