In Illustrator: How do you create the color Grey with just using Black, but without changing opacity? (it can also be used for other colors) Whenever we have to print something (shopping bags, wrapping paper, etc) we have to create a template for each color that is used. There is a "cheat" where you take a graphic element and fill it with tiny dots in stead of a 100% solid fill, thus creating the illusion that a second "lighter" color is used. The "further" the dots are from each other, the "lighter" the color will be. But since its the same base color, it saves on having to create another template.
I hope that made sense.
