Summary: | PROBLEM TO BE SOLVED: To provide an ink jet droplet observation method and device which can easily observe the states of ink droplets discharged from nozzles of an ink jet head in a short time and perform parameter setting of a new head.SOLUTION: A droplet observation method uses a device which has a photographing section 150 for photographing flight states of ink droplets 300 discharged from nozzles of an ink jet head 500, a light source section 160, and an image synthetic section 190 which superposes and synthesizes a plurality of sheets of photographed images of the ink droplets while synchronizing each discharge state of each ink droplet by the photographing section and the light source section. A plurality of sheets of images indicating the discharge states of the droplets discharged from a plurality of nozzles of the ink jet head are synchronized and photographed. The photographed images are superposed so as to acquire a synthetic image of the ink droplets. State observation of the ink droplets discharged from the plurality of nozzles of the ink jet head or a plurality of ink droplet sizes are observed with the synthetic image at one time.SELECTED DRAWING: Figure 5
【課題】インクジェットヘッドのノズルから吐出するインク液滴の状態を短時間で簡易的に観察でき、新規ヘッドのパラメータ設定も可能なインクジェット液滴観察方法及び装置を提供する。【解決手段】インクジェットヘッド500のノズルから吐出されたインク液滴300の飛翔状態を撮影する撮影部150及び光源部160と、これらによって各インク液滴の吐出状態を同期させながら複数枚撮影されたインク液滴の画像を重ね合わせて合成する画像合成部190を有した装置を用いた液滴観察方法であり、インクジェットヘッドの複数個のノズルから吐出される液滴の吐出状態を示す画像を複数枚同期して撮影し、この撮影画像を重ね合わせてインク液滴の合成画像を取得し、合成画像によりインクジェットヘッドの複数のノズルから吐出されたインク液滴の状態観察又は複数のインク液滴サイズを一度に観察する。【選択図】図5 |
