Latest Patents

Sascha De Peña holds a patent for the "Removal or mitigation of artifacts in incremental printing." This invention focuses on lowering boundary artifacts by selectively depleting at a boundary, specifically in high-color-saturation areas. The patent also introduces printmasking techniques that define depletion regions. Additionally, it explores how different drop-to-pass allocations can be treated as oppositely signed. The invention utilizes a multilayer Shakes mask system, where each mask represents a number of drops to fire, and these masks are additive based on image content. The high-value mask is employed in opposition to reduce the number of drops fired, particularly at pixels near boundaries, to negate artifact-causing boundary coalescence. An adaptive version of the invention measures nonuniformity in an area-fill test pattern, using the results to define localized depletion bits for high-value masks.
