We often run short runs of high end art books on iGen while a large offset run is in production in order to meet a public launch or such. The offset and particularly binding process may take some time so the customer will also require say 50 items printed digital on the iGen and bound. On normal jobs the igen operator controls the profiles based on stock types and jobs but in order to match our offset standards we have customised an ISO profile to create a 'press matching' colour profile that we have tested against our XL105, CD74 and our 102 perfectors. Its not perfect but its acceptable for the product and the coour is close but the image quality and screens are no match for 250lpi hybid screening.
Like the previous reply i dont know many operators that will charge bw rate on the igen for a colour job that contains bw. If you want bw we would run that on one of our mono digital printers and they have their own charge/click rate for quoting or run mono on the igen. The iGen would be quoted at colour. It does have the different click charges for bw/colour but if the job was mixed throughout it would all be run as colour, otherwise the collating time and cost would go up significantly. If your book was split simply it could be done, ie pages 1-32 colour, 33 onwards bw.
