Page Building Standards

Note that these standards encompass aspects of design or composition that we feel are important to producing a quality printed product, but do not affect our ability to process the files or print the creative. New page files are spot checked for these criteria, but it is impractical to check all pages in all files. If we discover that submitted files fail to meet these criteria, we would alert the customer that quality may be compromised, but we can continue to use the files “as is” if the customer wishes.

Page Setup

PDF documents must be submitted in single page setup, as opposed to spreads. Page size and positioning must be consistent for all PDF files.

Contone Image Resolution

Contone images should be 300 dpi resolution with a minimum of 200 dpi at 100% placement size. Scaling images in a page layout program alters the resolution, so it is best to limit scaling in this manner.

Linework Resolution

Linework images should be 1200 dpi resolution with a minimum of 600 dpi at 100% placement size. Scaling images in a page layout program alters the resolution, so it is best to limit scaling in this manner.

Safety Margin

• The minimum distance from trim for any elements that do not bleed is 1/4”; 5/16” is recommended.

• Saddlewire bound jobs should have a minimum margin of 3/8”.

Gutter Margins

• Mechanical binding, such as spiral and comb-bind, require special consideration for placement of text so it does not get drilled through during the binding process.

• The requirement for text gutter margins is that they must be set to a minimum of 1⁄4 inches from punch holes.

• If 3-hole or 5-hole drilling is required or combined with workbook perforations, consult with your plant representative on the required margin.

• Side-sewn and side-stitched binding should have 1-inch type margins in the gutter.

Bleeds

Any page elements designed to print off the page, or bleed, must extend past the trim 1/8 “; 1/16 “ is the minimum allowed.

Printers Marks

Printer’s marks (registration marks, trim marks, page id’s, etc.) must be positioned 18 points or farther outside trim. Some software does not provide control over how far such marks are placed outside trim. In those cases leave printers marks off.

OPI

OPI or Open Prepress Interface, a technique of substituting high resolution images with proxies and then later inserting the high resolution images before final output, is not supported.

Backup

When a page design contains elements that are intended to backup, the compositor should carefully place those elements with exact precision to achieve backup accuracy.

Overprints

Japs-Olson honors overprint and knockout settings in files. In some cases, Japs-Olson fixes common problems such as whites set to overprint and small black text set to knockout of color. Other than these common problems, Japs-Olson does not attempt to alter overprint and knockout settings in files. In Acrobat use the overprint preview setting and print proofs with this setting engaged in the print output options to accurately represent how the page will print with respect to overprinting elements.

Blank Pages

Do not put anything on blank pages. Before sending files verify that blank pages are really blank. Include blank pages in the proper position for printing.

Trapping

• Japs-Olson prefers to trap your files. If supplied files already contain traps, ensure that you supply them as PDF/X-1a files, which will indicate the trap status. In any event, if you know the files are trapped, please inform us so that we don’t attempt to trap them again.

• If Photoshop images are supplied and the image should be trapped, it should be done so in Photoshop. We do not apply trap within rasterized images.

• Files created through copydot scanning of film cannot be trapped. The trap in the film will be carried to the files.

FPO

For Position Only copy and line work should be colorized using a spot color. This will allow Japs-Olson to correctly color separate the file for output. FPO body copy or address blocks must be colorized with its own spot color with a name that clearly defines its use. FPO line work such as Dielines, Perfs, and Scores must also be colorized with its own spot color with a name that clearly defines its use.
