  Color Translator & Analyzer (CT&A) for Mac and Windows

  • Version 4.5.2 (November 2015): Maintenance release
    Version 4.5 (December 2014): Color and Tone monitor uniformity as per ISO 12646:2014-Final Draft; Version 4.2 (July 2014): Color Rendering Index tools: CRI, CQS (NIST Color Quality Scale), CRI2012 (nCRI Version 12), GAI (Gamut Area Index), MCRI (Memory CRI)
    (What's new?)
           <-- CT&A on the Microsoft Surface Pro!

    CT&A is a collection of tools specifically designed for Color Translation, measurement, & Analysis. Tools are grouped by theme in individually managed windows; these windows are controlled with a menu or a toolbar window.

    The RGB vs RGB tool is a bidirectional RGB color-space translator and comparator tool. The RGB vs RGB tool accepts manually entered L*a*b* and RGB inputs; it does not require a color measurement instrument although many colorimeters and spectrophotometers can be used to input data (instruments purchased separately; a list of supported instruments is available here).

    All other tools need spectral data in order to provide results; these tools are collectively called spectral tools. The CRI tools can accept input from an i1Pro or i1Pro 2 fitted with am ambient adapter OR from a file (an instrument is NOT required). All other spectral tools require a connected i1Pro or i1Pro 2 spectrophotometer, manufactured by X-Rite (the FluoCheck tools can only use an i1Pro 2).

  PatchTool for Mac and Windows

  • Version 5.0 (October 2015): Join files tool, Edit patch list, Target generation, Assign RGB to display, ...
    (What's new?)

    PatchTool is designed to import, view, edit, measure, compare, average, join, convert, and export color lists in a color-managed environment.

    Import CGATS, CxF1, CxF2, CxF3, text files, and Adobe Swatch Exchange (".ase") files). Extract the colors from a target image. Extract a profile from a file. Open small TIFF files as patches.

    unconstrained display measurements with the Display-Reader tool. Characterize your display with Display-Check using a built-in set of patches, or patches from any opened color list. Supported instruments: X-Rite i1Display Pro, Eye-One
    TM Display, DTP94 (formerly from MonacoOPTIXTM), i1Pro, i1Pro 2; Datacolor Spyder2TM, Spyder3TM, Spyder4TM.

    Use Patch-Reader tool to measure colors in reflectance with an X-Rite i1Pro or i1Pro 2. Select between three measurements modes: unconstrained measurements; a custom chart with user-assigned rows and columns; or a chart defined by an opened file. With the i1Pro 2, you can select the M0/M1/M2 measurement condition as defined in ISO 13655-2009.

    Edit color lists: Move, copy, extract, delete and flip patches; swap two patches.

    Join two or more color lists which are defined by the same color reference data type.

    Process color lists: re-arrange, optimize for target printing, average, compare with statistics, profile conversion, substrate/backing conversion.

    Convert color lists using one or two ICC profiles (Gamut Tools), check if a color list will be clipped by a profile conversion, determine the gamut volume of a profile, and generate fixed pitch color lists.

    Export to CGATS, plain text, or CxF3 file format. Export to CxF3 compliant files used by X-Rite's i1Profiler (see the detailed CxF3 export specs and Application Note AN-10). Export lists as images, to Adobe Swatch Exchange files, or as as color catalogues (Color Decks) to be used within the BabelColor CT&A program.

  DeltaE* for AndroidTM

  • Version 1.0 (March 2012)

    is a tool designed to compute color-differences using industry standard formulas. Compute DeltaE* (DE*) with the CIELAB, CIE94, CIE94-textile, CMC(1:1), CMC(2:1), and CIEDE2000 formulas. This program is designed specifically for the Android OS and can be purchased from the Google play Web site (previously called the Android Market).

PatchTool CxF3 export Application Note

PatchTool can export to generic CxF3 files as well as several CxF3-compliant file types used by X-Rite's i1Profiler. This Application Note presents PatchTool's CxF3 export features while highlighting the differences of the various i1Profiler file formats. Examples are shown for X-Rite's i1Profiler "Measure Chart" and "Profiling" workflows.

PatchTool Extract Target from Image tool

Supported image formats: TIFF RGB, CMYK and L*a*b* (8 bit/16 bit), JPG RGB (8 bit), and PNG RGB (8 bit).
Embedded profiles are recognized and automatically extracted.

CT&A tools for whiteness / brightness / fluorescence / opacity

FluoCheck: The FluoCheck tools are made possible by the capabilities of X-Rite's i1Pro 2 spectrophotometer which supports the M0, M1, and M2 Measurement Conditions as defined in ISO 13655. These tools were devised by BabelColor to rapidly evaluate if a color sample is susceptible to fluorescence and if two samples that match without fluorescence still match when fluorescence is taken under consideration.

Whiteness tools: These tools are specifically designed to measure white paper Whiteness, Brightness, Fluorescence, and Opacity in three clicks of your i1Pro or two clicks of your i1Pro 2 (the instruments must be non-UV-cut model). Since these measurements need to be done on compliant white and black backings, and require a well characterized UV-cut filter for fluorescence measurements if using an i1Pro, we also provide tools to check the compliance of such backings and measure the characteristics of UV-filters (backings and UV-filter not included).


Display-Check is a specialized tool of PatchTool. Use it to check your display calibration or to certify your monitor using the recommendations of Idealliance.

Many popular colorimeters and spectrometers are supported.

Click here for an example of a monitor certification report you can get from PatchTool (converted to a PDF format).

Please download Application Note #4 (AN-4) on the Tutorials page for instructions on on how to get similar data.

Use this tool in association with BabelColor CT&A ISO 3664 tools for complete monitor analysis.
