Where to Find Cheap Offset Printing PS Plate
In the printing industry, PS plates (pre-coated photosensitive plates) are the core consumables of lithographic printing, and their performance directly affects the printing quality and cost.
The global PS plate production is highly concentrated, with China and Taiwan in a dominant position. With a complete aluminum processing industry chain, China has become the world's largest PS plate manufacturing base.
Enterprises represented by Hongchang produce high-precision aluminum plate bases through electrolytic grinding, anodizing and other processes. Its original multi-layer sand screen technology (large wave, medium wave, small wave structure) significantly improves the printing plate's printing resistance and anti-fouling ability. So if you want to buy cheap offset printing ps plate, Hongchang is an ideal choice.
From the perspective of the price system, China's PS plates have significant competitiveness in the mid- and low-end markets with their large-scale production and aluminum resource advantages. Taking Hongchang as an example, its 0.10-0.50mm PS plate base uses electrostatic spray matte treatment technology to shorten the platemaking time by two-thirds, and the comprehensive cost is reduced by 15%-20% compared with traditional processes.
In contrast, the PS plates of technologically advanced countries such as Japan and South Korea are generally 30% more expensive than similar products in China due to their high R&D investment.
The quality differences of PS plates are mainly reflected in coating uniformity, chemical resistance and platemaking efficiency. China's leading companies have achieved a coating thickness control accuracy of ±5μm through CTCP (computer-to-plate) technology, and combined with a special straightening process to eliminate cold rolling hard marks, so that the flatness of the printing plate reaches the industry-leading ±0.02mm.
In the high-end market, brands such as Japan's Fujifilm and the United States' Kodak still maintain technical barriers. The thermal PS plates they developed can achieve nano-level dot restoration at 200°C, but the price is 2-3 times that of similar domestic products.
With the transformation of the printing industry to digitalization, the ps plate offset supply market presents two major trends: one is the popularization of environmentally friendly processes, such as solvent-free coating technology to reduce VOC emissions; the other is intelligent production, using AI visual inspection systems to control the scrap rate below 0.3%. Chinese companies are accelerating their layout in overseas markets, with exports accounting for 32% of global trade in 2022 and products covering emerging markets such as Southeast Asia and the Middle East.
