Abstract

Stock Groups are a mechanism that allows a user to define a number of media that they would like to be treated identically for color processing. A single calibration and characterization is associated with each Stock Group, and all media within the group are processed using those transformations. The user can define a representative, or centerline, stock on which the Stock Groups calibration and characterization are built. This concept allows the user to easily manage a set of stocks as if they were a single stock, and frees them from having to keep track of previous associations, without losing the flexibility of the existing solution.

Using Stock Groups for Color Management

Digital Front Ends (DFEs) for color systems must have a mechanism to tie different color processing to different media types. The most simple color system may have a single set of color transformations that will be used for all media. The most flexible allows the user to associate specific color processing with each defined media.

When a media is calibrated or characterized, the resulting data is manually assigned to the media. The data can also be associated with a number of other media, but the process is manual, and the burden of tracking the associations is left up to the user. There is no way to easily ensure that a group of media be treated with the same color processing, and to ensure that an update to one media in the group propagates to all media in the group.

Stock Groups are a mechanism that allows a user to define a number of media that they would like to be treated identically for color processing. A single calibration and characterization is associated with each Stock Group, and all media within the group are processed using those transformations. The user can define a representative, or centerline, stock on which the Stock Groups calibration and characterization are built. This concept allows the user to easily manage a set of stocks as if they were a single stock, and frees them from having to keep track of previous associations, without losing the flexibility of the existing solution.
