Proofs usually fail due to 1 of 2 reasons, it’s either software or hardware related. Overtime, your calibration and optimization within Fiery XF does fall out of specification, meaning that a profile optimization needs to be performed. Please follow the steps below:
You can greatly improve color accuracy by applying an L*a*b* optimization to a media profile. An L*a*b* optimization provides a better match for the color gamut of the simulation (reference) profile.
However, check the print quality first to ensure that an optimization is really necessary.
1. Connect your measuring device.
2. Start Color Tools, and click Optimize Profile.
3. Click the Info button, and follow the on-screen instructions to optimize your media profile. ● Under Paper white settings, select one of the following:
● Default - Absolute colorimetric—Applies the absolute colorimetric rendering intent from the simulation (reference) profile.
● Suppress paper white—Applies the absolute colorimetric rendering intent without paper white simulation.
● Keep current paper white (no change)—Excludes paper white from the optimization. Paper white WILL be produced during the optimization process, but removed once the 3cc file is added to the target Workflow. You can save your L*a*b* optimization at any time and complete it at a later date. On the File menu, click Save Optimizing Job.
You can apply the L*a*b* optimization to the media profile during the final optimization step. If you do not want to apply the L*a*b* optimization by default, you can select it at any time in Fiery XF.
To edit an L*a*b* optimization
You can complete an unfinished L*a*b* optimization.
1. Connect your measuring device.
2. Start Color Tools, and click Optimize Profile.
3. Do one of the following:
- On the File menu, click Load Optimizing Job, browse to the optimizing job, and click Open.
- Use this setting to load an unfinished optimizing job and continue from where you left off. The only prerequisite is that you must use the same measuring device.
- When you have printed the first chart, click Import Data.
- Use this setting to load measurement values that were obtained with a third-party program. The existing measurement values are used as the basis for creating an L*a*b* optimization. You can use any measuring device, except one that is embedded in the printer.
4. Click the Info button, and follow the on-screen instructions to optimize your media profile.
You can apply the L*a*b* optimization to the media profile during the final optimization step. If you do not want to apply the L*a*b* optimization by default, you can select it at any time in Fiery XF.
To select an L*a*b* optimization in Fiery XF, L*a*b* optimizations must be located in the Profiles\Balance folder in order to be selected in Fiery XF. If necessary, copy the L*a*b* optimization file to the Balance folder before proceeding with the following steps:
Do one of the following:
- Go to System Manager. In the layout area, click the workflow. On the Color tab, open the Color Management pane.
- Go to Job Explorer. In the job list, click the job. On the Color tab, open the Color Management pane.
- Under “L*a*b* optimization”, select the L*a*b* optimization.
- Save your changes.
