Description

Technical Field

[0001] The invention relates to an oil painting brush and a method for drawing oil paintings thereof. Background Art

[0002] In the prior art, a pointed bristle brush, i.e., a liner, is used to draw the fine parts of an oil painting. The tip of the pointed bristle brush is relatively soft and tapered. In order to control the width of the trace drawn by the tip of the brush, the brush needs to be held in mid-air to control the contact area between the tip of the brush and the painting surface, which is inconvenient to operate and affects the speed of painting. The tip of the pointed bristle brush is a collection of many bristles, and the shape of the tip of the brush is uncertain. During use, the shape of the tip of the brush may change or the bristles may be scattered, making it impossible to continue to use the brush. It takes time to constantly adjust the state of the tip of the brush, thus affecting the speed of painting. The pointed bristle brush depicts the fine parts of an oil painting by painting a color surface instead of a color surface composed of drawn color dots and color lines like a fountain pen. In order to show the transition of the depth of the color of the image on the picture, a gradient must be modulated. There are many different colors in the sequence and the transitional connection is achieved. The whole process is very cumbersome and takes a long time. Therefore, the speed of using a pointed bristle brush to depict the fine parts of oil paintings in the prior art is very slow; in the existing technology of drawing oil paintings, only the color surface produced by a bristle brush or a painting knife is used to express the image of the picture, and the expression means is single; the tip of the pen used to draw pen paintings is very thin, about 0.9 mm, and can only use the drawn color dots and color lines to express the image of the picture, which is only suitable for drawing the fine parts of pen paintings. However, when using a pen to express a large area of ​​dark parts of the picture image, one by one is used to arrange and combine the color lines together, which takes a long time. The larger the size of the pen painting or the area of ​​its dark parts, the longer it takes, so the drawing speed of pen paintings is very slow. Summary of the invention

[0003] The purpose of the present invention is to provide a microporous pen tip paintbrush and a method for drawing oil paintings thereof, which can draw oil paintings with rich expression means and as fine as pen paintings, and the drawing speed is faster than the methods for drawing oil paintings and pen paintings in the prior art.

[0004] The microporous pen tip paintbrush of the present invention uses a fiber pen tip with a microporous structure or a foamed plastic pen tip with a microporous structure as the pen tip of the paintbrush. The micropores on the pen tip are used as a penetration channel for oil paint with fluidity and permeability. The pen tip is a cone with a diameter of 3 mm and a length of 20 to 30 mm. The tip of the cone pen tip is the tip of the microporous pen tip paintbrush. The diameter of the tip of the pen tip is 1.0 mm or less. The other end of the cone pen tip is plugged into a pen holder. The plugging depth is one third of the length of the pen tip. In order to ensure a firm plugging, the diameter of the pen tip plugging hole of the pen holder is 0.1 mm smaller than the diameter of the pen tip plugging position. The pen holder is made of wood, bamboo or plastic. The method of providing oil paint to the brush head is "external smear supply", and the specific method is: mix linseed oil and oil paint on the palette, stir and blend with a flat-bristle brush, and finally make the fluidity and permeability of the oil paint flow smoothly through the micropores of the brush head and penetrate to the tip of the brush head, then use the flat-bristle brush head to dip the blended oil paint and smear it on the brush head of the microporous structure brush head, absorb the oil paint through the micropores open to the outside on the brush head, and the oil paint penetrates to the tip of the brush head through the micropores of the brush head, and then the tip of the brush head contacts the picture or strokes on the picture to transfer the oil paint seeping from the brush head to the picture to achieve the purpose of drawing oil paintings. External smear supply is relative to the color supply method of "endogenous storage supply", which refers to the color supply method in the prior art of connecting a plastic pen tube filled with ink to the brush head and using the ink stored in the plastic pen tube to provide pigment to the brush head. Since the pen tip of the present invention is open to the outside by utilizing the characteristic that the micropores of the pen tip are open to the outside, the color supply method of the pen tip "external wiping supply" can be adjusted, smeared and used immediately. For oil painting, compared with the "internal storage supply" of the prior art, the "external wiping supply" can meet the demand for color changes in the painting process at any time, and can make the color changes of the picture as rich as possible. Since the pen tip of the microporous structure pen tip paintbrush of the present invention is a hard pen tip, the pen tip shape is determined, the pen tip is sharp, and color dots and color lines can be drawn conveniently, so the microporous structure pen tip paintbrush of the present invention can use the drawn color dots, color lines and color surfaces composed of color dots and color surfaces composed of color lines to express the color, shape and fine parts of the structure of the picture image like a pen painting brush.

