The profit of outdoor advertising inkjet printing and photographing used to be quite high, which can be said to be some huge profits. But now, due to the increase of employees in the same industry, the price war and the constant transparency of consumables prices, there is not much profit in this industry. If you want to make money, you can still make money only by providing good service and ensuring the increasing number of customers. One more thing, if you can develop your own advertising media, you can still make a lot of money, such as some outdoor advertisements, and you can also save some costs by designing your own inkjet.
