However, in these two years, each country has strict environmental protection restrictions on import and export products, and the commodity inspection thereof must meet the SGS environmental protection commodity inspection test of the european union, and the license for environmental protection can be obtained to have import and export qualifications. Due to the above-mentioned commercial inspection, the seemingly insignificant micro logo printings may cause immeasurable significant economic losses to the enterprises, and export is restricted to the standard series.

At present, the printing and lettering processing industry in China basically adopts traditional Tianna water, benzene, acid and aromatic hydrocarbon chemical raw materials containing toxic and harmful substances as a diluent, and the diluent is basically composed of toluene, butyl acetate, cyclohexanone, isoamyl acetate and ethylene glycol ethyl ether acetate and belongs to national contraband; the long-time contact of human body can cause diseases of central nervous system, damage to liver and kidney, and cause acute conjunctivitis, pharyngolaryngitis, bronchopneumonia, pulmonary edema, headache, nausea, emesis, chest distress, palpitation, inappetence, etc. It can be used for treating chapped skin, dermatitis or eczema. Tianna water is inflammable and toxic, and can cause combustion and explosion when meeting open fire and high heat.

Because the diluent belongs to a high-risk material, the disadvantages of personal health and environmental pollution can be caused, and the environmental protection requirements of national and international import and export product packaging labels are not met; more importantly, the manufactured quota export commodity must pass through the European Community imported commodity and materials, and the harmful and toxic substances thereof must meet the export standard only if the SGS environmental protection detection certification is less than the commodity inspection certification of 0.1. Therefore, in recent years, the environmental protection control force is increased in China, and various measures which are promoted by the international environmental protection organization and concern about environmental protection are actively responded to control and promote the environmental protection measures. Specifically, especially the printing standard in the cable manufacturing industry, the printing standard requirements of GB5023, GB12706, GB5013, GB9330 and JB8734 must be met; the complete cable identification printing must have: the name, model, voltage, core number, section and meter code mark of the manufacturer, so the marking and printing of the wire and cable mark are necessary procedures of production and manufacturing enterprises.