[0005] The method for drawing oil paintings of the present invention is to use the flat-bristle brush (oil painting brush) of the prior art and the microporous structure pen brush of the present invention to draw oil paintings, and five expression means, namely, the color surface painted by the flat-bristle brush and the color points, color lines, and color surfaces composed of color points and color surfaces composed of color lines drawn by the microporous structure pen brush, are used to express the color, shape and structure of the picture image, and the color surface painted by the flat-bristle brush is used as the basic color layer, and the color points, color lines, and color surfaces composed of color points and color surfaces composed of color lines drawn by the microporous structure pen brush are used to express the fine parts of the color, shape and structure of the picture image on the basic color layer, and the "fine parts" refer to the part that cannot express the changes in the color, shape and structure of the picture image by the oil painting brush with a diameter or width of the pen tip of more than 1.0 mm. According to actual needs, color points and color lines can be drawn on the basic color layer before or after solidification. The color points referred to in the present invention refer to the point-shaped color areas of 1.0 square millimeter or less drawn by the pointed bristle brushes, pen-drawing brushes and the microporous structure pen brush of the present invention; the color lines referred to in the present invention refer to the linear color areas of 1.0 millimeter or less width drawn by the pointed bristle brushes, pen-drawing brushes and the microporous structure pen brush of the present invention; the color surfaces referred to in the present invention refer to the color areas other than color points and color lines painted by the bristle brushes (flat bristle brushes and pointed bristle brushes) of the prior art, and the color areas composed of color points with different density relationships and different overlapping relationships and the color areas composed of color lines with different density relationships and different overlapping relationships drawn by the microporous structure pen brush of the present invention. The following examples illustrate the difference between color dots and color lines used independently and color dots and color lines in color planes: color dots and color lines drawn by pointed bristle brushes, fountain pen brushes, and microporous structure pen brushes are used to express point-shaped and linear images in the picture when used independently, such as exposed nail caps on furniture, dark spots on people's faces, hair, thin lines, etc. In this case, the function of color dots and color lines is the color plane, because they express one or several aspects of the color, shape and structure of the image on the picture; the color dots and color lines in the color plane composed of color dots and color lines drawn by microporous structure pen brushes are different from the color dots and color lines used independently. They are the basic units that make up the color plane and are not used independently because they do not have the function of expressing the color, shape and structure of the image on the picture. For example, a row of oblique short color lines is used to express the dark side of a strand of hair. Each of the color lines is a basic unit that makes up the color plane that expresses the dark side of this strand of hair and does not belong to the color plane.The following explains the difference between the color surface painted by a flat-bristle brush and the color surface composed of color dots and color lines drawn by a brush with a microporous structure pen tip: the color surface with color changes painted by a flat-bristle brush is a single whole, and each color change in the color surface requires different colors to be blended and connected with it. There are as many color changes as there are colors that need to be blended and connected to each other to achieve; the color surface composed of color dots and color lines drawn by a brush with a microporous structure pen tip is composed of a certain number of color dots and color lines, so each color change in the color surface depends on the density of the arrangement of each color dot and each color line, the degree of superposition, the degree of exposure of the color of the basic color layer, and the visual mixing to achieve it, and the organizational relationship of the color lines to form the color surface is a cross relationship or a non-cross relationship. The above is the difference between the color surface painted by a flat-bristle brush and the color surface composed of color dots and color lines drawn by a brush with a microporous structure pen tip in expressing the color, shape and structure of the image on the picture. The flat-bristle brush has a wide head and is a soft brush head. It has good brushing performance and is suitable for expressing the color, shape and structure of the image on the picture surface with the painted color surface; the microporous structure brush has a thin head and is a hard brush head. It has good painting performance and is suitable for expressing the color, shape and structure of the image on the picture surface with the painted color points, color lines, and color surfaces composed of color points and color surfaces composed of color lines. The specific steps of this method are described below: the first step is to select a flat-bristle brush of different widths according to the size of the picture and dip it in oil paint to apply a layer of basic color of the image on the picture, that is, to spread a base color and use the color surface painted by the flat-bristle brush to express the color, shape and structure of the image on the picture surface to form a basic color layer. The second step is to express the color, shape and structure of the image on the picture surface with the color points, color lines, and color surfaces composed of color points and color surfaces composed of color lines drawn by the microporous structure brush on the basic color layer in the first step. Since the prior art only uses one color surface painted by a bristle brush to express the color, shape and structure of the image on the picture, the expression means is single, while the present invention uses three color