The resolution always depends on your application. When you want to process "normal" engraving jobs, use "500dpi resolution" and "Air Assist On". This will combine very good quality with a fast working speed. You can adjust both parameters in JobControl® via the material database.
For photo engravings on paper, we recommend reducing the resolution to 250-333 dpi, as the screen points appear slightly enlarged on paper and would overlap if a higher resolution was used.
If you only want to cut the paper, set the resolution to 1000dpi.
