Thanks. This option is greyed out when using pdf/x3 (but shows 'printer').
When using another type of pdf (1.3 1.4 or 1.5) the prepress option does
not allow to specify the icc profile to be used as intent.
Will the profile defined in color management for printer be used ?

Also, how can I check that the saved PDF does indeed only contain CMYK
objects and no RGB ? (Using tools available on linux)
