5. Performance technology of commercial bag printing

The design must not only consider the ideological, authenticity and artistry of the advertising performance, but also take into account the characteristics of the printing process. Should pay attention to the following questions:

Take into account the opening number of paper. Unbalanced design drafts cause unnecessary paper waste. Therefore, it is best for designers to have a sheet of paper on hand for reference.

Select the paper type appropriately. For example, color printing business bags can use single-sided coated paper, and the number of grams of paper can be smaller. Can also use the texture of different paper surface selection of cloth paper, egg paper, glossy paper and so on. Many times, commercial bags are used outdoors, so in addition to requiring durable high-quality paper, care must be taken to use high-quality ink that does not fade.

Prepare a plate-making picture, and enlarge or reduce the size of the manuscript by the size of the original. According to the needs of the design, unnecessary content in the picture may be cropped or hollowed out.

The designer should have a printed chromatogram on hand to use when selecting colors. The design color should be solved in red, yellow, blue and black colors as much as possible, and spot colors should be used less to avoid increasing the cost. When designing the background color, avoid large areas of dark color as the background color.

When editing the level of the phototype and the color of the selected phototype, attention should be paid to the fact that the small number of imitated Song words should not be reversed, avoiding the use of italics and small texts, and using black text should not be too small. The words on the light-colored background should not be reversed, and the dark-colored words should not be too dark.

If the surface of the business bag is to be mounted, when designing, it is also recommended to avoid using dark colors for a large area of ​​the background color so as to avoid excessively conspicuous bubbles in the slush molding process and affect the effect.

In short, the design of commercial bag must be a trinity of creative arrangement, production, and printing technology, in order to achieve the perfect work.
