Visual Representation By Matrix Printers TRIZ Cases

A printing apparatus adjusts nozzle position and voltage in real time to control droplet impact paths on uneven surfaces.

A predefined mask filters print signals to selectively block marking material application across multiple print pixels per image pixel.

A print data generating unit converts image data into multiple values using a halftone process that ensures zero value inclusion.

A liquid discharge apparatus controls ink dot ratios to improve image quality and reduce banding artifacts in printed output.

A controlling device determines main scanning direction based on target line image data to optimize ink discharge.

A printing control device selects color conversion tables based on scanning path position data to ensure uniform ink deposition during multipass operations.

Segmenting image data sets controls overlapping dot amounts during multi-pass recording, suppressing density variations while maintaining low granularity.

A liquid droplet discharging control device adjusts nozzle output to compensate for defective nozzles.

A weighted average processing unit calculates pixel values using attribute-based coefficients within a modular image processing device.

Segmenting memory into reversible image and fixed pattern regions prevents forgery while maintaining display versatility.

Printer locking units prevent damage from forced opening attempts by displaying locked state notifications on the operation panel.
