case bound book construction

The image above is a diagram of a case-bound book. These are the basic elements of a case bound book:

Chipboard:  we use a 98 pt thick chipboard. It is one of the sturdiest quality of the chipboard

Cover:  Cover is printed full cover and always laminated.  We currently can laminate gloss or matte finish on the cover

Endsheets:  A book has a 4-page white endsheet both in the front of the book block and back of the book block.  One of the pages of the endsheet gets glued to the chipboard and the other stays loose.  Therefore, all case bound books to get one white page each in the front and back of the book block
