Description

Technical Field

[0001] The utility model relates to the technical field of printing and belongs to an ink recovery device for a printing press. Background Art

[0002] Printing inks contain numerous hazardous substances, such as heavy metals and volatile organic compounds. Discharged untreated, these waste inks can cause severe pollution to soil, water, and air. Printing ink production often relies on non-renewable resources, such as petroleum. With the growing global demand for resources, these reserves are dwindling. Recycling and reusing printing inks can effectively reduce the demand for new resources, thereby slowing resource depletion to a certain extent.
