CMYK pixel is colour mosaic artwork by printed images. Lines per inch is a term of printing to control the quality of printing. Depends on how many lines of dot printed in 1inch squeal area, a resolution of an image is different. I scanned images from the newspaper, usually, it is printed 80 lines per inch, to reavel it’s halftone structure. Images were megnified and sperated 4 CMYK channel and printed again.
