I completley forgot to mention the most helpful book I have been using throughout this module.
'Designing sustainable packaging' by Scott Boylston.
I have scanned in the pages that I used regularly throughout designing.
I would recommend this book to anybody who is planning on designing a sustainable package.
Also, I am not 100% whether I have blogged about this but I can't seem to find the post when searching my blog for the label 'ink'.
