Hi, I have a Canon iPF6100 printer and a ColorMunki Photo. The Canon printer has a Photoshop plug-in which enables a 16-bit color flow as opposed to the 8-bit OS driver. If I want to generate a profile to be used with the 16-bit utility, should I execute printarg with the -T option? Similarly, must I use the -t option if I'm using the 8-bit OS driver? Will the -T/-t generate what is called 16-bit/8-bit profiles respectively? I'm not sure what that exactly means but I'm guessing the RGB entries inside the generated ICM profile will be either 16-bit or 8-bit color values. The question is does the printer driver being 8-bit or 16-bit necessitate the usage of the correct type of profile? I can of course experiment to see what happens with which combination but I'd like to learn what really should be happening. Thanks. -tolga
