| Resolution Resolution refers to the number of individual pixels that make up an image per area. The higher the resolution, the sharper the image. There are images that are constructed using vectors rather than pixels. These images have an advantage as they will not become pixelated when enlarged(1,2). When printing, it is necessary to understand what resolution will do. If, for example, we have an image that is 30 pixels across(3), if it were to be printed at 30 pixels per inch, it would look sharp(4). If instead, it is printed at 10 pixels per inch, the image would not be as sharp(5). This is because the image is made up of a finite number of pixels (30 in this case) and we are trying to spread those over a larger area (Evening). It is important to understand this so that when you are ready to print any design layout or image you will have the correct resolution so that it is clear and not pixelated. The general rule is to have a resolution of 300 ppi (pixels per inch) at the size you would like to print. You could get away with 250 ppi if necessary. |
