[ECI-EN] Uncoated paper in Sheetfed enviroment

I dont know were to go At our printphop we have Heidelberg sheetfed presses Two 8c 70x100 One 8c 50x70 one 5c 70x100 We are thinking of changing our colour management workflow into ISO standard the ISOcoated_v2_300_eci Will probebly work fine but the ISOuncoated We have a problem with that profile, it´s set to total ink coverage of 320% even more than the coated one These days we have around 260% of total ink coverage on uncoated paper in sheetfeed environment This is a problem we have if we should make it easy for our client to start using ISO standard Do any have any solution or idea for future ISO profiles for sheetfed presses Regards Morgan Axelsson
