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

Automate DeviceLink Profile Color Transformaion

ZePrA Smart Color Server can be integrated into an existing workflow for immediate results. ZePrA’s easy-to-use interface simplifies the process of creating custom DeviceLinks with SmartLink for any workflow.

Advantages of ZePrA at a glance:

  • Simple, clearly structured user prompting and setup
  • Multi-threading for extraordinarily high speed file processing.
  • Superior color conversion and transformation.
  • Outstanding support for Spot Color Conversion with reporting.
  • Correction of gradation curves for process and spot colors
  • Supports integration with Enfocus Switch workflow automation.

 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.

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 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 files can be verified with the help of an integrated soft proof without requiring any additional third-party tools.

With the help of the Configurations window, users can manually define any combination of color management workflows needed. Individual configurations can be saved and applied to any hot folder, or modified for other color management needs.

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 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 (GRACol, FOGRA, SNAP, etc.), and that ink 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.

Managing Spot Color Libraries

Zepra_SpotColor Illus..png

Select the tool Spot Color Libraries from the sidebar to access the window Manage Spot Colors. To measure spot colors from color fans, print samples or Corporate Identity Colors use a spectral photometer or enter them manually. It is also possible to import existing color tables with spot colors. Supported formats are Named Color ICC profiles, Photoshop ACO color tables, text files in CGATS format or CXF files. The color values can be present as Lab or spectral data. Spectral measurement data is preferable as it permits the best internal calculation.

The upper part of the dialog Library shows all available libraries and the number of spot colors of a library. Additionally, the revision number and expiry date of PantoneLIVE libraries is displayed (with the PantoneLIVE icon). Login if necessary to update the libraries.

After double-clicking on the selected library the spot colors will be shown in the lower part of the window. In order to improve the performance – especially with extensive and many libraries – spot colors will only be available when they are actually used in the processing of jobs or by double-clicking on a library.

Notes: PantoneLIVE libraries are protected and in ZePrA they can not be edited, extended or removed. The PantoneLIVE dialog for importing Pantone spot colors into ZePrA is available directly in the dialog Spot Color Libraries.


Tip: Adobe Photoshop users can export color tables with LAB color values form Photoshop in the form of ACO files. X-Rite Pantone Color Manager program users can export tables as Named Color ICC profiles or CXF files which will have the actual LAB values but not the spectral values.

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 form.
  • 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.
