There are two kinds of knife carving, yin engraving and yang engraving, that is, concave line and convex line. Step 1: Draw the pattern and make the plate.
Step 2: Separate the colors and ink them on the plate one by one. Tools are generally rollers.
Step 3: Transfer the image and start the draft.
Gravure plates, in contrast to letterpresses, are engraved with grooves on the flat surface of the plate, and when the ink is rolled on, an image with white lines on a black ground can be printed. The polished metal layout does not absorb ink. The ink of the copperplate engraving can be gently polished with a cloth, but if the layout shows signs of being scratched, the ink will remain there.
The plates of modern intaglio prints are mainly copper and zinc, sometimes iron or steel, and are engraved in the following ways. One of the oldest intaglio engraving methods, using a solid sharp knife, to engrave lines on the surface of a copper plate. The carved lines are bright and sharp.
The layout can be engraved very exquisitely. In the past, banknotes were engraved and printed using this method, and there are still a few stamps engraved in this way.
Intaglio print: (De) Kohler Huich's "Mother's Love" Copper, zinc, steel and other materials that can be corroded by acids are coated with preservatives, and the main components of preservatives are asphalt, rosin and beeswax. Then the image is engraved on it with a needle, and where the needle goes, the preservative is scraped off, revealing the layout, and finally it is immersed in a nitric acid solution, and the exposed part is corroded.
Due to the length of corrosion and the concentration of nitric acid solution, the corroded lines have different depths and thicknesses. Corrosion prints are generally corroded in layers many times, so the color is very rich and the layers are very distinct, which is the most commonly used engraving method for intaglio printmaking.
On top of several copper plates of the same size, several color separation plates are made by flying dust corrosion. According to the plan, the printmaker chooses which color plate to print first, and then which color plate to print. When putting the plate on the machine for printing, first put a thick paper under the copper plate, and glue the paper on the machine, after printing, carefully take out the copper plate, and the pad paper is still left on the machine without moving.
At this time, the marks left by the first impression can be clearly seen on the pad paper, and then the second plate with the lust on it is carefully embedded in this trace. At this time, the edge of the paper drawn for the first time is still pressed under the upper cylinder of the printing press, and only the part of the paper that leaves the cylinder can be removed. Then carefully put down the paper on which the first edition was printed, cover it on the second plate, and shake the roller to accurately overprint the second edition.
The rest of the editions are the same.

The woodcut production is also very simple, first you have to have the board. A good board is very important, basswood board, and then there is the drawing, the expressiveness of the picture. The carved ones are similar. Knives should not be sold too expensive. After all, he is an amateur sculptor. My store number, 80610888

The woodcut printmaking tutorial is as follows:
1: Select the board, mainly the size of the board. In terms of type, Marley woodcut is generally used, of course, its essence is a good plywood, which can be bought in the building materials market. Buy a piece yourself, if you cut it all to A4 size, each piece will cost more than a piece.
2: Polishing, (the easiest step) The surface of the board you just bought is generally a bit coarse. It needs to be sanded with fine sandpaper. Pay attention to the uniform force when grinding. By the way, you can also polish the edges. (This step is prepared for printing).
3: Waxing: (a very important step) is an ordinary candle, of course, you can also buy industrial wax. Spread the board flat, break the wax into small particles, sprinkle it evenly, and iron it evenly with an electric iron. until the wax is half the thickness of the board.
4: Composition, (the most mind-consuming step) can be composed on the draft first, and then printed on the board with carbon paper. If you are drawing a draft directly on the board, switch it to step 3 and draw the draft first and then wax it.
5: Engraving. Because the wooden board itself has fibers in it, only the waxed board will not fluff when carved, and if the knife is good, it is like cutting an apple.
6: Dyeing ink. (The most troublesome step). Start by finding a glass pane, or a larger floor. Pour the printmaking ink a little onto the glass plate, then roll the ink on with a roller (of moderate size) and roll it back and forth on the glass plate repeatedly until the ink is evenly applied on the roller.
Then use a roller to roll back and forth on the board, be sure to paint evenly, if the board is not smooth, you can polish it, otherwise the ink will be uneven. Finally, after the ink is applied, there will be a little ink left in the places that need to be left blank, which can be modified with a carving knife.
7: Printed. (A cautious step) generally uses leather paper, in fact, any paper can be used.
The size is moderate, you can first roll the paper into a bucket, like a mobile phone film, spread the paper evenly on the board, and then use "mushrooms" to roll on it repeatedly. (The wooden handle of its practical carving knife will do, as long as it is smooth and hard). If it is leather paper, it is sufficient until the back of the paper is black and even.
8: Closing the work (the most rewarding step), you can print multiple sheets repeatedly and frame them.

The process of making a woodcut print is as follows:
1. Draw the pattern you want to represent as a concise line drawing or black and white draft. You can draw a drawing directly with a pencil on a blackened board, or you can draw on carbon paper and copy it on the plate.
2. Because the plate is painted with ink, every moment of the knife can clearly show the consequences of engraving. When carving, first use a triangular knife to carve out the surface edge of the wooden board picture, and then use a round knife to gradually carve a bright surface. Pay attention to safety and do not place your left hand in front of the knife when using the knife.
3. Put the ink mixed with turpentine, put a little on the flat-bottomed container with a spoon, such as a plywood, and then roll the oil back and forth to make the ink stick evenly to the oil roller, so as to roll the ink evenly on the plate. Take care to get ink on all protruding parts of the plate. Aiming the paper at the layout to make the paper and the plate stand firmly, you can use clips, etc.
Rub rubbing with wood mushrooms or bottle caps.
5. After the grinding and printing is finished, open it partially to take a look, if there is no printing, it can be partially supplemented with ink, and continue to grind until it is satisfied. Be careful not to move the paper when rolling part of the ink.
Woodcut is a kind of printmaking art that carves a reverse image on a wooden board and then prints it on paper to enjoy. Printmaking is also an important category of Chinese art. Ancient prints mainly refer to woodcuts, but there are also a few copperplate engravings and color omissions.
The unique knife flavor and wood flavor make it have an independent artistic value and status in the history of Chinese culture and art.

