摘要:
A print inspection device is provided with a camera for picking-up an image of a substrate to be processed after a paste is printed on the substrate through a mask sheet by a printer, a measured value calculating a measured value of a printed paste area based on the picked-up image of the substrate, a setting means for setting a standard range for working state judgment of the area, and a comparing and judging means for comparing the measured value with the standard range and for judging whether the printer is in a normal working state or not depending on whether the measured value is in the standard range or not. The setting means sets the standard range to a less paste amount side for a predetermined period of time after the mark sheet is cleaned up than for other periods of time.
