You can select different paper types from Gutenprint to find out, which is 
most saturated without bleeding colours. With the uncorrected mode you get 
a basic calibration for standard papers. If thats bright enough, you are 
probably done.
Otherwise you'd have to hand edit the channel sliders or curves, which is 
not convenient. A proper tool to handle this step automatically is missing.
