If you have this kind of material around you, you can easily draw all kinds of necessary traces with a little hard drawing with a ballpoint pen or other hard tools. The finished version is rolled up with ink or painted with color, and then coated with paper for printing and painting, which is what we call blow-molded paper prints. After learning this kind of printmaking, students can freely express what they see, think and hear. It will definitely realize your dream of learning printmaking.
Second, water pink blow-molded paper prints
Simply put, gouache blow-molded paper printing is the material of blow-molded paper, which is a kind of hand-printed color printing, referred to as gouache blow-molded paper printing. It is to lightly press the required marks on it with various hard instruments, and then apply various advertising colors or water pink with a brush to cover the paper. Blow paper is very soft. When a ballpoint pen is used to draw on blow-molded paper, dots, lines and surfaces with different sizes and widths can be left on the surface, which can produce colorful printmaking effects. Gouache pigment (or concentrated advertising package) can be operated independently instead of ink and cleaned after class.
Four, tool materials:
Blow-molded paper plate, pencil, ballpoint pen, hand knife, printing paper, writing brush, several oil painting pens, white latex, gouache, color mixing box, clip, No.240 water sandpaper, a piece of cotton cloth, a towel and a small bucket.
Five, buy blow-molded cardboard should pay attention to the problem:
Generally, the size of blow-molded paper we buy is 1 14cm×45cm. When making paper prints, we should cut the paper into various sizes according to our own needs. Divided into single layer and double layer, the main difference is that the single layer is fine and the double layer is rough. Remember to choose a thicker single-layer blow-molded paperboard, which is the key to determine the success or failure of the printing effect of the work.
Six, the production of powder printing blow-molded paper prints must first do one thing:
There is a layer of oily substance on the newly bought blow-molded paper plate, while the powder-printed paper plate uses water-based pigments, which will cause water droplets due to oily separation when drawing the board. Therefore, in order to achieve the best printing effect, it is necessary to treat the surface of blow-molded paperboard before plate making. Gently polish the entire surface of blow-molded paper with 240 # water sandpaper, or wipe the entire surface of blow-molded paper with sponge dipped in soapy water. When you use any of the above methods to process a printing plate, colors can be easily attached to the page.
Sketch (of a painting)
Draw a manuscript according to your own life experience (or sketch) (such as campus life, rural customs, etc.). ). When drawing, the teacher should talk about the density relationship of the lines that make up the picture: in the picture, where are the densest lines, where are the thinnest lines, and where are the densest lines (that is, the relationship between black, white and gray that make up the picture). In the middle and lower grades of primary school, we don't directly talk about the "black", "it" and "gray" that make up the picture.
Cutting block for printing
Draw the manuscript directly on the blow-molded paper with a foam watercolor pen, and wipe off the dissatisfied parts with a wet cloth. After painting, use a ballpoint pen (bamboo sticks, nails, etc. ) It's hard to describe. Because the blow-molded paper is soft, the ballpoint pen marks it as a dent. Dense lines will be forced to sag to form concave blocks, and sparse lines will form gray.
Roll gouache pigment (or concentrated poster color) back and forth on the flat plate with glue gel, so that the surface of the glue gel is evenly inked (it is not advisable to add too much water to the pigment, so that it should have a high concentration), and then rub it on the rigid plate (various colors can be adjusted as needed), so that the printed matter of blow-molded paper is evenly colored (the color on blow-molded paper should not be too small). There is also a printing method: filling gouache on blow-molded paper with a brush, then printing picture paper with background color in advance on the blow-molded paper, filling in one color and printing one color, and printing the pictures one by one. The printed matter printed by this method is called powder printing, and this method has basically been widely used. Its disadvantage is that it takes a long time to print a picture. The above production methods use blow-molded paper instead of wooden boards, ballpoint pens instead of wood carving knives, and concentrated advertising paint instead of ink, which reduces the production difficulty, shortens the production time of children's maps, and enables students to create printed matter in class, after class and at home.
Performance skills:
Batik effect of rock paintings and murals
(1) Carve the plate according to the expression method of blow-molded paper prints, and tear the plate into irregular shapes by hand according to the needs of the picture.
(2) Rub the prepared blow-molded paper probe into a ball (which can be rubbed locally according to the needs of the picture), and stick the torn part on the back of the blow-molded paper with adhesive tape.
