High Resolution Image for Printingadmin
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)
