Is the printing house poisonous?

Printing houses are toxic, and most of the toxins are hidden in ink, which contains organic solvents such as ethanol, isopropanol, toluene and xylene. Organic solvents are volatile, especially for printed matter with large inking area and thick ink layer, there are many residual solvents. Toxic substances released during use will pollute the air and endanger human health.

Printing is a technology that transfers ink to the surface of paper, fabric, leather and other materials through the processes of plate making, ink application and pressure, and copies the contents of the manuscript in batches. There are many forms of printing: traditional offset printing, screen printing, digital printing and so on. Stencil printing, relief printing, gravure printing and lithography are called the four modern printing technologies. The printing factory is a comprehensive organization integrating design, proofing, plate making, printing, binding, packaging and transportation. Of course, the most important thing is that a printing factory must have printing equipment to be called a printing factory, and the printing machine is the most important. Printing machines are available in monochrome and bicolor, as well as in four and eight colors. According to specifications, it can be divided into eight starting, four starting, half starting and full starting. Some simple printing can also be done by screen printing, and printing can be completed with only one screen, but the effect is not as good as that of large-scale printing.
