This document defines an exchange format for target input values, colour and process control data relating output targets for printers of all types (and the associated metadata necessary for its proper interpretation) in electronic form. This document includes the use of a CustomResource element within the CXF framework to define a minimum set of data for exchange and identify the data as being part of the ISO 12642 series. If this same framework is used for another defined target, provision is made for that use as well.
