This section covers information on how to assess and deal with your photo images prior to importing them into your book pages.

The importation procedure is covered in Step 05 BOOK LAYOUT


Saving your Photo Images

Save all your photo images in your IMAGES folder ready to import into your book pages. Before you import your images you must ensure they will be the correct resolution on your finished book page.

See below for information on resolution.


Clarity and Size

Resolution refers to the clarity or how clear the images are viewed, in relation to their finished or printed size. The naked eye can see at around 300 dpi (300 dots per inch) which is the standard resolution required. This way, images may appear sharp and concise when viewed by the average pair of eyes. If images are too small, or low in resolution, (under 300dpi), they risk looking grainy and pixellated once printed, even if they look fine on your computer screen. Except of course, to someone with major eye problems!

So the resolution is extremely important for the overall impact of your images. 

Your book page size will be what sets the parameters for your images. For example, you might have a background image which could go right to the very edge of your page. Alternatively, your image might feature on a page of text and fit well within the boundaries of the page edges. Whatever the case, when importing an image into your book pages it must be 100% of its original size when saved and at 300dpi.


Enlarging or Upscaling

Do not enlarge an image in any way to fit your book page. If you do, you will have just altered or lowered the resolution. You now risk sub-standard looking pixellated images on the finished printed article and there really are no winners. Start with the required size or larger.

Reducing or Downsizing

Images may initially be larger or a higher resolution than required and can be downsized to fit. The resolution will automatically be reduced when decreasing the size of an image.

By ensuring the correct resolution, your printed images will be of the highest quality when viewed on your book pages. If you understand how resolution relates to finished size (i.e. pixels to millimetres) then you will be able to calculate your requirements.

See below for the simple explanation:

  • Resolution equates to Image Dimensions (in pixels)
  • Convert the Image Dimensions (in pixels) to the Book Page Size (in Millimetres)
  • Finished Image Size in Millimetres determines resolution

  • The ratio of millimetres to pixels is 1 : 3.779
  • For every 1 millimetre of printed image = 3.779 pixels
  • This maintains a viewing resolution of 300dpi.

Take for instance a standard 6″ x 4″ or 15cm x 10cm. When printed it is around 150mm x 100mm. To calculate the actual resolution, multiply both measurements by the pixel ratio 3.779

The total sum is the image dimensions in pixels, or the resolution that would normally required for that size photo.

To work out if an image you have is the correct resolution to use for your book page, divide the image dimensions in pixels, or the resolution by 3.779. The result is the size of the image in millimetres when printed at 300dpi. Check this is the not too small for the finished size you require for your book page. If it is, you need to acquire a larger initial image or risk a grainy pixellated outcome.

For background images or wallpaper effect stye images that take up the whole book page, the resolution must also be correct and will obviously need to be higher than that of much smaller images featured on the book pages. To calculate, work from your complete book page size at the largest dimension when converting to ensure your images are big enough.
