Creating The Image

The secret for getting the best results out of your imagesetter, according to Dennis Ryan, product marketing manager for Heidelberg's prepress equipment, lies in asymmetrical resolutions.

"Lowering resolution in the slow scan direction so you can expose faster, but doubling the resolution in the fast scan direction gives you the same or more levels of gray, while at the same time running less dpi in the slow across drum direction," hints Ryan.