Woodcut printmaking is a comprehensive painting art integrating painting, engraving and printing, which uses different carving knives on the wooden board to express the image by means of carving, cutting, shoveling, chiseling, and scratching. Below I will introduce you to the production method of woodblock prints, welcome to read.
Woodcut printmaking method: oblique knife, flat knife, round knife, triangular knife
First of all, teach them how to hold a knife, how to carve straight lines, curves and points, and understand the different artistic effects and charms produced by different knives; How to use black and white expression, consciously carry out black and white processing of woodcut surfaces, and learn some simple expression techniques. At this time, the students were excited and eager to try. Then the teacher asks the students to choose and process according to their interests, type out the sketch on the board, and let them try to practice the feeling and skill of combining woodcut lines on simple figures.
How to make woodcut prints - how to hold a knife:
How to make woodcut prints - knife mark effect:
The slides show a strong black and white woodcut:
1. Comparing the "real legend" and the "black and white draft", students discussed in small groups: What should I pay attention to when conceiving the printmaking sketch? The characteristics of the printmaking process determine that it pursues simplicity, simplicity, flatness and abstraction in form and color.
Black and white woodcuts are printed only in black ink or monochrome ink, with a strong black and white contrast. When designing a black-and-white draft, not only should you exaggerate the subject, but you should also be careful to omit unnecessary details and layers.
2. Black and white woodcuts can express a lot of cute animal content, and students can design according to their favorite animals.
Woodcut Printmaking Practice Stage:
Design and production of black and white woodcuts:
Draft: Draw the animal you want to represent in a brief line drawing or black and white.
You can use a pencil to draw directly on a blackened board, or you can draw on carbon paper and copy it on the plate.
Note that the printed picture is in the opposite direction to the layout, and the layout direction should be considered according to the content of the screen.
Engraving: Because the plate is painted with ink, the engraving effect can be clearly displayed with each engraving.
When carving, the edge lines of the outline on the wooden panel are carved out with a triangular knife, and then alternately combined with a round knife to gradually carve out the bright surface.
Pay attention to safety and do not place your left hand in front of the knife when using the knife.
Inking: Put the ink mixed with turpentine, put a little spoon on the flat-bottomed container such as plywood, and then roll the oil back and forth to make the ink evenly stick to the oil roller, so as to roll the ink evenly on the plate. Take care to coat all the protrusions on the plate with ink.
Grinding: Align the paper to the layout to fix the position between the paper and the plate, etc., using clips, etc.
Rub rubbing with wood mushrooms or bottle caps. Done:

The process of making a trap is as follows:
Use cement to engrave the lettering, as thin as the edge of the copper coin, one for each word, after carving, roast it with fire to make it hard and firm. Prepare an iron plate and spread things like pine resin, wax and paper ash on top.
When you want to print, put an iron royal grill frame on the iron plate, and then row the word seal next to each other, even if it is full, (again) take it to the fire to bake it in Hail Chang, and wait until the pine resin and wax melt slightly, and then use a flat plate to press down on the layout, and the word print is as flat as a whetstone.
If only two or three copies are printed, it is not easy; If you print dozens, hundreds, or even thousands of copies, it will be very fast. (Preferably) always prepare two iron plates, one for printing, one for typesetting at the same time, this one has just finished printing, that one has been arranged, the two are used alternately, and they can be printed in a very short time.
Each character is stamped with several characters, such as "zhi" and "also", and each character has more than 20 stamps so that they can be used when they are repeated in the same edition. When not in use, they are classified according to the rhyme and placed in the wooden compartment. Some rare words are not usually prepared, so they are carved by hand at that time, baked with a grass fire, and can be put into use soon.
The word print is not engraved with wood, because the texture of the wood is dense and uneven, and it will become uneven when it is wet, and it is stuck with pine resin, etc., and it cannot be taken off (when unloading); It is better to use cement to fire, and then bake with fire after printing, so that the pine resin and other substances are melted, and the word print will naturally fall off with a hand, and it will not be stained at all.

Preparation materials: wax, ink, carving knife, wood board, printing paper.
1. Paint the color in advance, so that it is easy to distinguish where it is engraved and where it is not, and the draft is drawn and revised.
2. The round knife engraves a thick line, the triangular knife engraves a thin line, and the flat knife and oblique knife are responsible for a large area.
3. On the engraved print, fully roll the ink evenly.
4. Apply the ink, and observe whether the ink is uniform on the side.
5. Spread the printing paper and compact it fixed.
6. Compaction slowly and vigorously.
7. Finally, pick it up from the woodblock print.

The steps of woodcut printmaking are divided into four steps: selecting the plate, composing, engraving, inking, and printing.
Selection of plates: general 5-layer boards are fine.
Composition: The main thing is that the line drawing is accurate, and the parts that are clearly removed and retained.
Engraving: Use a woodcut knife to get more done with less.
Inking: Roll the ink on the board with a roller dipped in ink, to be even.
Printing: Cover with coated paper, roll vigorously on it with a clean roller, and transfer the ink to coated paper.
