It is basically just a different method of halftoning and the square dot do interlock as I do with halftones. Index style printing is good for low color count images if the image has a lot of colors Simulated Process might be the better way to go. Index on images with a lot of colors can require more color and be more difficult to get an accurate color palette for the Paletted 8 bit image conversion.

@@advancedtshirts thank you sir. Have to say, you make it look so simple. But go into detail on why you do it the way you do. Even if I have to watch the videos 30 times. An image of such quality is my goal and with a video like this I'm sure I can do it over time. Right now I get excited over a simple two color design. But you gotta crawl before you can walk.
