is this working for anyone using cs3? it is not working on my end..

How to control the number of dots - I tried reducing the dpi, the phisical dimensions and the resolution - every time the result is the same. Is there a way of altering the script's parameters to control that? I am also trying to get rid of the small interpolated dots the script produces. Do you know some way of doing that?

Thank you in advance.
