A proposal is made to substitute grey marking materials for colored ones in any highlight or full color electronic imaging system. The substitution would be made at the corresponding image locations where an intermediate level grey signal is desired. The purpose of adding grey is to reliably improve the quality of a given resolution monochrome scanner imaging system by reducing scanning artifacts and improving the information content of the image. This approximates the performance of a higher resolution scanning system without having to actually increase the scan frequency of either the input or output device.
