METHOD FOR DETERMINING INK DROP VELOCITY OF PRINTHEAD

摘要

A method for measuring speed of an ink drop in an ink jet printer is provided to maximize productivity by processing of a one-dimensional line which is different with a conventional method measuring the speed of the ink drop through a second-dimensional plane image processing. A method for measuring speed of an ink drop in an ink jet printer comprises the following steps of: taking a picture of the ink drop sprayed from a printer header; storing a photographed image in a computer; designating a desired part including the ink drop among the stored images to a line; detecting an edge of the ink drop; performing image processing on a selected ink drop; and measuring the speed of the ink drop after image processing.
