Concentric screens on Nexus was setup and used from Nexus Expose tickets.
In Imaging Engine, screens are used (selected) from an Expose ticket. However, as setup of some screens are not part of the base screens, it is done from a dedicated screening application (Screen Manager, HD Flexo). So, not only the way of setup is changed but also the screen format.
Nexus customers having Concentric screens, will get Screen Manager 14 with a permanent license!
Screen Manager 14 is part of the Imaging Engine 14 products installer. So, when you have the license activated, the Screen Manager application will be installed next to your Imaging Engine rip.

Click the + button to make a new screen.
Enter a name, e.g.: Concentric.
Select your original dot - Paragon, e.g.; Paragon round.
Click the Concentric tab and switch on Concentric screening.
Define the following settings for your Concentric:
Select the Pixel Area radio button for Screen levels Sort On.
In the Ruling dependency drop-down menu, select not ruling dependent option.
Uncheck the Restrict to Flexo Angles only checkbox.
Uncheck the Restrict ruling from checkbox.
Define the resolution.
When all settings are done, click the Save button. This will create your Concentric screen in the bg_data_screens_v020 folder (can take a while because the screentiles are saved on your harddisk).
When finished, you can use the Concentric screen in the Imaging Engine tickets. Go to the Separations tab and select the SCR03 --> Concentric in the Dot field.
