A variety of printing techniques are being utilized in the field of manufacturing. In this volume, printing technology as a production technology will be explained.

(1) Printing technology as a production technology in manufacturing

1. Pattern drawing printing technology

・	Resolution of PC printed characters are expressed in bpi (bits per inch = dot density per 1 inch). It indicates that printed characters would be in higher definition as this dpi value increases.
・	It can be said that pattern drawing printing technology is constituted with positioning technology, high resolution technology, and ink material technology.

Pattern drawing technology = Positioning technology + High resolution technology + Ink material technology

・	The characteristics of the printing technology above have matched with manufacturing technology aiming to achieve high added values, and the printing technology is being utilized in a variety of high-tech industries.
・	Application examples

	（1）	Solder flux printing
	（2）	Printing of viscous materials such as resistive materials, etc.
	（3）	Adhesive printing for partial bonding
	（4）	Resist pattern forming for microlens array forming

2. (Overcoat) Printing technology that covers wide areas in uniform thickness coatings

・	t can be said that the (Overcoat) printing technology that can cover wide areas with uniform thickness coating is composed of highly precise print coating thickness control technology and ink materials technology.
・	The highly precise print coating thickness control techniques are utilized for forming of insulating films for semiconductors and organic films for LCDs. Required film thickness precision is in the order of dozens of nanometers (nm=1/1000μm).

Printing technology to coat with uniform film thickness = Highly precise print film thickness control technology + Ink materials technology

・	Application examples

	（1）	Semiconductor insulating film forming
	（2）	Adhesive pre-process primer application
	（3）	Thin film (insulation film, orientation film) forming of organic multi-layer thin film structures for liquid crystal displays.
