Film proofing is a crucial step before the official finished printing
The so-called filming is the process of outputting film sheets with electronic files. For the design of the package, the designed and finished manuscript and die-cutting board files are stored and sent to the production company, and the C, M, Y, K four color separation films and a die-cut version are output through the electronic color separation machine. Single black film. If a spot color is used in the design, each spot color requires a special film output.
Proofing: Making proofs based on film, usually referred to as proofing or proofing. The result of the proofing should be exactly the same as the final finished product. The printing company will check the printing effect according to the proofing and cut the packaging according to the die-cut film.
Check: The designer must carefully proofread the film and proofing results before delivery, which is a crucial step and the last inspection opportunity before the package is officially printed.
Usually the designer needs to check:
1 Whether the proofing result conforms to the design intent, and whether the color effect is consistent with the design;
2 Whether the information content is biased, whether the text is correct, and whether the image accuracy meets the design requirements;
3 Check whether the corners of the four color separation film can be registered from the proofing result, and whether there is a deviation;
4 Die-cutting version does not need proofing, it seems to check the correctness of each part of the cutting line, folding line and marking on the film;
5 Check that the film is clean and clean, make sure there are no holes, scratches, spots and stains.
The reason why you want to check the nuances is to ensure that you can be as sure as possible and reduce the risk before you actually print and produce. Because once the printing is delivered, it is only possible to rework all the errors, resulting in great economic waste.
As a designer, you should not only pay attention to the visual effects of the packaging design, but also strictly control the whole process of packaging design and production in a highly responsible manner. For example, only a dotted line (folding line) mark on the die-cutting board is marked incorrectly, and marking it as a solid line (cutting line) will cause the part that should have been folded to be cut, resulting in a huge loss for the company.
Production samples
After the inspection, it is best to make a packaged finished product to check whether the structure is reasonable and the size is not biased.
Printing production
The modern high-speed development of printing technology has turned ideas that could not be realized into reality, which not only enriched the design methods, but also opened up ideas for designers. Packaging has a wide selection of printing processes. Almost all printing methods can be used on packaging. The key is to choose a printing method that can accurately represent the design concept and be as economical as possible. As a qualified designer, we must accurately grasp the progress of the packaging design and production process. The choice of packaging printing process should be fully considered in the packaging design stage, because "design must be achievable" is the importance of packaging design. in principle. For example: Is it covered? Do you use special processing techniques such as lifting, bronzing, and coating? These must be considered comprehensively.
Once everything is ready to make sure there are no errors, the separation film, die-cut film, and proofing results can be delivered to the printer for printing. Before the production, the design requirements should be clearly communicated with the printing factory. During the production, the designer should supervise and inspect at any time to ensure that the printing results are consistent with the proofing, and the processing technology meets the design requirements.
