I use a rather crude system .. that appears to work for me: I created my own 'calibration image', in software, that is made up of 9 x 10 colour and grey scale patches. Each patch also has RGB values printed in one corner (8 bit, 16 bit and %s). When I view this PNG image on my monitor the RGB readout (in Rawstudio for example) matches the values within 1% throughout the range of colours and the colours are 'satisfactory' to my eye (not very scientific). When I print this image I expect to be able to closely match the print to my monitor .. so far, for me, this has worked fairly well.
