The following are the minimum system requirements for Imaging Engine 21.03 Powered by Adobe®. Exceeding these requirements will in most cases lead to a performance increase. Running Imaging Engine Powered by Adobe® on a system that does not meet these requirements is not supported.

Information on additional Imaging Engine Tools

The following tools can also be installed on the same system:

  • Curve Pilot (which can include PressSync Pilot)
  • HDFlexo Screens
  • Screen Manager
  • Bitmap Viewer (64-bit)

You can also install these tools on a separate system, see Additional Tools for Imaging Engine 21.03 Powered by Adobe® System Requirements for the minimum system requirements for these tools.

In the 18.x releases, Print Control Wizard was a part of Curve Pilot. Since version 20, the Print Control Wizard is integrated in the Color Pilot. Color Pilot can be installed on the same system or on a separate system. For system requirements and a list of supported Spectrophotometers, refer: Color Pilot 21.03 System Requirements.

Minimum requirements

Minimum System Requirements for Imaging Engine 21.03 Powered by Adobe®
Processor type and speed

Only 64-bit Intel® compatible processor, minimal four logical cores per worker + four logical cores for the OS (so eight logical cores in case of one worker).

Intel® CPU

We've only tested on Intel® CPU's and not on "non-Intel" CPU's. But they are assumed to be compatible.

Number of workers

The number of workers you can configure for Imaging Engine is determined by the license you have and by the number of cores/processors on the server. So even if you have a license for four workers, but only two cores, you can configure only two workers (Even four cores is below the minimal requirement for one worker).

"logical cores" means:

  • same as number of physical cores when hyperthreading is disabled
  • 2 x physical cores when hyperthreading is enabled

Enabling Hyperthreading can increase the performance, but it could also cause problems when you are at the limit of using all cores. In this case, we advise to disable hyperthreading.

Clock speed: minimum 2 GHz - higher is better (a 3 GHz CPU will typically rip 50% faster than an equivalent 2 GHz CPU)

Minimum 8 GB for the OS + 8 GB RAM per worker (e.g. 16 GB RAM in case of 1 worker - 40 GB RAM in case of 4 workers).

For more info about memory limitations in Windows operating systems, please consult this table.

Hard disk

  • A dedicated defragmented hard disk.
  • An NTFS volume is required.
  • The installation takes up 20 GB of disk space.
  • At least 100 GB per worker for storage of temporary data is advised.
  • Fast hard disk: SSD if possible
  • A back-up solution is strongly advised.
Network100/1000 Base-T Ethernet, TCP/IP v4 protocol. TCP/IP v6 protocol is not supported.
Graphics and videoMinimum 1280 x 1024 screen resolution, true color depth.
  • VMware ESX version
  • Microsoft Hyper-V

Hardware connections, including dongles, proofers, spectrophotometers and others may work, but are not supported. Customers should verify hardware support through their virtualization support channels.

File servers

All Esko applications running on Windows OS can use data that is available on network shares. These shares need to be on Windows file servers. We recommend to use Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2, Windows Server 2016 or Windows Server 2019 as file server.

Only Windows file servers are supported. Mac OS X or Unix/Linux (CIFS/SMB or NFS) data servers for instance are not supported (including many Network Attached Storage units).


Imaging Engine and Automation Engine

Imaging Engine and Automation Engine must run exactly the same version (e.g. 21.03).

Imaging Engine and Pack Proof (including the Esko Proof Server)

Pack Proof is a version of Imaging Engine that is sold specifically for proofing only solutions. Imaging Engine 21.03 is compatible with both Pack Proof 20.1 (Esko Proof Server 18) and Pack Proof 21.03 (Esko Proof Server 20).

One server or different servers?

Imaging Engine and Automation Engine

We advise to install Automation Engine and Imaging Engine on separate machines. Check the system requirements for both products.

Imaging Engine and Imaging Engine Pilot

Imaging Engine Pilot is actually a lightweight Automation Engine with two processing channels. It can be run on the same machine as Imaging Engine, but the properties of the system should at least provide the sum of what both products require with regard to the amount of processor cores and RAM.  

Imaging Engine and the Esko Proof Server (part of Pack Proof)

In case of heavy load on the Esko Proof Server, we advise to install the Esko Proof Server on a separate machine. If you decide to install both the Esko Proof Server and the Imaging Engine on the same machine, then first check the Imaging Engine system requirements to make sure minimum two extra cores (and preferably four) are available for the Esko Proof Server in addition to what Imaging Engine needs.

Proof Server connectivity problems

To avoid connectivity issues, we advise to install the Proof Server on the same PC as the Automation Engine Server (Additionally you must execute workaround 2 as described in this article: KB172026546: FlexProofE/PackProof - Proof Server Application stops after start up

Additional Supported Operating Systems for Imaging Engine for CDI

Imaging Engine for CDI is a version of Imaging Engine that is sold specifically along with the CDI and is designed just for that purpose. The Imaging Engine for CDI can drive only one device using LEN format, processing only one job concurrently. Because Imaging Engine for CDI is a more restricted version, it can be supported on the "workstation" versions of Windows that are listed below. The full Imaging Engine Server is only supported on the "server" versions of Windows that are listed above.
