more color calibrations have been performed, pressing the Reset button returns the status to Recommended. ● Done status indicates that a color calibration has been performed successfully at least once on this substrate, and therefore a color reference state is defined. ● Obsolete status indicates that the last color calibration may be out of date. For instance, color calibration status is set to Obsolete whenever a printhead is replaced. The color reference state remains defined. ● N/A indicates that this substrate cannot be color-calibrated. NOTE: Generic substrates cannot be color-calibrated, although such substrates may be suitable for color calibration. You can color-calibrate clones of most generic substrates. TIP: If color calibration fails, it is worth trying again. TIP: If the first color calibration of a new substrate fails, press the Reset button before trying again. Color calibration for the 360 or 370 printer The color calibration test chart is printed using a fixed print mode with a high number of passes and fixed curing and drying settings to ensure printing consistency. However, parameters affecting substrate advance should be fine-tuned, and printheads should be aligned, before starting color calibration for the first time. To start color calibration of the loaded substrate from the front panel, select , then Image quality maintenance > Color calibration > Calibrate. Color calibration can also be run while adding a new substrate (see Add a new substrate on page 92). NOTE: Only substrates at least 61 cm (24 in) wide can be calibrated. The calibration process is fully automatic and can be performed unattended after you have loaded substrate of the type you wish to calibrate. The process takes about 15 minutes and consists of the following steps: 1. The color calibration test chart is printed, which contains patches of different densities of each ink used in your printer. 2. The test chart is scanned by the HP Embedded Spectrophotometer. If the scan cannot be completed successfully, a message is displayed on the front panel; see Front-panel error codes on page 160. 3. From the measurements made by the spectrophotometer, the printer calculates the necessary correction tables to apply to your print jobs, for consistent color printing on that substrate type. Calibration should be done in any of the following circumstances: 100 Chapter 4 Substrate settings ENWW
