PatchTool CUSTOM ILLUMINANTS TOOL

previous previous screenshots home screenshots home next next previous previous screenshots home screenshots home next next
Use this tool to define two (2) Custom Illuminants which can be assigned in any opened file, Compare window, as well as in dialogs which require an illuminant selection (For ex.: Missing Info, Select Compare, Substrate Correction, and Tweak Target). The Custom Illuminants always appear as “Ill-1” and “Ill-2” at the end of the Illuminant selection menus. Spectral data is required to define a Custom Illuminant in PatchTool (i.e. such an illuminant cannot be defined only with XYZ coordinates). However, a Custom Illuminant can be assigned to a file containing only tristimulus data (XYZ, L*a*b*, RGB, etc.). A Custom Illuminant can be measured from within this dialog with an X-Rite i1Pro or i1Pro 2 fitted with an ambient adapter. Illuminant data can also be loaded from a file. The file must be in text format; such files typically have .txt or .csv file extensions. As for the file data structure, a plain text file as described in Appendix A of the PatchTool Help manual is accepted as well as a CGATS file. The spectral data must be defined between 380 and 730 nm or between 400 and 700 nm, in 10 nm increments. The file must contain only one (1) spectrum. Please consult the “Custom Illuminants” section of the PatchTool Help manual for a complete description of this tool’s features.
