Edit or create a new Media
Edit existing Media
From the File menu, select either a Open from Controller or Open Media. You can then make changes (for example, reprint charts, and change measurement data).
Media Setup
You are informed that your media has loaded and the details are displayed:
| Media Name | This is free text to enter a name for your media. |
| Description | This is free text to enter a description for your media. |
| Backing Color | A selection of backing color options. |
| Media Width | A selection of available media widths. |
| Screen Setup | For each colorant, you can choose the Screen, Output Bits Per Pixel, and Resolution. |
| Print Bars | The user has the option to choose which ink channels to print and measure, as well as which ones to ignore. The channels marked as "ignored" should not be printed or measured in SMM for dot gain, ink limits, grey balance, and ICC profiling. However, it is necessary for the ignored channels to undergo drop level stages and pinning stages. In SC, the ignored channels are excluded from PrintFlat calibration and ICC profiling. In SPC, the ignored channels are disregarded specifically for ICC profiling. |
| Add White Backing | This will only be visible if you have white in the printer profile. When enabled it adds a white background to the target. |
Linearization only or Linearization and calibration | This setting is for smart calibrator and it will tell smart calibrator if you want to get just linearization data for the specific SMD or linearization and calibration data. |
Nozzle Compensation Enabled | This will allow you to open the 'Nozzle Correction Configuration' window. |
Configure Nozzle Compensation | This button will only be active if the 'Nozzle Compensation Enabled' is checked. When this is enabled if you click it this will open the 'Nozzle Correction Configuration'. |
Print Bars
The section selects which bars are active and which will be measured.
Screen Setup
This section allows the selection of screen, resolution etc.
Nozzle Compensation Configuration
| Compensation Mode | Specifies the way NozzleOut compensation is carried out. Valid numbers are 0, 1, or 2.
|
|---|---|
| Compensation Level | Specifies how many neighboring nozzles to compensate. Valid numbers are between 0 and 5 (inclusive). When set to 0 and compensation mode is not 0, failed nozzles are cleared during screening but no compensation is made, providing a method to turn off individual nozzles in screening. |
| Compensation Scaling | When set to true, the screening process reduces the compensation based on the failed nozzle density. |
| Compensation Factor | Specify the proportion of the failed nozzle density to use to compensate its neighbors. Must be in the range of 0.0 and 1.0. When set to 1.0, the full density of the failed nozzle is used for compensation; when set to 0.0, no compensation is made. |
| Use Compensation Curve | This allows us to use the compensation curve. If it is not selected it will not be present in the screen config. |
| Compensation Curve | A list of 256 entries with values between 0 and 255, specifying the amount of compensation for each gray level. If used with compensation scaling and/or compensation factor, this setting takes the precedence and other settings are ignored. |
The File menu allows you to save or export the media with the settings you select (without performing any press characterization steps). You can then add the SMD into SPC for printing.
File->Preferences
After choosing your Media Definition preferences, navigate to File->Preferences to set how your test charts are generated and define measurement settings.
- Color Measurement - select your Scanning Device and set your Dot Gain preferences.
- Units - choose between Inches or Millimeters.
- Target Dimensions - controls the size of test charts and copy count and auto-print.
- PrintFlat - Configure PrintFlat operation.
Characterization
Once you are satisfied with your settings, you can start customizing drop behavior using the Drop Level Mixing Pane.
Before proceeding, ensure that you Enable External Control in SPC.
