Use phone camara to evaluate printing quality

Features & Capabilities

The basic concept for evaluating print quality using a mobile phone camera is as follows: The printed material must display a 3x3 grid of colors as shown in the image. The composition of these nine color blocks has been mentioned several times before: CMYK full coverage, CMYK 50%, and C50MY40 gray balance. The camera must distinguish the range of this grid, extract the RGB values, convert them to CIE system values, and then calculate values ​​such as color difference, TV, and gray difference. Finally, a score is given based on the full-page color difference, TV difference, and the brightness and gray difference of the gray balance.
