Offset printing uses 4-color inks, C (Cyan), M (Magenta), Y (Yellow), K (Key or Black), also known as CMYK. The ink is applied in layers to produce the final colors. Like a painter's palette, mixing the 4 inks can produce hundreds of thousands of colors. PMS or spot colors will be converted to the closest CMYK equivalent color during the proofing process.
If color is critical, we recommend that you order a hard copy proof to accompany your print job. calibrates our presses every day to ensure consistent color reproduction. Although we accept RGB files we recommend converting your graphics to CMYK to set color expectations to what a printing press can actually produce. RGB images are assigned AdobeRGB unless tagged with a custom profile. CMYK files are always assigned Gracol2013.
Rich black is a color combination that will produce a deep, dark, full black off press. Almost any color combination can be considered a rich black as long as there is 100% black ink and at least 1% of at least one other CMY colors. Our recommended rich black combination is 60% Cyan, 40% Magenta, 40% Yellow, 100% Black.


The most common reason artwork shifts on the proof is that the artwork is not set up or centered correctly on the original file. The proofing engine finds the center point of the artboard/canvas, and places it in the exact center of the trim size. We recommend using our layout templates or read our "Setting Up Your File" document for helpful information on setting up your file with or without the templates. Note: In the case of an EPS file, our system uses the bounding box for centering purposes. Saving an EPS file as a PDF usually corrects the shifting problem.

The lines on your PDF proof show where we will trim and fold your piece. The blue line is the final trim line. The red line is the bleed line. Any background image or color should extend to the red bleed line. The green line represents the caution zone area. Any text should stay inside the green caution zone line. The green/yellow dotted lines show where we will score and/or fold your piece.
There are two reasons a proof will not show fold lines. Either folding was not ordered or the job was ordered with a custom trim. If you are expecting your piece to fold and you do not have green/yellow dotted proof lines, please contact our customer service department at 877-405-3949, M-F (7am-8pm CT) for assistance.
