Problems solved by technology

[0007] Even according to the technical content disclosed in Patent Document 1, this defect cannot be overcome
Furthermore, even if the following method is combined in the technical content disclosed in Patent Document 1, that is, the above-mentioned defects cannot be overcome under the situation of cutting off the power supply after slowing down the conveying speed of the object to be printed.
[0008] In addition, even when the conveyance speed of the object to be printed is higher than the assumed speed, the problem that the stop position may deviate from the target position may occur.

Embodiment Construction

[0040] Hereinafter, a printer 10 and a printing method according to an embodiment of the present invention will be described with reference to FIGS. 1 to 13 . Although the printer of this embodiment is an inkjet printer, the inkjet printer may be an apparatus using any ejection method as long as it is capable of ejecting ink for printing.

[0041] In the following description, the lower side refers to the side on which the printer 10 is installed, and the upper side refers to the side away from the installation side. The direction in which the gantry 21 moves, which will be described later, is referred to as the main scanning direction (X coordinate direction), and the direction perpendicular to the main scanning direction, that is, the direction in which the print object P is conveyed, is referred to as the sub-scanning direction. Further, the side where the object to be printed P is fed will be referred to as the paper feeding side (rear end side), and the side where the obj...

Abstract

The present invention provides a printer (10) and printing method. The printer (10) comprises a storage unit (116), for storing reference information relating to reference stop characteristics of the motor (31); a measurement control unit (111), for measuring actual stop characteristics of the motor (31) to control as well as drive the motor (31); a corrected output calculating unit (115), for comparing the actual stop characteristics with the reference stop characteristics when the measurement control device controls driving of the motor, so as to calculate a corrected output of the stop characteristics which is the standard one; a corrected output assistant unit, for outputting the corrected output power to the motor so that a stop condition of stopping the transport object is satisfied. Thus, even though the stop characteristics of the motor changes, the printer can improve the precision of the carried goods stop position.

Description

technical field [0001] The invention relates to a printer and a printing method. Background technique [0002] Some of the inkjet printers include a plurality of DC motors, and the driving of the DC motors is controlled to transport an object to be printed or a carriage including a print head. Here, further improvement in print quality has been sought in inkjet printers in recent years. In order to meet this requirement, the miniaturization of ink droplets is progressing, and in order to bounce such minute ink droplets to desired positions, it is necessary to improve the positioning accuracy of the stop position of the printing object. [0003] Here, Patent Document 1 discloses a method of improving the positioning accuracy of the stop position of such a printing object. In this patent document 1, the following technical content is disclosed: a speed measurement position is set at a position in front of a predetermined distance away from a target stop position, and when th...
