The advantage of laser engraving ceramic anilox roller and flexo printing

The advent of laser-engraved ceramic anilox roller is the main factor that contributes to the breakthrough of innovation in Flexo printing technology. The mesh shape is generally divided into the following categories: Hexagon 60/30, Diamond 45, and Slash type ( Tri-helical) 1-89.

Advantages of Laser Engraving Ceramic Mesh Drum Long service life: wear-resistant, mesh volume is always fresh, and the printing color is uniformly maintained.

Highly resistant to damage: The clay is hard and can withstand 375,000 pounds per square inch, which is about fifteen times that of a typical embossed chromed roller.

The volume of ink is extremely large: Since the mesh has a circular shape, the ink capacity is more than the embossed mesh of the sharp bottom shape, and both the dot printing and the full-bottom printing can be taken into account at the same time.

Error-free network effect: Moiré mainly refers to the phenomenon in which the mesh and the printing dot are arranged with each other to form a staggered state and cause ink inhomogeneity. Laser-engraved meshes, because of their arrangement with the printing screens, are in a random state, so there is no regular staggering of geometric patterns.

Excellent corrosion resistance: The ceramic layer with a corrosion resistance is directly covered on the metal substrate, which can effectively improve the corrosion resistance of the roller.

Configuration diversification: Because of the excellent pressure resistance of the ceramic surface, it can withstand the scraping and wiping of the scraper, and can be used with a scraper or a double-drum wiping system.

Does not hurt the knife damage version: circular mesh points do not have a sharp corner edge, no damage to the damage of the knife, can significantly extend the service life of the blade and printing plate.

Replaceable cable: U-shaped laser engraved hole, compared with the mechanical embossed V-shaped shape, with a larger volume, in order to get the same amount of ink, if appropriate with a higher number of U-shaped mesh, you can get it right.

Network cable meticulous: With laser engraving, 1000 lines can be easily carved, far exceeding the limit of mechanical embossing 400 lines, and the improvement of the effect of color dot printing can be described as endless.

Improve ink release: circular mesh shape, easy to release ink, help the transfer of ink.

The comprehensive precision is good: the laser engraving drum is a laser gun, which indirectly burns heat energy on the surface of the ceramic layer to form a mesh, which is different from the direct mechanical contact pattern of the general mechanical embossing and does not affect the original accuracy of the roller. And there is no negative effect on the TIR.

Laser engraved ceramic drum use essentials In the double-dyeing ink system, the mesh drum is the rubber roller running in the ink tank and between the plate cylinder. When the printing speed increases, the amount of ink in each roller gap also increases. Not only does it overflow the mesh, but it also spreads to the surface of the roller. In addition to the stain, it also derives the printing network and the phenomenon of ink stains appears. Especially when the printer is worn out, or when the ink viscosity mutates, it becomes more prominent. In short, with the speed of printing, the amount of ink tends to increase or decrease.

Solution: With a doctor blade wipe system, as a solution. When the device is installed, the blade fixing sleeve must be firm and inflexible to prevent the tool from leaning and the accuracy between the components must be within the allowable error so that the blade and the surface of the cylinder can be evenly touched and the ink can be easily scraped off. .

Considerations for printing conditions It is recommended to use a doctor blade to wipe the ink to obtain a uniform and stable ink control effect.
̇ 60° Honeycomb laser sculpted mesh, hole wall smooth, can extend the service life of the blade.
The mesh wall of the larvae is thin, and a well-balanced printing ink layer can be obtained.
̇ High number of meshes can improve the accuracy of printing, and can suppress the phenomenon of printing dots.
̇ Low ink mesh (high number of lines), with proper ink (high concentration), can be obtained in the same printing color as the ink layer becomes thinner.
̇ If you want to achieve stable and beautiful printing results, be sure to use elastic pad thin printing.
̇ Be sure to follow the test results so that the conditions complement each other to achieve the best results.
