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!).
Other suggestions to speed up the processing of a job:
Select a proof server workflow
Click the Workflow pane in the property panel
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)
Enable the RIP and print on the fly option
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.
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.
