![]() The total number of pixels printed in every square inch of paper would then be, in this case anyway, 72 x 72 (72 pixels for the width times 72 pixels for the height), which gives us 5184 pixels! In other words, for every square inch of paper, 72 pixels from our image will be printed from left to right and 72 pixels will be printed from top to bottom. The value in the Resolution box is for both width and height, not the total number of pixels that will print. Currently, our resolution value is set to 72 pixels/inch, which means that out of the 1200 pixels that make up our photo from left to right (the width), 72 of them will print inside each inch of paper, and out of the 800 pixels that make up the image from top to bottom (the height), 72 of them will print inside each inch of paper. The Document Size section of the Image Size dialog box tells us two things - what the current resolution of our image is, and how large or small the image will appear if we print it based on that resolution. The Document Size sections tells us how large or small the photo will print based on a specific resolution. It has nothing to do with how your image appears on your computer screen, which is why images you download off the internet usually appear much larger and higher quality on your screen than they do when you print them.ĭownload this tutorial as a print-ready PDF! Image resolution has everything to do with printing your image. The number of pixels that will be printed per inch is known as the resolution of the image, or "image resolution". ![]() Likewise, the fewer pixels you print per inch, the larger the image will appear on paper. Obviously, since your photo has a fixed number of pixels, the more of them you squeeze inside each inch of paper, the smaller the image will appear on the paper. The term "image resolution" means how many of your image's pixels will fit inside each inch of paper when printed. ![]() I cover it in much more detail in the Image Resolution, Pixel Dimensions and Document Size tutorial, but let's do a short recap. Let's find out why.įirst of all, let's get off the topic of downloading images from the internet, since we really shouldn't be doing that anyway without permission from the copyright owner, and look at image resolution in general. There simply are not enough pixels in most internet images to allow them to print at high quality, at least not without printing them at the size of a postage stamp, that is. So what can you do to make photos you download off the internet appear just as high quality when printed as photos you took yourself with your digital camera? The answer - absolutely nothing. The problem was simply that most photos on the internet have very small pixel dimensions, usually in the neighborhood of 640 pixels wide by 480 pixels high, or even smaller, and that's because images don't need to be very large in order to appear at a decent size and good quality on your computer screen, and also because smaller images download much faster on websites than larger images do (which is a whole other topic that we don't need to get into here). Image resolution didn't purposely set out to make your life miserable when you printed your internet photo. ![]() Have you ever downloaded an image from the internet and then printed it, only to get results that were, well, less than you expected? The image looked great on your computer screen, but when you printed it, it either printed at the size of a postage stamp or it printed at a decent size but looked blurry or "blocky"? The culprit is image resolution.Īctually, that's not really fair to say. In this Photoshop tutorial, we're going to look at how image resolution affects print quality.
