Droplet discharge device and droplet discharge method

摘要

A printer includes a control section that is capable of executing a first process for forming an image on a sheet by discharging ink droplets from a liquid ejection head on the basis of image data and a second process for forming, on the sheet, a test pattern for determination of a shift in ink droplet adhesion position by discharging droplets on the basis of test data. The control section executes the second process in a state in which a print gap between the liquid ejection head and a support is longer than the shortest adjustable print gap.

1. A droplet discharge device comprising:
a discharging section having a discharge opening that is capable of discharging liquid in the form of droplets; a supporting member that is capable of supporting a medium onto which the droplets discharged from the discharge opening adhere; a gap adjusting section that is capable of adjusting a print gap between the discharging section and the supporting member; and a control section that is capable of executing a first process for forming an image on the medium by discharging droplets from the discharging section on the basis of image data and a second process for forming, on the medium, a test pattern for determination of a shift in droplet adhesion position by discharging droplets on the basis of test data, the control section executing the second process in a state in which the print gap is longer than the shortest print gap adjustable by the gap adjusting section, wherein the control section causes a speed of discharge of the droplets from the discharge opening in the second process to be lower than that in the first process.
