Hmm ok think of it this way. most everything you look at when printed is in the 150 - 600 dpi range. Dpi ranges are used for a variety of print viewing distances. Say if you're 5 feet away you can't see the dots on a 150dpi print. When you look at a nice magazine and you're like wow look at these pictures they're so clear most likely you're looking at an image which was printed using a higher dpi setting. When you look at a newspaper you notice right away that the picture is composed of dots, or some kind of pattern. In print they're called dots on your monitor they're called pixels. Now paper is far more capable of carrying dots/pixels than your monitor is. Your monitor will do up to about 200 dots per square inch. This is why a lot of things look a little distorted or blurry on your computer display vs. paper. Now a basic rule of thumb for image resolution on your monitor to print is that the image should look about 3-6 times as big on your monitor veiwing it at 100% or 1:1, as it will when you print it. There are big differences between two types of files, Raster files and Vector files. Vectors are just what they say based on direction. So you can take a Vector and make it as big or small as you want. Vectors are used in stuff like fonts, and line art which you'd find in a comic. Rasters are images you'd take from your digital camera. Because there are so many features which change at resolution in a raster image you can only scale the picture down in size without loss in percieved quality. If you try to size the image up you're going to reduce the percieved quality of the image. Let me show you an example of a print sized picture. This is how big you'd need the image to be, in order to be of sufficient |
