Method of multi-tone printing

An upper demand is printing (100) is connected with the apparatus relative motion of the channel (104) array of the film substrate (111) printing unit of the multi-stage printing method of deposition ink drops; the length of the nozzle of the position and size of each channel is provided with the upper longitudinal and frequency, the electric device (110,112,114,116,118) is provided with the pulse energy to the concave groove and connected with and frequency same or closed frequency of channel. From the channel of each concave to the film is corresponding printing unit of the deposition there are equal substantially in the pulse of ink drops. Pulse number of exerts is composed of a printing contrast of be. Ink drops blast type ink drops spraying and odd number serial number's of the flat serial number number's channel and a frequency on surface is the opposition.
