Today I release the fourth alpha version of the Next Generation Toolbox. This version features support for CMYK color space and color profiles for graphic export.
If you have a previous alpha version of XL Toolbox NG installed, you can update via “Check for updates”.
See the new changelog.
A word on color management
As noted elsewhere, Excel itself does not know about color management, so any color profiles used during graphic export can only be an approximation. (Maybe I’ll add support for screen color profiles later.) If your publisher requests embedded profiles, the Toolbox lets you do it.
Exporting in CMYK colorspace requires the use of color management profiles. Otherwise the conversion from RGB would not work.
