Prepress book layout design process two

Fiber direction of paper

The fiber direction of the paper must be parallel to the spine of the book. This is the most basic rule and it must not be ignored. Sometimes there are some advertising prints that use the opposite fiber direction, but this type of situation is very small and requires careful planning. In general, the fiber direction must be parallel to the gutter.

The weight of the paper line

The controlling factor in determining the number of pages a book page should contain is the weight of the paper. The heavier paper should be folded into an 8-page stack. The lighter paper is usually folded into a 16-page stack of pages. The best is 32 pages, but there are also 64 pages. A specific decision is governed by the details of the print.

The right angle of paper

The need for precise origami prints and "flip-over" typesetting requires that the paper be squared before printing. In other cases, the right edge of the edge of the paper is at right angles to the edge of the paper jaw.

Shingling of Papeer
When using the saddle stitch binding method, the number of pages inserted on the inside surface may be many, but for thick paper, it is easy to produce a phenomenon of "Creep" "Pushout". For such prints, in order to resist the problem of “extrusion”, it is necessary to see how much adjustment is necessary to deal with the amount of change in the binding edge and the outside, and select the size of the book page accordingly. Some examples, for folding and cutting purposes, must adjust the "Cuutter" so that it is properly aligned with the page number.

Embedded plan

In printing, printing more colors is a one-time printing fee. Therefore, in the design of some prints, it is necessary to pay attention to the distribution of colors on each page. For example, a 16-page book page requires color and the other part needs only a single ink. However, if all the pages are printed in color, it will cause waste. If there are different procedures for printing the burial plate and the binding method, different color page allocations will result.

When designing a print, the paper must not be used. There must be eight three-inch to one-half-inch mouthpieces, and some bleeding prints must be left with more space. Otherwise, the ink at the bleeding position will accumulate in the tape circle. Contamination caused by the cylinder or pressure cylinder.

Some large areas of the field and some young lines or juvenile nets on the same surface, will cause the control of the amount of ink is difficult, the large field of imprint needs a lot of ink, so the young thread becomes thicker, on the contrary the right amount of ink will not make young Fine prints are thicker, but the actual location is not solid enough.

Before burying, you should first use a white paper, folded into a post by the folding method of the origami machine, and then write the page number on the paper in order to unfold the paper so that you can know the arrangement position of the book page.

In some cases, when colors are widely separated on paper, a two-color effect may be achieved in one printing process. This is called "Split Fountain Printing." The principle is to place two colors of ink on both sides of the ink tank.

Folding of paper

The so-called "folding" (Folding) refers to the printed paper, turn it into a book section (book section) or page number arranged by the fold (Signature). It can also be applied to the production of advertising prints, such as folded booklets, leaflets, and mail advertisements.

"Folding" is mainly divided into "Parallel fold" and "Right-angle fold". Different forms mainly change from these two types. "Parallel fold" means that each fold line is folded in a parallel direction; and "vertical fold" means that after each fold of paper, at least one fold line is at right angles to the folded fold line.

Most of the vertical discounts are for book printing, which is called "book folding." Parallel folding is generally used for advertising mails and brochures, but it is also used for very narrow books or repeated printing jobs. For example, on a six-page origami, divide a piece of paper into three pieces, and fold the left and right pieces inwards. Call them "Three-leaf panel folds," such as left-up folds and right-hand folds. Downward folding, called Accordion folds or Z folds; and over six pages of accordion style folding, known as Over-and-over-folds, is also a common The folding method.

Binding

The definition of the binding is to connect the printed books and periodicals in order, making them sturdy, beautiful, easy to read, and preserved. The installation of nails also includes the processing of other printed products, such as hot stamping, filleting, beer dark lines, envelopes, paper bags, punching, and nail holes.

Book binding book English is called (binding), can be divided into "hardcover" and "plain" two. For product listings, advertising brochures, annual reports, etc., the designer must design according to its purpose, content, page number, paper quality, weight, size, and thickness. First of all, it is also necessary to have a certain understanding of the binding method, and then in the design of the arrangement can be more effective.

paperback

It is nailed in the form of nails or stitches, and soft-covered nailing methods are also used on the outside, such as phone books, novels, and magazines.

hardcover

First, the inner pages are cut and attached, and then they are combined with the pre-made hard leather. So, the cover is slightly larger than the inner page. Books such as books and encyclopedias.

Hardcover, and then according to its back and cover dressing method, can be divided into the following three categories.

Soft back: The back of the book is soft. With the opening and closing of the book, the back can be bent, so it is very easy to turn over. However, the characters on the back have the disadvantage of being easily damaged.

Hard Back: The back of the book is hard, and the text on the back of the book is not easily damaged. However, reading the book is not as good as the soft back. Keeping blank space near the gutter is the place to pay attention to when designing.

The so-called “backside” is between the number of pages in this article and the pages of the book. When the book is opened, it will leave a hole so that the text on the back of the book will not be damaged, and the binding process can be smoothly performed when the page is turned. Encyclopedias and other books that look at a little bit of everything are taken in a back-to-back fashion.
