If you place it at 50% (half size) the effective resolution doubles and the result is 144 PPI. If you place a 72 PPI image at 100% its effective resolution is 72 PPI. Effective Resolution: What is it and How do I Figure it out?Įffective resolution is simply the final resolution of any picture at the actual scale that it is placed within the document. Low Resolution 72 PPI Image Return to top of page. This file will also not look any better when printed. This picture will look very good when it is printed.īelow is an example of a low resolution 72 PPI image placed at 100%. Here is an example of a high quality 300 PPI file at 100%. In printing, we require a 300 PPI image at 100% to obtain good quality printing. For the sake of accuracy we will use the term PPI (or Pixels Per Inch). DPI (or dots per inch) refers to the resolution of output devices such as laser or ink jet printers and platesetters or film imagesetters. While this term is commonly accepted, it is not technically correct. This is referred to as PPI (or pixels per inch) but is also often called DPI. We will discuss pictures in terms of pixel density or the number of pixels per inch (measured horizontally). The pixels we talked about earlier can be thought of as those tiles. The larger the tiles, the less detail and thus the simpler the design must be. The smaller the tiles are, the greater the detail and the more intricate the design can be. A good way to think of resolution is to think of a digital photo as a design mosaic made up of those very small tiles we mentioned earlier. What is resolution? Simply put, resolution is the amount of information contained in an image. When preparing files for printing, the problem that most people encounter with their digital pictures is resolution. If you magnified a high resolution digital image to 1,600 percent you would see the pixels (or tiles) that the image is made up of. You may find it helpful to think of it as a very small tile, such as a floor tile. A pixel's appearance can be defined as a tiny square of color. The word PIXEL is a contraction of the term PIcture ELement. All images from digital cameras or scanners are made up of PIXELS. Resloution: Let's Play the Numbers Game.Image Resolution, Printed Size, and CMYK File Size s.When we are through you will understand effective resolution and will be able to figure scale and place pictures just like a pro. Just what does that really mean? Below we will explain just what resolution is, what it looks like when printed (high and low resolution) and how it is affected when pictures are placed within a document and scaled up or down.
#Web image resolution 72. or. 96 professional#
Pictures should always be supplied at an effective resolution of 300 pixels per inch (PPI) for best results when printing on professional printing presses. Image resolution is one subject that confuses a lot of people but it is not really so difficult to understand.
