Processing Problems Scans Use only as much image data as is needed. For line art, scan at 600 to 1200 dpi at final size. Crop out unnecessary areas of the image. Two or three separate overlapping images may be smaller and easier to print if combined into a single image in Photoshop. If you don't need any part of an image, crop it out in the retouching program.
White borders take as much space as the image.
It is better to rotate images in your image manipulation program, then import. Page-layout programs make it easy to rotate images but require the printer to calculate the image data twice.
