The method of coating rice paper and tiffany in the digital micro jet high simulation replication Chinese Painting and Calligraphy
Technical field
The present invention relates to be coated with in a kind of underway state ancient calligraphy and painting digital micro-spray emulation copy coating, adhesive and the coating process thereof of rice paper or tiffany.
Background technology
The successive dynasties calligraphy and painting art of China is the wonderful work of world art, the representative of Chinese traditional culture, and stock's successive dynasties painting and calligraphy have reached hundreds thousand of in the present museum both domestic and external institute, wherein, lay aside and neglect because of the oxidation of of the remote past, air mostly.As the carrier of Chinese culture, the value of its existence is that numerous people institute is cognitive, appreciates, and should worldwide carry forward, and also is simultaneously our Chinese offspring of education, exchanges the requisite material of various countries' culture succinct.Otherwise it only is collection that the purpose of painting and calligraphy collection has become, and does not have its functions peculiar of fine performance.Therefore; The contradiction of " hiding and exhibition " becomes the huge bottleneck of present collection painting and calligraphy career development, and the contradiction focus of " hiding and exhibition " is in " exhibition ", and what is the purpose of " exhibition "? To make the original works material object everybody obvious to all? Still show the intension essence of original work; Let cultural essence let everybody understand? Undoubtedly; Be the latter, be presented in face of the modern visitor, just reached the basic goal of putting on display as long as cross over the ancient civilization carried in thousand years to treasure.
Cleaned up this elementary sentence, we will study sight and be placed on Chinese Painting and Calligraphy emulation copy technology.It becomes the hope of Chinese Pavilion collected books picture from " minority " trend " masses ".
China at present existing a lot of clone methods, like wood-block printing, collotype printing, polychrome hectographic printing etc., and these methods have mostly selected coated paper or offset paper for use, rather than rice paper or tiffany, and the emulation degree is poor.Occurred printing ink coated mesh point printing on rice paper in recent years, and enlarged colour gamut through many specially looks, the traditional Chinese Painting effect of printing off is stiff, loses the especially polishing effect of ink and wash of traditional Chinese Painting, is difficult to popularize and adapt to modern needs.And the traditional hand that the Palace Museum Department of Science and Technology is adopted is copied copy of ancient painting and calligraphy (being confined to strong color drawing painting) and the photocopying ancient book is drawn (being confined to ink and wash), and only can accomplish about 20 every year.
2005 " Giclee " beginning is promoted in China." Giclee " manufacture skill is perfect, and the image precision is high, real colour, levels are rich, third dimension extra-heavy, color stable, special-purpose pigment and support material.Owing to receive the restriction of Chinese Painting and Calligraphy material characteristics; The support material that Giclee adopts when duplicating Chinese painting has: textile medium of anacidity and machine are made imitative rice paper; Like the ultra level and smooth art paper of Epson, weavy grain art paper etc.; The difficulty of replicating vector can't realize real breakthrough all the time, attempts adopting rice paper and tiffany even part is duplicated, and its color also can't reach effect true to nature.
In sum, printer both domestic and external has carried out unremitting effort for the art work of high emulation duplicates, but receives the restriction of technology; Its technical difficulty is big, complex process, and fabrication cycle is long; Cost is high, also has some imperfect parts, remains further R and D.
Technology contents
The present invention relates to be coated with in a kind of underway state ancient calligraphy and painting digital micro-spray emulation copy coating, adhesive and the coating process thereof of rice paper or tiffany.
The concrete scheme of present technique is:
1, the digital collection of duplicate object
At first using " digital acquisition technique " or " positive sensitization " gathers the painting and calligraphy pieces that duplicates.Employing silverfast (flying the spy) directly to the original paper scanning shoot, obtains the RGB digital document up to 200,000,000 pixel digital cameras; Or original paper taken pictures become 8 * 10 sensitization positive, be converted into the RGB digital document through electric separation machine, with the RGB original work digital picture input computer that obtains, the colour gamut contrast original paper that makes full use of the RGB of image is mixed colours.
2, replicating vectors such as rice paper or silk scroll itself are done the face coat technical finesse
This coating agent contains: silica, and volume accounts for 20-30%; The nano grade titanium white powder, volume accounts for 20-35%; Water, volume accounts for 20-30%; Resin glue, volume accounts for 15-25%.Be furnished with adhesive in addition, this adhesive respectively accounts for volume 50%, 25%, 25% by methylcellulose, animal glue, alum and constitutes.
This coating agent specific area is big, and surface adsorption power is strong, and surface energy is big, and aspects such as chemical purity is high, dispersive property is good, thermal resistance, resistance have special performance, have superior stability, reinforcement property, thickening property and thixotropy, the transparency.
The method for using of coating:
(1) selects rice paper and tiffany according to the support material of original paper.
(2) first pass glue-line: be coated in uniformly on the support material adding the water-reducible adhesive of 50% volume, dry for use.Support material after doing still keeps primary characteristic.
(3) be evenly coated in coating agent on the support material after drying.Last wall stretches tight to put down and dries.This moment, the rice paper and the tiffany of coating completed.
3, be implemented in the emulation copy on rice paper and the tiffany through digital micro-spray technology
(1) on coating rice paper and tiffany, sets up the RGB transfer curve that is fit to the Chinese Painting and Calligraphy standard.
On coating rice paper and tiffany, use MatchPrint color management software analysis Chinese painting color, the distinctive colour gamut of tone, and the performance that had of rice paper, the unique material of tiffany, generate the ICC data characteristic curve that is exclusively used in Chinese painting information.Through the test of Monaco profiler vitta, levels are rich has improved the density of little ink-jet look of rice paper and tiffany, has also reduced gradation more exactly.Rice paper and tiffany polymeric coating layer technology have solved admirably utilizes Giclee on rice paper, tiffany and the canvas of drawing usefulness, to carry out the difficult problem of high emulation copy
(2) after employing paper and the tiffany polymeric coating layer technology, guaranteed the realization of Giclee characteristic on rice paper and tiffany.
The described Chinese Painting and Calligraphy emulation copy of present technique printing technology; Through one section cooperation with Palace Museum and the contemporary experts of calligraphy and painting of part; Proved these technological means of this technology, this technology is on the basis of inheriting tradition, through merging science and technology such as computer software, chemical materials, digital micro-spray; Make through special Chinese Painting and Calligraphy of duplicating, reach highly consistent, remarkably true to life with original work.Its maximum characteristics clench the characteristics that Jiao, dense, heavy, light, clear five variable concentrations mass colours show traditional Chinese Painting " with Mo Weizhu " exactly.Simultaneously again with the national painting characteristic of " thick but not greasy, light and quite well " bright and clear, calm, simple and honest, soft being embodied most vividly in the traditional Chinese Painting " is auxilliary with look ".
