Some suggestions to increase the processing and printing speed.


Increasing processing throughput with Automation Engine

When printing a job with Pack Proof (PP) or Content Proofing for Imaging Engine (CPIE), one at a time is processed in Automation Engine. More than one job can be processed by using more Imaging Engine workers. Additional workers can be purchased and added at any time (PP and CPIE come with one default worker!).

More information about workers can be found on the system requirements page of Imaging Engine:
Imaging Engine 18.1 Powered by Adobe® System Requirements

Configuration of the workers is done in Automation Engine. To define the number of workers:

  1. Open the Automation Engine Pilot.
  2. Go to Tools > Configure.
  3. Go to the Imaging Engine node and select an Imaging Engine device.
  4. Choose the number of workers (from the Numbers of workers list).

    The amount of workers depend on the available cores and worker licenses

Increasing processing throughput with Esko Proof Server

By default, one job at a time is processed. Processing multiple jobs is possible by enabling parallel processing as described in this KB: KB242389780: How to activate parallel processing in the Esko Proof Server

Other suggestions to speed up the processing of a job:

  1. Select a proof server workflow
  2. Click the Workflow pane in the property panel
    1. Disable the Preview option (especially when outputting special inks like white and silver you can gain some processing time, e.g. when using a WT7900 printer)
    2. Enable the RIP and print on the fly option
    3. Lower the RIP Resolution

      Lowering the RIP resolution can reduce the print quality. Use the High quality RIP resolution when making a dot proof (in order to have sharp dots), and for a content proof, choose the Fast RIP resolution.

Increasing the printing speed

The printing speed can be increased by lowering the resolution, changing the print mode and / or enabling bi-directional printing.

Bi-directional printing

Select the workflow and enable in the Workflow pane the Print bi-directional option to increase the printing speed. Bi-directional printing will drop ink / print in both directions as opposite of the uni-directional printing which will only drop ink / print from left to right. Note that bi-directional printing can result in a less stable printing behavior, so use it for content proofing and with care for contract proofing.

Resolution and print mode

Resolution and print mode are defined in the EPL file. Here is an example of an EPL with a 1440x1440 resolution and a Quality print mode.

Consult this KB to better understand the relation between RIP resolution, Print resolution and Print mode:

Print resolution and Print mode can't be changed on the fly!

If you want to use another print resolution / print mode then you either have to select another EPL:

or create a new EPL:

General Recommendations

  • 720x1440 is more than enough for a contract proof,
  • 1440x1440 is required when making a dot proof with an lpi higher than 100.
