In this article, you will learn which minimum hardware and software-specific requirements must be met for installation, setup and efficient use of the Workflow. However, the minimum requirements should be adjusted according to the requirements and needs of the user. Please discuss these topics with Durst Customer Service in advance.
The hardware requirements for label printing, corrugated board printing, textile and large format printing can vary greatly. For example, we recommend at least 8 CPU cores for label printing with variable data, whereas 4 CPU cores are sufficient for controlling large format printers, since fewer parallel processes will be needed. The hardware requirements listed here are only a rough guideline for a configuration that will get you up and running.
As with any other software, however, the following principle applies: more powerful hardware means shorter processing times. However, this principle cannot be arbitrarily scaled upwards, because increasing investments in hardware do not always directly relate to performance gains.
The minimum requirements for Workflow operation are as described below.
1. Server Platform
The hardware requirements for the server depend largely on the print jobs to be processed in terms of size, speed, color and resolution.
The following information outlines the absolute minimum configuration:
- Intel CPU (i7, Xeon) with at least 4 cores (8 cores for VDP)
- 256 GB SSD or larger for the main drive
- 1 TB or larger for the storage drive
- 16 GB RAM (32 GB for VDP) or more
In many cases it is also possible to use a virtual server (VMware or similar software).
The following operating systems have been tested and approved for the operation of the Workflow Server:
- Windows Server 2008R2 64bit
- Windows Server 2012R2
- Windows 7 Professional 64bit
- Windows 8
- Windows 10
For more information, see the System Requirements section.
Workflow data should be backed up on a regular basis, preferably daily. The following directories and files should be included in a your backup protocol:
Table 1: An overview of the directories to be backed up on the Workflow Server
|Program Directory and Configuration data||C:\Program Files\PPD
|Workflow Data||D:\PMS_DATA (D: could be another Drive letter)
Before backing up, be sure to proceed as follows:
First stop the
PPD-PostGreSQL services. These services must be started in reverse order after the backup is complete. If this is not possible, a »dump« of the database must be made before a backup is made. There is one caveat, this can lead to inconsistencies between the PMS database and management of the PMS file when restoring a backup.
For more information, see the Backup and Recovery article.
3. Antivirus Software
The use of Antivirus Software is explicitly recommended. However, in some cases performance may be impeded by Antivirus Software, therefore we recommend that you make an exception for the following paths (usually under D:\PMS_DATA\) from the real-time scan:
C:\Program Files\PPD may also need to be excluded.
For more information, see the section Setting Exceptions.
4. Workflow Client
Basically, the Workflow can be operated on all end devices (PC, notebook, tablet, smartphone ...) that have a modern browser. Since the Workflow is a browser-based software solution, no particular hardware requirements are placed on the client. What is important is that a current version of the Google Chrome browser should be installed.
In addition to installing the browser, you should install the following programs on the workstation - when available for the respective device.
PDF Reader – since we are only processing PDF files at the moment, we also recommend the installation of a PDF-Reader that meets industry requirements. The current version of Acrobat Reader – or the full version Adobe Acrobat DC – are probably the most suitable software packages currently available.
callas pdfToolbox – If you would like to create individual test and correction profiles, you will also need pdfToolbox from callas software. A test version with which you can create, import and export test and correction profiles as well as open PDF files can be downloaded directly from callas Software. Test and correction profiles can be exported from pdfToolbox and then imported and applied in the Workflow.
5. Adobe Illustrator
If you also want to use the Adobe Illustrator Plug-In, it is necessary to install the latest version of Adobe Illustrator. It must be noted that this increases the hardware and operating system requirements for the client accordingly.
For the optional Adobe Illustrator Workflow Plug-In – available for the Create and Create+ versions – the following requirements must be met:
- Windows 7, 64Bit and upwards
- MAC OS 10.10 Yosemite and upwards
Supported Adobe Illustrator versions:
- Adobe Illustrator CC 2015.3
- Adobe Illustrator CC 2017
- Adobe Illustrator CC 2018
- Adobe Illustrator CC 2019
- Adobe Illustrator CC 2020
An installer of the Plug-In is offered for the last four versions of Adobe Illustrator. The installer will install the Plug-In for all Illustrator versions currently installed on the client.
The installation files for the Plug-In will be updated on the Workflow server or stored in the folder
C:\Programs\PPD\PlugIn each time the Workflow is installed and updated. From there, the installers can be copied to the client and installed. Before you update Adobe Illustrator or the Plug-In, please check if our Illustrator Plug-In is compatible with your version of Adobe Illustrator.
Newer Illustrator Versions
Prepress Digital will provide an update of the Plug-In as soon as new versions of Adobe Illustrator are released.
Before installing a new Illustrator version, please make sure that it is on our approved versions list.
Further information can be found in the Plug-Ins chapter.
6. Measurement Device
Each Substrate must be spectrally measured in order to create color profiles to describe the color range of the machine, ink, print and substrate combination. In order to generate the required measurement data, measuring devices must be checked for compatibility. The following measurement devices are currently supported by the Workflow:
- Barbieri Spectro Swing
- Barbieri Spectro LFP Series 1, 2 and 3
- Barbieri Spectro LFP qb
- Barbieri Spectro Pad
- X-Rite i1Pro
- Konica Minolta FD9
- Konica Minolta CM 2300D
Make sure that the latest firmware version from the manufacturer is installed on the measurement device. For the latest firmware, please contact the dealer who sold you the device or check the manufacturers website for details.
Further information can be found in the chapter Measuring Devices.
7. Cutting Devices
If cutting information is needed for subsequent plotters or laser cutters, the Workflow must be familiar with the protocol for controlling the cutting device. Various cutting devices and laser cutters ranging from Zünd, Bullmer, Esko, Sei and Spartanics can be controlled by the Workflow. Whether a cutting device can be controlled or not depends primarily on the software used for the cutting device and the associated modes of operation - i.e., inline or offline.
Always check in advance whether your cutting device is supported by the Workflow in conjunction with the software used. The integration of further or newer versions of cutting devices can generally be made available very quickly if the corresponding manufacturer specification is provided.
Further information can be found in the chapter Cutters.
8. Printer Software version
To ensure trouble-free operation of the Workflow, we recommend that you keep your printer's software up to date. Clarify the installation of your current Durst printer software with customer service in advance.
The ability to control printers from other manufacturers is constantly being expanded. Please direct inquiries regarding support for other printing systems directly to Prepress Digital. The contact details can be found in the article Contact.
