The invention belongs to the field of silk-screen printing, and particularly relates to a high-precision silk-screen printing technology with controllable printed material thickness. The high-precision silk-screen printing technology comprises the following steps that S1, printed materials are brushed on a printing stock by using a silk screen, the total volume of the printed materials and the sumof mesh holes are measured, and the average printed material volume of the printed material printed by single mesh holes is calculated; S2, the volume of required printed materials is calculated according to the area of required printed surface and the thickness of the required printed materials; S3, the number of required mesh holes is calculated according to the volume of required printed materials calculated in the S2 and the average printed material volume of the printed materials printed by the single mesh holes; S4, a silk screen with a same mesh number with the silk screen used in S1 is used, the number of mesh holes is controlled to be the number of the mesh holes calculated in the S3, and the distribution of the mesh holes is controlled to enable the shape of a mesh hole distribution diagram to be similar to the shape of a required printed material surface, and then a printed material is brushed; and S5, the printed material brushed by the S4 is pressurized and is enabled tobe expanded to the area required in the S2, and thus the printed material with the required area and the required thickness is obtained.
