The scraper system is a printing press component that is mainly used to scrape off excess ink on the anilox roller to achieve more stable and uniform ink transfer, thereby presenting better printing results.

The system is mainly composed of scrapers and anilox rollers, among which the scrapers can be divided into sealing scrapers and metering scrapers. The main function of the sealing scraper is to keep the ink in the chamber to prevent ink leakage; while the metering scraper is responsible for scraping off excess ink from the anilox roller, so that the printing press can control the ink thickness consistently.

The accuracy and efficiency of the scraper system are key factors to ensure product quality and production efficiency. The following are some important measures to ensure the accuracy and efficiency of the scraper system:

Precisely adjust the scraper angle and pressure: The angle and pressure of the scraper are key factors affecting the ink scraping effect. By accurately adjusting the angle and pressure of the scraper, the appropriate contact between the scraper and the anilox roller can be ensured, thereby achieving uniform ink transfer.

Select high-quality scraper materials: scrapers of different materials have different hardness and elasticity. Selecting scraper materials suitable for specific printing tasks is crucial to ensure the scraping effect. High-quality materials can provide better wear resistance and stability, thereby ensuring the long-term accuracy and efficiency of the scraper system.

Regular maintenance and cleaning: the scraper system will accumulate ink and impurities during operation. These residues will affect the scraping effect of the scraper. Therefore, regular maintenance and cleaning of the scraper system is an important measure to ensure its accuracy and efficiency.

Use high control systems: modern printing presses are usually equipped with advanced control systems that can accurately adjust and optimize the parameters of the scraper system. These systems can automatically adjust the angle, pressure and speed of the scraper according to actual printing needs, thereby improving the accuracy and efficiency of the scraper system.
