In GMG OpenColor, you can create proof profiles with White for prototype proofing in GMG ColorProof. You simply define the purpose of the White ink in the Proofing Condition of the project.
|None||The proof profile will not contain a White channel.|
The proof profile will contain a White channel, for printers with white ink capabilities. You can map a white spot color to this channel in GMG ColorProof. You can also use the channel in GMG ColorProof to print an undercoat, mainly used on clear film.
You can tune the opacity of the White ink with the White Ink Level. It defines how much ink will be applied for the undercoat or spot color channel when the corresponding image channel is set to 100% in GMG ColorProof. That means, if the channel is set to 30% in the proof job and the White Ink Level is set to 50%, a total of 15% White will be printed.
The minimum value of the White Ink Level is 10%, as there is no substantial difference between 1% and 10%. The White Ink Level affects only white channels mapped to MXN/MXD in GMG ColorProof. Image channels mapped to a db3 spot color or a custom spot color will not be affected.
|For Metallic Ink Simulation||
Select this option if you want to simulate metallic inks by printing standard inks on a metallic foil on an Epson SureColor SC-S80600. You will be able to simulate any metallic color such as PANTONE® Metallics or any custom color.
Less metallic colors are simulated by printing a white undercoat. By applying the right amount of white ink, you can control the metallic effect and shininess specifically for each color in the Start Profile Calculation dialog box. Metallic Gloss Level (All Inks) defines the default value for all colors in the profile.

|For Opaque Ink Simulation||
Select this option if you want to simulate metallic substrate printing by printing standard inks on a metallic foil on an Epson SureColor SC-S80600.
The opacity of a printed color is simulated by printing a white undercoat. The higher the opacity will be in the target print production, the more white is printed. You can define the opacity specifically for each color in the Start Profile Calculation dialog box. Opacity Level (All Inks) defines the default value for all colors in the profile.
You can also define the Metallic Gloss Level (Substrate). For example, if the substrate you want to simulate is really shiny, you will set it to 100%. If the substrate has a more matte appearance, you can lower the value accordingly.

Once you have a profile, you can change the settings easily without recalculation.
- Under Finalize, click the Edit button on the right side of the profile.
- Click the Adjust White, Metallic Gloss Level, or Adjust Opacity tabbed page, depending on the White Undercoat mode selected under Proofing Condition.
- Adjust the values and click the Save button.
