How are books printed? It starts with… a file
Most people imagine the book printing process as a single machine that “swallows” the design and “spits out” the finished book. However, the reality is more complex. If you’ve ever wondered how books are printed, this article will guide you through all the key stages – from sending the file to the finished copy in your hands.
Printable file – more than just a PDF
The whole adventure starts with a file. The ideal file for printing a book should be prepared in PDF format, in a format compatible with the final size of the publication, with properly set bleeds (minimum 3 mm), margins, and in CMYK color space. We often receive files with errors, so before we start printing:
- we send a soft proof – a digital visualization of the book,
- we check the placement of graphic elements,
- we make sure that there is no risk of important content being cut off.
This is the last moment for corrections without additional costs.
How books are printed – choosing printing technology
Depending on the print run and quality expectations, we use different technologies:
- Digital printing: ideal for low print runs (e.g., 50, 100, or 300 copies). It offers great flexibility with short turnaround times.
- Offset printing: used for larger print runs, from 500 copies upwards. The unit cost decreases, and the color and detail quality is very high.
- Hybrid printing: combines the advantages of both technologies, e.g., offset cover and digital interior.
Some books require additional techniques, such as UV varnishing, gilding, or die cutting—we determine all of this on a case-by-case basis.
Paper, the background that makes a difference
When discussing how books are printed, it is impossible to overlook the choice of paper. Customers often ask: is it better to choose coated, offset, or eco-friendly paper? Here are some of the most common solutions:
- Book interior: usually 90–100 gsm offset paper, white or cream. Cream Munken is ideal for novels and prose books.
- Cover: 250–300 gsm matte coated paper, usually finished with foil (matte, glossy, or soft touch).
- Extras: ribbons, endpapers, headbands, gilding, embossing.
Interestingly, more and more customers are choosing recycled or FSC-certified paper – ecology is becoming one of the important criteria when choosing materials.
Bookbinding workshop – where magic happens
This is the stage where the printed sheets become a book. Depending on the type of binding, the process varies slightly, but most often:
- The middle section is folded and sewn or glued.
- The cover is separately laminated and creased.
- The whole thing is then stitched, glued, and trimmed.
For hardcover binding, an additional veneer is applied to the cardboard (2–2.5 mm thick), endpapers are installed and, if requested by the customer, ribbons or headbands are added. This stage requires precision, as it affects the durability and aesthetics of the book.
