Latest Patents

Cristina Crespi holds a patent for the "Removal or mitigation of artifacts in incremental printing." This invention addresses the challenge of boundary artifacts by selectively depleting areas at the boundary, specifically in high-color-saturation regions. The patent also introduces printmasking techniques to define depletion regions. Additionally, it explores how different drop-to-pass allocations can be treated as opposites to improve print quality. The invention utilizes a multilayer Shakes mask system, where each mask corresponds to a number of drops to fire, allowing for additive masks based on image content. The high-value mask is strategically used to reduce the number of drops fired, particularly at pixels near boundaries, to prevent artifact-causing boundary coalescence. An adaptive version of the invention measures nonuniformity in area-fill test patterns to define localized depletion bits for high-value masks.
