• Bitmap files should be 300 dpi (dots-per-inch)

• CMYK color mode

• Layers must be flattened

• Do not use Alpha Channels

• Vector data must be rasterized

• Do not save tiff files with LZW compression

• To reduce file size you can save EPS files with JPEG Maximum compression, this should be avoided if there are large blocks of color or text over white. JPEG compression removes data info and in these specific cases, artifacts may occur reducing print quality.