(3) According to the basic expression method of blow-molded paper, printed matter can be printed in monochrome, or partially filled with oil painting rules to form colors (when painting oil painting rules, the force is slightly light, and the original engraved lines cannot be drawn). The version printed in this way is random, which can achieve unexpected results, with a sense of the times and a strong local flavor. When instructing students to create such works, murals and batiks can be provided. For students to appreciate, so as to achieve more ideal results.
Woodcut effect
① Draw the manuscript on blow-molded paper with foam watercolor pen.
② Use a ballpoint pen or other hard pen to carve a small number of slender lines on the blow-molded cardboard of the good draft.
(3) According to the characteristics that blow-molded paper is heated and melted, an electric soldering iron should be used in places with large blank area and high dot and line density in the drawing.
Local heating is carried out on the blow-molded cardboard painting (the tip of the electric soldering iron can be polished into different shapes in advance), and the tip of the electric soldering iron is square or round, so that the produced layout has a strong knife taste. If the picture needs a natural border, you can help me with a knife.
(4) the printing method is the same as before, which can be monochrome printing or color printing. The work has a strong knife flavor and woodcut effect.
The prints made by this method have exquisite artifacts and strong woodcut effect, which overcomes the difficulty of primary school students carving boards with woodcut knives and is suitable for popularization among primary school students, high school students and middle school students. When making plate with electric soldering iron, we should pay attention to controlling the contact time between electric soldering iron and blow-molded paper. This method is suitable for popularization in art extracurricular activities.
Show the painting effect of brick carving rubbings
① Draw the objects to be represented on blow-molded paper (or a piece of paper with rough surface) and summarize them as much as possible when drawing.
(2) Cut out the drawn pattern and paste it on the paper block (or blow-molded paper) with latex.
(3) After the latex is coated, the work is printed (the printing method is the same as before).
The production method of this effect is mainly based on the difference of ink absorption performance of blow-molded paper and paper blocks. The paper block has poor ink absorption, and the printed ink (color) is light, and B has mottled texture effect. Blow-molded paper has strong ink absorption, printed ink (color) is deep, and the contrast between reality and reality is strong, which has strong brick carving and stone carving rubbing effect.
Color printing.
(1) Seal the board according to the basic method of blow-molding paper printing, print the outline of the picture on the drawing paper with deep water powder, and wait (the drawing paper and the board are fixed with clips).
(2) Uncover one end of the drawing paper and fill in the blank space of the picture outline with different water pink. (Water pink should be lighter)
(3) On the L-shape of blow-molded paper, deep water pink printing paper is printed, so as to print printed matter with color shading.
There is also a printing method: first, print a printed matter according to the printing method of monochrome printed matter, and then directly fill the part (background) with a brush after coloring. The prints made by this method have a rich sense of color in the whole picture, which is convenient for children to learn and master.
Seven, other commonly used tips:
1. Monochrome flat coating method: Brush a single water pink color on the prepared board with a brush or a board brush, which is called monochromatic flat coating method. It is more suitable for beginners to practice powder printing and blow molding paper printing.
2. Color separation flat coating method: With the foundation of monochrome flat coating method, you can practice color separation flat coating method. Color separation and flat painting refers to the method of painting by painting several colors on various parts of the picture respectively. It is characterized by rich colors, beautiful appearance and certain appeal.
3. Light-shade discoloration method: Light-shade discoloration method refers to the method of mixing one color with another color and printing it on blow-molded cardboard. This method is suitable for large area images.
Eight, coloring should be paid attention to:
1. When using black cardboard, the colors should be bright, brown, plum, dark green and deep red. It should be used as little as possible. When dark color is used, some pigments such as white powder and lemon yellow should be added appropriately to make the contrast between color and black cardboard strong and eye-catching.
2. grasp the moisture when painting. If it is too dry to print, if it is too wet and the color is too light, you can see the black paper tray, and the whole picture will be in a mess.
3. Color and print at the same time, otherwise the pigment will not be printed on the paper plate after drying for a long time.
4. The printed paper and the prepared blow-molded version must be firmly clamped by two clamps to avoid displacement. Don't take off the printing paper until a picture is printed.
