I want to create a block of colours like this (from top left c:0 m:0 y: k:0 to bottom right c:100 m:0 y:0 k:0) There are 100 colours there and I am currently doing a line of 10 with a fade with 10 steps and then duplicated that down. I then added a white line grid to make colour difference more apparent.
Is there a way to fade from top left to bottom right and get a blocky effect without having to do it a line at a time? Do note that each square above has no gradient in itself.
I need to make about 100 pages and want a quicker way to do this. I can use either photoshop (preferable) or illustrator.
