Casebound catalogues require a treatment of inner pages that is very similar to that of other types of binding. We need to apply the necessary bleeds to all elements reaching the page boundaries and above all, a safety margin of at least 15 mm should be left on the catalogue's side next to the spine, since this type of binding makes the reading in this area a little more difficult, and leaving a larger margin the problem disappears.
When it comes to hardcover binding, it is important to note that both design and production should be high-quality and made professionally. If they aren't, you can make your catalogue anyway, but keep in mind that since you spend money on a luxury binding, production and design should at least get to the same level.
An important aspect of the inner pages is that in hardcover binding there is a new concept, a new element, as we explained before, and that is the endpapers. Endpapers may also get designed, of course, but we have to take a number of precautions:
- Endpapers are usually printed on uncoated offset paper. As you know covers are usually printed on coated papers, so if covers and endpapers share colous, being different papers the tones will also be different. This issue should not be a problem at the design level. There won't be big differences, but colour won't be exactly the same as the paper stock is different.
- Endpapers must have the same size as the inner page block. And keep in mind that the distance between the design elements and the cutting lines must be large, that is, please do not place anything close to the trimming line. You should keep 10 mm at least. The reason why this is better is because when making the hardcover, in order to properly adjust covers and endpapers, sometimes it is necessary to trim the endpapers a bit, so the design elements must be kept well away from the cutting lines.
- Another important point to keep in mind is that there are 2 endpapers, that is, we have to think 2 designs, because we have one endpaper pasted down between the inner front cover and the first page of the inner pages block, and another one that is pasted down between the inner back cover and the last page of the inner pages block.
- And last but not least, we have to bear in mind that endpapers are like a 4-page sheet (a bi-fold) with 1 page pasted down to the front or back cover, and therefore has no design whatsoever. When designing endpapers we must remember that we just need to design 3 pages for each endpaper sheet.
Dealing with covers
Dealing with covers here is a little different compared to other products, as we have to take into account a number of parameters which we highlight below:
- First, we must bear in mind that hardcover binding requires the cover to have a minimum bleed of 2 cm applied to all sides. This is necessary because the cardboard that confers rigidity to the cover is partially wrapped by it, therefore, if we didn't apply bleed, this wrapping could not be made.
- Another important point to bear in mind is that the cover is going to be laminated, because it does not make sense having a luxurious product such is a hardcover catalogue and not having a luxury cover, with a shiny, glossy finish.
- When designing the covers, we must take into account the following proportions, because hardcovers have their own peculiarities:
Hardcover catalogue 21 x 29.7 cm (DIN A4 closed size).
measurements in cm.
WIDTH x HEIGHT:
(2 + 21 + 0,3 + 0,5 + spine + 0,5 + 0,3 + 21 + 2) x (0,3 + 29,7 + 0,3).
2 = bleed.
21 = book width
0,3 = extra book width (important).
Casebound book covers are always 3 mm wider than the inner pages block.
0,5 = margin required for the binding (also important).
We hope that these general indications will help you to properly prepare your hardcover. These indications are orientative, since they depend on the bookbinder machines, but we have to say that they are quite approximate. Concepts are what really matters. When you are going to publish a hardcover catalogue, ask your printer about the measurements that your covers should have to guarantee the best work.
