Abstract
A row-interleaved printing method for use in phase change ink jet printers which minimizes appearance abnormalities when printing solid geometric shapes; minimizes the horizontal 'banding-effect' caused by cross-talk between ink jets when all jets are activated; and minimize the 'seaming effect' caused by paper step mechanisms when different velocity profiles are used during printing.
