Abstract
A design assistance method for a liquid ejection device includes an acquiring step of acquiring a pulsation frequency fp of a liquid pressure applying unit, a compliance capacity C of a pressure absorber, and a composite inertance L of a liquid ejection head and a liquid supply flow channel; a determining step of determining whether a relationship between a cutoff frequency fc expressed by fc=1/(2π(LC)0.5) using the acquired C and L, and the pulsation frequency fp satisfies a predetermined relationship that satisfies fp≧fc; and an outputting step of outputting a determination result in the determining step.
