Submitting Files via E-Mail:

Many e-mail systems limit the size file which can be attached and files are sometimes “corrupted” by e-mail systems. You can increase the chance of your file’s success by “stuffing” or “zipping” them before you attach them in your e-mail or upload to an FTP site.
You can submit your files to dtp@keystonepress.com as an e-mail attachment if the attachment is under 20 Mb in size. Or, send your file to our FTP site. FTP is used strictly for transferring files. There is no file-size limitation, but E-mail messages must be sent separately.

Submitting Files via FTP (File Transfer Protocol):

Connect to: ftp.keystonepress.com and enter the Username: printfiles and the Password: 473W.

In the window that opens, you should see a folder called Keystone Press. Drag your file or folder to the Keystone Press folder. It should begin copying. Depending upon the size of the file, it may take a few seconds or several minutes to finish copying. Additionally, let your customer service representative know when you drop files on our FTP site. Whether you use e-mail or FTP, always include a PDF version of the file for reference. If your PDF file is intended for final output, please include “hi-res” as part of the file name.
NOTE: In some versions of Internet Explorer you'll have to click on "Page" and then "Open FTP Site in Windows Explorer" to bring up the ftp site.

Mac OSX finder supports Read-Only access to FTP sites. To upload files to our FTP site from Mac OSX, use a third-party utility such as Fetch® (fetchsoftworks.com).
