METHOD FOR MANUFACTURING NOZZLE TIPS

Document Type and Number:

WIPO Patent Application WO/2013/088506

Kind Code:

A1

Abstract:

The present invention is a method for manufacturing nozzle tips having a step in which discharge port lines are formed by emitting light beams by using a mask having a pattern that forms a discharge port line pattern for one nozzle tip by connecting discharge port line patterns with a connection part. The method for manufacturing nozzle tips is characterized in that the mask is configured such that the absolute value of the off-axis degree of telecentricity of the light beams emitted by the discharge ports closest to the connection part is smaller than that of the discharge ports furthest from the connection part in the array direction of the discharge ports of the discharge port lines.
