Anyone who was around fifty years ago can probably remember the first attempts at laminating book covers. Exactly when this was is one of these things it’s difficult to establish with precision. I remember all the paperback covers in my early days in publishing as being without any kind of finish.
People of my generation will fondly remember the wonderful tendency of early cover lamination to de-laminate, allowing the bored reader to peel large strips of lamination off the cover. They’d come off along with a sort of neat shadow print of the cover as some of the ink came along with the peeled layer. This pastime had the same appeal as the later popping of bubble wrap.
In this picture you can see where the lamination has been stripped up the middle of the spine. Printed by Jarrold and Sons, Norwich in 1963.

And on Rosalind Mitchison’s history, below, you can see from the pitiful remainder of the lamination that all the red ink has come away when the lamination was peeled off. The little bit of lamination remaining with its red ink kind of suggests flames over Stirling Castle: a serendipitous reader contribution to cover design. The book is one of Methuen’s University Paperbacks reprinted in 1974 by Fletcher & Son Ltd. also of Norwich. (I don’t think lamination applied in Norwich was particularly prone to stripping!) Actually one can’t be sure Jarrolds and Fletchers did in fact print these two covers, though I think it’s highly probably they did. They certainly did print and bind the books, but back then, or very shortly later, we were to go through the beginnings of the separation of cover printing into a separate specialist business. Book historians beware: it’s impossible to know who printed a cover, except by examining the publisher’s archives.

The advent of lamination was doubtless a minor sort of event which nobody thought it worthwhile making a note about. I am finding it difficult to establish just when the event took place. I suspect it wasn’t till the sixties? I do have a Livre de Poche edition of La Princesse de Clèves which is laminated and claims to have been printed in 1961. Maybe it started earlier in different countries, though the Thames & Hudson one shown above dates from 1963. Britain has ever been a bit too wedded to tradition — and T & H as international co-edition specialists were especially open to overseas influences. That French cover was printed by letterpress, and you can see the lamination’s urge to become detached where the impression is deep.
The spine, as so often, is the weak point for delamination — all that folding and bending: it wouldn’t take too much to get La Princesse’s peeling going here. Which is also true of Hugh Williamson’s Book Manufacturing in its third edition from Yale University Press: this book reminds us that at one time we’d leave the jacket flaps unlaminated — not sure why; maybe to save the cost of the plastic roll. In the early days laminating covers was a bit like applying Saran Wrap/Cling Foil to a sheet of paper with a hand iron. Mr Williamson’s book shows the wrinkling which imperfect application would cause back then. (A nice Michael Harvey hand-lettered design.) The book was printed in 1983 at The Alden Press in Oxford: which is where Hugh Williamson was Managing Director, retiring that year. Maybe they did the jacket too, though they probably farmed it out locally.

There are two basic ways of putting a shiny (or matte) coating onto a jacket or cover: press varnish and film lamination. They can come in various finishes, gloss, matte and intermediate versions sometimes referred to as satin. Before we had lamination if you wanted to make a cover shiny your option was basically to print on a highly calendered shiny cover board. This can never get as shiny and impactful as lamination. The next best (and cheapest) option was to apply a press varnish. As its name implies this coating of varnish was applied by a specialized press. There’s a tendency for some of the varnish to be absorbed into the paper, and press varnish cannot provide the same pop as lamination. Lamination film comes in various types, with a stout polypropylene film as the topmost grade. For book covers lamination is applied using an adhesive, some pressure and some heat. It’d be hard to strip modern film lamination off a book cover: not sure which of the ingredients has improved since the early days: maybe all of them. Nowadays it has become possible and fashionable to combine press varnish and lamination: spot varnish enables you to highlight selected areas of the cover by printing on top of a film lamination.

Here’s a picture from Bridgeport National Bindery showing the same book with matte and gloss lamination. You pays your money and you makes your choice. Is it slightly amusing that we’ve had to invent a type of lamination which makes it look as if the book didn’t have any lamination? There is of course the protection element, and there is something really sensual about the feel of a matte lam cover.
We really spend the money to laminate a cover for marketing reasons: the impact of the cover is paramount, though it is true that the lamination also adds strength to the cover or jacket. Because the eye is basically seeing reflected light when it distinguishes colors, the brighter and more reflective a shiny surface is the more light it will reflect and so the more intense any color will appear.
Because ink, unprotected by lamination or varnish, will tend to smudge and rub off, before we developed cover coatings book covers tended to be fairly simple. The shinier, more coated, the paper, the easier it is to wipe off the ink. You would hesitate to print a halftone on a cover for fear of its smudging — if it was printed on a coated paper which holds the ink on the surface more than an uncoated paper (which is what you’d want to do with a halftone), the tendency to rub will be even greater. Typographical layouts and solid blocks of color were the norm. Nowadays we assume trade jackets and covers are going to feature elaborate artwork: they can do this thanks to lamination.
Graphic Arts Magazine had a piece in 2011 comparing both methods.
