ColorLogic ZePrA - the Smart Color Server
Automated Ink Optimization and Intelligent Color Conversion

Automated use of first-class ICC and DeviceLink Profiles
Now that DeviceLink profiles have increasingly established themselves for processing digital data for various reproduction methods, ZePrA from ColorLogic offers a solution for automating the color conversion of PDF and pixel files by means of ICC and DeviceLink profiles. 

Advantages of ZePrA at a glance:

  • Simple, clearly structured user prompting and setup
  • Extraordinarily high speed
  • The outstanding quality of color conversion resulting from the use of ColorLogic SmartLink and DeviceLink profile technology
  • The outstanding quality of PDF processing. ColorLogic geared the software to the PDF test files of the Ghent Working Group ( for processing PDF/X files, which are processed faultlessly
  • Linking to Enfocus Switch, and thus to a completely automatable workflow, from data receipt, preflighting and top-class color conversion, all the way to data distribution
  • Correction of gradation curves for process and spot colors

 The easiest way to automate color conversion work is to use a combination of ZePrA and the Standard DeviceLink Profile Sets. This combination allows conversion of data to standard printing conditions without being a color management expert. A few clicks is all it takes, and ZePrA then automatically configures all the necessary hot folders and is instantly ready to process PDF, TIFF and JPEG data for the CMYK, RGB and Grayscale color spaces and spot colors. ZePrA can be configured differently to address the various targets of possible color conversions. Therefore, four different ways to define your queues are available:

  • Normalize to document color space or output intent
  • Normalize and convert colors to new output condition
  • SaveInk or optimize total area coverage
  • Direct color conversion to new output condition

Special features of ZePrA
The combination of ZePrA and ColorLogic DeviceLink profiles is currently the world's simplest and fastest PDF color server when it comes to individual configuration. ZePrA is the first solution to provide full support of the standard tags in ICC DeviceLink profiles and use them to define a workflow. In addition, it is extremely fast.  But ZePrA is not only fast, it also delivers top quality by converting all PDF/X standards (from X-1a to the latest X-4 and X-5n standards). Jobs can easily be monitored in the clearly structured Overview window, which is divided into jobs in progress, pending jobs, and processed jobs. The color quality of the converted file can be verified with the help of an integrated soft proof without requiring any additional third-party tool. ZePrA is, of course, not limited to using the standard profiles. This is just one possible way of creating a workflow.

With the help of the Configurations window, users can manually define any combination of color conversions they need to automate. Individual configurations can be saved and applied to any hot folder, or duplicated and modified for other conversions. There are separate areas for selecting the desired color conversion for every supported color space.


Define Configurations
"Define Configurations" is used to make all the settings relating to the handling of colors and PDF-specific parameters. you can select existing configurations, create new ones, or rename, delete and save any configurations. If you have selected an existing configuration and would like to duplicate it, just add a new name, modify the settings, if required, and save – it's so easy... 

Selectable Levels of High Quality Ink Optimization
Set up workflows to apply specific color conversions and high quality ink savings.  ZePrA provides a range of intelligent Device Link Profiles sets for limiting the total amount of color (TAC) for various printing standards,
e.g. ISO, Fogra, ECI, Ifra, Gravure (PSR), GRACoL, SWOP, SNAP.  

The ColorLogic DeviceLink profiles for ink reduction preserve the separation characteristics while at the same time replacing CMY with black. This leads to far better transformation than classical ICC-based conversion with strong GCR. There are SaveInk profiles for three different intensity levels. The first level optimizes the data for a long, narrow black and is designed to stabilize the printing process and harmonize the separations on a form. The second level targets good ink saving and the best possible printing characteristics. The third level focuses on maximum ink reduction, but presupposes that the press is perfectly set for the respective printing standard, and that the densities are not varied during printing.

In addition, options are available for the targeted handling of spot colors, the definition of PDF-specific settings and, from Version 2.0 on, the new capability to apply correction curves to process and spot color channels with the help of the brand-new Gradations module. 

Gradation curves can later be applied to CMYK and spot color channels. The application of gradation curves completes the process of preparing data for printing. Shortly before going to press, almost every printing process calls for a printing characteristic that is stored in the RIP of the platesetter. This printing characteristic primarily serves to ensure compliance with printing standards and to compensate for imponderables in the printing process, these being brought about by a host of printing parameters, not least also by the substrate and the ink. These printing characteristics can now be directly included in the data to be converted. This function also allows you to make last-minute changes. Working with ZePrA is so easy and so powerful.

There are many applications for ZePrA

Workflows can be configured very flexibly and very simply in ZePrA. The following are some typical applications of ZePrA for automated color management tasks:

  • Digital printers want to make their printing data look similar to offset printing.
  • Printers want to automate the color conversion of data from different prepress suppliers in order to standardize the separations in the print job and harmonize differently separated image files on a forme.
  • Prepress companies have an extensive stock of press-ready legacy copy and want to convert the data to a new printing standard or a different printing process without encountering problems on the press as a result of re-separated data.
  • Printers and print providers can re-separate entire documents with incorrectly or inadequately separated data for the required printing standard or the in-house standard.
  • Printers can reduce the amount of ink used by applying ColorLogic SaveInk profiles.
  • Print providers or printers want to standardize mixed-color files supplied in PDF/X-3 or X-4 format to get CMYK, and possibly a spot color, without disruptive RGB color spaces.
  • Media-independent documents can be converted to different maximum printing color spaces and maintain the color appearance.
  • Printers and print providers want to convert spot colors to CMYK in order to be able to print them in 4C.
  • Printers want to adapt the gradation of spot colors to compensate dot gain.
  • Image agencies want to provide large numbers of untagged image data with a defined profile in automated fashion.
  • Service providers for the packaging printing sector want to separate PDF files automatically via a multi-channel profile (MultiColor ICC profile).

These are just a few workflow scenarios for ZePrA.
