Long printing group to teach you how to choose the art of paper printing and ink

Due to the art of paper on the raw material and papermaking technology has certain particularity, so art paper with ordinary paper on paper structure and performance have bigger difference, the selection of printing ink and printing process has different requirements.On the choice of printing ink and should pay attention to the following three points.

One, pay attention to the art of paper absorbency

Different art paper on ink absorption of the sex difference is very big, such as the cup mat board easily absorb ink, leni riefenstahl paper ink absorption, more easily and is hard to suck the ink such as vegetable parchment.In printing ink absorbency is directly related to the quality of the 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 the paper have a lot of influence on absorbency.Some paper texture is relatively thick, ink can easily penetrate into and dry;While some quality of a material is very close, ink on paper surface, such both neither are easier to penetrate into the paper, are less prone to dryness.

Second, focus on art paper smoothness

Because of the differences in the papermaking process is different on paper, art paper, such as some paper relatively thick, smooth degree is low, some relatively close, smoothness is higher.Such as printing more thick art paper, printing pressure shoulds not be too large, otherwise it will damage the class art paper background apparent characteristics, and result in deformation of the paper.On the other hand, if is relatively close art paper, printing material should be appropriately increased printing pressure.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.If to ink printing, pay special attention to control printing pressure.

Third, pay attention to some other characteristics of art paper

Art paper and plain paper does not have characteristics, such as texture.We know, paper is flat material, can through the graphics of visual sense, let a person feel material such as stripes, background of design and color is designed using the people visual sense.In packaging and 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 the design of printing, using rough and texture and shining paper is a kind of very important texture design.On the rough texture of the art of paper 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 texture (texture).Skin texture has a natural texture and texture, variety of art used in the printing paper is through the manufacturing process for processing and texture.Texture visual texture and tactile texture.The texture visual texture is a two-dimensional plane.Tactile texture usually by consolidation pressure, die cutting, carving processing way and get, is a three-dimensional texture, with the hand can touch feeling.Art paper is better than plain paper texture and texture, no matter from macroscopic or microcosmic world provide plenty of material for packaging design, etc.For these art paper, should try to use the essence of the paper, use less ink printing (especially large area printing), and pay attention to control the printing in the printing pressure.
