1. Impact of squeegee

The hardness of the doctor blade is lower than the hardness of the chrome layer on the surface of the printing plate. If the hardness of the squeegee is too high, it will accelerate the wear of the printing plate and produce scratches: if the squeegee is of poor quality, it will wear out in a short period of time, resulting in the ink on the plate surface not being cleaned, and a knife line appears At this time, frequent tool adjustments and tool changes are required.

When the squeegee blade is damaged and there is a gap, there will be a regular line of left and right movement on the printed matter, which is easier to identify. If the gap on the doctor blade is relatively fine, it can be polished with oilstone or fine sandpaper until smooth and smooth. If the gap is large, a new doctor blade needs to be replaced. When replacing a new knife, the accumulated ink on the pressure blade and the knife groove must be completely cleaned to avoid affecting the flatness of the installation of the doctor blade, and the length of the blade exposed to the pressure blade should be the same, about 5mm. In the printing process, some squeegee blades need to run in with the printing plate for a long time to achieve a good squeegee effect. At this time, metallographic sandpaper can be used to smooth the edge of the squeegee blade, so that the squeegee blade can reach Better ink scraping effect, and is conducive to the improvement of production efficiency.

Secondly, the poor flatness of the installation of the doctor blade will also cause the knife line of the printed matter. Therefore, when installing the doctor blade, make sure that the flatness is good, so that the doctor blade is evenly stressed. In addition, the pressure and angle of the squeegee have a great influence on the print line. During printing, the angle and pressure of the squeegee blade should be adjusted according to the degree of squeegee on the layout and the inking condition of the printed matter, so as to achieve a good squeegee effect, thereby reducing the occurrence of faults in the printed article.

It is more suitable to choose self-grinding squeegee with tight material and moderate hardness. Pay attention to the angle and pressure of the doctor blade during operation, so that it can not only wipe the ink clean, but also reduce the wear of the doctor blade on the printing plate and the wear of the doctor blade itself, thereby improving the printing plate and doctor blade The life of the tool reduces the generation of cutting lines.

2. Effect of solvent

In the printing process, solvents are often used to adjust the viscosity and dryness of the ink. In actual operation, it should be as soluble as possible. Solvents that evaporate quickly, such as ethyl acetate and isopropyl alcohol. Different types of inks should use different types of solvents. If the solvent is not used properly, the ink will not dissolve sufficiently and stick together. Once it sticks to the doctor blade, it will form a knife line.

This kind of knife line is usually a dark line, sometimes there is no. It is more common to print solid color blocks with gold ink. Since gold ink is formulated with gold powder, gold oil and solvent, the metal particles are relatively heavy and easy to precipitate. If the solvent used has poor solubility, and the stirring is not Fully, metal particles will accumulate due to uneven distribution. If it stays at the blade of the squeegee, a thick dark line will form. The characteristic of this dark line is that it disappears automatically after a certain period of time, and then forms again, which seriously affects the quality of printing. This type of knife line is difficult to eliminate in printing. It is necessary to start from the roots and work from the pre-printing preparation work. Use appropriate solvents when mixing the ink, stir it to fully dissolve, and maintain a good ink circulation during printing.

Bronze Sculpture

Chinese people are very fond of sculpture, sculpture and other cultural arts. This art is relatively inherited. It has been in our country for a long time, and it has been up to now. Carving can not only carve out beautiful patterns, but also has the effect of cultivating one's character, which is a very good interest. In the sculpture industry, although the price of copper sculpture is relatively expensive, compared with sculptures made of other materials, the overall performance of copper sculpture is particularly excellent. It's very strong, safe and reliable. It is found that bronze sculptures are used very frequently in urban landscapes and are loved by citizens of all countries around the world. Bronze is hard and chemically stable. In history, bronze equipment has been used to make ritual instruments since the Shang and Zhou Dynasties, which are still well preserved. From the appearance, the appearance of the bronze sculpture is very natural and textured, the glaze looks very soft, and the rich copper layer reminds us of our long history and culture. Although copper is not as precious as gold or as shiny as aluminum alloy, its seemingly natural material can show a unique temperament, which is not possessed by other materials. I think the greatest commonality between sculpture and love is the pursuit of an eternal possibility. Sculpture gives its hard material, and love gives its clear soul."
