There are many types of printmaking. I wonder if students know what blowing plastic printmaking is?

If you want to learn to blow plastic prints, there are skills. Come and see the techniques of blowing plastic prints!

1. Tools and materials for blown plastic printmaking: Materials and tools used for platemaking include: blow molding paper (single piece), colorless ballpoint pen, scissors, pencil, foam watercolor pen, electric soldering iron, etc.

Tools and materials used for printing include: gouache advertising paint, white latex, rubber rollers, gouache, oil pastels, plywood, paper, buckets, clips, etc.

2. The production process of blow molded paper prints: 1. Create manuscripts: Students use red drawings to draw up a draft with pencil according to their own creative intentions or according to the instructions of the teacher’s homework content. When drawing the draft, the teacher combines examples and narrates

Composition and the density relationship of the lines that make up the picture: where in the picture are the sparsest lines, where are the densest lines, where are the strips of paper neither sparse nor dense, and pay attention to the artistic changes in size, length, and straightness of each other.

.

2. Post-draft: First rub the blow molding paper used for engraving with a dry cloth to make it dull and easy to color. Then use a foam watercolor pen to draw directly on the blow molding paper to remove the poorly painted areas.

, you can gently wipe it off with a wet towel before painting.

When painting, you should start from the top of the blow molding paper to avoid blurring the lines of the foam watercolor pen with your palm.

3. Plate making: Use a colorless ballpoint pen to trace along the handwriting of the manuscript. It must have a certain depth and carve out the outline of the manuscript. Pay attention to the lightness of force when scribing. It is better not to draw through the blow molding paper, because the blow molding paper

The texture is relatively soft, and the colorless ballpoint pen will form dents after being scratched. Where the lines are dense, dents will form when pressed hard, and where the paper strips are sparse, gray will appear.

4. Printing: First place the gouache advertising paint on a flat plate, roll it back and forth with a rubber roller so that the rubber roller receives the color evenly (note that too much water cannot be added to the paint), and then roll the color onto the engraved blow molding plate.

(Various colors can be mixed at will according to the needs of the picture), so that the blow molded paper prints can be evenly colored.

(Be careful when rolling on the blow molding plate. Slowly roll in one direction from bottom to top, then from right to left in a cross shape. Do not roll back and forth, and do not use excessive force).

Finally, cover the blow molding paper with drawing paper or rice paper, and press with a little force with the palm of your hand or a dry cloth. When you feel that the printing is almost done, you can lift a corner to see if the printing is done. If the printing is not true,

You can roll in more color where the color is lacking. If the printing pressure is not enough, you can lay the paper plate flat and continue to erase the printing until you are satisfied.

3. The expression of the texture effect of blow molded paper prints: Children's paintings are characterized by exaggeration and deformation, but students in senior grades often feel that they are not good at painting and cannot correctly understand the beauty of exaggeration and deformation of objects. Teachers should use methods to

Encourage and guide primary school students to paint boldly, and use a variety of different methods to express the various print effects of blow molding paper paintings and prints, effectively improving primary school students' painting (1) and the expression of the pointillism effect of strong-colored oil paintings.

1. Place the processed blow molding paper prints on the plywood, use slightly larger printing paper (black or white) to cover the blow molding paper, and then use a clip to secure one side of the printing paper and the blow molding paper plate so that

Color registration is accurate.

2. Open one end of the printing paper, use water pink, and apply it on the various areas that have been painted on the blow molding paper (a sponge can be used for large areas of production color). For each color, make a rubbing until it is completed.

The effect of this kind of printmaking is to use the powder printing method of first darkening and then lightening, using shallower to press deeper, which can give the picture a deep, rich and durable oil painting effect.

Instruct students to pay attention to the relationship between color and color when making rubbings, and control the amount of coloring to achieve the desired effect.

(2) Expression of the vivid color gradient watercolor effect: 1. First carve a concise outline of the drawing on the blow molding paper, then attach it to the printing paper and clamp it on one side.

2. Wet the towel with clean water, squeeze it dry slightly, cover it on the printing paper to be printed, wet it for a while, and then remove the towel (do not make the paper surface too wet, otherwise the color will bleed out and the picture will be stained.) 3.

Adjust the concentration of the color according to the needs of the picture, then dip a sponge into the color and create a gradient of several colors on a plate (match the appropriate color according to the meaning of the picture) for rubbing. If the effect is not satisfactory, it can be modified repeatedly.

This effect can make the blow-molded paper prints printed according to this method have various picture effects, vivid colors, and the effect of watercolor paintings.

(3) Expression of the effect of woodcut prints: 1. Use foam watercolor to draw on the blow molding paper, pay attention to the density of the paper strips in the picture, and use black to draw the relationship between black, white and gray.

2. Use latex paint to stick the drawing on the plywood, and use a colorless ballpoint pen to draw a small number of slender lines on the blown paper plate of the finished drawing.

3. The larger blank areas and dense dots and lines in the layout are heated locally on the blown paper prints with a special electric iron according to the needs of the picture, and the sparse areas are described with a colorless ballpoint pen.

4. Printing, use a rubber roller to color it and print it into a single color print, or use water chalk to color it and print it in color.

The works printed by this method have a strong knife flavor and the effect of woodcut prints.
