Bookbinding and types of paper
Internal printing choices and the type of paper
For the book interior file, there are different types of paper based on the various printing types (color or black and white) as well as the basis weight.
For black and white books, the following types of paper are available:
- white paper (woodfree): 80 gsm
- cream paper: 70 gsm
- High-quality white paper: 135 gsm (if the book contains many graphics and/or black and white photos).*
*CAUTION: Texts in black should not be created in four-color process (CMYK), but only in 100% black. Black and white images should be created in grayscale.
For color books you can choose between:
- Matte coated paper 115 gr - ideal for books that contain mainly text, but also images, especially graphic elements and/or illustrations
- matt coated photo paper 135 gr - recommended for printing books containing mainly images and photographs
Note: Images, graphics, illustrations, and photographs should be created in four-color process (CMYK).
The 115 gsm paper is NOT recommended if you have pages with colored backgrounds and/or images with vivid ink.
The 135 gsm paper is NOT recommended if you have pages with very dark and/or black backgrounds.

Cover
The cover will be printed in color regardless of the printing type you choose for the inside. To print the cover we use 300 grams coated paper, and you can choose between a matte or glossy finish. Currently, is not possible to print on demand using hardcovers or flap covers, or to insert a book jacket.
Bookbinding
Print-on-demand books are created as professional quality paperbacks and bound with PUR glue and trim, to ensure a perfect seal.
The print
The POD distribution service is run through a print shop that uses digital printing. What is the difference between digital and offset?
In offset printing, the image is generated on a matrix plate, then transferred to a rubber support and through this imprinted on the sheet of paper. The result is of great precision, but only for medium/high runs without any customization. In digital printing, on the other hand, the image is digitally processed: this means that the print is continuously customizable (it is possible to change the image contained in the matrix at any time) and above all suitable for small runs, even starting from a single copy.
Given the premises, someone might want to opt for offset printing, but it should be remembered that it has the disadvantage of preparing the initial matrix (which implies a higher cost than digital) and it is not possible to make changes on the plate once prepared, without considering that it is suitable and sustainable only on large numbers of copies.
