Soft surface hardcover book binding production process

The soft surface hardcover book refers to the new hardcover process which is different from the general hardcover book processing in the cover making process. The book core processing and the nesting processing process are exactly the same as the general hardcover book.

Production process

Book core processing

Folding → Sticking ring lining, single page → matching book → lock line → flattening, bundling → brushing and drying → splitting and cutting → rounding ridges → three sticks (sticking cloth, gauze, book back paper or cheese) paper).

2. Cover processing

Cover (after UV finishing, embossing, etc.) → press line, die-cutting → brush adhesive → fold four sides, paste soft cover.

3. Nesting processing

Coated seam glue → book cover and soft bag cover sleeve → pressure groove → sweeping lining → flattening and setting.

Soft surface hardcover book cover pressure line size design

Square back

The size of the book back is based on the actual book back size measured after flattening and bundling. 32 open and 32 open books are 3.0mm, 16 open books are 3.5mm, and eight open and eight open books are 4.0mm.

Due to the overlap behind the book backpack and the occupation of the plug cloth, it is necessary to increase 2.0 mm to 2.5 mm on the left and right sides of the book. The four sides are set to 15mm. If the size is not large enough, the white side can be enlarged.

Square back soft surface hardcover book cover line size is:

High = finished product height + 2 × floating mouth width;

Width = measured book back size + 2 × finished product width + 2 × floating mouth width 10 2> < (2 or 2.5 mm) (book back overlap and plug cloth occupation).

2. Round back

The size of the book back is measured by the actual book back size measured after flattening and bundling, which is 1.1. The floating mouth of the book with 32 open and 32 open is 3.0mm, and the floating mouth of 16 open books is 3.5mm. The mouth is 4.0mm.

Since the back of the round backpack also has overlap and the cloth is occupied by the cloth, it should be added 2.5mm-3.0mm on the left and right sides of the book, and the four-fold side is set to 15mm. If the size is not large enough, the white side can be enlarged.

Round back soft surface hardcover book cover line size is

High = finished product height + 2 × floating mouth width;

Width = measured book back size × 1.17 10 2 × finished product width 10 2 × floating mouth width + 2 × (2.5 or 3 mm) (book back overlap and plug cloth occupation).

Regardless of the die-cut size of the square back or round-back book, it is necessary to add 2 fold widths in height and width on the basis of the cover press line size, and the mouth is 2×15mm-30mm. The angle of the four corners is 45°, so that the four corners are just right at right angles.

Post-press hardcover technology is becoming more and more personalized and diversified, and soft-faced hardcover is a new hardcover process. With its low cost and simplified process, it has been favored by more and more publishers and readers.

Quality control in printing process

The quality of the printed matter is affected by a variety of factors, the evaluation standard of product quality, can be a destination for Seihan, printing and finished products, according to the corresponding technical indicators, effective measurement and control.

Measurement of film The color of film includes transmission density and dot area.

Film accuracy or not, will directly affect the quality of the subsequent processes. The transmission density includes the gray haze of the film and the field density. Ash Mist is the density of the film, mainly monitor the light transmittance of the films. The density value of the substrate should not be higher than 0.05D.

Gray dew through high, you need to increase the exposure of the print, resulting in network changes too large and small dot loss.

Quality control in printing process Field density is also the highest density film, mainly monitoring exposure and the development of the chemical program is correct or stable, the general high-density value should be between 3.8D to 4.0D (laser film will be high-some).

The density of the field is too high, the image is reduced, on the contrary, it is low density, and the blank part of the print is not easy to be exposed, resulting in undesirable phenomena. Measuring dot area has two functions:-is the linear imagesetter, the second is to see the output of the dot area is correct. The linearization imagesetter can avoid the instability of output quality due to the change of the developing and fixing conditions.

If the film dot area is not correct, it will affect the print and printing quality.

The measurement of a printing plate At present, the use of the dot type has amplitude modulation network, FM outlets, mixed outlets.

For different types of outlets to measure the Parameters are different. For amplitude modulation network, it is necessary to measure dot percentage, network cable number, net angle and so on, and the FM dot and mixed dot only need to measure dot percentage.

No matter what type of network point, monitoring, dot halo, loss or excessive reduction of the network is very important.

Quality control in printing process After the printing plate. In the printing plate measuring instrument to view the image, you can monitor whether the stolen version, Dot is faint halo.
