Gravure-Printing for processing organic materials
PV Material and devices processing Equipment
With gravure printing , the images etched on the surface of a metal plate or cylinder produce recesses or depressions which are filled with ink and the raised (non-printing) portions of the plate or cylinder are wiped or scraped free of ink leaving the ink only in the recesses. Flexible substrates are pressed against the inked plate or cylinder and the image is transferred to the substrate Gravure printing has numerous advantages for the field of printed electronics, where it is already playing an important role: organic light emitting diodes (OLED)?for displays and lighting , UHF RFID label antennas are realized by this useful technique and it could also excel in transistors, circuits and high resolution electrical interconnection. Certainly, solar cells could be a sizable market, and work is being conducted on the university and research center levels.
