Does anyone know how to do this?
I don't need any particular symbol, I would like to know how to do it so I could apply any simple symbol as a halftone. I saw an example on spin.co.uk. On the studio projects page under posters and it's page 4.
I would be keen to know if there are any plugins for illustrator or photoshop (mac) that do a similar thing but in a less time consuming manner. I know there is one on the PC called Halftone 2.0 that allows you to use custom symbols as the basis of your halftone pattern.
Allow me to point out an additional advantage of doing it in Illustrator though: One can easily change the form and size of the dots by editing the Symbol.
Unfortunately the grid itself cannot be edited that conveniently …