surfaces, namely, the color surface painted by a flat-headed bristle brush, the color surface composed of color dots drawn by a microporous structure pen brush, and the color surface composed of color lines, to express the color, shape and structure of the image on the picture. The expression means of the present invention using color surfaces to express the color, shape and structure of the image on the picture are richer than the expression means of color surfaces in the prior art.Since the prior art uses a pointed bristle brush to paint the color surface to express the fine parts of the color, shape and structure of the image on the picture, the tip of the pointed bristle brush is a soft tip, and the shape of the tip is uncertain. The brush needs to be held in mid-air, and the area of ​​contact between the tip and the picture needs to be carefully controlled to grasp the shape of the color surface drawn by the tip when painting, otherwise the size and shape of the drawn color surface will be unsatisfactory, and the speed at which the tip of the pointed bristle brush moves on the picture is limited. Therefore, the pointed bristle brush is very slow when expressing the fine parts of the color, shape and structure of the image on the picture; the tip of the brush with a microporous structure tip is a hard tip, and the shape of the tip is determined. The tip can be applied to the picture to draw color dots and color lines, and the brush is easy to control. It can conveniently and quickly draw color dots and color lines to form a color surface to express the fine parts of the color, shape and structure of the image on the picture, which is more convenient to operate and faster than the method of using a pointed bristle brush in the prior art to express the fine parts of the color, shape and structure of the image on the picture with a color surface. Soft pens such as bristle brushes write slowly, while hard pens such as microporous nib brushes write quickly. This view has been confirmed by social writing practices. The evidence is that the most important writing tools in today's society are hard nib pens such as microporous nib brushes that write quickly and fluently, such as fountain pens, ballpoint pens, markers, etc., rather than soft nib pens such as bristle brushes that write slowly and unfluently, such as writing brushes. Writing and painting have a lot in common in the use of such stationery. Therefore, the microporous nib brush uses a color surface composed of color dots and lines to express the fine parts of the color, shape and structure of the image on the picture faster than the color surface painted with a pointed bristle brush. Since the tip of a pointed bristle paintbrush is a collection of many bristles, only when all the bristles of the tip are gathered together can the desired color be accurately painted. The painting process is the process of destroying the gathered state of the bristles of the tip of the pointed bristle paintbrush, so it takes time to restore the bristles of the tip of the brush to the gathered state; the tip of a paintbrush with a microporous structure tip is a whole with a fixed shape, and it does not take time to adjust the state of the tip. Therefore, the painting speed of using a paintbrush with a microporous structure tip to express the color, shape and fine structure of the image on the picture is faster than that of a pointed bristle paintbrush.Since the tip of a pointed bristle paintbrush is a soft tip with an uncertain shape, the method for using a pointed bristle paintbrush to use color planes to express the fine parts of the color, shape and structure of the image on the picture is to paint different color planes on the picture. To achieve a color plane with light and dark color changes in a certain part of a specific image, it is necessary to blend several colors of different shades in this color plane and paint them on the picture in a transitional and connected manner. To achieve such a color plane with a microporous structure tip paintbrush, it is only necessary to blend one color. Such a color plane can be achieved by visually mixing the three factors of the color points and color lines that make up the color plane, the density relationship of the arrangement, the degree of overlap and the basic color layer exposed to different degrees. Therefore, the speed at which the color plane drawn by the method of the present invention expresses the fine parts of the color, shape and structure of the picture image is faster than the speed at which the color plane drawn by the prior art expresses the fine parts of the color, shape and structure of the picture image. Since the dark parts with relatively large areas and gradual color changes in the images of pen drawings are represented by color surfaces composed of lines drawn by the pen with a width of about 1 mm, it takes a long time to complete. The larger the area, the longer the time taken, so the drawing speed is very slow. The present invention uses a flat-bristle brush of a size corresponding to the image to be depicted to paint this type of color surface. If the area of ​​the color surface is large, a wide flat-bristle brush is used. Therefore, this method is faster than the pen drawing speed of the prior art in drawing such parts of the image. Since the drawing tool of pen drawing is a pen, the pen tip belongs to a hard pen tip, which has a fixed shape and a fine tip, and is good at using color dots, color lines, and color surfaces composed of color dots and color surfaces composed of color lines to express the fine parts of the color, shape and structure of the picture image; the pen tip of the microporous structure pen tip paintbrush also belongs to a hard pen tip, which has a fixed shape and a fine tip, and is also good at using color dots, color lines, and color surfaces composed of color dots and color surfaces composed of color lines to express the fine parts of the color, shape and structure of the picture image, so this method can draw oil paintings as fine as pen drawings. In summary, the present invention can draw oil paintings as fine as pen drawings, and the speed of painting is faster than the existing methods of drawing oil paintings and pen drawings, and the means of expression are rich. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0007] Figure 1 It is a schematic diagram of a paintbrush with a microporous structure of the present invention.

