So, an array of 50 pulses per inch in each direction then? (that would be 2500 / sq in)
The “simplest” way would be to create an array of lines, and set the lines to use dot mode (which will shudder a lot because it stops for each dot) or perforation mode, with a short cut value, like 0.1mm, and a longer skip value, to get yourself to 50 dots per inch. Using 0.1 / 0.4 would give you that.
