What about package maker ?? Great tool for folding carton packaging ...
is there any tutorial or book for pasharp?
I haven't tried anything for flexible.
Packmage is a commercial software and your link is a trial software.
I ever used Esko, so I was looking quadraxis web and it looks so nice, and sure is more cheap.
This soft looks quite well http://quadraxis.com/wp_multi_eu/?p=32 I think is like Esko Studio for Labels.
