Justified text in print is achieved through the work of people who are trained in typography. Tools such as kerning and tracking require human involvement. Because of digital technology it is now much easier for type designers to build contingencies into a font while it is being designed but even that technology is only focused on the more common type problems.
It is interesting that you used the graphic which you did because this particular example illustrates problems with full justified text. Notice the spacing in the second line. That is one problem. Another problem is what is sometimes called "rivers." In the first line, notice the space between dolor and sit, then let your eye drift down to the space between mea and at, then down again to the space immediately below that in the third line then to the space after the period in the fourth line and continue down the text, this is what is called a "river" and it is a distraction which professional typographers seek to avoid as much as possible.
Although well done full justified text is pleasing to the eye, poorly done full justified text is more distraacting than left justified text.
