摘要： Preferably, test-patterns print on separate, multiple print-medium cards, each including a ramp with colors graded along a certain direction—and, superimposed on the ramp, a candidate add-on colorant. Ramps preferably are printed in so-called “customer colors”, common in snapshots and particularly snapshot regions that include sky. Positions or amounts of the candidate add-on colorant canvass a likely range of values that optimize camouflaging or suppression of a banding artifact (due to seams in the pagewide array) that is extended along the same certain direction. For each seam and each “customer color” used, an operator holds up several cards for comparison, selecting the best one to three. Operators thus can evaluate candidate colorant patterns in context of many different tones of the sky and other customer colors. Preferably banding suppression is integrated with linearization: at each seam a series of linearization tables is smoothly interpolated between measurement-based tables for adjacent inkjet dice.

摘要： Disclosed is a new printing apparatus and process for inkjet printers which incorporates spectral modeling of ink mixing and the technology of halftoning in device-independent color space. In addition no colormap building or color mapping processing is necessary, because color correction is conducted in device-independent space and is built into the halftoning process. also disclosed is an automatic self-calibration by the printer without user intervention or user preferences by using an optical sensing unit on the printer. The procedure corrects for print cartridge to print cartridge variance, and variance of print cartridges over time and also provides for faster processing of color images.

摘要： High speed optical modulators can be made of a reverse biased lateral PN diode formed in a silicon rib optical waveguide disposed on a SOI or other silicon based substrate. A PN junction is formed at the boundary of the P and N doped regions. The depletion region at the PN junction overlaps with the center of a guided optical mode propagating through the waveguide. Electrically modulating a reverse biased lateral PN diode causes a phase shift in an optical wave propagating through the waveguide. Prior art forward biased PN and PIN diode modulators have been relatively low speed devices.

摘要： A halftoning technique is disclosed which uses look-up tables to identify a combination of color ink drops (device states) to be printed by an inkjet printer. The look-up tables are indexed by a particular color to be reproduced. An error is also output by the look-up tables reflecting the difference between the indexing tone level and the printed color spot. The error is applied in a halftoning process to neighboring pixels. A plurality of look-up tables is used, and one of the look-up tables is selected for a particular medium (e.g., glossy paper, plain paper) to be printed upon. In this manner, the number and combination of ink drops can be optimize for a particular type of medium. In one embodiment, six different color inks are used by the printer.
