ADOBE PHOTOSHOP ELEMENTS 4.0 159 User Guide Printer resolution is different from, but related to image resolution. To print a high quality photo on an inkjet printer, an image resolution of about 220 ppi should provide good results. Using a lower resolution you can print a slightly larger photo-if you are willing to accept some image degradation. You'll see a warning if you chose a print size that causes the photo to print at less than 220 ppi. About monitor resolution Your monitor's resolution is described in pixel dimensions. For example, if your monitor resolution is set to 1024 x 768 and your photo's pixel dimensions are the same size, at 100% the photo will fill the screen. How large an image appears on-screen depends on a combination of factors-the pixel dimensions of the image, the monitor size, and the monitor resolution setting. In Photoshop Elements, you can change the image magnification on-screen, so you can easily work with images of any pixel dimensions. 20" 15" 832 x 624 / 640 x 480 1024 x 768 / 640 x 480 A 620- by 400-pixel image displayed on monitors of various sizes and resolutions.

To display the image size of an open file O In the Editor, click the file information box at the bottom of the document, and hold down the mouse button. The box displays the width and height of the image (both in pixels and in the unit of measurement currently selected for the rulers), the number of channels, and the image resolution. To view the print size on-screen O Do one of the following in the Editor: • Choose View > Print Size. • Select the Hand tool or Zoom tool, and click Print Size in the options bar. The magnification of the image is adjusted to display its approximate printed size, as specified in the Document Size section of the Image Size dialog box. Keep in mind that the size and resolution of your monitor affect the on-screen print size. To change the print dimensions and resolution of an image You can change the physical printed size and resolution of an image without resampling. You might need to do this if you are sending the image to a print shop that requires files be at a specific resolution. If you are printing directly from Photoshop Elements, you don't have to perform this procedure. Instead, you can choose a size in the Print dialog box and Photoshop Elements applies the appropriate image resolution.
