Artwork Specs

Files that print best are .eps or ai (in version CS5 or lower) converted to outline. We can also print high resolution .pdf, .tif, and .jpg formats. Typically 300 dpi or higher is suitable for signs.

We print in four color C, M, Y, K or six color C, M, Y, K, LC, LM. Please keep this in mind when submitting files for printing as color tone shifting may happen if file is submitted in R, G, B 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 ICC coloring profile standards to ensure accurate color production.
