The Canon PF-10 print head high-precision print heads are manufactured by utilizing the latest semiconductor manufacturing technology to provide an integrated nozzle design. The Canon ink ejection technology achieves size uniformity of 4pl micro fine droplet and droplet placement accuracy. FINE achieves the essential elements for large format printing with high quality such as 2400 x 1200 dpi high-resolution, smoother graduation, and reduction of graininess. At the same time, its high-drive frequency also contributes to high-speed printing.
