Barcode Printing Pass Control for Resonance-Stable Inkjet Scanning

The patent dynamically adjusts the printing strategy based on the detected barcode pattern. When periodic patterns are detected that could cause resonance, the system switches from one-pass to multi-pass printing, making the printing approach adaptive rather than static. This resolves the contradiction by allowing high-speed one-pass printing for non-critical areas while using slower multi-pass printing only where resonance would occur.

The patent changes the printing parameters (number of passes) based on the detected image content. By analyzing the barcode structure and identifying periodic patterns, the system modifies the printing process parameters to avoid resonance frequencies, thereby maintaining ejection stability while preserving overall productivity through selective application of the multi-pass method.

The patent applies different printing qualities to different regions of the print data. Instead of uniformly applying multi-pass printing to all content, the system performs image analysis to identify specific barcode regions with periodic patterns and applies multi-pass printing only to those localized areas. This resolves the contradiction by maintaining high ejection stability where needed while preserving overall printing speed through selective application.

The patent uses partial action by applying the more reliable but slower multi-pass printing method only to the extent necessary - specifically to barcode regions with periodic patterns that could cause resonance. Non-critical regions are printed using faster one-pass printing, thus achieving sufficient ejection stability without the excessive time cost of applying multi-pass printing universally.

The patent dynamically selects the appropriate printing method based on real-time analysis of the barcode structure. By detecting periodic patterns that would cause resonance and subsequent dot formation errors, the system adaptively switches to multi-pass printing for those specific barcodes, thereby maintaining manufacturing precision without sacrificing overall productivity through universal use of the slower method.

The patent changes the printing process parameters (number of passes) based on the detected barcode characteristics. When periodic patterns are identified that would compromise dot formation accuracy through resonance, the system modifies the printing parameters to use multiple passes, thereby ensuring manufacturing precision is maintained for critical elements while preserving productivity through selective parameter adjustment.
