Around this design a 3mm bleeding/cutoff edge is needed
(leading to a total height of 24.6 cm and total width of 35.6cm).
The spine-fold is located 7mm from the spine on the front and back cover,
so the title etc. should be removed at least 1cm from the spine.

Below I will provide a description of my biggest results in my thesis and try to give some idea of the techniques used, … Read more
