High-quality printing requires 3 to 4 times bigger image resolution as it appears on the monitor. Thus, "good looking" images on the monitor may be unacceptable in printing. For high-quality images in our book, we need to know the size of them in pixels.

  • The image size can be found in the image properties in Windows Explorer, e.g. 1024x768, 2500x1600, etc..
  • In Google Image Search, that number is shown next to the picture if you put your mouse over it.
  • As a rule, approx. 10 cm wide, high-quality printing can be produced from a 1000 pixel image. Thus, a high-quality 20x16 cm print can be made from a 2500x1600 pixel image.
  • However, not even a passport photo can be taken from a 300x200 pixel image.

In Word, images “tend to jump” to another page if e.g. we try to change their size. This is an annoying problem for longer material and there is no good solution to it.

Word does not handle transparent images well (such as png). It is more fortunate to use JPG images.
