The
own characteristics of art paper determine that in the field of book printing, it is not to reproduce
the value of the product mainly in print and text, but to make full use of the
unique 61 colors and patterns of art paper itself, and then make proper design.
The unique gloss and color difference of art paper will give people different
feelings. In combination with the design of these different paper, the designer
needs the designer to carry out the originality, use the personality of the art
paper to convey the design intention, make the character of the paper a part of
the design, and perfect the style of the design, so as to show the unique
artistic effect. In the pre-press design, we should pay attention to the
following points.
1.
Choose the appropriate art paper according to
the characteristics of the product.
At
the time of design, we should make full use of the emotions and emotions
expressed by the original lines and colors of the art paper. Through the simple
design of the finishing touch, the artistic effect of simple and beautiful is
achieved. Therefore, sometimes it is not necessary to reproduce the effect of
the product with a large area of printed graphics, which saves printing costs
and reduces costs. For example, the choice of colorful art paper, according to
the characteristics of the product with the appropriate ink, so that the ink
and paper color to form a strong contrast, to attract the attention of the
customers.
2.
Understand the yarn quality of art paper and
consider the stiffness required for product packaging.
Effective
use of art paper strength, toughness, stiffness and elasticity better features,
increase the appearance of packaging products appearance, enhance product
quality. In the design of cartons, it is often necessary to mount ordinary
paper and art paper. The usual practice is to make the plain paper lined with
the vertical direction of the art paper perpendicular to each other to increase
the stiffness of the carton.
3.
The use of special post printing process
Major
use of embossing, UV polishing, hot stamping and other processes. Because of
the high content of long fiber in art paper, it has good stiffness and
toughness. It is suitable for pressing and concavo convex processing, so as to
improve the artistic effect and grade of products. A lot of art paper has a
rich texture and special sense of texture, which can make use of this feature
to make a sharp contrast with the gloss produced by the UV light to achieve
special artistic effect.
4.
Selection of printing methods
If
the product needs bright colors and thick ink layers, screen printing should be
considered. But if you want to get a sense of transparency, you should consider
using offset printing. The choice of printing mode will have an important
impact on the final effect of the product.
5.
Selection of printing ink
Many
customers, in pursuit of gorgeous appearance, will use silver ink and gold ink
to print. Generally speaking, gold or silver ink is used mainly in the field or
on the color block. It is best not to design gold or silver for the very small
text of characters and level. In the process of plate making, we should take into account the
arrangement of the color sequence of gold and silver ink, so as to ensure the
metallic color. Also consider the gold and silver ink printing book requirements for art paper. If the art paper has a
strong absorbency to the ink and the connecting material is quickly absorbed,
the metal pigment in the ink will float on the surface of the art paper, losing
its gloss, sticking hard and even falling off. The acid art paper is easy to
react with metal powder, causing the metallic pigment to change color and lose
its luster. When printing gold on art paper, you usually have to make a bottom
ink in the silver ink. For example, a light white ink is laid first when
printing the silver ink. This can improve the gloss of the silver ink layer and
also strengthen the adhesion of the silver ink on the paper. After catalogue printing some gold and silver
ink, some products should also consider UV glazing or Waterborne Glazing or
laminating to prevent oxidation or discoloration of metallic pigments.
