Description
Technical Field
The invention relates to an industrial art tool, in particular to a multifunctional scraper for industrial art.
Background
Oil painting scrapers are common painting tools. There are a variety of blade shapes for doctor blades, and the main functions are toning, painting, and cleaning of excess pigment. General oil painting beginners like to draw oil painting with the painting brush, and the scraper is mainly used for clearing up unnecessary pigment, and many higher oil painters who are good for will prefer to directly pick up cream-like pigment with the scraper, smear on the canvas, then evenly open pigment with the blade bottom surface and draw various figures.
The paint with the same thickness can be applied by using a paint scraper, and the painting effect can be greatly different from that of painting. The paint is extruded onto the picture by the knife to produce a series of smooth blocks, often forming ridges or linear edges where each "knife touch" ends. This is a versatile and expressive way of painting, although painting is somewhat difficult to control with a knife initially, as compared to a brush. The drawn 'tool mark' is determined by the direction of the tool, the amount of pigment, the magnitude of the applied pressure and the shape of the tool itself.
Most of the blades of the doctor are made of steel, the price of the common doctor is low, and three to five doctor blades are enough for common doctor painters to finish oil painting works. At present, in the process of drawing oil painting by using a scraper, the amount of cream pigment lifted by the scraper is difficult to grasp and is usually in the process of continuously supplementing or cleaning the pigment; in addition, because the doctor blade is continuously stained with different pigments, the color of the new color is affected because the pigment of the old color on the doctor blade cannot be cleaned up in many cases. Therefore, the multifunctional scraper for industrial art is designed, the pigment amount on the scraper can be adjusted at will, the repeated action of picking up pigment is not needed, and the multifunctional scraper has the functions of the scraper and a painting brush, so that the multifunctional scraper has important significance in reducing the painting cost, improving the efficiency of creating oil painting, improving the internal spirit level of human beings, promoting the development of society towards the direction of being true and beautiful, and the like.
