The price of bulk prints and paintings can be 1/10 to 1/100 lower than that of the original. The amazing quality and price will leave enthusiasts excited.

One of the characteristics of screen printing is the “thickness of the ink layer”. Therefore, screen printing calligraphy is the most suitable, and the thick and thin parts are made up of several screens, so that it can achieve real effects. Screen printing calligraphy process steps are as follows:

1. Source of black paper

1 Calligraphy of printed books can be sent to the printing factory for processing positive-picture films.

2 Calligraphy samples of printed materials can be magnified using the magnified ruler tool, or can be magnified using the “9-squares” scale requirement. Those who have no calligraphy skills can accurately enlarge the calligraphic fonts by using the Jiugongge.

3 Rice Paper Calligraphy The original script has not been dragged, and it will be used as the best direct photolithographic plate. Due to the poor light transmittance of rice paper, the plate-making exposure time is 1/2 longer than conventional.

4 Calligraphy originals have been installed and can be copied with a copying machine. If the typeface on the copy paper is dark enough, then use a brush to fill in the ink. Copy paper is far less transparent than film, and the exposure time of platemaking is also increased by a factor of two.

2. Screen production

1 Screen cloth selection 150 ~ 200 mesh.

2 wooden frame or aluminum alloy frame (size 150 × 50cm), using manual stretching or mechanical stretching.

3 using direct photosensitive plate making method, diazo photosensitive emulsion using water-based, in the photosensitive emulsion as much as possible to scrape several times, it is best to use Beijing New Asia U49 type thick film emulsion, suitable for screen printing thick ink easily penetrated in Xuan paper .

3. Printing material preparation

Dissolving 1 part of CMC (methyl cellulose) by adding 10 parts of water, and adding Binaer (fixing agent) and ink or Chinese painting pigment, is most suitable for printing works such as calligraphy and traditional Chinese painting. The effect of screen printing and calligraphy can smell ink. fragrance.

4. Paper selection

The traditional calligraphy paper is rice paper, and the quality of the paper should be pure, white, dense, and smooth. Sheng Xuan Paper's performance is easy to absorb water, easy to infiltrate, can give elastic brush running action with sensitive records, and provide a broad venue for the emotional expression of ink, therefore, screen printing calligraphy should use "shengxuan" paper.

5. Printing process

1 "Painted felt" is spread on the silk screen platen. Due to the hygroscopicity, osmotic and hygroscopic properties of the paper, the ink is easily oozing out through the paper, and it is stained on the platen through the paper, directly destroying the effect of the literal surface. Therefore, under the padding of paper under the rice paper, because the fluff on the surface of the sheep felt uphold rice paper, so that there is a layer of air cushion under the paper, the moisture in the ink will not be exposed, will not adhere, will not affect the print quality.

2 The squeegee should be 2~3cm larger. In order to leak more ink, the front of the squeegee has U-round or small round corners.

3 Before printing, it is best to spray a thin layer of clear water on rice paper to encourage ink to quickly penetrate the rice paper.

4 When scraping by hand, the squeegee direction is opposite to the ink returning direction. The squeegee angle and the screen angle are between 30° and 75°. Scratching from the distance to the bosom, pushing from the bosom to the distance when returning ink, the arbitrariness of the angle is large, mostly 45°.

5 The printed calligraphy paper products need only be dried for 15 to 30 minutes and then sent to the calligraphy and painting decoration shop for decoration.

During the holiday season, people are accustomed to arranging a new room, and then carefully choose to hang some calligraphy and painting. This can not only embellish the space, balance the layout, harmonize the hue, and beautify the room, but also can cultivate sentiment and give people a beautiful enjoyment.
