Artwork Specs / File Tips

  • Uploaded files must be under 100 MB. 
  • No bleeds are necessary
  • Set up your artwork proportionate to the exact banner size you are ordering
  • Keep text and important images at least 2" away from the edge to prevent the hems or grommets from going through them
  • Convert all text to outlines
  • Make sure no elements are selected for “Overprint”

Files that print best are:

  • .eps
  • .ai
  • .pdf

**Please note if your artwork contains complex gradients, textures, patterns or you are creating it in a software other than Adobe Illustrator, please flatten your artwork to avoid any printing issues**

We can also print 300 dpi or higher resolution files:

  • .tif
  • .jpg
  • .png

We print in four color CMYK or six color CMYKLcLm. Please keep this in mind when submitting files for printing as color tone shifting may happen if file is submitted in RGB format. If there is a specific PMS color you need, please specify that to us when submitting your order so we can help you verify that the proper color mix is used (vector artwork only).

Customer supplied files are printed as they are received so we cannot guarantee color, clarity or final output as we are just printing the supplied files and have not set them up for printing.

All of our printers are calibrated daily to International Color Consortium (ICC) coloring profile standards to ensure accurate color production.
