AS-4000 User’s Guide Troubleshooting ❏ Make sure the press has imported an ICC profile Make sure that the calibration data was created on the press that imported the ICC profile. 1. Press the Color Management menu, and then press the Substrate Management tab. 2. Select the combination of target Substrate No. and Print Info. from the list. 3. Make sure the date is displayed in Calibration at the bottom of the Detailed Settings screen. ❏ Check the color accuracy of the press Specify the print information used for printing to check the color accuracy of the press. If the values are below the standard values, try the following solution.
U “If Determination1 or Determination2 Does Not Meet the Standards as a Result of Checking the Color Accuracy of the Press” on page 97 If the Chart is Blurry and the Colors Do Not Match Try the following solutions. ❏ Set a narrower print width for the chart Since calibration was not performed correctly, narrow the print width of the chart and perform calibration again. If you are using a substrate with a width of 250 mm or more and Color Measurement Chart Width is set to Maximum (for substrate wider than 250 mm) on the Press Settings screen in the Maintenance menu, change this setting to Auto . U “To change the width of the color measurement chart” on page 99 ❏ In Print Info.
for the preset, select a print mode with a high number of print passes You can improve the accuracy for color matching by recreating the ICC profile for the changed number of passes. You can also share ICC profiles in modes with a different number of passes. If the Surface of the Substrate is Uneven Causing Uneven Color Measurement Try the following solution. ❏ Set Smoothing Level to On , and then recreate the ICC profile Before creating an ICC profile or printing a color measurement chart, try setting the Smoothing Level to On from Advanced .
However, when Smoothing Level is set to On , the color reproduction accuracy may decline even after group-adjusting spot colors or even if process colors are used. If Determination1 or Determination2 Does Not Meet the Standards as a Result of Checking the Color Accuracy of the Press Try the following solutions. ❏ Replace the substrate Replace the substrate with the one used when the ICC profile or calibration data was created, and then perform the color accuracy check again. If you want to print on another new substrate, introduce the new substrate. 97
