Good evening. There is no way to calculate this. It depends on how big your model is and what ink you use (UV, weak solvent, common water-based pigments, etc. ). If it is a self-modified tablet computer, the cost can be ignored. If it is purchased, it usually includes the depreciation cost of the equipment. Only the ink consumption for printing and painting is less than 65,438+00% of the total cost. For example, spray a brushed aluminum wedding photo of 1 square, and even 50 ml of ink is not used in the whole format. If it is coated with water-based ink, it is only a few dollars, and it is not expensive to charge 80 yuan. Of course, everyone has a different calculation method, if you want to calculate the rent.
