A high-precision offset printing method applies production standardized digital methods and means to create model development software so as to eliminate errors resulting from different used equipment and materials, is quite convenient and effective for operation of error correction and is an innovation and development of control theories of an offset printing technology. The technical architecture of the high-precision offset printing method includes a high-precision screening color separation technology, a high-density printing reproduction technology, a high-saturation printing reproduction technology, a long-contrast-level reproduction technology, a color management control technology and high-precision offset printing technical standards. Printed matters produced by applying the high-precision offset printing technology have the advantages of high precision, bright color, strong stereoscopic impression, good light impression and the like, technical indexes of the high-precision offset printing method conform to current international and national standard systems, index value exceeds standard expectations, quality bottlenecks of the traditional offset printing technology are broken through, and the offset technology portion makes up defects of existing printing theories and technologies.
