6 x 9 book Premium and white pages
On the book building page, http://www.lulu.com/create/books I can't seem to choose Premium Paperback and Black & White on White for 6 x 9 inch book. We have done our book in 6 x 9 in word 2016 and have a lot of pictures (all black and white for a black and white interior). We would like like good quality for the pictures which I think needs Premium and I think white rather than cream would be better for the pictures. Am I understanding correctly? Any advise?