[0008] In the picture, 1. pen tip, 2. micropores, 3. oil paint, 4. pen holder. DETAILED DESCRIPTION

[0009] Implementation method 1. Insert the tail end of a fiber microporous structure pen tip with a tail end diameter of 3 mm, a tip diameter of 1.0 mm, and a length of 20 mm into the pen tip plug hole with a diameter of 2.9 mm and a depth of 7 mm of a wooden pen holder with a diameter of 8 mm and a length of 200 mm, and connect the fiber microporous structure pen tip with the pen holder to make a microporous structure pen tip brush. Use a 10 mm wide flat bristle brush to dip the required oil paint and mix it with linseed oil on a palette to make it have good fluidity and permeability, then apply the blended liquid oil paint to the pen tip of the microporous structure pen tip brush, wait for the liquid oil paint to penetrate into the inside of the pen tip through the micropores open to the outside on the pen tip, and then penetrate from the inside to the tip of the pen tip, and then it can be used to draw oil paintings. The oil paint remaining on the pen tip can be washed off with turpentine.

[0010] Implementation method 2. Take the painting of a young female figure sitting indoors with a size of 500 mm in width and 800 mm in height as an example: the first step is to use a flat-bristle brush to paint the color, shape, and structure of the image on the picture. Use a 15 mm wide flat-bristle brush to paint the background color of the figure. Use a 10 mm wide flat-bristle brush to paint the color of the figure's clothes, hair, hands, and face. Use a 5 mm wide flat-bristle brush to paint the figure's earrings until the entire picture is filled with color. Use a 6 mm wide flat-bristle brush to paint the figure's hair, showing the shape of each thick strand of hair and the structural relationship between them. Use a 3 mm wide flat-bristle brush to express the basic shape of earrings and necklaces. Then use a 6 mm wide flat-bristle brush to paint the face, showing the basic structure of the face and facial features. Use an 8 mm wide flat-bristle brush to paint the large folds and large floral decorations on the figure's clothing. After using a flat-bristle brush to paint the surface, the basic shapes of the characters in the painting, the large folds in the clothes and the large floral decorations, and the basic outlines of the earrings and necklaces are completed, a basic color layer is formed. In the second step, on top of the basic color layer, use a microporous structure pen brush to draw color dots, color lines, and color surfaces composed of color dots and color surfaces composed of color lines to depict the fine parts of the color, shape, and structure of the image on the picture. First, use a microporous structure pen brush with a diameter of 0.8 mm at the tip of the pen to depict the facial features of the character, and use dark lines in the same direction as the eyelids to draw the shadow of the upper eyelid cast on the eyeball. The lines in dark areas are dense and even overlapping, and the lines in light areas are sparse. If the color of the basic color layer is dark, mix some slightly lighter colors and draw in the same direction, and then use short lines oblique to the shadow to draw out the deep and dense, and the sparse color surface to create a gradient effect of different shades. You can also draw light lines from dense to sparse in the areas where the color gradually becomes lighter to create a slightly lighter gradient color surface to show the color change of the shadow under the upper eyelid. Use short lines to draw the deep color changes in the pupil, mix some gray and white colors and apply them to a clean pen tip, and dot the highlights of the pupil. Use force and repeat the dots in the bright areas, and dot the dark areas lightly and sparsely or dot slightly darker gray dots. Next, use a microporous structure brush with a diameter of 1.0 mm at the tip of the pen tip to draw the thin strands of hair. First, use a single color line to draw the outline of the dark part of the hair, and then use short color lines arranged diagonally to draw the dark part of the hair. Mix a bright gray color and apply it to a clean pen tip, and draw the highlights of the hair along the direction of the hair. Use horizontal, sparsely arranged short color lines in the transition between light and dark colors. If the middle of the short color line is brighter than the colors on both sides, use shorter white color lines to draw this part. Use a microporous brush with a diameter of 0.7 mm at the tip of the brush to draw the end of a single hair. Use dark gray dots to arrange the dots in a way that becomes sparser and smaller as they get closer to the end, to create the effect that the end of the hair gradually becomes empty and disappears.When depicting the character's earrings, use a flat-bristle brush to mix a dark brown color, apply it to the tip of the microporous structure brush, then use a single colored line to draw the dark side of the earring, and then use horizontally arranged short colored lines of different densities and different superposition relationships to create a gradient strip color surface to show the ring-shaped structure characteristics of the earring. On the basis of using a bristle brush to depict and have basic color characteristics and basic structural characteristics, the method of using a microporous structure brush with a diameter of 1.0 mm at the tip of the pen to draw the fine parts of the character's hand is to use the color plane composed of arranged color lines to express the dark side of the backlight of the finger, and use the color changes formed by the density of the color line arrangement, the degree of color line overlap and the degree of exposure of the basic color layer to express the skin color and structural changes of the finger. Use a single color line with a warm dark gray color to express the dark side of the folds of the back of the hand and the knuckles, and use the same color and gradually sparse color points to express the structural state of the folds of the joints gradually flattening. Use the horizontal arrangement of light and bright skin color short color lines to express the light-receiving surface of the folds, and use color points of different brightness and density to express the highlights. When drawing the floral decorations on the clothes, use dark red color lines to draw the linear pattern of the floral decorations, and use dotted lines composed of color points to express the weak color. The light red in the middle of the linear pattern is expressed by the intensity of the stroke, the degree of coverage of the basic color layer and the color changes formed by the density between the color points.

