Illustrator Resolution

I'm doing a printwork in Illustrator for the press. What settings should I choose? How sharp? Thanks!

Flatness = Printing Device resolution / Output resolution

Loosly translated this means.

Flatness "equals" your printers optimal resolution "divided by" The output resolution you have set.

Now... when dealing with Flatness (a term associated with paths) a smaller number is better.

SO..

if your printer is a 1200 dpi printer and you set the output resolution at 300 dpi.... you are printing with a "Flatness" of 4....

1200 / 300 = 4

I generally shoot for a 2 or at the very least a 3

remember the lower the flatness the longer it takes to print.

Also if you are taking this to a "commercial" printer to have it printed. You should consult them about their specifications.
