The Printing of my Book

I had the opportunity this week to see my book being printed, so of course, I grabbed that chance with both hands and with my son, Jeremy, we went to the plant of one of the UK’s few large format book printers, Butler Tanner & Dennis.

Located in Frome in Somerset, Butler, Tanner& Dennis have a 166 year printing history and their reception contains a very old printing press used by the firm.

The plant is very large indeed and contains all manner of machines needed for book printing and manufacturing. BT&D proudly claim they are one of just a few companies that do everything under one roof in the production of books. For someone like me that has no experience of or any prior knowledge of printing and making books, the plant is a marvel of machines and looking at most sets up a guessing game of trying to work out what they do. Some of the machines are brand new and a marvel of modern technology, but at the same time, these are used alongside many that are decades old and still work perfectly well today.

The plant is laid out broadly in the order that a book is produced, with incoming materials such as paper at one end and the completed book exit at the other. The paper store is large but paper having come from specialist plants in many countries. Unlike newspaper production, all of the incoming paper is cut into flat sheets, not rolled.

My book was printed on the newest and biggest printing machine in the plant, a Heidelberg, which is capable of printing 15,000 sheets an hour at peak. Yes, you did read that right, 15,000 large format sheets an hour!

At about 12 inches by 12 inches (30cm) mine is a large book, and each of the sheets going through the printer contains 20 pages of my book on each side. The printing of the book pages is therefore done at a phenomenal speed.

This is the machine that makes the plates. They are very thin and made from aluminium. Each sheet going through the printer needs 4 plates (cyan, magenta, yellow and black)....

This is one of the plates ready for printing.....

The huge Heidelberg printer. With its six printing positions. Just four were being used for my book. The paper gets fed into the far right hand end, passes through the six printing positions and the left hand end is where the printed sheet is dried. The completed sheets are delivered in a neat stack at the left hand end.

The top of the yellow printer. It is hard to see from these pictures just how fast everything happens. This drum is spinning at an incredible speed....

The guys opened the side panel of the drying area, so we could see the sheets going through that part....

A not very good picture of the completed sheets being stacked. It is really just a blur....

The printed sheets measure 63 x 47 inches / 1.6m x 1.2m and each contain 20 pages of my book. Due to the way the sheets are folded into sections of the book, half of the pages are printed upside-down.

Each machine in the plant has a “minder”. This is Julian Keel (AKA Biff) who was looking after the Heidelberg printer. He can adjust many aspects of the print as the machine is working. We watched him run off a couple of stacks of different sheets while we were there and I would say he has a very challenging job....

As each stack of printed sheets is finished, they are moved by a fork lift truck to a waiting area. These are not my stacks, but a book just ahead of mine in the production process....

When the whole book is printed, the large sheets are folded into 2o page book sections by some amazing folding machines. Prior to actually folding the sheet, each is perforated to make the folding flatter. Depending on the size of the individual book pages, these machines need to be set up for each book....

Once each 20 page section of the book has been folded and prepared, these are loaded into a long machine that first stitches the sections and then collates those sections. Each section has a printed mark so the machine can automatically check that the collating has been done properly and all sections are in the correct order....

The collated sections then begin to take the form of a book. These are known as book “blanks” and are stacked ready to be moved to the next part of the production process. Note how the pages are just rough cut at this stage....

On a separate production line, the hardback covers are manufactured. This is still done in the same plant, by a different team. Known in the trade as “cases” these are not for my book, but another just ahead of mine....

Next is a very clever, multi-function machine that brings together the cases with the book blanks, trims the pages to the correct size and glues the book into the base to make the completed book. All that is left after this is to add the dust cover, or “jacket” as the printers call it....

A similar process happens with the softback books, but a totally different machine is used to bring the various parts of the book together....

Quality control is important at every stage of the process, with people having to sign off every part of that process. If they didn’t check each stage until the book was completed, a minor problem in one process would mean rejection of the whole print run. This is where the completed books are checked....

Overall, the visit to the plant was fascinating. Having never before understood how a book is produced it was terrific to see each part of the process. The guy managing the production of my book, Clinton Walker, went out of his way to show us around and explain the process to us. Along with the Key Account director, Jeremy Snell, we were made to feel very welcome and it was clear the team at Butler Tanner & Dennis are excellent at what they do. I am really looking forward to seeing the end result.

When the book is finalised, they need to be shipped to the various supply locations and then we will be ready to go, in time for the book launch on 4th march.
