Abstract
An ink-jet output control method used to control the printing quality of ink-jet output device achieving an even distribution of ink dots is provided, wherein the ink-jet output device, being driven by a step motor, is a printhead carriage on which a printhead is mounted. The ink-jet output control method includes: firstly, to set a number of time pulse values of every two adjacent ink dots in each step of the step motor under different velocity models; then, store these set values which are non-identical in a memory unit; next, the printhead determines the time interval of ink-jet signal sending according to these set time pulse values; lastly, the printhead spreads ink dots on a recording medium with unequal time interval interpolation on receiving ink-jet control signals, such that ink dots are well distributed, an even interpolation and better printing resolution can be achieved.
