What are the applications of printing quality inspection

The visual survey and the three-dimensional lack of surveying and the lack of printing can be divided into two-dimensional defects and three-dimensional defects from their spatial characteristics. The two-dimensional defects can be often referred to as poor overprint, color shift, missing printing, missing printing, pasting, missing hot Conventional printing defects such as hot stamping and scalding; three-dimensional defect refers to the lack of physical space differences between the label plane and the label plane, such as bubbles, scratches, glue overflow, creases, embossing defects.

The primary goal of the printing quality survey system based on visual skills is to ensure that the above two types of defects can be surveyed without defects. The ancient printing quality survey mainly relied on manual termination, and the primary goal of the quality survey system based on visual skills was to replace the human eye.

Three-dimensional printing defects such as bubbles, scratches, glue overflow, creases, embossing, etc., are often difficult to be reliably surveyed by humans, and can only be inspected when the human eye and the lack of orientation are at the required angle under the required optical requirements Out.

When this type of deficiency is manually surveyed, it is required that the object being surveyed is circling at a random angle so that the human eye can survey it. The angle of visual imaging is the same. If plagiarism is manually maneuvering the surveyed object, it will undoubtedly increase the complexity of the entire survey system.

The door is used to survey the optical system of the lack of 3D printing. The effectiveness of the 3D survey and its functions are connected to the features of the missing pictures after collecting the good pictures of the missing 3D printing. Beijing Lingyun Company is working on the related image processing algorithm for this kind of defects. Research and develop special survey software for the lack of such surveys. The survey results are as follows:

Surveying this type of lacking survey software and its survey effectiveness Surveying this type of lacking survey software and its survey effectiveness The three-dimensional lack of survey developed by Lingyun has four characteristics:

Super lack of survey talent: can survey shallow scratches with a depth of 0.02mm and small size bubbles of 0.1mm2; all-round lack of survey: have the same survey talent for three-dimensional defects in all directions; complete width survey with an innovative optical system: maximum surveyable The width can reach 1000mm; exclusive algorithm software: adopt exclusive software to complete high-precision survey.
