ArtPro has the concept of true object-based screening, where each object can have a discreet set of screening parameters applied to it. Traditionally, ArtPro customers have tended to send files to Nexus RIP in order to RIP them. To ensure that the objects’ screening parameters are provided to the RIP in an optimum manner, ArtPro has a ‘Nexus Extended’ tab in its screening palette. This is intended to work with Nexus PDF RIP, and exposes the RIP’s screening features to the user in a straightforward manner. For customers of ArtPro and Nexus, this is the obvious and best choice for object-based screening, and the one that has been used in most cases.

When ‘Esko’ screens were made available to Nexus and ArtPro customers, the method that was used to specify the relevant screening options for these screens was to set them in ArtPro’s ‘PostScript’ screening tab. This sets the mnemonic of the selected screen as custom screening code, which is interpreted by the RIP as being a request for the relevant Esko screen. When customers wish to RIP an ArtPro file that contains objects that are set to use Esko screens, they need to use this method to define the screening parameters for both Nexus RIP and FlexRip.

For reference, the mnemonics for the Paragon screens are:

Paragon Elliptical35ParEll35

Paragon Roundis available since Imaging Engine 14.0.1
Organic (Stochastic)O


Since version 14.1 (July 2015), there is an extra tab called ‘Imaging Engine Screening’ in ArtPro 14.1. Using this tab, users will be able to select screens and dot-gain curves that are installed on their Automation Engine Server, and set up object-based screening for Imaging Engine.

The following can be done in ArtPro 14.1:

  1. Start from a Nexus Extended screen set (or from a PS (Esko) screen set).

    While that screen set is selected, switch to the Imaging Engine tab. All settings that are supported by Imaging Engine will be automatically taken over like ruling, angles etc. and also dot shape if it is supported by Imaging Engine.

  2. Start fresh - without Automation Engine connection (no server information in Preferences > Servers > Automation Engine).

    Just enter your own dot shape etc. or select from the list. You can also start typing, it will auto-fill if it finds a match in the list. This is a default list provided by ArtPro, pretty much the same list as the Esko screens provided on the PS tab.

  3. Start fresh - with Automation Engine connection (server information in Preferences > Servers > Automation Engine, with green status).

    Now you can still enter your own dot shape, but even easier is to select it from the list (you can also start typing, it will auto-fill if it finds a match in the list). In this case the list is the list of dot shapes available on the Automation Engine.
    You can notice that you are looking at the Automation Engine list with a green icon next to the dot shapes combo box.

Situation before 14.1

ArtPro 14.0.1, which was released in January, already provides a partial solution. When you have an ArtPro file with Nexus Extended screening, and you do an Export to Normalized PDF from ArtPro 14.0.1, Imaging Engine will already be able to read that screening information. Provided of course that the screening is of a type that is supported by Imaging Engine.

Supported dot shapes are:

Within the Paragon family:  

  • Euclidian  (in Imaging Engine: PAREUC)
  • Diamond35 (in Imaging Engine: PARDIA35)
  • Ellipse35 (in Imaging Engine: PARELL35)
  • Round (in Imaging Engine: PARROUND)

Within the Paragon Organic family: all subtypes (in Imaging Engine: O)
