Technical considerations when designing and building an Industrial ink jet printer

摘要

The Task: You have been chosen to design your company's newest inkjet printer.rnThe Challenge: The printer must have increased productivity with high image quality. How do you calculate the best approach and quantifying your design choices?rnThis paper will discuss the important inputs required for the design process and steps systems designers should consider when undertaking such an initiative. Including:rn1. Printer resolution defined in dots per inch (dpi)rn2. Ink type, solvent, UV, Aqueous or oil based for examplern3. Number of colors requiredrn4. Productivity measured in m~2/hrrnFrom these considerations, calculations to predict the drop mass output per jet and the jetting frequency and carriage speed required to build up an image will be introduced.rnThe goal by the end of the paper will be to identify:rn5. The most suitable Dimatix printhead for the intended printer/ applicationrn6. The speed of the printhead carriage assembly or the media transport under the printheadsrn7. The jetting frequency of the printheadsrn8. The number of heads required per color.
