Other LPI

LPI: (lines per inch) In the field of commercial printing, the resolution is expressed by how many lines per inch are equally spaced, that is, LPI (lines per inch). In the process of traditional commercial printing plate making, a screen should be added in front of the original image, which is composed of grid lines with equal transparent and opaque parts. These lines are also gratings for cutting anatomical images of light. Because light has the physical characteristics of diffraction, after the light passes through the screen, it forms dots with different sizes reflecting the changes of the original image, which is called halftone dots. A halftone dot cannot exceed the area of a grid at most. The more lines, the more layers representing the image, and the better the image quality. Therefore, LPI is used to represent resolution in commercial printing industry. Lpi: (Lightning Protection Association) American Lightning Protection Association.
