摘要:
A preferred embodiment reproduces an image by receiving an input contone array of M contone data values. The contone data values may lie within a range from 1 to N. The embodiment includes comparing each contone data value to an array of M sets of pattern look-up tables to generate an array of M pattern values. M may be a number of one or more. Each pattern value in the array of M pattern values may be decoded to a corresponding K by L multi-pixel pattern of binary data. The binary data is rendered by a reprographic device.
