In recent years, with the continuous development of the printing process, the equipment in the hands of printers has been continuously updated, but in the process of realizing the map elements from offset to paper (or silk), the printers are exposed to the harmful gases emitted by the ink every day to the body Health has caused some damage.
[Symptoms and causes] In early September, in order to ensure that the map printing task of a certain area was completed on time, the officers and soldiers of the map printing team of a surveying and mapping brigade of the Guangzhou Military Region struggled through the production line overnight.
