What Is A Lay Flat Book?

A lay flat book simply put is a type of book binding technique that lays completely flat when opened on a surface. When you open a lay flat book, there is no gap or gutter (the gutter of a book is the blank space where the left and right pages meet) between the pages. This means that you can create a book with seamless, high impact double-page spreads. 
Lay flat binding is an ideal solution for creating a lay flat photo book, luxury coffee table book or showcasing landscape shots that are panoramic and require seamless uninterrupted printing. Lay flat is one of the most effective book binding types when it comes to visual storytelling.

 

Our lay flat books come with two cover options;

Soft cover book:

A soft cover book offers seamless flat pages complete with a soft yet sophisticated cover. Perfectly flexible when reading and exploring a book’s captivating content.

Hard cover book:

A hard cover book exudes luxury with its 2500mic hardback cover, a suitable fit for books that need to stand the test of time whilst featuring the same lay flat qualities as a soft cover book.

 

How Are Lay Flat Books Printed?

The lay flay book printing method is rather simple but takes time and dedication to perfect to achieve our signature high quality product. Our team of book binding specialists have years of experience under their belt and they ensure that every book that leaves our factory is of only the highest quality.

 

Step 1: Pre-Press

At instantprint, we understand that books are complex, requiring true attention to detail. Before sending to print, our skilled studio team will get to know your artwork, checking the specifications in detail and preparing your file for print using our rigorous and free 10 point artwork check.

 

Step 2: Printing

Machine: Landa S10P

Your design will be sent down to our factory where our skilled operators will begin printing your design onto your chosen paper stock. Here, your inner pages will be printed as well as your cover.

In our factory, you’ll find the best of the best when it comes to our equipment. Printed on our state-of-the-art machines, your book’s artwork is brought to life.

 

Step 3: Embellishment and Lamination

Machine: MGI JETvarnish / Autobond Laminators

At this stage, if you have opted for any embellishment or lamination on your book’s cover, this will also be added. Utilising our MGI JETvarnish, this machine can add Spot UV and foil to your book’s cover. For lamination, the heated chrome rollers of our Autobond Laminators create a strong seal, combined with a rubber counter-pressure roller to smooth the laminate out. 

 

Step 4: Folding

Machine: Heidelberg Stahl BH56 Folder

When your design has been printed, the folding process begins on our Stahl BH56 folding machine.

When printing a lay flat book, the interior pages are counted in multiples of four to ensure that your book isn’t left with any blank pages when bound together, which is why, on our website, you’ll find that the number of printed pages you can choose from go up in multiples of 4.

With lay flat binding, your paper is usually printed on 16 pages but 8 page, 4 page and 2 page signatures are also used depending on your book's total page count.

It’s important to note that we only print our lay flat books on certain stocks due to the intricate drying process of the pages after gluing.

Signatures and inner pages don’t take into consideration your book cover as this is printed separately. 

 

Step 5: Gathering

Machine: Kolbus KM 600 Perfect Binder

Once the pages have been folded they are then gathered in the correct order, ready to be duplexed together. The pages are collated on the Kolbus KM 600.

 

Step 6: Duplexing

Machine: Kissun DB440 K-Binding Machine

The process of creating a lay flat book involves duplexing or glueing one folded sheet to the next, back to back to create the pages and overall book block. This is unlike perfect binding where the individual pages are glued into the binding in the spine.

The last page of each signature is covered on one side with adhesive and glued to the first page of the next signature. This process is continued until all the signatures are joined. This means that the overall thickness of your book’s pages will become double. Two 140gsm pages glued together will become 280gsm thick. For our lay flat books, we use an Expert White stock from Fedrigoni to ensure durability and quality.
Our lay flat manufacturing process utilises the Kisun DB440, a dual feeding system that applies adhesive to the paper sheets, the special adhesive we use for our lay flat books is Alfast 654.

 

Step 7: Pressure

Once all of the pages have been duplexed and glued together, this creates what is known as a book block. A book block is all the collated pages of a book created before being bound or covered.
After all pages have been securely bonded, our operatives will position the book block into the compressor. Placed under pressure to help the glue bind with the pages, this helps to create a strong bind that can be opened and laid flat with ease once dry.

 

Step 8: Hard Cover Trimming

Machine: Horizon Variable Trimmer HT 1000V

At this stage, if you have opted for a hard cover book, once the adhesive is dry, the book block is then trimmed along three sides to ensure the final pages are neat and consistent before binding. Our Horizon Variable Trimmer HT 1000V trims off any excess paper where necessary.

 

Step 9: Soft and Hard Cover

Machine: Kolbus Case Maker and Kolbus BF513 Casing In Machine

With the finished book block glued and trimmed, the cover can be added. This may be a soft cover or a hard cover.

Soft Cover:
For our soft cover lay flat books, a wrap-around cover is added to the outside of the book block using wet glue to create the finished product.

  1. The cover is expertly creased.
  2. Then the book block is cased into the creased cover.


Hard Cover:
For our hard cover lay flat books, a few more steps are involved. If you opt for a hard cover, your book will be attached to a 2500-micron greyboard where we will cover your book's front and back pages as well as the spine. 

  1. The greyboard, the material that makes the cover hard, is guillotined to size. The greyboard hard cover will be slightly larger than your specified inner size such as A4, usually 3mm to ensure the cover is attached correctly. 
  2. The paper cover and greyboard inners are then brought together using our Kolbus case maker. 
  3. The book block is then cased into the hard cover.
     

Additional Finishing

Our expert team are also able to offer a range of additional finishing options to our lay flat books, including;

  • Ribbons
  • Head and tail bands
  • Throwouts
  • Cover embellishments 

 

Step 10: Soft Cover Trimming

Machine: Horizon Variable Trimmer HT 1000V

For soft cover books, once the adhesive is dry, the final book is then trimmed along three sides to ensure the final pages are neat and consistent. Our Horizon Variable Trimmer HT 1000V trims off any excess paper where necessary.

 

Step 11: Final Checks

Once complete, our expert team will take time to check over your finished product to make sure it meets our high standards. Your books will then be sent to our dispatch team who will carefully package your print ready to be collected by our couriers and shipped to your business.
