Each manufacturing facility has unique specifications and requirements so it is imperative to adhere to all of our file specifications. Do not assume what is required at other facilities will necessarily work for all of our production needs. During customer file creation should proper file specifications get overlooked or missed, that can result in errors in the finished product.

By the time your project is submitted for printing, you need to have thoroughly proofed the files. Please make sure you pre-flight and proof all files for accuracy before sending them to press. Our pre-press systems are automated and your files are not personally reviewed or proofed by any of our technicians or representatives. Interprint does not assume liability for errors on printing proofs that show in that completed project, regardless of the origin (see the two related topics on resolution and built black type below). Interprint is not responsible for the proofing of your files or proofreading of the proofs. All projects at Interprint are produced with proofs for customer approval, before the production process can occur.
Please Return All Proofs – We Need Them To Make Your Order. All hard copy proofs need to be returned to Interprint before we can proceed with the printing and binding of your project. This includes both the Epson color proof and folded/stitched Gerber proof. It is imperative that all proofs sent to you are signed by the buyer, then are returned back to Interprint so our production can begin.
* Proofs are used by our machine operators during the production of your order.
* Proofs are like blue prints or building plans. Without them we can’t build your project.
(2) Recommended Files – For printing only send files in CMYK format
Interprint recommends PDF files (CMYK). The accuracy of the processed data (your supplied files) depends on the features that are used in the creation of the document (i.e. transparency, color management, overprinting, etc).
Even using popular software to create a PDF file will not guarantee the file will process exactly the way it appears on the monitor.
Unfortunately, there are different issues that can arise depending on the platform (MAC or PC), the software used, the version of the software and even the features within the software used / selected to create the document during your file creation.
WYSIWYG , which is an acronym for “what you see is what you get” , the content (text and graphics) displayed onscreen during editing and file creation appears in a form “closely” corresponding to its appearance when printed or displayed as a finished product. The key here is that WYSIWYG is not absolute, and there can be a difference from the appearance on screen (your monitor) and the end printed product. Some software settings you may select will then display differently (on your monitor) compared to the “processed” file, which is necessary and part of the prepress / printing process.
(3) File Size – Send Files The Correct And True Size, Plus Bleeds
Should you receive the warning displayed in the illustration shown here, it means that your document is not matching the project specifications we understood your project was planned for. When documents do not match the pre-set specification for our program software, your page will be cropped incorrectly, and items on that page can be cut off and printed incorrectly. When viewing proofs online the “whole incorrect sized document is displayed”, therefore it can be hard to determine how the actual trim area will be on the actual printed piece.
The recommended and safest way to see and understand page position and cropping is always to review hard copy proofs which are produced on every project, please request to review hard copy proofs if desired. Your submitted PDF document size files need to match the trim size of your project, and the additional bleed provided should be .125” on all four sides.
(4) Your Computer Monitor / Display
Your computer monitor displays color in the RGB color model. RGB monitors can display more colors than can be matched in print. Conversely, some CMYK colors cannot be matched on-screen. Moreover, RGB gamuts vary widely between devices with some gamuts being considerably wider than others. WYSIWYG (what you see is what you get) doesn’t always apply. The color you worked so hard to get “just right” on your monitor doesn’t look the same when you print it. By their very natures, monitors and printing presses reproduce color in completely different ways. A monitor uses the RGB color model. A printing press, by contrast, uses the CMYK color model. Moreover, RGB and CMYK have different color gamuts, or ranges of reproducible colors. It’s always best and recommended to review the hard copy physical proofs to ensure you are satisfied with color and content before the project is produced.
(5) When Reviewing Your Proofs
If you do not mark changes or errors on your proofs that need to be made, errors will show in the finished printed product. There is no substitution to checking your proofs carefully to ensure accuracy. Please note that Interprint DOES NOT review proofs as our prepress systems are automated and not physically reviewed by any Interprint Employee.
(6) USPS Mail Regulations
Interprint DOES NOT provide advice or approval to customer’s proofs, designs or physical attributes of the printed piece in regards to USPS regulations and compliance issues. It is recommended that you work directly with the USPS in all matters concerning standards, regulations and acceptance of the printed piece and ability to mail in accordance with the USPS. Your artwork / files are used “as is” therefore it is very important that all the correct information is included and set up correctly for the mailing process. Please note that Interprint DOES NOT review proofs as our prepress systems are automated and not physically reviewed by any Interprint Employee.
For assistance with mailpiece design questions and review of your mailpieces, contact a Mailpiece Design Analyst by contacting the MDA Support Center:
(7) Submit High Resolution Files
When reviewing proofs, please keep in mind that images viewed on your monitor where you designed your project, and the hard copy color proofs, are either presented or made from different equipment, and media, compared to the traditional offset printing process / press that your order will be printed with. It is important to ONLY submit high resolution files. It is your responsibility to submit files in the correct High Resolution format.
(8) Do Not Build Black Type Or Art
Do not build black type, or other elements intended to just print in black, in CMYK / 4-color process. This will cause undesirable printing results such as color variation and poor registration in the end printed product. When reviewing proofs, black type built in CMYK can be hard to visually detect during the proofing process. It is your responsibility to submit files in the correct printing file format.
(9) Making Changes At The Proofing Stage
If a change is made on a page of a magazine, catalog or brochure, please note that the entire page may be re-ripped. Therefore, it is imperative that you re-check all information of the entire new proofs. Do not just look at your changes, review everything on the new proof for accuracy. It is VERY important review all proofs carefully before the project is printed.
(10) Natives Files Can Be Problematic
Customer Supplied Media – Customers who supply native files run a greater risk of problems with the way their files process. Issues with fonts, placed images, transparency, and overprinting are more common with this traditional postscript workflow. The popular file format to supply is PDF.
(11) File Formats We Process
PDF Setting: High resolution PDF/X-4 setting. (CMYK)
Color Profile: SWOP2006_Coated3v2. Regardless of what profile is attached, we strip out all profiles attached to the file, then add back SWOP2006_Coated3v2 at the processing stage.
(12) Print Documents
Saddlestitch Products (Self Cover or Plus Cover) All pages in one document as single pages, not spreads (including the cover)
Perfect Bound Products:
* Text (inside pages): All pages in one document as single pages, not spreads.
* Cover: Create a separate document for the 4 page cover, as a spread, including the spine (check with your Interprint representative for correct spine width)
This will avoid using a type style you do not have an actual screen and printer font for.

(15) Perfect Binding And Saddlestitch Layout Specifications
Perfect Binding and Saddlestitch Binding require different page / file set up. Please review our file specifications before files are designed or set up. Use the below illustration as a guideline to set up your documents for either Perfect Binding or Sadddlestitch products. If you have any questions regarding preparing your files, please contact us before your start your documents.
* Gutter Area – Safe Margin Zone – See below illustrations for gutter area / safe margin zone.
* Saddlestitch Gutter – Requires safe margin zone of 1/4 inch to 1/2 inch depending on how many total pages your project has.
* Perfect Binding Gutter – Requires safe margin zone of 1/2 inch to 5/8 inch depending on how many total pages your project has, and due to the glued spine and hinge involved in our perfect binding process.
