August 14, 2012 -- Printed electronics is a set of printing methods used to create electronic circuits, sensors, devices, and various electronics products. Printing is emerging as a technology that can replace traditional photolithography processes for electronics manufacturing, reducing costly material use, very complex processes, and expensive equipment. Printing enables direct patterning of desired materials on the desired location without complex processes, and production is cleaner and more productive, according to Displaybank, an IHS analyst business.

Printing devices can lead the creation of new industries through technology fusion.
Printed electronics can be classified as substrate and printing material-related technology: various technologies that allow functional materials to be deposited at a desired position, equipments and parts that can run these technologies, and methodologies.
Printed electronics process technology includes material technologies of printed electronics inks such as conductive inks, insulating materials, and metal nano-inks, new printing process technologies such as inkjet printing, µ-contact printing, and imprinting to print materials, and various equipment technologies to support these.
