Description

A kind of artistic rice paper of micro- spray
Technical field
The present invention relates to a kind of Alhue paper.Specifically carried out using the micro- jet printer of polychrome used in arts reproduction A kind of rice paper of coating.
Background technology
With the fast development of modern print reproduction means and digital technology, the art work starts largely to carry out high emulation Duplication and batch production, be formerly only available be stored in museum rare works start in the form of duplicate enter people life It is living.2004, Seiko Epson Corporation started the Giclee technology of art of advertisement product duplication, the popularization of the technology, becomes high-end The important means of arts reproduction.Micro- artistic rice paper of spray is the one of which carrier that handicraft duplication is carried out using micro-spray technology, And the important component of high imitative handicraft.Artistic rice paper is mainly used in the Gao Fang of ancient Chinese painting and calligraphy and modern painting and calligraphy Replicate, it is desirable to be capable of color, level, details, the style of writing of accurate reductivism product original work, and lightfast antioxidant, collect and hold Wait so long feature.Artistic rice paper requirement for micro- spray has high color density, and broad colour gamut, uniform, stable and consistent color is again It is existing, good grey balance etc..
The height of the art work is imitative to be replicated and be particular about " primary colors, former big, protoplasm ", all it is to be used as standard closest to original work.It is adapted to It is close with surface that traditional rice paper is coarse and texture in the rice paper of Giclee printing, its paper.The artistic rice paper master of early stage The ground such as Japan, South Korea, Taiwan are come from, because it holds at high price, the current country also begins to voluntarily produce micro- spray art Rice paper, with the expensive imported product of fictitious hosts.However, the production technology of the domestic product is ripe not enough, also, due to In characteristics such as the coarse surface of the rice paper body paper of coating, high water imbibitions, also cause the more difficult control of coating quality.Main table Now color density is low for printing, not enough uniformly (printing spot occur), color reprodubility be poor for color, colour gamut not enough extensively, pattern level The problems such as sense is poor, details performance is bad.For example, some domestic papers easily go out in the pattern of the color of large area printing list one Now print spot, and print pattern stereovision is bad, details does not reflect the problems such as coming, and the art work of printing can be caused overall Class is not high;Meanwhile the coating apparatus of the domestic production product is also relatively backward, coating accuracy is low, and production control is unstable, makes Fluctuated into product quality, it may appear that during the Paper Printing of same pattern different batches, color is inconsistent, aberration, color density occurs Unstable, its product is only used for low-grade arts reproduction, and the arts reproduction of medium-to-high grade time still selects imported product.
The artistic rice paper of micro- spray has similar printing requirement with Conventional color Alhue paper, close if any high printing color Degree, wide colour gamut, quick blotting speed, good color fastness, nothing are spread and sunk in and oozed, without characteristics such as flashes.However, conventional color jet-ink Printing paper can not replace the artistic rice paper of micro- spray.From texture, two kinds of paper significant differences, color ink jet printer paper It cannot be used for the imitative duplication of height of the art work.In order to pursue the texture of traditional rice paper, artistic rice paper is typically with traditional rice paper For body paper, it is coated on its surface.Compared with body paper used in color ink jet printer paper, rice paper body paper surface is substantially coarse, paper Face gap is thick, and porosity is high, and more open, the water imbibition of rice paper body paper also apparently higher than color ink jet printer paper body paper, When this also make it that rice paper body paper is coated with, it is uneven easily to there is adhesive in uneven absorption, coating skewness, coating The problems such as migration, so that the artistic rice paper after coating uneven blotting speed, layer of ink skewness, ink occurs when printing The problem of layer Density inhomogeneity (printing spot occur) etc. is fatal.Conventional color spray dope viscosity is low, generally in pressure permeation and hair , it is necessary to which continuous phase part is moved in paper in wet coating under thin absorption, cake layer is formed, so that air knife is measured, this For the very strong rice paper body paper of absorbability, according to color spray coatings, also it is easy to above-mentioned fatal problem occur.Institute So that the production technology of Conventional color Alhue paper is not appropriate for the production of high quality art rice paper.
