Thanks for your reply Graeme. As mentioned earlier, the 'Online Profiler' allows for 3 different presets for perceptual gamut mapping: ---Quote--- "In our Online Profiler you can find three different presets for the gamut mapping. They represent the source gamuts. 1. Default: Weighted averaging of sRGB, AppleRGB, and GenericRGB (Apple) with a sRGB TRC 2. Enhanced: Weighted averaging of AdobeRGB and ECI RGB v2 with a L* TRC 3. Big: Pro Photo RGB with a L* TRC ---End quote--- From a conceptual point of view, wouldn't it be better to implement a curve in such profiles, that mimics the behavior of the printer, instead of an L* curve?
