Before you go to [G7® Grayscale Correction] step, you will need to add or edit your workflow first.

1. Click the [Reports and Tools] icon on the toolbar (Figure 1).
2. Select the [Customize Workflows] button (Figure 1).
3. Click the [Add] or [Edit] button for a new or existing workflow, and choose [Yes] (ICC-Based) or [No] (Non ICC-Based).
4. In the [Workflow Name] box, type a name.
5. Click [Workflow Features], and enable the options that you want available. You also can select whether or not you want to print a test image after each step (Figure 2). (NOTE: All features are checked in default settings.)
6. Click the stop button ( ) and choose [Yes] to close the “Workflow Editor” window.

 

Now you can create or edit a profile using this workflow.

Profile as usual up through the Ink Limit step. The next step is the [G7® Grayscale Correction] step.

 

In the [G7® Grayscale Correction] step;

1. Click [Print Swatch]. This opens “Print Swatch-G7 Neutral Print Density Curves” window (Figure 3).

2. [Use “G7 Native CMY”] allows for print-mode specific variations of 300% gray balance to be accounted for. This is especially important when a print mode has a significantly different color for 300% CMY than for offset printing. This setting is enabled by default (Figure 4).

3. In this dialog, there is [P2P Swatch selection]. This option has 2 selections: Standard P2P51 Swatch (default), Less Cyan (better for solvent printers). (Figure 4).

(NOTE: Default settings in the “Print Swatch” dialog are recommended for most inkjet printers. However, for solvent printers, it is recommended to use [Less Cyan (better for solvent printers)] setting.

 

Starting in version 18.5, you can set the desired number of [Control Points:] for the G7® Grayscale Correction (Figure 4). .

• 1% increments

• 5% increments

• 10% increments

 

[Highlight and shadow weighted (default)] is the default setting

 

NOTE: Higher numbers of control points can potentially increase the accuracy of the grayscale correction, but it is generally printer-dependent. Lower amounts of control points can be useful if the printer is already fairly linear.

 

4. Select the appropriate number of control points for your printer.

NOTE: The control points selected in this step will also be used if an iteration is done on the G7® Verification step.

 

5. Once the P2P swatch has been printed, click the [Read Swatch] button and read in the swatch (Figure 5).

6 After reading the P2P swatch, G7® Grayscale correction curves are automatically built. Click [Next] button to proceed to [G7® Grayscale Verification] step.

Alternatively, to import G7 Grayscale correction curves from　third-party software, click the expansion arrow ( ) in　the white circle step, and click the [Import... ] button (Figure 6).

1. Select a CGATS file (.txt extension) with the third party G7 curves and click [OK] (Figure 7)..
2. The imported curves are set as default, and the step receives a green check mark (Figure 8).
3. Click next button ( ) to proceed to [G7 Grayscale Verification] step.
