Be sure to convert all fonts to outlines or curves before sending the file. Please set the size of the proof in proportion to the exact size of the custom banner's order. There's no need to include bleeds in the proof unless it is a part of the graphic. All text should be at least two inches from the edge of the banner's grommets. Acceptable formats include:

EPS (Encapsulated Post Script)
AI (Adobe Illustrator)
PDF (Adobe Reader PDF)
PSD (Adobe Photoshop)
JPEG (High Resolution JPEG)
TIFF (High Resolution TIFF)

Depending on the resolution and pixels, PSD, JPEG, TIFF files get blurry when enlarged. Thumbnail JPGs or GIFs cannot be used for large prints. If submitting these files, please follow these guidelines.

100% scale (full-size output) at 100 dpi, 50% scale at 200 dpi or higher, 25% scale at 300 dpi or higher, 10% scale at 600-1200 dpi

Vector: Line art is scalable to any size; it never loses resolution, and the image stays clean and crisp. Vector files can be submitted in any size, in proportion to your banner's size
