hello I'm using 5000k fluorescent tubes in my work area. I read about using custom illuminants when using fluorescent tubes in the colprof documentation. I measured the spectrum using a colormunki photo. Can I use this for my scanner profiles, or only for printers? I'd like my scanned image to look as much as possible as the real thing I scanned. Or do I need to make a custom target (with my custom illumination) and use that to profile my scanner? josvanr
