Visual Representation By Matrix Printers TRIZ Cases
- Line Width Correction in Printing Systems via Rasterization Resolution
Vector-based line width detection images enable direct correction of printed line widths, resolving inconsistencies caused by varying rasterization methods.
- Visual Noise in Flat Tint Areas of Printed Images
A visual noise module adds dithering patterns to flat tint areas in rasterized image data.
- Inkjet Dot Arrangement Patterns Suppress Joint Streaks
A printing apparatus selects specific dot arrangement patterns based on pixel position and gradation levels to optimize image quality.
- Dynamic Tone Reproduction Curve for Print Streak Reduction
A spatial tone reproduction curve adjusts dynamically using weighted ink usage averages to maintain consistent print quality.
- Printing Apparatus Ink Discharge Control for Gloss Uniformity
A printing apparatus controls ink discharge from preceding and succeeding nozzles to manage resin composition on the medium.
- Inkjet Printing Overlap Stitching for Visual Continuity
A printhead deposits overlapping ink webs using a Y-curve function to vary ink quantity along the track.
- Inkjet Nozzle Defect Detection Using Weighted Thresholds
Weighted threshold calculations differentiate alpha and beta defects in test charts, minimizing false positives without manual assessment.
- Head Control Unit Null Data Transfer for Inkjet Printers
A head control unit transfers null data to an inkjet print head.
- Inkjet Quantization Optimizing Dot Arrangement to Suppress Vibration Irregularities
A quantization method optimizes dot arrangement timing and frequency across pixel columns to minimize dispersion in binary or multivalued image patterns.
