Hi Jan-Peter, The metadata approach, with the publicly available repository hosted on the ICC site, is established so that there can be a general and universal solution to this long-standing problem. The PPD approach works only in certain environments. In addition, the color selectors are severely limited in the current PPD definition and extending the PPD structure to accommodate the additional color selectors is problematic. The advantage of the metadata approach is that the information is provided in a way that does not depend on which workflow, or which print format, or which operating environment, and then the information can be used in a variety of ways, proprietary or open, in these different situations. This is a good discussion you have started and I too am interested to hear the opinions on this, particularly as the ICC Automated Workflow WG which I chair is leading the metadata work in the ICC.

Currently, it seems to me, that we have following possibilities: 1) PPD colour keywords: The PPD for a given printer must be able, to describe all color relevant driver settings with all parameters (incl. low level driver settings if necessary) an ICC profile will be assigned to a proper parametrized PPD and the PPD will completely set up the color options in the printer driver. 2) Driver settings implemented as metadata-information into the ICC-profile Like with the PPD-workflow, all color relebant printer driver settings are stored as metadata into the ICC-profile. The printer driver must be able to extract this information from the ICC profile and will be completely setup by the ICC-profile itself. 3) serialized driver settings The driver settings are able to be serialized (which optimally able to be exported and imported) The ICC-profile will be associated with the serial ID of the driver setting. It would be interesting to know, which of these ways are preferred by the community.
