Why I found there are regular “Bands” on some 3D lenticular images which are printed by color printers?
The regular “Bands” on some 3D lenticular images are very likely caused by software weaving. For most other lenticular software, they don’t support “Printer” interweaving mode. As we well know, almost color printers, especially the color inkjet printers, their printout DPI values are integers like 300, 600, …, or 360, 720, …etc. But, normally we can hardly get the “Output DPI” (= lens LPI x View Number) as a “common factor” or a “common multiple” value of the output DPI value of most color printers. As a result, when these lenticular images are printed, the color printer will then use its dithering algorithm to resize image’s DPI so as to meet the same printout size. If so, different printers might have different dithering algorithms. And, that will very probably cause regular “Bands” on some 3D lenticular images.
