the print material is black or suitable for monochrome printing;
the second level wrappers include a plurality of CBAT (Coefficient Bit Assignment Table) wrappers, each CBAT wrapper identified in the associated recipe by the locator;
each CBAT wrapper comprising at least one second level tag corresponding to the locator, and wrapping around a CBAT packet configured to be decoded by the printer controller to decode the DCT packet associated with the CBAT packet by the recipe.
12. The integrated circuit of claim 1 wherein the packets are to be decoded or combined to construct the color map by the printer controller based on a set of predetermined building instructions on the printer, and
each recipe comprises a build operator that refers to the build instructions corresponding to the recipe.
13. The integrated circuit of claim 1 wherein a plurality of different second level wrappers and associated packets, associated with different color maps but having the same packet type, is grouped into a continuous string of data, the memory structure storing different groups of different packet types.
14. The integrated circuit of claim 1 wherein p 1 the packets are to be decoded separately to construct the color maps out of the combination of different packets, and
the wrappers and packets associated with the plurality of color maps stored on the memory are compressed as a single data container, to be decompressed as a data single container.
15. The integrated circuit of claim 1 wherein the wrappers and packets are to be decompressed as a single data container using a single dictionary.
16. The integrated circuit of claim 1 wherein the first and second level tags specify a table type.
17. The integrated circuit of claim 1 wherein the second level wrappers comprise properties comprising a color channel.
18. A print material cartridge comprising the integrated circuit of claim 1 and a reservoir containing the print material associated with the color map.
19. A print cartridge memory structure storing a single compressed data container including a plurality of color maps, the data container, when decompressed by a printer controller, comprising
a plurality of first level wrappers, each first level wrapper associated with a color map of the plurality of color maps and including
at least one characteristic to identify a corresponding color map, and
a recipe to define and locate packets for constructing the color map, the recipe having at least one locator for each second level wrapper that pertains to one of the packets;
