It is reported that there are more than 300 green certification enterprises in the country, accounting for 0.15% of the country, but its output value accounts for about 4.5% of the whole industry. Another 60% of the printing enterprises above designated size use computerized plate-making technology and digital workflow. After adopting this technology, the comprehensive cost of environmental protection for printing enterprises is reduced by about 10%. The statistical data of sampling enterprises show that during the green printing process, The output value per 100 million yuan is about 355,000 kWh, saving about 21.7 tons of paper consumption and about 1 ton of ink. The economic efficiency and energy conservation and consumption reduction level of the printing enterprises have been greatly improved.
