Engraving, printing, and reading and inspection of 2D codes.
Concept of inspection for engraving, printing, and 2D code reading.
The reasons why engravings, prints, and 2D codes may not be readable are often due to insufficient contrast between the characters and the background or reflections from glossiness. Printed text is read based on the difference in brightness, while engravings are read through the shadows of the unevenness, which means the lighting needs to be adjusted accordingly. Engravings on metals or curved surfaces that do not show contrast may sometimes be readable in 3D by interpreting the unevenness. [Key Points] ■ Many unreadable cases are due to lack of contrast and reflections. ■ Printed text is read by brightness, while engravings are read by shadows of unevenness. ■ For engravings that do not show contrast, there is a method to read the unevenness in 3D. *For detailed explanations, please refer to the technical notes and downloadable materials in the related links.
