File Preparation Guide

General File Preparation Guidelines

We accept print-ready PDF files only and here’s why. If you produce a print-ready PDF file with the fonts embedded, what you see on your screen will be very close to what you’ll see on the printed page. We’ve found that going to a PDF only workflow has reduced the chances of file errors in the print production process.

No. We only accept print-ready PDF files. We do this because print-ready PDFs have proven the most reliable way to reduce print production errors.

When you submit your pages, make sure they are in sequential order (1,2,3…). Our software will separate and number your pages just as they are submitted. Once we pre-flight and check your files, a print production proof will be sent to you for approval. Check this proof carefully to ensure that the pages are in the correct order. The proof will be what is printed and it’s your responsibility to make sure that everything is in the right place and looks good.

Designing Your Magazine, Catalog or Booklet

This is a term that describes artwork that goes to the edge of the page and “bleeds off.” To make this happen, the artwork that is printed is larger than the final size of the book. The extra artwork or image area is cut off in the finishing of the catalog, magazine or booklet. Usually, bleeds are setup in your layout and design tool. Standard bleeds are 1/8 of an inch (0.125).

The Trim Zone is the actual area of the book that will be cut out for the final size. This works in connection the Bleed of the product and the Safe Zone and is between the two. Usually, the Trim Zone is 1/8 of an inch (0.125) from the Bleed and 1/4 of an inch (0.25) from the Text Safe Zone.

The Text Safe Zone is the area defined inside the Trim Zone. This is the area where you should avoid having any content or text that you don’t want trimmed off in the finishing of your catalog, magazine or booklet. Usually this is set to 1/4 of an inch (0.25) from the Trim Zone.

No. We will add marks to your file before it is sent to print production.

RGB color space is for monitors and the internet only. CMYK colorspace is used exclusively in print production. If you design in the RGB colorspace we will have to convert your files to CMYK. This conversion will cause color shifts. Best practice, make sure all your images are designed using the CMYK colorspace.


Resolution, as known as Dots per Square Inch (DPI) is a measurement of how much information is included in a photograph or graphic image. To achieve the best print quality, you should make sure that all your graphic images have a resolution of 300 dpi. Images with a DPI of less than 150 will print with pixelization. Low resolution errors and warning will be identified on your print production proof. Please pay close attention to these warnings as they may affect the quality of the final product. 

Your final print-ready PDF should be sent in single pages, in the order that you would like them to be printed, in a multi-page PDF. Don’t send us pages in printer spreads, we’ll arrange your pages for the press before they are sent to print production.
