Spot Color Report

Review accuracy of spot color conversion

Spot Color Report

Overview

The spot color report shows the results achieved with a spot color conversion in relation to deltaE00, deltaE76, and the separation into process colors. This allows the accuracy of spot color conversions to be checked before processing or printing, and to determine in advance how ZePrA converts spot colors (e.g. Pantone® or other spot colors).

Procedure

    1. Configurations: Select one or more configurations from the list which contain all settings for the conversion. Only Configurations which have spot color conversion enabled are displayed in the list.
    2. Select a single PDF or image file, a spot color library or multiple files under Source Data.
      PDF or Image File: Select the PDF or pixel image file with spot colors to be processed using the settings of the selected configuration.
      Library: Select the spot color library to be converted using the settings of the selected configuration.
      File List: Add multiple files which will be checked simultaneously.
    3. Select the Sort order.
      Sorts the list according to various criteria. When sorting by Delta E, spot colors with the lowest dE are listed at the top, and the highest dE at the bottom.
    4. Create the report. It can be created in various formats (PDF, XML, Text, CGATS or Color Exchange Format).
      Save: Creates the spot color report and saves it. Optionally, a Preview can be created beforehand.

    Best Configuration: The configuration with the lowest maximum deltaE00 will be automatically determined and listed as Best Configuration on top of the report.

    Overview: The Preview and the spot color PDF report show an Overview and a Best Configuration section that describes how the file(s) were processed with the various user-selectable configurations.

    Process File(s): Selected files can be processed directly from the Spot Color Report window with the best configuration. The files are automatically moved to the Input folder of the corresponding configuration and automatically processed.

    The spot color report shows the results achieved with a spot color conversion in relation to deltaE00, deltaE76, and the separation into process colors.

    Note: When creating the report, all spot color settings made in the Configurations are used, including manual settings and warnings. Colors with warnings are displayed in red deltaE values.

    A table of contents (TOC) in the PDF report file allows easy navigation to the details of each configuration. This is especially helpful in getting directly to the details of the individual configuration results if a spot color library has hundreds or even thousands of spot colors that have been evaluated.

    Features to streamline production

    Different configurations can be set up, for example for printing with the same printer but using different target profiles with CMYK, 5 colors, 6 colors or 7 colors. Then the production PDF file(s) can be checked with all possible color configurations. It may be found that the production PDF file(s) do not need 7C, but are already well suited with a certain set of 5 colors or even CMYK.

    This way, many clicks in digital printing or many plate productions in conventional printing could be saved. After checking the file(s) and determining the best matching configurations, the file(s) can be automatically processed with the configurations having the lowest maximum DeltaE directly from the Spot Color Report dialog.

    Spot Color Report Example: The screenshot shows the preview for processing spot colors with two different configurations. All spot colors found in the PDF file are included. One configuration uses a CMYK target profile and the other a 7C target profile. The report shows that in this case the 7C profile is much better suited for simulating the spot colors of the PDF file.
