Please prepare a single file for each side of your project (See Document Set-Up).
PDF and JPEG files are automatically compressed.
Check List for All Applications:
All projects must be set up with 1/10" bleed on all four sides
(e.g. 3.5 x 2.0 trim should be 3.6 x 2.1).
Make sure all the colors in your file are CMYK @ 300 dpi.
Solid blacks should contain parts of all four colors to create rich black.
Be sure to save the final version of your file.
