I. pay attention to the ink absorption of
art paper
The absorbability of different art paper to
ink is very different, for example, cup-cushion board is easy to absorb ink,
lenny paper is easy to absorb ink, and sulphate paper is difficult to absorb
ink. In printing ink absorbency is directly related to the quality of the book printing quality and the drying
time, absorbency of different art paper to printing by adjusting the pressure
and usually add ink additives to control, such as poor for the absorbency of
paper, can properly add drier or used in printing ink uv curing, lest caused by
ink drying too slowly on the back of the phenomenon such as sticky dirty,
imprinting pulverization. Of course, the structure of paper has a great
influence on ink absorption. Some of the paper is loose and thick, and the ink
can seep in and dry easily. Some are very compact, ink floating on the surface
of the paper, so that it is not easy to infiltrate the paper
2. Pay attention to the smoothness of art
paper
Due to the different paper making
technology, there are great differences in paper making of art paper. For
example, some paper is relatively loose and thick, with low smoothness, and
some paper is relatively compact and smooth. For example, when printing
relatively loose and thick art paper, the printing pressure should not be too
large, otherwise it will destroy the obvious characteristics of such art paper
bottom lines, and make the paper deformation. On the contrary, if it is the art
paper with compact printing quality, the printing pressure should be
appropriately increased. In addition, some art paper with embossed effect (such
as the embossed paper) and strip texture effects, such as bamboo paper), for
this type of art paper, try not to use (or less) printing ink, as long as the
use of natural float lines, the paper carry on some simple local processing,
such as pressure bump, UV glazing, hot stamping, etc., to retain and use of the
nature of the base paper, can achieve the ideal decorative effect. When
printing ink, special attention should be paid to control the printing
pressure.
Pay attention to other features of art
paper
Art paper also has characteristics that
ordinary paper does not have, such as texture. As we know, paper is a flat
material, which can make people feel the visual texture of materials through
graphics, such as stripes, patterns and shading, etc., all of which are
designed with the visual texture of people. In catalogue printing, more attention paid to the texture, such as to
make people perceive touch of fun on the surface of the packaging materials,
make a wide range of textures of different art paper (such as embossing paper,
paper brail) has been widely used. In print design, the use of rough and
textured paper is an important texture design. On the rough texture of the art
of book printing can further
strengthen the simple sense, even if in the silk has a subtle effect of concave
and convex at the small print on the paper pattern, also has the very good
visual texture effects. In addition, different materials have different texture
(i.e. texture). Texture has natural texture and processing texture, and the
various art paper used in printing is the processing texture obtained through
manufacturing and processing. The texture is divided into visual texture and
tactile texture. Visual texture is two-dimensional texture. Tactile texture is
generally obtained by means of pressure, die cutting, sculpture and other
processing methods. It is a three-dimensional texture that can be felt by hand.
Art paper has better texture and texture than ordinary paper, and provides a
lot of materials for packaging design from both macro and micro worlds. For
these art paper, the nature of the paper should be used as far as possible,
less ink printing (especially large area printing), and attention should be
paid to control the printing pressure.
