Exceeding the suggested PPI could result in a file too large to output or additional megabyte charges. Save time and expense by testing the procedures that you will follow from start to finish.

Media Size	Printable Area	Device Available DPI	Suggested PPI at final dimensional size	Device Color Mode
8.5 x 11	8 x 10.5	2400	200-300	CMYK
11 x 17	10.5 x 16.5	2400	200-300	CMYK
12 x 18	11.5 x 17.5	2400	200-300	CMYK

Considerations for scans, file size, and resolution
When preparing your scans, remember that a higher scan resolution does not always result in better print quality. Excessive scan sizes result in huge files that extend print times with little improvement in print quality.

Vector-based graphics are suitable for type and logos, even when they are scaled to larger sizes. Raster images, however, must have the proper resolution for the final dimensional print size. Because the number of pixels in a raster image is fixed, increasing the size of the image decreases its resolution, and decreasing its size increases its resolution.


Terms to understand
Pixels per inch (ppi) - Pixels are the individual elements that make up a digital file.

Dots per inch (dpi) - A measure of output resolution rendered by printers.

Perceptual Maximum Resolution - The resolution beyond which you visually experience no appreciable gain in the printed output.
