We know that in general, printing enterprises to implement green printing, from the source of governance is very critical. Therefore, we need to work hard on the purchase of raw materials.
Paper procurement
As the carrier of all printing, paper is the most important link that can not be ignored. In making paper purchases, we need to pay attention to the following points:
l :: Use of paper certified by sustainable forests, paper with more than 30 per cent of waste pulp and paper with more than 50 per cent of non-wood pulp content;
l :: Pulp paper treated with elemental chlorine-free bleaching (elemental chlorine-free or total chlorine-free bleaching);
l :: Primary and secondary school textbooks, teaching aids and workbooks are printed on paper without fluorescent brighteners;
--
Procurement of other printing consumables
In the purchase of other printing consumables, printing enterprises should also pay attention to the following points:
l : Suppliers of raw and auxiliary materials, such as ink, oil, rubber and adhesives, should provide non-added phthalates (plasticizers);
l :The fountain solution does not add methanol, cyclohexanone;
l :The sum of toluene and xylene in ink cleaning agent and blanket cleaning agent should be controlled within the standard range;
l :offset printing ink shall meet HJ/T 370-2007 requirements;

In addition, if the following points can be achieved in procurement, the implementation of green printing for printing enterprises is absolutely bonus points, such as:
l :: Use of alcohol-free fountain solution
l :: Pre-coated materials
