Question

When migrating from Nexus RIP to Imaging Engine, what changes to screening technologies will I see?

Answer

Screen Dots

There are a number of screening technologies available in Nexus, some of which are legacy technologies inherited from old systems. Paragon screens will be available in Imaging Engine, but the older legacy screens will no longer be available. Full details are shown in the following table:

Family / Screen

Available in Imaging Engine 14.1

Notes

Paragon Euclidean

Yes

 

Paragon Diamond 35

Yes

 

Paragon Ellipse 35

Yes

 

Paragon Concentric

Yes

Concentric screens for Imaging Engine are not available as a standard dot with options in the workflow, but can instead be created in ScreenManager. The dot created in ScreenManager is still based on the Paragon Round dot, and is equivalent to the Concentric V2 dot in Nexus.

Paragon Round

Yes
only for offset angles

Available since v14.0.1 (Assembly 2)

In Nexus, Paragon Round was primarily targeted at Flexo printing, and uses “identical-dot highlights”. This could cause banding in highlights. Imaging Engine will no longer use this feature but will be able to produce much smoother highlights.
Only the Paragon Round with offset angles is available in Imaging Engine. For flexo angles we advise to use the Esko Circular dot. See documentation on help.esko for more information: Paragon_Screens_in_Imaging_Engine.pdf

Paragon Organic

Yes

In addition to the standard Nexus options, Imaging Engine also includes an Organic 30 screen. Paragon Organic is now called "Organic V2” with a short name “O”.

ABSNominal

No

Paragon or classic Esko screens can be used instead:

  • Round: Paragon Euclidean or Round Fogra can be used instead
  • Elliptical: Paragon Elliptical or Elliptical (E)

CQS

No

Paragon or classic Esko screens can be used instead:

  • Round - Circular Euclidean (C) or Paragon Round (when available)
  • Euclidean - Round Fogra (R) or Paragon Euclidean
  • Square - Square (S)
  • Elliptical30 or Elliptical40 can be replaced by Elliptical (E) or Paragon Elliptical
  • Elliptical10 or Elliptical20 for this degree of eccentricity, one of the Eccentric dots might make a good alternative.

There is no equivalent of the CQS noise parameter which is available in Nexus. This was developed for multiple-beam devices such as the CDI, but there are more advanced solutions for this now. Classic Esko screens are recommended for output to the CDI, such as Circular(C) or Round Fogra (R)

PCC

No

Paragon or classic Esko screens can be used instead:

  • Round - Circular Euclidean (C) or Paragon Round (when available)
  • Euclidean - Round Fogra (R) or Paragon Euclidean
  • Elliptical - Elliptical (E) or Paragon Elliptical 

FM

Yes

Available since Imaging Engine 14.1 (July 2015)
Is available in the Imaging Engine ticket as an FM dot (like Monet dot). For more info, see the document FM screening in Imaging Engine

Esko

Yes

All screens available through Esko, Esko+7.5 and Esko-7.5 will also be available in Imaging Engine. This includes any custom screens as well as the classic screens, as long as they are saved to the standard locate from ScreenManager.

HD Flexo

Yes

All HD Flexo screens are available as long as they are saved to the standard location from the HD Flexo Screens utility.

Screen modifiers

With the Screen family and dots there are a number of options to modify the screen to get better results with particular printing processes. Many of these do have equivalents in Imaging Engine, but options do differ and they are not controlled in the same way:

Feature

Available in Imaging Engine

Notes

Rosette Style

Yes

Available as a preference rather than a workflow option

Seamless

Yes in 14.1

Available in Imaging Engine 14.1

PlateCell CellCentred

Yes

Not available as a workflow option. Instead, PlateCell/Cell Centred options are available in ScreenManager and can be used to make custom screens. These options are still in pre-release.

Hybrid

Yes

Not available as a workflow option. Instead, hybrid features are now available in ScreenManager as a new AutoBlend transition method. This method is very similar to Nexus hybrid and gives improved results

AutoBlend is in pre-release.

Screen angles

The available angles and rulings for Paragon Screens in Imaging Engine are the same as in Nexus. You can choose to work with the standard angle convention which is same as Nexus, or the Esko Normalized angle convention used in FlexRip.

Types of Screens supported in Imaging Engine:

  1. How can I find the "PAREUC → Paragon Euclidean" screen for flexo?, I'm trying to find it on my system but I have only the offset screen, IE user manual (pag 24) indicates this screen is available for offset and flexo but I can't find it for flexo, thanks
