How did the box on the phone case come from, and how could it not be dug out?

This is an extension of the topic of customizing mobile phone cases. Many people think it is very simple to make some patterns on the top of the mobile phone case, just like hand painting. In fact, according to the presentation of the pattern shell, it can be divided into two categories. A flat pattern, a pattern extending to the edge. The plane pattern only needs to be realized on the plane back of the mobile phone case. Plane patterns can be realized by screen printing and digital painting. Screen printing can only choose no more than two colors for overprinting, and the effect is good, but the process needs enough technical experience of the construction personnel, otherwise it is easy to produce waste products, while digital painting is relatively simple and does not need to open the net. The pattern extending to the edge can be seen even on the side of the mobile phone case, which is the extension of the whole pattern on the back. The extension is subdivided into extension to half and extension to cover the whole mobile phone case. If the expansion mode is extended to half, imd process must be adopted, but one problem of this process is that the order quantity of a single model is a bit high, which can not meet the requirements of small batch customization. If only the water transfer printing process can be selected, this process requires a higher order quantity, and the processing price of high-quality water transfer printing process orders is much higher than imd. Many friends like a simple logo, which is an impact monochrome graphic. This is usually done by screen printing, but there are often designs that want to extend this monochrome pattern to the edge, so it is necessary to change from a simple screen printing plane process to a water transfer printing process, which will lead to a kind of incomprehension why such a simple demand will increase the cost of the mobile phone case so much. This is to achieve the effect of increasing the graphic area by 10%-20%, and it needs to obey the cost investment of 100%-200%. Therefore, there needs to be a trade-off between the starting point of design and the cost of timing implementation. Often, if there is enough investment cost, of course, I hope to fully realize my idea, but I can still adopt a lower-cost treatment plan just by testing the water mentality. Digital painting can achieve monochrome and multicolor effects, in fact, the cost is the same, and there will also be mobile phone cases where customers use digital painting to deal with monochrome graphics, that is, the cost of a single product is high, but the minimum order quantity is low. If silk-screen logo is used, the minimum order quantity will be hundreds of single patterns. If the order quantity increases, the processing cost of a single product will be much lower, which is also a trade-off. It depends on the individual's control over inventory management and profit income. I'm a little busy today. Just update this. Thanks for reading.
