Packaging box printing need to pay attention to what details

What details should be paid attention to in the design process of packaging boxes (bird’s nest boxes, sea cucumber boxes, antler boxes, etc.)? What are the common processes in post-printing? What should be paid special attention to? This is not only a question that designers need to ask all the time, but also for printers to be clear about the details of the process.
The main focus of the first phase is on material issues, packaging boxes in the process of designing the main attention to the paper thickness! Because the material is different, in the later die-cutting and gluing box will consider the problem of receiving bit. If the box is card color does not consider this problem, there will be a phenomenon that does not match the design.
There are very few post-production processes: mainly laminating (tile paper or double-layer paper), laminating, UV, die-cutting, laminating, hot stamping (silver) gluing, etc. In addition to this, there is the printing process of the team source file processing above the details of the problem, RGB map is not converted to CMYK consequences: most of the software (FreeHand, Pagemaker, etc.) will not be RGB map color separation, if the RGB map is mistakenly used If you use the RGB map by mistake, the color separation floppy film will either have a map on the black version only, and the other color versions will be empty, or there will be grayscale maps of equal value on the four color versions.
Solution: If you use a scanner that supports direct scanning of CYMK, it is best to scan directly into four-color files; if you can only get RGB, then be sure not to forget to convert RGB to CYMK before output. For TIFF images, you can make a judgment by observing the previsual color of the image in the typesetting or layout software: CYMK TIFF images have a brighter and unnatural previsual color, while RGB images have a more natural color. As for the EPS chart, it is difficult to distinguish from the pre-view, so you can only check them one by one if you are not sure.
