Example Embodiment

[0041] See image 3 , image 3 A system block diagram of the printer 30 to which the inkjet printing control system 36 of the present invention is applied. In one embodiment, the inkjet printing control system 36 of the present invention is applied to a printer 30, and the inkjet printing control system 36 is used to control an inkjet head 39. The printer 30 includes a motor driving device 32, a motor device 34, an inkjet printing control system 36, an inkjet head driving device 38, and an inkjet head 39. The motor device 34 includes a motor 37 and an encoder (not shown). The motor 37 is a DC motor. The motor driving device 32 outputs a second signal 302 to the motor device 34 according to a first signal 301. The motor 37 of the motor device 34 receives the second signal 302 to correspondingly drive the inkjet head 39 to move, and the encoder of the motor device 34 outputs a third signal 303 to the inkjet printing control system 36 according to the movement position of the inkjet ...

Abstract

The invention provides an ink-jet print control system to control a ink-jet head. Said invention comprises a motor controller, a delay-time generator connected to say motor controller; and a timer connected to say delay-time generator. Wherein, the motor controller is used to calculate the moving speed when ink-jet head reaches the ink-jet position; the delay-time generator can generate a delay time according to said moving speed; and the timer can calculate a ink-jet time after the ink-jet head reaches said ink-jet position and output a ink-jet signal to control said ink-jet head when the ink-jet time equals the delay time.

Description

technical field [0001] The invention relates to an inkjet printing control system (Printing Control System), which is used to control the time for an inkjet head (Printing Head) to eject ink droplets at different moving speeds. Background technique [0002] The inkjet head of the existing inkjet printing device is driven by a motor, so that the inkjet head moves back and forth. When printing, the inkjet head will experience the moving process of acceleration, constant speed and deceleration. There is a certain distance between the inkjet head and the printing paper. When the inkjet head ejects ink droplets at different moving speeds, the relative falling positions of the ink droplets falling on the paper are also different. If the moving speed of the inkjet head changes when the inkjet head continuously ejects ink droplets, it will result in uneven density of the printing result and affect the printing quality. In order to avoid the deviation of the relative drop position ...
