These guidelines are designed to help you create electronic art that will be as trouble-free as possible, reducing the extra costs and chance for error associated with art improperly prepared. Resolution lower than the recommended range will result in a visible loss of detail. Resolution higher than the recommended range is unnecessary and will only increase file size. Impressions currently scans line work at 900 ppi. Resolution needs to be higher for line art than in halftones to avoid a coarse, jagged appearance.
Impressions can batch convert color screen captures to grayscale for printing.
T S Any of these types of art can be saved in a variety of formats, depending on the program and platform used to create the files. Encapsulated PostScript Format, also known as EPSF, or EPS, is also acceptable. Formats like JPEG, BMP, PICT, GIF, PNG, and others can often be translated to a format usable for printing. Native program formats, with the exception of Photoshop, are to be avoided. Impressions would be happy to provide more information about the usability of specific file formats.
