Pre-Press FAQ’s

Can you scan my artwork?

Yes. We have several state-of-the-art methods of scanning on site.

What dpi should I scan my artwork?

Images should be scanned at 300 to 400 dpi. Illustrations containing distinct shapes, lines or lettering should be scanned at a minimum of 600 dpi or ideally 1200 dpi. A higher resolution is required to preserve the crispness of the edges of an illustration.

What types of files do I need to provide?

There are two preferred formats: 1) Adobe PDF files. 2) Adobe InDesign or QuarkXPress files along with the corresponding image and font files. Other formats may be feasible; Please contact our EPP Manager for more information.

What does RGB mean?

RGB stands for Red, Green, Blue the three primary colors of light. Scanners and digital cameras create images in RGB format. Computer monitors and TVs use combinations of red, green and blue light to create what is seen on the screen. To be compatible with print production. The image files must at some point be converted to the proper format, typically CMYK.

Why do my proofs look so different from what I see on my computer screen?

Computer monitors display colors in the RGB color space as opposed to viewing a proof or printed piece which would use the CMYK color space. Each of these color spaces have different properties which affect how colors are displayed and perceived. Monitor output will also vary among different manufacturers. Also greatly affecting color is the lighting conditions present when viewing your screen, proof or printed piece. Systems are being developed to control lighting conditions and monitor calibration in order to closely match monitor output with final output. While this technology is improving, this has not yet become accessible on a broad scale. Normally it should be assumed that a monitor is not color accurate.

How do I determine what my spine width should be?

Many variables are used to determine the proper spine width for books, including page count, page thickness, and binding style. Please contact your Customer Service Representative for the proper spine width for your project.
