Step 1) Make a package of your artworks, either hi res press ready PDFs or native packaged files including all the used fonts and links or images. 
When collecting files for output, use “Collect for Output” in Quark, “Package” in InDesign. These features assist in gathering all placed images and fonts needed for processing. Also the report file supplies helpful information about the files.

Step 2) Create a zip file from your packaged artwork by following these steps, you can use this to compress files, folders, or both:
1) Locate the items to zip in the Mac Finder (file system)
2) Right-click on a file, folder, or files you want to zip
3) Select “Compress Items”
4) Find the newly created .zip archive in the same directory
Note: Compressing artworks on windows operating system is similar to Mac and all you need to do is Right-click on the files or folders, point to Send to, and then click on Compressed (zipped) folder. 

Step 3) Go to File Transfer - FTP page and either upload your file(s) to our server OR request for an access code to our secure dedicated FTP server if your artwork file size is bigger than 500MB.
