Abstract
A method and apparatus for rendering using band by band depth adjustment preferably begins by recording extents for each object on a page. An extent indicates where color or non-color ink begins and ends on a page. Extent blocks are then created. An extent block is comprised of at least one extent of the same ink type. Next, a band is created for each extent block. The bit depth for each band is adjusted based upon the ink type associated with each extent block. If the ink is black or white, a band having a bit depth of one is created. If the ink is color or gray scale, the bit depth is adjusted to the proper depth for that band. An object or portion of an object is then rendered into a band having the necessary bit depth for that object.
