Cooked propaganda is based on raw propaganda, and a layer of alum water is added. If the amount of alum water is small, the so-called half-cooked is derived.
2. The writing is different: the small characters are half-cooked, and the big characters are born.
In fact, as far as calligraphy is concerned, we are also using raw propaganda, half-baked Fully cooked publicity is usually not considered because it basically has no ink permeability.
3. The surface texture and feel are different: raw Xuan cotton is very brittle when cooked, and the elasticity of raw Xuan paper is outstanding. Raw Xuan feels soft in your hand, while cooked Xuan and semi-cooked Xuan feel smoother.
The method of distinguishing raw and cooked propaganda by expanding data;
Due to the different proportion of papermaking raw materials, raw materials can be divided into: single material (thinnest), single clip (thicker), clean skin, cotton material, double clip (two sheets) and three-layer clip. Shengxuan has the characteristics of strong water absorption and is the main material of painting and calligraphy paper. It's better to hide for a long time. The newly made rice paper is too white and feels alive. For a long time, the color of health promotion is soft and the ink color is more charming.
In order to make the new original propaganda achieve the effect of the old paper, the paper can be hung in the air for a period of time, and the treated original propaganda paper is called "wind paper".
Cooked propaganda is a kind of raw propaganda mixed with rubber alum, which has the characteristics of impermeability after water. If dyeing, gold spraying and other processes are carried out, a variety of products can be produced. The main varieties of cooked rice are: vegetarian rice, cooked rice, jade plate, cicada feather, cold gold, tiger skin and so on. Cooked propaganda should not be kept for a long time, which will remove alum and cause local ink seepage.
The quality of promotional materials varies greatly, and the important criterion to distinguish between good and bad is the degree of Mo Yun's exhibition, which is the so-called degree of "moistening ink". High-quality health promotion has the characteristics of "splashing ink, being bold and dripping; Heavy ink, bright and bright; Light ink, distinct layers; The place where ink is accumulated is rich and profound.
The method of testing ink cloud display is generally comparison method, which compares several different raw materials with ink. When testing, the ink should not be too thick, and if it is too thick, it is difficult for the ink color to change slightly.
Because of the different purity and slurryability of papermaking fiber, the different proportion of sulfate pulp and straw pulp, the different manufacturing process and the different inking effect. After inking, the ink halo is clear and the rising force is even.
The quality of health promotion is poor, the halo cannot be clearly displayed after the ink seeps out, the ink is dim, or the ink permeates unevenly. If you can't show the halo of ink, there will be no Mo Yun, and you can't use it as paper for painting and calligraphy.
Generally speaking, comic books should be publicized to facilitate long-term preservation. Because rice paper is special, it can be durable and not fragile, but it takes a long time to make printed matter with whiteboard paper because there are few fibers and it is easy to be fragile. So it can be concluded that the best comics should be printed on the best rice paper.
