Spot colors in halftone proofs

OpenColor DotProof profiles (MXD profiles) allow up to 15 color channels. After creating a main (usually CMYK) DotProof profile, you can either add job specific spot colors and create profile variants OR add a spot color library for dynamic DotProof profiling, which will automatically be used if you publish the project for a certain proofing condition. 

Printing and measuring of test charts after adding the inks is not required. Even when the main MXD profile will be optimized later, those changes will be automatically carried over to the dependent profiles, without any further work from your side.

How to add spot colors 

• Dynamic profiling: Add a spot color library and publish the project with an iterated MXD profile (with at least two iterations).
• Static profiling: Click the Add button next to the profile name to add one or more inks to the profile. You can choose inks from all spot colors used in the current project. If you have a spot color library, you need to add the spot colors as project inks first.
  
  GMG OpenColor then calculates a profile variant with the additional inks, for example "PANTONE 2368 U" in the screenshot:
  

Static profiles: Dependency between the main profile and derived profile variants:

• Recalculations and optimizations applied to the main profile are automatically applied to all profiles derived from it. (Manual profile corrections are applied only to the edited profile.)
• You cannot iterate dependent profile variants.
• You can create a copy of a profile variant and make it independent, including the ability to edit and iterate it independently and to derive new profile variants from it.
