For a dual-line 1200dpi thick film thermal printhead, the rendered dots are of elliptic shape, with aspect ratio of 1:1.5, due to the constraint of a smaller pitch in 1200dpi and the minimum nib line width required during nib line formation. This is one area for image quality improvement. Characteristics of conventional single-layer nib lines of different line width are studied. Based on the experimental result, a new formation approach of two-layer nib line structure is studied and tested to achieve the goal of producing an ideal round dot shape with aspect ratio of 1:1.
