Take care in preparing your files to ensure quick turnaround and to avoid setup fees. Our price and turnaround estimates assume your files are prepared correctly. To ensure proper
setup, supply a 1-up layout (we'll do any needed imposition). Example of a 1-up layout:
Always provide a laser printout as a "go-by". You should also include a "folding dummy" as a reference/bindery guide, if applicable. Saddlestitch Booklet Guidelines Saddle stitch books must be printed in "Printer Spreads" rather than "Reader Spreads". To avoid setup fees, submit your file in Printer Spreads on a 12x18 layout page. (Actual image size must not exceed 11x17 with an additional 1/16 inch bleed.) InDesign or Quark files submitted as Reader Spreads will incur a setup fee, usually $25 - $50. If you prefer to submit Reader Spreads, set up as "Facing Pages" with the document size the finished book size. Design your book in "Reader's Spreads", with any bleeds at a minimum of .0625". PDF files set up as single pages or "Reader's Spreads" will need to be placed into a page layout application by our prepress department. Additional charges may apply. Make sure your PDF includes bleed. Illustrator or Freehand Files are generally not recommended for book layouts. Extensive prepress or layout/design work is usually required. Additional charges and turnaround time will apply. Setup Guidelines View the guidelines below for design specifics.
Platforms supported: Macintosh and Windows (see supported software at right). Fonts: Include all screen and printer fonts used in your file (don't forget fonts used in placed graphics). Image Size: 11" x 17" maximum, plus 1/16" bleed (see file setup tips above). Placed Graphics*: Save images in TIFF or EPS format (don't use DCS format or save with screen angles or transfer functions applied). Scanned images should be 300 dpi at 100% scale. Linework resolution on the HP Indigo is 812 dpi; 1270 dpi for the Quickmaster. Color: Work entirely in CMYK mode. Never use RGB! Trapping: Unlike conventional presses, digital presses have extremely tight registration due to the fact that the plates are imaged directly on press. In most cases, trapping is not necessary. However, if you feel trapping is required for your job, use a 0.3 trap. Crop Marks: Use a 0.25 pt black line for crop marks if needed. (You won't need to include crop marks on a 1-up layout.) Bleeds: Bleeds should be set for 1/16 inch on each side. Anything you want to print
to the edge of the paper must be set up to bleed. *Considerations
for scans, file size, and resolution Vector-based graphics are suitable for type and logos, even when they are scaled to larger sizes. However, when you increase the size, any included raster images must have a proper resolution for the final dimensional print size. Because the number of pixels in an image is fixed, increasing the size of a raster image decreases its resolution, and decreasing its size increases its resolution.
