Color calibration can be launched from the front panel, after pressing Modify preset, or when adding a new substrate. In outline, the process consists of the following steps. 1. A calibration target is printed. 2. The colors on the calibration target are measured automatically. 3. The calibration target measurements are compared with an internal reference to calculate the necessary calibration tables for consistent color printing on the substrate in use. Factory default calibration tables are used whenever color calibration has never been run. The first time color calibration is run, the current printing color is taken as a reference, and factory default calibration tables continue to be used. This means that, after the first color calibration, the printed colors do not change, but are recorded as the reference for future calibrations. Subsequent color calibrations compare calibration target colors with the recorded reference, in order to calculate new calibration tables for consistent color printing on that particular substrate type. From the front panel, you can delete the current calibration reference and table, leaving the factory default calibration table active, as if that particular substrate had never been calibrated. Press , then Image quality maintenance > Color calibration > Reset to factory. Color calibration as described above is not recommended for the following substrate types. It may be possible to calibrate some of these substrates by using an external color measurement device, driven by an external RIP. ● Non-opaque substrates such as clear film and backlit substrates. ● Substrates with an uneven surface, such as perforated vinyl and punched-window substrates. ● Porous substrates that require the use of the ink collector. Substrates suitable for color calibration include even-surfaced adhesive vinyls (neither punched nor perforated), PVC banners, and papers. 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 96). 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. 102 Chapter 4 Substrate settings ENWW

Color calibration as described above is not recommended for the following substrate types. It may be possible to
calibrate some of these substrates by using an external color measurement device, driven by an external RIP.
●
Non-opaque substrates such as clear film and backlit substrates.

Substrates with an uneven surface, such as perforated vinyl and punched-window substrates.

Substrates suitable for color calibration include even-surfaced adhesive vinyls (neither punched nor perforated),
PVC banners, and papers.
The color calibration test chart is printed using a fixed print mode with a high number of passes and fixed curing