At home, some producers have applied for the patent of micro- spray rice paper, such as patent " letter of credence in digital micro jet high simulation replication The method of rice paper and tiffany is coated with picture " (application number CN200810116778), in provide it is a kind of suitable for micro- spray Gao Fang's The manufacture method of rice paper and tiffany is coated with, the method first applies one layer of glue, then coating, and this method is single paper coated processing, should Method can not meet the requirement that continuous coating production is carried out on the mechanism rice paper of entire volume, be not suitable for large-scale industry metaplasia Production;Patent " scroll rice paper for copying artwork and its manufacture craft " (application number CN201210577467), there is provided Yi Zhongshi The technique for closing industrialization quantity-produced spool rice paper, the technique are only to solve single paper coated not forming extensive industry Change operation, during production costs, laborious, cost of manufacture is high, and quality is difficult to reach the simulation requirements that industrialization carries out arts reproduction The problem of, the problem of existing when not applied to micro- spray of above-mentioned domestic production with rice paper, solves;Patent " inkjet printing The method for penetrating and coating of material " (application number CN 200710063661) and patent " inkjet printing coating and are made of the coating Ink-jet typing artificial material " (application number CN200710063662) individually disclose a kind of coating method of ink-jet printing material With a kind of inkjet printing coating and its manufactured ink-jet typing artificial material, beaten with solving traditional rice paper or silk paper in color jet-ink On print machine the problems such as produced serious ink diffusion, poor contrast and color saturation difference.What this two patents solved is to pass Produced problem when system rice paper or silk paper print, the micro- spray for not solving current domestic production is existing when being applied with rice paper to ask Topic.Meanwhile this two patents are suitable only for single paper coated, its stability is poor, is not suitable for industrialization continuous production;Patent is " a kind of Ink jet recording paper " (application number CN200810225556) and a kind of patent " highly artificial material for jet ink printing " (application number CN200810225553 a kind of material of suitable inkjet printing) is individually disclosed.A kind of its Patent " high emulation material of inkjet printing Material " discloses silk paper and silk, is not related to inkjet printing rice paper, and patent " a kind of ink jet recording paper " also only solve due to The ink that print substrate blotting speed occurs slowly interpenetrates, and influences the print quality problem of pattern resolution, does not solve The problem of micro- spray of domestic production at present exists when being applied with rice paper;Patent " ink-jet typing artificial material " (application number CN201120402556), the ink-jet typing artificial material of the utility model can solve traditional rice paper or silk paper in color jet-ink On printer the problems such as produced serious ink diffusion, poor contrast and color saturation difference, do not refer to that solution is current The problem of domestic micro- spray exists when being applied with rice paper.
As can be seen here, the rice paper of the suitable Giclee printing of domestic production at present, occur during application as:Print color Not uniform enough (printing spot occur), color reprodubility is poor, colour gamut is not wide enough, pattern stereovision is poor, details shows bad etc. ask Topic;Production control is unstable, causes product quality to fluctuate, and during the Paper Printing of same pattern different batches, color differs Cause, the problems such as aberration occur, still without good solution.The presence of these problems, and restrict the high-grade art in China Product replicate and move towards a high-end bottleneck problem.
The content of the invention
Patent of the present invention provides a kind of artistic rice paper of micro- spray, and artistic the rice paper coating and coating porosity are evenly distributed one Cause;During printing, blotting speed is fast, uniform, and when great Mo amounts solid color (especially black) prints, color uniformity will not There is printing spot problem (i.e. due to uneven blotting, the local color density and color distortion of appearance);Print pattern entirety color Density is high, colour gamut is wide, high resolution, and can obtain preferable tone reproduction, so that print pattern stereovision is good, pattern is more Close to original copy, realize that the art work of top grade is copied.The artistic rice paper uses high-end coating apparatus, and combines advanced coating work Skill is produced, it is possible to achieve stable production control, so as to obtain stable product quality.
