High Resolution Image for Printing

What is a high resolution image?

Common image files such as jpg, gif, png, tif, psd, bmp, are measured in pixels.

The resolution of a pixel-based graphic is the number of pixels within an inch: PPI (pixels per inch)

Whether the image has high enough resolution depends on the process being used. Generally, offset printers (paper printing) require a minimum of 300 ppi, screen printers (cloth printing) require 240 ppi.

In order to determine whether an image is high enough resolution, you need to know 3 things:
Your image's pixel dimensions (e.g 850 pixels wide)The printed size desired (e.g. want to print a 4 inch image on paper)The resolution required by the process your image will go through (e.g. printing 300 minimum ppi)
ASSUMING RESOLUTION NEEDED IS 300 PPI  If your image is: (pixels wide)
It can be printed in good quality at: (inches wide) 100
