Analysis: Requirements for Flexographic Printing on Packaging Design

Packaging design refers to the overall design and planning of a certain packaged product. It generally refers to the overall design of the screen composed of packaging shapes, colors, words, trademarks, and patterns. Packaging Tongying inch is the basis for platemaking and printing. A well-designed design may not produce satisfactory results after plate making. Some seemingly unsatisfactory design drafts may meet the requirements of plate making and printing, and sometimes May show better results. Therefore, in the packaging design, in determining the layout of the pattern, the selection of colors, and the arrangement of the characters, in addition to considering the nature of the goods, aesthetics, and artistic effects, the actual effect after the plate printing needs to be considered.

1. In the use of color

(1) The structure of the pattern should be clear and concise, the subject should be prominent, and the colors should be vivid. To avoid the complicated composition and the excessively small blocks and excessively overprint lines, it is necessary to avoid difficulties in the accuracy of the plate printing. Some manuscripts with good artistic effect on the larger pages have no good effect when they are reduced to small screens, because the outlines and levels of the manuscript details cannot be reflected in the small version.

(2) Use spot colors to make up for the lack of four-color printing. The color of packaging design is a difficult and difficult to grasp, and it is prone to tedious problems. In addition, it is also prone to dull shades, straightforward tilings, and inconspicuous keynotes, making packaging prints unattractive. To overcome these shortcomings, designers are required to familiarize themselves with the color principle of plate printing, to accurately grasp the color harmony, and to produce rich-color print images with the minimum color of plate-making.

(3) A large area of ​​the field cannot be placed on the same plate with fine prints, dots, and other details. If this situation is inevitable (for example, printing

The number of machine groups is limited, and even if it is the same color, it should be divided into two editions. It is also necessary to properly consider the local pallets. Because of the cable version

The ink layer is thin, high-line number of anilox roller is used to transfer ink to ensure that the dot printing is clear; the ink layer in the field version is thick, and the ink is transmitted through the low-line anilox roller.

High color saturation.

2. At the level of use

(1) The level of highlights and shadows should be flat (ie, the level of change should be less), high light at about 8% to 10%

(2) Gradient mesh try not to use a gradient effect of 0 to 100%, so as to avoid the net at dark spots and the dark tone to the ground.

3. In line and word processing

(1) It is not appropriate to use fine and small text, wide-width note ≥ 0.17, narrow-width note ≥ 0.08, and the width of independent lines ≥ 0.2.

It is not appropriate to use the Chinese character of the Song type, because when the pressure of the printing changes, the graphic text will show a large amount of deformation, making the positive image text thicker and the negative image text thinning or sticking to death.

(2) The Yinxian should not be placed on the screen.

Avoid designing transverse rectangular solid bars along the axis of the print cylinder, otherwise it will cause machine vibration. It is better to design oblique lines, curves, wave lines and other irregular curves, because it can make the printing roller evenly in the printing process. It will not cause the printing roller to jump violently, so that the large degree of separation will improve the printing quality.

(3) Layout avoids the design of large circular patterns, because when the plate is elastically stretched or elastically compressed, the regular geometric shapes become irregular and the circles become elliptical, which affects the printing quality.
