There are significant differences between flexographic printing (flexographic printing) and gravure printing (gravure printing) in terms of plate-making cost, printing effect, environmental protection, printing pressure, and medium adaptability. The following is a specific analysis:
Plate-making cost and cycle
Flexographic printing: The plate-making cost is significantly lower than gravure printing, especially in small-batch printing; the cost advantage is outstanding. Flexographic printing uses flexible resin plates, the plate-making cycle is short, and the process is relatively simple.
Gravure printing: The plate-making cost is high, and engraving or laser plate-making technology is required, and the plate-making cycle is long. The gravure plate is made of metal material, which is durable but has a high initial investment cost.
Printing effect and quality
Flexographic printing: The ink transfer is controlled by the anilox roller, and the printing accuracy can meet general packaging needs, but the detail expression is weaker than gravure printing. The flexographic ink layer is thinner, and the color saturation is moderate, which is suitable for scenes with moderate requirements for printing effects.
Gravure printing: The ink layer is thick, the color is bright, it has a three-dimensional sense, rich layers, and clear lines. Gravure printing can achieve high-precision image and text printing, especially for scenes with strict requirements on printing quality.
Environmental performance
Flexo printing: Water-based inks, UV inks, and other environmentally friendly inks are widely used, with extremely low VOC emissions, meeting food-grade safety standards, and having little impact on the environment.
Gravure printing: Traditional processes use solvent-based inks, which have VOC emission problems and are relatively poor in environmental protection. Although some companies have turned to water-based inks, the overall environmental protection level is still lower than that of flexo printing.
Printing pressure and medium adaptability
Flexo printing: The printing pressure is small, and the risk of damage to the substrate is low. It can print on a variety of materials such as paper, plastic film, aluminum foil, and self-adhesive stickers, especially suitable for flexible media.
Gravure printing: A large pressure is required to transfer the ink from the groove to the substrate, and the thickness and strength of the substrate are required to be high. It is usually used for pressure-resistant materials such as plastic film and paper.
Production efficiency and cost
Flexo printing: The printing speed can reach 400 meters/minute, the equipment investment cost is low, it is suitable for medium and short-run printing, and the comprehensive production cost advantage is obvious.
Gravure printing: The printing speed is fast, but the plate-making cost is high, which is suitable for large-scale printing. In long-run printing, gravure printing can reduce unit costs through economies of scale, but short-run printing has poor economic efficiency.
