1. An integrated circuit for a replaceable print component associated with a print material of a predetermined color, the integrated circuit comprising
a memory storing print data including wrappers and packets to construct a plurality of color maps, and
interface contacts to, when connected to a printer controller, in response to a request from the printer controller, communicate the print data to the printer controller,
the print data including
a plurality of color map wrappers, different color map wrappers corresponding to different color maps, each color map wrapper including
a first level tag indicating a media for a color map, and
a color map recipe to construct the color map, the recipe identifying second level wrappers including a DCT (discrete cosine transform) wrapper and a residue wrapper, each, by at least one locator included in the recipe;
a plurality of DCT wrappers, each DCT wrapper comprising
at least one second level tag corresponding to the locator, and
wrapping around a DCT packet of the color map; and
a plurality of residue wrappers, each residue wrapper comprising
at least one second level tag corresponding to the locator, and
wrapping around a residue packet of the color map; wherein
each DCT packet is associated with a corresponding residue packet through the color map recipe.
