Breakthrough in Inkjet Printing Technology: Green Revolution of Micro Piezoelectric and Cold Printing TechnologyInkjet printing technology has gone through two major technological routes of thermal foaming and micro piezoelectricity competition, among which Epson PrecisionCore technology achieves sub micron level precision control through MEMS technology, becoming the preferred solution for industrial applications. 1. Principle of Micro Piezoelectric Technology: Precision Jet Driven by Mechanical Drive Unlike thermal foaming technology that relies on ink vaporization, micro piezoelectric printheads achieve ink droplet ejection through the inverse piezoelectric effect of piezoelectric ceramics. The Epson MACH print head uses a multi-layer piezoelectric device to complete the voltage loading of 1280 nozzles in 0.1 seconds, resulting in an ink droplet ejection frequency of 50kHz. The core innovation lies in the meniscus control technology, which controls the deviation of ink droplet flight within ± 1.5 μ m through a closed-loop feedback system, ensuring natural color transition at a resolution of 1440 × 1440dpi. 2. Smart Droplet Transformation Technology (VSDT): Collaborative Control of Multi sized Droplets VSDT technology can spray 1.5-22pl six level ink droplets by adjusting the voltage waveform. When printing highlight areas, the system automatically selects 1.5pl droplets to ensure that the color transition error is below Δ E=2; When filling the dark areas, switch to 22pl large ink droplets and increase the printing speed to 25 pages per minute. This technology achieves an ink utilization rate of 92% for photo grade printing, saving 30% ink compared to traditional techniques. 3. Heat Free cold printing technology: dual improvement of energy efficiency and lifespan Cold printing technology abandons the fixer heating module, allowing the printer to go from sleep to ready state in just 6 seconds. The Canon G series models optimize the ink formula by reducing the ink drying temperature from 85 ℃ to room temperature, and use high-density print heads to achieve a single color text printing energy consumption of 0.5W/page. Actual test data shows that cold printing technology extends the lifespan of printer components to 200000 pages and reduces maintenance costs by 65%. 4. Industrial application expansion: from advertising printing to 3D printing The Epson SureColor P20580 large format printer is equipped with PrecisionCore Micro TFP chip and supports a 12 color ink system, achieving a color accuracy of Δ E<1.5 in the field of advertising printing. More noteworthy is that the combination of micro piezoelectric technology and photo cured resin has given rise to a new type of 3D printing solution. The SLA Jet device developed by a certain research institution accurately controls resin dripping through a micro piezoelectric print head, increasing the printing speed to 500mm 3/h, which is three times more efficient than traditional DLP technology. |
