This rating is about the quality of the PDF, not the quality of the screen itself.
The text consists of vector graphics, which means it does not pixelate on zooming in,
and the image is of high quality.
Sadly it is only one of the images that were covering the back of the screen.
I see no reason why the other ones are not in the PDF.
Since this is intended for printing, I guess you could put your own choice of images on the back,
but it is still a shame.
