*When reporting, Maxwell will automatically reconcile any sample color set with your chosen reference set. For instance, if you choose the GRACoL 2006 or FOGRA 39 color references, they are both composed of 1617 color patches as described by the IT8/7-4 color target standard. Any sample color set wil be compared with these selected references when reporting and all color patches shared by both targets will be used to calculate report values. No configuration of target information is necessary for this function. This allows many different target types and orders to be compared in the same report. Old press runs from ten years ago using a small target can be easily compared to today's runs with larger targets.

Patch ''types'' include single ink patches, for instance, so all the Cyan, Magenta, Yellow or Black ONLY patches can be quickly extracted to calculate TVI (dot gain) and other values for tolerancing and graphing.

CHROMiX Maxwell draws on a wide range of technologies. This page summarizes those technologies for those interested in Maxwell's underpinnings or who are working on supporting Maxwell through API communications. Most technologies below are not of CHROMiX construction but a few are.

Color Science

Spectral Data

Colorimetric Data

At this time, XYZ and Lab values in Maxwell are calculated for D50 and 2 degree observer. Emissive colors for displays and illuminants may be based on a non-D50 white point but will be adapted to D50 for color differencing equations in most cases.
Maxwell has the ability to specify and adapt to/from varying white points and we will be exposing more of these capabilities in future upgrades.

CHROMiX SmartTarget™

CHROMiX SmartTarget is patent-pending technology that allows the automatic reconcilliation of color patches between color targets containing different sets of patches in any order.
For SmartTarget to function properly, all measurement files should contain BOTH device values and color or spectral values for each patch. X-Rite ProfileMaker's MeasureTool and ColorPort both create color files of this type by default so if you are using these tools you should have no problems.
SmartTarget aids in the uploading / importing of colors as well as the rapid and reliable extraction of color values from the repository.
