It explains why focal variation, oblique marking angles, geometric distortion, surface roughness, coating inconsistency, and heat accumulation can reduce barcode readability. The article then outlines core solutions, including dynamic focus control, rotary and multi-axis motion, software-based distortion compensation,..."}
