This question most definitely deserves to be asked directly to my printer but since they're currently on leave for the week, figured I'd give it a shot here to get a general idea on how I should approach my design.
I'm getting a text printed and want to add a debossed detail in the existing printed word spaces. It's a small run of 500 cards at the most. Quick and dirty example:
So it's a limited space and could easily look off center. On average, what kind of precision range should I expect? 0.5 point? 2 points? 1/16 inch? More?
