Analysis of the problem of folding and binding of digital printing

In the digital printing industry, late folding and binding occupy a significant proportion.

As a fast print shop, bookbinding is indispensable.

Digital printed sheets may crack at the image printed after creasing or folding

This is due to the drying of the paper, and the higher the quantification of the paper, the more likely this is.

Therefore, to avoid cracks, the paper should be kept at proper humidity and not too dry.

. In addition, fold the paper in the direction of the paper web to avoid creases.

Broken phenomenon.

If you are processing books and digital printing, the direction of the paper should be consistent with

The spine direction of the final finished book is parallel. Of course, on the printed paper

Lamination can also prevent cracks in the printed hinges. Indentation should also pay attention to the depth of the indentation

The degree should be moderate, if you use the creasing machine, you should pay attention to speed not open too fast.

At present, domestic digital print shops use more or booked, especially with wireless glue

The way of sticking, gummed book is not only beautiful, but also bound firmly. In design

When arranging the book, the printer is informed that the actual printed paper is digitally printed.

This change is especially important for digital prints.

Most computer design programs do not consider slight changes in paper thickness after printing

In the digital printing, the color material printed on the surface of the paper may cause the thickness of the printed sheet.

Change, cumulative thickness variation when binding dozens of pages of digital printed sheets

It may not make sense to make computer-calculated binding sizes. Therefore, we must master

Inter-professional proofs of production paper after digital printing can be used in print design

Accurately calculate the thickness of the book to ensure that the post-press processing achieves the proper binding size.

Like the offset printing of offset printing, the wireless glue binding of digital prints is also

Consider the amount of stapled cutting. In addition to leaving a 1/8 inch back allowance on the back of the book

In the other three sides of the book, a 1/8 inch cutting amount is also required.

In addition, a 1/4-inch glue area should be left in the lower part of the book cover to prevent

The glue penetrated into the next book in the binding. Wireless adhesive processing also requires printing

The blood cover should be larger than the body size. Wireless adhesive binding hardcover processing is also digital

An important post-press processing method in the fast-print binding mode.

The key to the hardcover process is how to bond the book block to the hard cover and produce it

Books that can be stored for a long time. Although the cost and cost of wireless glue binding

Time seems to be somewhat out of proportion to the digital printing for the short-run printing market, but

Some printing and binding companies prefabricate different colors commonly used in digital printing.

Hardcover bookcases of the same style and different sizes are used by digital printers, so wireless

Adhesive binding hardcover has also become a common binding method for digital printing.
