You need to gang two advertisement cards (from two existing Prinergy jobs) onto one press sheet. To manage last minute edits, the page data for each card is to be aliased from the existing Prinergy source jobs.
Using page aliases lets you better manage many types of edits. If a change is made to a source page, the page alias associated with the source page is automatically updated with the change.

Important: Page aliases can be created using Preps imposition software, Pandora software, and other supported imposition file types. For the purposes of this activity, Preps imposition software will be used.

Note: For the purposes of this activity, tasks 1 to 6 are included to create the source pages that will be aliased. In a realistic prepress environment, these jobs would already exist on your Prinergy system.
Page aliases are helpful if ganging or combining multiple jobs or parts of a job onto a single press sheet. A page alias is essentially a pointer to an original source page in another job. If the original source page changes, the page alias will be updated automatically.

Identifying source pages and page aliases

If you use Preps to gang Prinergy pages, page aliases—instead of copies—are created in the ganged job to assist in managing edits.
Page aliases are links to original source pages, and provide many benefits compared to copies. Page aliases are created when a populated imposition is imported into a Prinergy job from Preps.

Benefits of page aliases

Page aliases provide the following benefits:

  • Page aliases save file space because pages are not duplicated.
  • Page edits are easily managed—for example:
    • If a page's contents are updated, when output, the alias automatically picks up the latest updates of the original. There's no need to duplicate the update content to the alias.
      Note: This benefit applies to simple updates (text/object changes). Other changes, such as color conversions or geometry changes could invalidate the existing ganged imposition. In this case, you would need to re-create the imposition.
    • If the approval status of a page changes, it is reflected in both locations.
  • History entries about ganged pages are logged in both the source job and the ganged job.
  • Source and aliased job and page names are cross-referenced in the History entries and Get Info dialog box.
  • On refine, each page is tagged so that if you copy it to a different location before ganging it, the source job and source page can still be identified when it is imported into Prinergy in a ganged layout.
  • Custom fields can be added to page aliases.
    Note: A detailed report of ganged press sheet usage by source job is available with Prinergy Business Link software.
    Important: Be aware that making changes to a page alias also affects the source page.

Limitations of page aliases

Page aliases are not available for:

  • Pages that are re-refined after ganging—If you re-refine a page after it has been ganged, but before the gang layout has been imported, the ganged layout will fail to import into Prinergy. Therefore, ensure that page content is stable before ganging.

Some page changes might invalidate an existing ganged layout, such as number of inks or geometry changes. In this case, you'll likely need to re-build your gang imposition.

  • Other imposition software—If you use imposition software other than Preps to gang pages, page aliases might not be created. Using non-Preps applications to build gang jobs and aliases has not been tested. The pages assigned to the impositions may be registered as input files, and may require a refine.
  • Impositions populated within Prinergy—If, without using Preps, you add more than one instance of a page to an imposition within Prinergy, the pages are duplicated in the imposition.

Use an external imposition application

In this activity, rather than using Signature Selection, we are going to use the Use External Imposition Application option in the New Imposition dialog box, and create the imposition in Preps.
The Preps Full Access option (licensed), enables you to start Preps from within Prinergy Workshop, and to have full functionality of Preps Pro.
This option allows you to create and edit Preps templates, which are automatically imported into Prinergy when you print to an Adobe Job Ticket or a JDF file from Preps. Essentially, the license allows for the automatic transfer of files between the Preps imposition software and a Prinergy Workshop job.
Full access Preps Pro can be made available via Prinergy's Floating License Manager (FLIM) so that you do not need a dongle for every workstation that runs Preps. For example, when you buy two copies of this Preps software for your Prinergy system, Preps can be used at any Prinergy client as long as the total number of copies in use at one time does not exceed two.

Preps software

Preps software is included with Prinergy.

Configure the imposition applications

Before starting to work with Preps, make sure that the imposition applications have been configured in Prinergy via Tools > Configure Imposition Applications. The way the imposition applications have been configured has a direct result in the imposition choices and/or results you will get in the activities in this lesson.

Note that both line items are pointing to the same location.

If the Application type is Preps Pro Floating License, you will get a blank page workflow in Preps. You will get a page count, but will not see the actual files.
If the Application type is Preps Ganging, you will get the actual pages from the job, but there are special circumstances:

  1. There must be a page set defined.
  2. There must be pages assigned to that page set.

If condition 2 is not met, Prinergy will not even launch Preps! Also, if you select Preps Ganging and then combine with pages from another job (like page aliasing), unless you change the settings in the Choose Process Template dialog box from Import > ImportAll to Import > ImportAllReplaceImposition, the file will fail on import.
