What are the Key Features of Flexographic Printing Machines?
The steady development of flexographic printing machines is not only due to technological breakthroughs in plates and inks, but also largely attributed to the inherent features of the machines themselves, which are a major factor in attracting users.
The key features of flexographic printing machines include the following:
-
Simple Structure and Cost-Effective: The machine structure is simple, making it easy to operate, maintain, and repair. Flexographic presses with equivalent functionality cost only about 30% to 50% of offset or gravure presses.
-
Wide Substrate Adaptability: They offer strong adaptability to various printing materials. Satisfactory printing results can be achieved on substrates ranging from plastic films as thin as 0.22 mm to corrugated cardboard as thick as 10 mm.
-
Low Printing Pressure: The printing pressure is low (approximately 19.6–39.2 N/cm²), which is particularly suitable for printing on substrates like corrugated paper that cannot withstand excessive pressure.
-
Low Production Costs: Printing costs are low primarily due to the affordable machine price, lower plate-making costs, and a low waste paper rate during the printing process. Overall, production costs are 30% to 50% cheaper than gravure printing.
-
High Print Quality: By utilizing an anilox roller with a short ink path system, the ink delivery structure is simplified, allowing for precise quantitative control of ink film thickness. Technological breakthroughs in high-performance photopolymer plates have significantly improved plate resolution and dot reproduction (achieving 1%–95% dot range). Flexographic printing can produce color halftone prints at 300 lines per inch (lpi), delivering print quality comparable to offset and gravure printing.
