Coarse dot full color was born
For a few years I worked with small newspaper seps and blew them up.
Low cost full color using a personal computer
All the experts in my trade said you couldn't do seps on a personal computer in the 80's. I kept trying and when I test printed a rack of pool balls for a local pool club I noticed that it was pretty good except for a couple of colors. For example the #2 ball was 100% cyan and 100% magenta which came out purple. Not everything is perfect, but I could work with it. I adjusted the colors to make the balls look right.
My Sample Shirt
It became a matter of managing expectations. I created a pallet of colors I could reach and printed them around a tiger. I could give a sample shirt and let a customer pick any of the colors around the tiger for their design. The great thing about this approach is that I could take a clip art collection of 500,000 images and use them with a few adjustments for trouble colors.
