The unique material of tinplate determines that it must be highly compatible with ink to ensure the printing quality and durability of the pattern. The surface of tinplate is usually smooth and has a certain hardness, which makes it impossible for ordinary ink to adhere directly to its surface, and thus puts higher requirements on the performance of ink.

Printing tinplate wastewater contains a large amount of ink particles and chemicals, which can be treated by physical and chemical methods such as coagulation, sedimentation and filtration to remove harmful substances.

some leading printing tinplate companies have introduced digital inkjet printing technology, which can achieve high-precision pattern printing on the tinplate surface and can be personalized to meet the needs of different customers.
