Graphic design of books and texts should be standardized

At present, with the technological advancement of printing companies, the overall level of quality of books and journals has been greatly improved, and some products have also reached a higher level of quality. However, in the examination and determination of a large number of books and products, it is found that some products do not have a standardized graphic design, which leads to problems in product quality and affects the overall quality of books and periodicals.

The technical design of books and texts mentioned here is not standardized (unreasonable), including the process design of the publishing department and the process design (secondary process design) of the printing factory is not standardized.

The author learned that in participating in the inspection and certification of high-quality products (first-class products) of the Press and Publication Administration, the authors learned that among the large number of unsuccessful products, the problem of non-standard graphic design is more prominent, and the quality of the product is greatly reduced. For example, the army sent the Department of Excellence to detect failed products. In 2000, the products submitted for inspection were 728 varieties, and the products that were dropped (preliminarily determined) were 195 varieties. In the lost products, the graphic arts design is not standardized and occupies a considerable proportion, reaching 46.15% (including the non-standard molding process).

The problems with the non-standard design of common graphic and graphic arts are:

1, books and magazines are not uniform design of the heart position, resulting in incision, set mouth size, head, foot size, and outside the white version of the core size is not standardized, making individual page number, Shu Mei Yu, Shumei line was cut off, leading to product quality problem.

2, color illustration page, mouth, cut size is too small (less than 2mm), or did not set aside the mouth position, bound into the book when the book set in the order of the mouth, seriously affecting the use of reading.

3, the text of the illustrated text and the design of the figure from the up and down the distance is not reasonable design, some spacing is too close (less than 2mm), and some too far (about 7-8mm or more), affecting the description of the text neat. If it is the use of drawing and lying figure process, when the description text is too close to the drawing edge (less than 3 mm), it is easy to pad when printing, resulting in the quality problem of incomplete flowers and edges on the drawing edge.

4. The cover, seals, seals, seals, and illustrations are too close (only 1-2mm) away from the incision (or mouthpiece). This design is not only difficult to see, but may even be cut, seriously affecting the finished product. Quality and beauty.

5, cover, cover four "color" design and the actual thickness of the book does not match, after binding into a book, "Qi color" is not uniform, and some out of more than 2-4mm, it directly affects the overall design of books and periodicals Aesthetic effect.

6. The depth of the background color of the flat book used for the heading and head flower of the same book has a direct impact on the decorative effect and product quality of the book.

7, anti-white pressure inscription design flat net background is too shallow (net area less than 40%), easy to mix with text after printing, difficult to distinguish, affect reading.

8, black (various dark) pressure map inscription design flat net background too deep (above 60% area), after the printing of words and background color can be mixed, affecting reading.

9. In the text, the background color in the field is irrational (100% dot area). The background color of the printed products must be uneven. It is easy to print through, pull the paper, and stack the ink.

10. The hollow white strokes in titles of books are too fine to be reproduced after printing, and they will inevitably lose their artistic effect.

The above-mentioned quality problems in books and periodicals are mainly due to the non-standard handling of graphic and graphic design and printing business managers (production scheduling). Therefore, the specific conditions (printability) and possible process capabilities in the printing process are used to standardize the process design so as to further improve the overall level of printing and printing. The specific approach is:

1, the layout of the heart position should be unified (except for special requirements), to ensure that the book's incision, set the mouth size, days head, foot size, version of the heart outside the white edge size and other uniform. When the size of the printing plate is fixed, it cannot be arbitrarily changed in the printing plate (imposition) to ensure the correct process design.

2. The setting of the illustration page (white edge) should leave 12mm when there is no special requirement, and 3mm should be left for the incision.

3. The distance between the explanatory text and the margin of the illustration in the text of the body of the book should be 3-5mm. The descriptive text of vertical and horizontal typesetting should be equal to the distance between the sides (left, right and top and bottom) and cannot exceed the width of the diagram. If there are more characters in the description word, it can be arranged in two lines, three lines..., and keep the line spacing and the spacing with the text.

4. The distance between the cover and seals, seals, seals, seals, and illustrations should be 5mm to avoid cutting off the errors when binding.

5, cover, cover the design of the "color" (cover and spine, back cover and spine different colors) should be consistent with the thickness of the book, to prevent binding after the book appears "color" uneven defects affect the appearance of the book.

6, the same book titles, head flower used flat net background, should use the same percentage of the net as the bottom, to prevent the emergence of deep disparities. When printing paper, 100-120 mesh screens are available, and 150-170 mesh screens are available for coated papers.

7, black (dark) pressure map inscription lined flat net dot area should be controlled at 20% -30%, not only can play a good decorative effect, but also conducive to the clear appearance of the text.

8. The flat screen of the anti-white pressure plot inscription should have more than 60% of the dot area to ensure clear text.

9. The decorative background of the cover, seals, seals, seals, and illustrations should be plain and impermeable. If there is no special requirement on the ground background, you can use the coarse mesh line of about 80% of the area network to replace the ground background. This will not only keep the background flat, but also prevent dirty, dirty, brushed, and piled inks. Dirty plays an important role.

10. When using the hollow words in the titles of books, the white strokes of the hollow words should be widened to prevent the white strokes from sticking to the print and affecting reading.
