How To Optimize Images

  1. 1. How to Check Image Size and Resolution A Formatting Tutorial
  2. 2. Proper Size and Resolution <ul><li>When submitting an image for publication, it needs to have a suitable size and resolution . </li></ul><ul><li>Using Adobe Photoshop, it is easy to check the size and resolution of an image. </li></ul><ul><li>Although this tutorial will use Photoshop, there are many programs you can use to check your images. </li></ul><ul><ul><li>Most of them will give you the option to check the size and resolution of the image in the Menu bar. </li></ul></ul>
  3. 3. Image Size and Resolution Requirements <ul><li>If you are submitting images for the book’s cover or interior, they need to have a resolution of no less than 300 PPI, or Pixels Per Inch. </li></ul><ul><li>These images should be submitted in the size you want them to be printed. </li></ul><ul><ul><li>If you want your image to be a full bleed, or to extend to the edge of the page, we recommend that you add 1/8 inch of bleed space to the top, bottom, and right side. </li></ul></ul><ul><li>For interior images, we recommend at lease 6 inches tall for portrait-oriented images and 6 inches wide for landscape-oriented images. </li></ul><ul><ul><li>If you are publishing a color book and want the images to be in full bleed, add ¼ inch of bleed space to the top, bottom and outside edge to get your final minimum image size. Keep in mind that the outside ¼ inch will be cut off in the printer. Unfortunately, you cannot do a full bleed in a black and white book. </li></ul></ul>
  4. 4. Check Image Size and Resolution <ul><li>In Adobe Photoshop, you can check an image’s size by going to ‘Image’ and clicking Image Size . A dialogue box will appear that will show you the image size and resolution </li></ul><ul><li>You can change the image size and resolution in this box. </li></ul>
  5. 5. Changing Image Resolution <ul><li>Be careful when changing the resolution of an image. You will see that sometimes, it negatively effects the size of the image. </li></ul><ul><ul><li>As you increase the resolution of an image, the image will get smaller. </li></ul></ul><ul><li>To save images from becoming smaller, make sure Resample Image is selected in the Image Size dialogue box. Choose the Bicubic Setting in the drop down menu. This setting is best for image enlargement. </li></ul><ul><ul><li>This process can sometimes make an image look blurry. Sometimes the trade-off is acceptable. </li></ul></ul><ul><li>If the image is too small, or the resolution is too low, it is best to rescan the image at the appropriate size and resolution. </li></ul><ul><ul><li>Scanning is usually available at your local office supply store. AuthorHouse also offers scanning for an additionally fee. It is one of the many self-publishing services we offer. </li></ul></ul>
