What type of Files are Best for Carbonless Forms (or NCR) Printing?

Generally a Vector PDF file is the best. WORD and Excel files are usually fine also. Vector files will produce the best image quality. If possible, all fonts should be converted to outlines. Bitmap files may print fuzzy or with faded ink coverage. If bitmap files are the only thing you have, they should be at least 600 DPI and grayscale. All blacks should be 100% grayscale black for best results. We need 3/8" margins all the way around.
