BabelColor CT&A is a collection of tools specifically designed for color translation, measurement, & analysis. Tools are grouped by theme in individually managed windows. Here is a short description of each window.

RGB vs RGB: A bidirectional RGB color-space translator and comparator tool. This tool accepts manually entered L*a*b* and RGB inputs; it does not require a color measurement instrument, although an instrument can be used to input data (instruments purchased separately).

All other tools need spectral data in order to provide results; these tools are
What's New
Version 4.0.0:
  • Toolbar window : The tools can now be accessed with new a top-level window which contains: a toolbar, controls to select a measuring instrument, and status lights for the features supported by the connected instrument (measurement modes, measurement conditions, spectral tools compatibility).
  • Separate tools windows.
    • One or more tool can be opened and used at any given time.
    • Simply click on a window and make a measurement by pressing the i1Pro or i1Pro 2 button, even if different measurement modes are selected in each window.
    • The Main screen of previous CT&A versions is now called the RGB vs RGB tool. This tool opens in a separate window, like the other spectral tools.
  • Added support for the X-Rite i1Pro 2 spectrophotometer.
    • This instrument is used in the 'RGB vs RGB' tool and in all spectral tools.
    • Supported models: i1Pro 2 M0/M1/M2, i1Pro 2 M2 only.
    • Supports the M0, M1, and M2 measurements mode for reflectance measurements.
    • Supports X-Rite’s XRGA calibration standard for reflectance measurements.
    • The i1Pro 2 can be used in CT&A on a PowerPC Mac with the older i1Pro driver; in this configuration, the i1Pro 2 behaves as an i1Pro. The new i1Pro 2 features are available only in conjunction with the new i1Pro 2 driver, which requires an Intel Mac with OS X 10.5.8+.
  • i1Pro and i1Pro 2.
    • Both the older i1Pro and the new i1Pro 2 drivers are provided. The i1Pro2 driver is XRGA compliant and the older driver is NOT XRGA compliant. The new driver is referred to in CT&A as i1Pro / i1Pro 2 (XRGA); the older driver is referred to as i1Pro / i1Pro 2 (non-XRGA). You can thus make measurements with your instruments with or without XRGA calibration.
    • Calibration with the ‘i1Pro / i1Pro 2 (XRGA)’ driver always require that the instrument be positioned on its white calibration tile, even for measurement modes other than reflectance.
  • Added support for the X-Rite i1Display Pro colorimeter.
    • This instrument is used in the RGB vs RGB tool (and not in the spectral tools).
    • Supported models : i1Display Pro hardware sold by X-Rite (i.e. the retail version, part #EODIS3-XR). Generic models sold by other companies (third parties, or OEM, part #EODIS-OEM) should also be compatible. At this time we cannot say if we will support or not custom models sold by other companies since separate agreements with these parties may be required. More specific info will be provided as new models are released. CT&A can load and assign calibration matrices (contained in X-Rite Emissive Display Reference (EDR) files) specifically designed for various display technologies, and which provide improved measurement accuracy. Eight EDR files are supplied, including ones for OLED and Plasma displays; additional files could be added in the future without a need to reinstall CT&A.
    • Select between two measurement speeds.
    • Note : On Mac, OS X 10.5+ is required (Mac Intel tested, PowerPC TBD).
  • FluoCheck tools : Added a set of tools to measure the effect of substrate fluorescence on measured colors. FluoCheck tools provide numerical data on the stability of a color under the M0, M1, and M2 Measurement Conditions as defined in ISO 13655. A Fluorescence Index (FI) is obtained by measuring a color using either M0 (i.e. Ill-A) or M1 (i.e. D50), and M2 (i.e. UV-cut), and computing the color difference between the two measurements. When two colors are compared, a Fluorescence Metamerism Index (FMI) is obtained by using the M2 measurements of the two colors, and either the M0 or M1 measurements (a different FMI is computed relative to M0 and M1).
    • An i1Pro 2 which supports the M0/M1/M2 measurement conditions is required to be able to use the FluoCheck tools. Density, Graph, and Metamerism Index tools : In reflectance mode, and if using an i1Pro 2 which support the M0/M1/M2 measurement conditions, you can now select the measurement condition applicable to the measured data.
  • RAL Design tool : In reflectance mode, and if using an i1Pro 2 which support the M0/M1/M2 measurement conditions, you will now obtain the RAL DESIGN measurement for all these measurement conditions.
  • Whiteness tools : If using an i1Pro 2 which support the M0/M1/M2 measurement conditions, you can now obtain the fluorescence value by using the measurements corresponding to the M0 and M2 measurement conditions, without the need for an external UV filter.
  • Preferences : You can now select between Bradford or CIECAT02 as the Chromatic Adaptation Transform (CAT) to be used for space conversion in the 'RGB vs RGB' and 'MI' tools, and to compute display colors.
Improvements:
  • RGB vs RGB tool (the Main screen of previous CT&A versions) :
    • Entering data with an instrument is now done with dedicated controls which appear in the window whenever the 'L*a*b* / L*u*v* input' checkbox is selected. Each side, Space #1 and Space #2, can be set to use different measurement modes.
    • This window has a dedicated menu that regroups the functions which are dedicated to this tool. This window also has three dedicated icons on the toolbar, with two of these that can be used to open data tables and change some graphics on the chromaticity diagram.
    • Custom RGB space dialog : This dialog can also be called from the RGB space selection menu in Space #1 and Space #2. Improved data entry feedback in the dialog. The other dialog parameters and the graphics are updated dynamically as you enter the values.
    • The 'Bradford matrices' tables has been replaced by 'CAT matrices' so that both Bradford and CIECAT02 matrices can be inspected and copied.
  • Density tools : The density standards now clearly correspond to those of ISO 5-3. Changing the density status no longer requires deleting previous measurements; the previous measurements are now recomputed according to the selected status.
  • ISO 3664+ tools : Improved accuracy for MI (ISO 23603 / CIE S 012) and CRI (CIE 13; also computed in the Graph and Metamerism Index tools).
  • Metamerism Index tools : Patches are not completely surrounded by a thin black border; this enables better discrimination for alike colors.
  • Improved matching between the displayed colors on the various tools for different combinations of illuminants and CAT. Whenever feasible, a measured color is shown as it would appear under the selected illuminant (as in a virtual light booth).
  • Measuring instruments : Instrument detection and connection is more robust and user-friendly.
  • Emission measurements : The program now shows the White Point luminance and CCT in the toolbar window when making an calibration in emission mode. The program now better manages the device used for emission calibration (LEFT, RIGHT, or OTHER display). Default values are assigned if there is a problem measuring the White Point.
  • Help manual : Simplified Table of Contents structure.
Version 4.0.0:
  • Toolbar window : The tools can now be accessed with new a top-level window which contains: a toolbar, controls to select a measuring instrument, and status lights for the features supported by the connected instrument (measurement modes, measurement conditions, spectral tools compatibility).
  • Separate tools windows.
    • One or more tool can be opened more...

