Q. I have these great images and I want to use them in a brochure.
The printer says the files are low resolution but they look great on my computer screen.
Whats wrong. !!
You need a 300dpi [dpi = dots per inch] image to get good print quality.
These are known as HI RESOLUTION images.
Images used onscreen such as for web sites are 72 dpi .
The benefit of this is the speed with which such images load in browser windows.
Awareness of the difference can save you a degree of frustration.
