People are increasingly interested in the collection and appreciation of calligraphy and painting, and are especially passionate about ancient paintings, famous paintings and authentic calligraphy. However, the genuine product is often only one piece, and its price is expensive, ranging from thousands of yuan to hundreds of thousands of yuan. How can people satisfy this desire? Only high-tech means is used to print high-quality, high-quality artificial paintings and calligraphy on Xuan paper. The price of batch screen-printable paintings and calligraphy is 1/10 ~ 1/100 lower than the original, and the surprising quality and price will make fans enthusiastic.
One of the characteristics of screen printing is the "thick ink layer". Therefore, screen-printing calligraphy is the most suitable. Making a few more screens in the shaded area can achieve the effect of being fake. The screen printing calligraphy process steps are as follows:
1. Black source
â‘ The calligraphy of books and periodicals can be sent to the printing factory to process the positive film.
â‘¡Sample calligraphy of prints can be enlarged with the magnifying ruler tool, or "Jiu Gong Ge" can be used to enlarge according to the scale requirements. People with no skill in calligraphy can also accurately enlarge the calligraphy fonts.
â‘¢ The original Xuan paper calligraphy works without mounting, and is used as a negative film for direct photosensitive plate making. Due to the poor light transmission line of rice paper, the exposure time in plate-making is longer than the conventional one by 1/2.
â‘£ The original calligraphy is framed and can be copied by a copier. If the font on the copy paper is not dark enough, fill it with ink and apply a layer of ink. Copy paper is far less light-transmissive than film, and the exposure time in plate-making is also doubled than conventional.
2. Screen production
â‘ Select 150 ~ 200 mesh wire mesh cloth.
② Wooden frame or aluminum alloy net frame (size 150 × 50cm), use manual or mechanical net stretch.
â‘¢Adopt direct photosensitive plate-making method, diazo photosensitive latex is water-based, scrape as many times as possible when applying photosensitive latex, it is best to use Beijing Xinya U49 thick film photosensitive latex, suitable for screen printing thick ink easy to penetrate into rice paper .
3. Printing material preparation
After dissolving 1 part of CMC (methyl cellulose) and 10 parts of water, and then adding Binaer (fixing agent) and ink or Chinese painting pigment, it is most suitable for printing works such as calligraphy and Chinese painting. The effect of screen printing calligraphy can smell ink fragrance.
4. Paper product selection
The traditional paper used for calligraphy is Xuan paper. The quality of the paper should be pure, white, dense, moist, loose and tough. The performance of Sheng Xuan paper is easy to absorb water and easy to permeate. It can provide a sensitive record for the movement of flexible brushes and provide a broad space for the emotional expression of pen and ink. Therefore, screen printing calligraphy should use "sheng xuan" paper.
5. Printing process
â‘ "Painted felt" is spread on the screen printing plate, because the performance of raw rice paper absorbs water, permeates, and the ink easily leaks during screen printing, and the paper gets on the platen and directly destroys the literal effect. Therefore, the wool felt is placed under the rice paper. Because the fluff on the surface of the sheep felt lifts the rice paper, there is a layer of air cushion under the paper. The moisture in the ink color will not leak, adhere, and affect the printing quality.
â‘¡The squeegee should be 2 ~ 3cm larger than the screen. In order to leak more ink, the front end of the rubber strip of the squeegee should be U-shaped or small rounded.
â‘¢ Before printing, it is best to spray a thin layer of water on the rice paper to promote the ink to quickly penetrate into the rice paper.
④When scraping by hand, the scraping direction is opposite to the ink return direction, and the angle between the strip and the screen is 30 ° ~ 75 ° during scraping. Scratch the print from a distance into the arms, and push it from the arms to the distance when returning the ink. The angle is relatively random, mostly 45 °.
⑤ Calligraphy paper products printed on the screen only need 15 ~ 30min to dry, and then sent to the calligraphy and painting mounting shop for mounting.
During the holidays, people are used to reorganizing the living room, and then carefully select some paintings. This can not only embellish the space, balance the layout, coordinate the colors, and beautify the room, but also cultivate the sentiment and give people the enjoyment of beauty.
