The market share of printing rollers in the roller industry and roller enterprises has been decreasing over the years. In recent times, with the development of the papermaking, textile dyeing and printing, and woodworking machinery industries, especially the growth of the metallurgy sector, it has spurred the development of the roller industry catering to these sectors. Particularly in the metallurgy industry, the main application of rollers is concentrated in cold rolling production lines, continuous rolling annealing lines, galvanizing lines, color coated steel plate production lines, and various plate precision processing lines, with a large demand for rollers. Due to the interconnectedness of the roller industry, the majority of domestic printing roller manufacturers have expanded into multiple roller applications, leading to a decreasing proportion of printing rollers within the overall roller industry and enterprises, which in turn has somewhat restricted the growth of the printing roller sector.
