How can I make a stipple gradient in Illustrator CS4?
In drawings for design patents, the US Patent office requires, where shading is needed for clarity, stippled gradients. (Note: line gradients can be used unless the design incorporates lines that would be obscured/confused by the use of line gradients.) Generally, the lighting is assumed to be from the top left and the shading is implemented accordingly. Other gradient effects are forbidden.
Illustrator (version 8 -- yes, I've used it swimmingly for 10 years and only recently upgraded to CS4) has provided for stipple gradients. That is, you could make a 20% to 120% stipple for example. Now, with CS4, I can't see how to create a stippled gradient.
