Definitions

• the present invention relates to a printing method, and more particularly to an offset printing method for printing oil painting. Background technique
• the printing types are: letterpress printing, lithography, gravure printing and stencil printing.
• Offset printing also known as offset printing, is a type of lithography. It is a printing method that transfers the graphic on the printing plate to the printing substrate by means of rubber.
• a wide range of printed materials can be used, such as wood, fabric, metal, leather, rougher paper, and the like.
• the offset image is flat and slightly stiff. Especially for the high-quality three-dimensional oil painting with unevenness, it does not show the popularity of oil painting.
• the stencil printing includes a stencil, a stencil, a spray, and a screen printing.
• the principle of stencil printing is: The printing plate (the aperture of the paper plate or other plate is made through the ink). During printing, the ink is transferred to the substrate through the hole of the stencil by a certain pressure (paper, ceramics, etc.) ), forming an image or text.
• the stencil printing is the most convenient stencil printing. It is made on a special stencil paper, made of a stencil graphic version by a typewriter or a stylus, and printed on the stencil printing plate with an ink roller. The desired printing effect can be obtained on the substrate. .
• Screen printing is to stretch silk fabric, synthetic fabric or wire mesh on the frame, and make screen printing by hand-painting or photochemical plate making.
• Modern screen printing technology is to use a photosensitive material to make a screen printing plate by photolithography (to make the screen of the graphic part of the screen printing plate)
• the hole is a through hole, and the mesh hole of the non-graphic part is blocked.
• the ink is transferred to the substrate through the mesh of the graphic portion by the extrusion of the squeegee to form the same graphic as the original.
• the screen printing equipment is simple and easy to operate, and the printing and plate making cylinders are easy and low in cost, and have strong adaptability.
• the advantages of screen printing are: thick ink layer, strong hiding power, and a three-dimensional effect.
• the disadvantage is that the image is not clear and sharp.
• a three-dimensional offset printing method for printing oil painting comprising the following steps:
• the film is printed on the film
• the oil painting obtained has a concave and convex feeling and has a real touch of hand-painted oil painting.
• Figure 1 is a flow chart of the method of the present invention
• FIG. 3 is a schematic view showing a dot formation on a film in the present invention.
• Figure 4 is a schematic view of an internet point of a screen printing substrate
• Figure 5 is a schematic view of a portion of the oil painting
• Figure 6 is a schematic illustration of the side of the oil painting of Figure 5. detailed description
• FIG. 1 it is a block diagram of the product of the present invention.
• the method of the present invention first performs step 101: using computer software to represent the oil painting dots to form an electronic data file.
• AM amplitude modulation dots
• FM frequency modulation dots
• the density of the dot of the AM dot is fixed.
• the color depth is adjusted by adjusting the size of the dot, thus achieving the transition of the tone.
• the invention defines the following characteristics of the network point in the computer software according to the characteristics of each point of the oil painting: the size of the dot, the shape of the dot, the angle of the dot, and the precision of the wire.
• the dot size is defined by the coverage of the dot. Using “ ⁇ " as the unit of measure, for example, a site with 10% coverage is called “one dot” and a site with a coverage of 20% is called “two mesh”.
• the network with a coverage rate of 0% is called “the absolute network”, and the network with a coverage rate of 100% is called the “solid”. as shown in picture 2.
• the recessed portion of the present invention defines a coverage of 10% to 30%, the portion where the unevenness is not defined defines a coverage of 40% to 60%, and the portion where the projection is defined is 70% to 100%.
• the map defined by the dot is embossed.
• the invention divides the content on the oil painting into three levels of tone: bright tone, middle tone, and dark tone.
• the highlighting section sets the dot coverage to 10% ⁇ 30%; the midtone section sets the dot coverage to 40% ⁇ 60%; the darkness section is 70% ⁇ 90%.
• the net and the field are divided separately.
• the shape of the dot is defined in the computer software according to the unevenness of the different positions of the oil painting, and the circular shape, the square shape and the diamond shape are respectively used.
• the points on the oil painting are lines, graphics and some hard-toned images, at 50 Under % coverage, it is defined as a square dot. Its particles are sharper and have a strong ability to perform at levels.
• the point on the oil painting requires that the level performance is not prominent, it is defined as a circular dot. Because the grid is independent between the bright and the middle, only the dark ones are partially connected.
• it is defined as a diamond dot, because it combines the hard tone of the square dot and the soft tone of the circular dot, and the color transition is natural.
• the method of the present invention reasonably defines the angle of the dot according to the above characteristics.
• the size of the dot line determines the fineness of the image.
• the method of the present invention defines the number of dot lines according to the characteristics of the oil painting. For example: 10-120 lines; 150 lines; 175-200 lines; 250-300 lines.
• the difference between the FM network point and the AM network point is:
• the size of the network point of the FM network point is fixed. It is achieved by controlling the density of the network points.
• the invention comprehensively utilizes frequency modulation network points and amplitude modulation network points.
• the dot portion is defined to be sparse in the bright portion, and the dot portion is densely defined in the dark portion.
• the present invention expresses the oil painting in the electronic data file, and comprehensively uses the dot size, the dot shape, the dot angle, and the dot line number to make the convex and concave effects.
• step 102 the film is output according to the electronic data file. Because of the definition of the halftone dots in the above step 101, the film has a high portion and a low portion, and has a concave-convex feeling.
• Step 103 Film repairing the painting, according to the needs of the original painting of the oil painting, the convex and concave parts can be modified to further strengthen the strength.
• Step 104 coating the photosensitive liquid.
• the photosensitive liquid is applied to the film prepared in step 103, and the form of the film coated with the photosensitive liquid is shown in Fig. 3.
• 10 points is an example of a dot with a coverage rate of 10%.
• 20 points is an example with a coverage rate of 20%. Therefore, 20 points is bigger than 10 points, and the film layer is thicker.
• 30 points and 40 points are examples of coverage rates of 30% and 40%, respectively.
• the coated photographic solution can be applied once or twice. When the unevenness of the oil painting is relatively large, the number of times the photosensitive liquid is applied is increased.
• Step 105 the film will be printed.
• Step 106 screen printing, the bottom of the picture printed on the substrate will have a convex, concave texture, but there is no oil painting pattern.
• 310 points are examples of outlets below 30%
• 320 points are below 50%
• 330 points are below 70%
• 340 points are performance of 100% coverage points.
• the ink is less under the solid and forms a bottom layer
• the 330-point coverage is 70% or less, and the ink is much underneath to form a thick layer.
