Tinplate does not have the ability to absorb ink, which means that the drying of ink depends entirely on external conditions, such as drying temperature and curing time. If the drying speed is too slow, the printed product is prone to adhesion; if it is too fast, the ink layer may be unstable, affecting the printing quality.

The safety of printing tinplate sheets first depends on the raw materials selected. Manufacturers must select high-quality raw materials that meet international standards to ensure the basic quality of each piece of tinplate.