BabelColor CT&A is a collection of tools specifically designed for color translation, measurement, & analysis. Tools are grouped by theme in individually managed windows. Here is a short description of each window.

RGB vs RGB: A bidirectional RGB color-space translator and comparator tool. This tool accepts manually entered L*a*b* and RGB inputs; it does not require a color measurement instrument, although an instrument can be used to input data (instruments purchased separately).

All other tools need spectral data in order to provide results; these tools are collectively called spectral tools. Except for the FluoCheck tools, all spectral tools accept inputs from an i1Pro or i1Pro 2 spectrophotometer, manufactured by X-Rite; the FluoCheck tools requires an i1Pro 2.

Density: A full featured densitometer which can measure reflection density, dot area, apparent trap, print contrast, hue error, grayness, and saturation.

FluoCheck: The FluoCheck tools provide numerical data on the color stability of one or two samples under the M0, M1, and M2 measurement conditions as defined in ISO 13655.

Graph: The Graph tools enable you to compare two spectrums and perform simple spectral math operations between them (add, subtract, average, multiply). Measurements can be taken in reflectance, emission, ambient, and flash modes.

ISO 3664+: The ISO 3664+ tools can be used to evaluate the viewing conditions for prints, transparencies, and color monitors, as per ISO 3664, with additional flexibility in setting the individual goals.

Metamerism Index (MI): The MI tools provide numerical data on the color stability of a single sample (color inconstancy) or of a pair of samples (metamerism) under various illuminants.

RAL Design: This tool is used to obtain the color of a measured sample in RAL Design notation.

Whiteness: The Whiteness tools are designed to measure the whiteness, brightness, fluorescence, and opacity of printing papers.

For photographers, press operators, graphic and Web designers, product and textile designers, scientists, hobbyists.
