Questions about printing a illustrated book
Im creating a childrens illustrated book with my brother.
It is a square book, 8.5x8.5.
The illustrations he has created digitally are currently 132 dpi. Is this ok? Or must it be 300dpi? If he needs to change this what is the most pain free and least time consuming way of doing so?
Also, do the colours have to be cymk colours or if rgb is okay?
Is there anything else we need to think about in regards to printing colour illustrations, printing a childrens picture book etc?
Any advice, help appreciated!
