Abstract

The invention relates to the technical field of printed matter, in particular to an analysis and detection method for green high-precision printing quality of books and magazines. The method comprisesthe following steps: using a standard book and magazine printed matter as a standard sample, and an analysis system collecting a defect-free printed matter as a standard image; taking the book and magazine printed matter to be detected as a sample, placing on an X-Y positioning workbench, through the regularity statistics of pixel gray scale and a digital original manuscript by an analysis system, respectively obtaining a pattern with a texture characteristic, a detection pattern obtained by printing and outputting, and a sample image made by combining frames; comparing and analyzing the sample image with the standard image; analyzing the characteristic quantity in a detection interest domain based on the digital image processing technology, and finally giving the relevant quality attribute description numerically. The analysis and detection method provided by the invention has high efficiency, time saving and labor saving, stable detection quality and great reduction in occurrence ofdetection missing.
