Today, outsourcing has become the norm, yet Diamond Envelope Corporation maintains a state-of-the-art PrePress Department using the latest available software on both Mac and PC platforms. We will accept your files on a variety of media platforms, as well as via email or FTP site. Our PrePress Department is environmentally conscious in all their work. This allows us to honor our service commitment to our clients.


Quality Control: file specifications are reviewed for proper sizing, and color configuration prior to any proofs being printed. We scan bar codes to ensure they meet standard regulations and that all information is correct, including the address.

Turnaround Time: scheduling for proofs is controlled directly by Diamond Envelope Corporation, allowing quick delivery times for time sensitive projects.

Postal Regulation Inspection: proofs are examined to ensure that they meet postal qualification specifications. Diamond Envelope Corporation is a certificated EMA Postal Partner.

Collaborative Partner: Our team works closely with you on each project, providing you with personalized service and support that allows you to focus valuable time on other parts of the project.

Submitting Artwork

​All large graphic files (over 8mb) should be sent to our FTP Site. Please contact your sales service representative for your specific folder prior to uploading artwork to the FTP site. If you do not have one, please contact us immediately so we can assign you a specific folder.

When submitting files:

  • Submit all art as Illustrator vector art (line art) when possible.

  • Include all image files and fonts required for your document.

  • Properly separate colors before sending the files.

  • Include registration marks with all of the files (to ensure proper positioning).

  • Include high-resolution files when using “.tiff” images (at least 300dpi preferred).
