● Click Optical Density to open the Optical Density window. Verify that the OD values match the values in the table according to the substrate type defined. Figure 6-7 Optical Density window 16. Follow the wizard instructions to complete the calibration procedure. Make sure that all colors pass the color adjustment procedure. Exceptions If high color accuracy is needed, the exact solid OD values should be documented and changed whenever the substrate is installed in the press. ● Do this by clicking the Setup button in the Short Color Calibration wizard or the Full Color Calibration wizard. ● The regular definitions (gloss, semi-matt, matt) are usually sufficient for best color performance. If the color adjustment fails when adjusting the 100% OD values, verify that the ink parameters are correct (density, conductivity, temperature). ● Where the ink parameters are correct, and the color adjustment fails when adjusting the 100% OD values, the problem is probably associated with the substrate type definition. ● If the developer voltage is too low, select a glossier substrate type, if it is too high, select a less glossy substrate type.
