AI Technical Summary
Existing technologies cannot fully account for the density dependence of splicing characteristics in multi-printhead printers, resulting in the inability to completely correct alignment errors between inkjet modules and producing visible artifacts.
By printing test images on a printing medium, specific density and feature patterns are generated using adjacent jetting modules with overlapping nozzles. After digital analysis, the splicing error correction value is determined and adapted to production image data to reduce splicing errors across tracks and within tracks.
It achieves accurate stitching error correction that is insensitive to defects in the injection module, reduces visible artifacts in the image, and provides an improved density-dependent correction method.