[0011] Implementation method 3. Take the painting of a landscape oil painting with a width of 1200 mm and a height of 1000 mm as an example: the first step is to use the color surface painted by the flat-headed bristle brush to express the color, shape, and structure of the image on the picture, use a flat-headed bristle brush with a width of 30 mm to paint the large area of ​​the sky with a slightly changing blue and the color and structure of the white clouds with soft color changes, use a 25 mm flat-headed bristle brush to paint the basic gray-brown color of the earth, and use a 15 mm flat-headed bristle brush to express the color, shape, and structure of the stones and flowers on the ground. Use a 20 mm flat-headed bristle brush to dip light green to express the light-receiving surface of the tree crown, dip green to express the middle color of the tree crown, and dip dark green to express the dark side of the tree crown, and express the shape and structural characteristics of each tree crown, so as to complete the drawing of the basic color layer. The second step is to use the microporous structure pen brush to draw the color points, color lines, and color surfaces composed of color points and color surfaces composed of color lines on the basic color layer to depict the fine parts of the color, shape, and structure of the image on the picture. Use a 10mm wide flat-bristle brush to mix a gray-brown color and apply it to the tip of a microporous brush with a diameter of 0.8mm. Use drawn colored lines to represent the beak of a bird flying in the sky, and use a colored surface arranged with colored lines to represent the wings, abdomen and tail of the bird. The colored lines can be arranged in parallel or cross-arranged as needed. Use a gradient colored surface composed of gradually sparse colored dots approaching the edges to represent the effect of the emptiness of the edges of the bird's wings and tail. Use warm gray colored lines to represent tree branches with the sky as the background, and use gradually sparse colored dots approaching the tips to represent the effect of the branches gradually becoming empty near the tips. The color plane composed of colored lines drawn by a brush with a microporous structure with a diameter of 1.0 mm at the tip of the pen is used to express the concave and convex structure on each surface of the stone, the cracks of the stone are expressed by colored lines, the holes on the stone are expressed by colored dots and colored planes composed of colored dots, small holes are expressed by colored dots, and large holes are expressed by color planes, the light-receiving parts of the holes are expressed by a color plane composed of light gray and sparsely arranged colored dots, and the backlit parts of the holes are expressed by a color plane composed of dark gray or black gray, densely arranged and even overlapping colored dots. Use dark green lines in the same direction as the branches to express the backlit side of the thin branches of flowers, use light green lines to express the illuminated side of the thin branches, use a color plane composed of color lines oblique to the branches to express the middle color and dark side of the thick branches, and on the basis of this color plane, draw color lines of different densities in the same direction as the thick branches in a superimposed and covering manner to express the transition of the branches from the middle color to the dark color. The bright side color of the branches is expressed by the color plane formed by drawing short light lines horizontally to the branches. Use color lines to draw the outlines of flowers and leaves, and use a color plane composed of color lines of different densities, parallel arrangements, cross arrangements, or different degrees of overlap to express the shadow of each petal and leaf and the shape of the petals and leaves themselves. Use a color plane composed of color dots and color dots of different densities and overlapping relationships to express the stamens, and use color lines of different shades to express the petioles and veins of the leaves.
