In order to make technical problem solved by the invention, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, the printing down method of a kind of half tone that the embodiment of the present invention provides, comprises the following steps:
S101, tests the exposure energy that described half tone needs
By the exposure energy A adopting exposure energy test pieces to test out described half tone needs;
S102, carries out first time step of exposure to described half tone
After being sticked by the film on described half tone, first time exposure is carried out to described half tone, wherein, described half tone is carried out to the exposure energy B1=A*3/5 of first time exposure;
S103, carries out second time step of exposure to described half tone
After completing in S102 first time step of exposure carried out to described half tone, by the translation on printer glass planar of described half tone, by described half tone on described printer glass planar after translation, second time step of exposure is carried out to described half tone, wherein, described half tone is carried out to the exposure energy B2=A*3/5 of second time exposure;
