Linearization

♦ Tweak Linearization
Desired Target Tab (Figure 1) Use the Desired Target tab to view and edit the density targets for a linearization calibration. Name lists all existing Media Models. + opens a dialog for adding a New media model and selecting Basic (recommended) or Advanced (Non-ICC Workflow). - deletes existing Media Models. Save saves the currently selected Media Model. Save as allows to save or rename a Media Model. Advanced Readings option displays measurements from an Advanced Media Model. Edit - Select the color you want to edit from the drop-down menu. Then click in the chart to edit the values. View As - Select either Density or Effective Dot Area from the drop-down menu to view. NOTE: The Scale button will change to Dot Gain when viewing as Effective Dot Area. Chart Range - The Chart Range value controls the maximum density (y axis) value shown on the graph. Adjust this by clicking the up or down arrows. NFactor - The N-Factor value controls the density of the mid-tones for a color channel. The default NFactor setting is 2 (recommended), and has a range of .5 to 5.0. Scale - The Scale value evenly scales the density values for the color channel. The Scale function does not remember the previous settings, in other words, whenever Scale is used, the current value is considered a 100% scaling, regardless of whether the color channel was previously scaled. Dot Gain - The Dot Gain is the value for how much the dot expands when it hits the paper. Click this button to set the value from -49 to 49. Reset returns settings to previous value. Swatch Measurement Tab (Figure 2) The Swatch Measurements tab shows the density measurements that were read from the linearization swatch. The measurement values are shown per color under Patch Measurements; as well as plotted on the graph. Chart Range - The Chart Range value controls the maximum density (y axis) value shown on the graph. Adjust this by clicking the up or down arrows. Paper - The Paper area shows the density readings of the media itself (with no ink applied). Linearization Table Tab (Figure 3) The Linearization Table tab shows you the linearization in graphical form. The Linearization (Table) is a result of the desired targets, swatch measurements, and linearization options (variance and smoothing). You may not change the linearization table directly. Click Analyze to check for errors within the Linearization table. Build Clicking Build finalizes the Tweak Linearization step. Use the linearization build options to determine how a linearization is created from the density readings. Options (Figure 4) Variance - Use the Variance setting to specify how linear the linearization should be. Set the slider to Linear (Variance = 0), Non-Linear (Variance = 100), or anywhere in between. The default and recommended setting for Variance is 10. Smoothing - Use the Smoothing slider to even out spikes in the linearization data. The range of the Smoothing setting is from 0 to 11. Smoothing should be used when significant spikes exists in the density readings; even after re-reading the linearization swatch. Setting a Smoothing value above 4 may cause the density readings to become inaccurate, resulting in poor color reproduction when printing. For instructions on generating G7 advanced calibrations (available in version X10.1 or newer), see Advanced Grayscale G7 Calibration.
