Two or more colors overprinted signage, the edge between the colors should be neat, clear, no gap between the two colors. According to the needs of the product on the surface can be matte treatment, made without light or matte.
Two, performance requirements
Coating adhesion shall not be less than specified.
Color fastness to sunlight should be consistent with the provisions of: indoor use shall not be less than the provisions; outdoor use shall not be less than the provisions. Aluminum anodic oxidation sign, dark color of the front oxide film thickness shall not be less than specified; with light color shall not be less than specified.
Salt spray resistance, shall comply with the provisions. Resistance to heat and humidity performance, shall comply with the provisions. Mold resistance shall comply with the provisions.
Three, the test method
Dimensions of the general gauge and limit gauge test. Flatness of the sign will be placed on a flat plate with a ruler or tape for inspection, the test should not be applied to cause deformation of the sign of the external force. Appearance quality In the illumination of 23 and the visual distance is not less than the conditions, with normal eyesight inspection. Coating adhesion regulations Color fastness to sunlight regulations.
Salt spray resistance regulations. Moisture and heat resistance provisions. Mold and mildew resistance provisions.
Four, inspection specifications
Signs need to be qualified by the manufacturing unit inspection department inspection before leaving the factory. The size and appearance of the signage quality according to the provisions of the normal inspection of the secondary sampling program, the general inspection level, the level of qualified quality, inspection and acceptance. Signage performance quality in accordance with the provisions of the normal
Normal inspection of secondary sampling program, special inspection level, qualified quality level, inspection and acceptance.
The performance quality of the signage is inspected under the following conditions.
Manufacturing process stereotypes; manufacturing process or materials have changed; user requirements; regular one-year assessment.
V. Relevant standards
In order to strengthen the need for quality management, the relevant standards for signage testing are summarized below.
Packaging, storage and transportation of graphic signs

Sign as a professional product, in addition to a certain **** with other industrial products, it also has a very specific personality. The same material, there will be different characteristics, do not rely on the designer's imagination and assumptions. The practicality of the color
Signage equipment, the color of the finish can be based on different needs, the design is colorful. However, simply colorful and beautiful, and
Can not replace its practicality. Color is not only decorative, more functional, the unity of the two, which is called the scientific and practical application of color. Special environment in the customary color, although long used to people, but initially determine its color, still has a sufficient scientific basis, so these popular colors have been used by people. For example, firefighting equipment, including cars, boats, fire extinguishers, buckets and hazardous signals are used red, the reason is that red light in the visible light has the longest wavelength, people's vision is the most sensitive to it, and at the same time, has a strong ability to penetrate and transfer function. For example, the traffic intersection of the red light, is the use of red light wavelength of this feature can be played in rainy and foggy weather color function, in a very long distance can be clearly visible. Similarly, the use of red this note characteristics, not only for decorative purposes, but in some specific occasions is more likely to use the function of color to evoke people's associations. Another example, the use of red decorative firefighting equipment, in order to remind people's attention, easy to find in an emergency; due to customary relations, the red firefighting equipment can give people to the flames and blood associations, thus enabling people to produce a sense of urgency to extinguish the fire inside. By the same token, military equipment is often used in grass-green popular colors, the purpose is to hide the enemy's vision, to protect the target role.
If too much red in the military equipment panels, signs, shells, is bound to be easy to expose the target, not to achieve the effect of concealment. Medical equipment, instruments, color processing, more white or light color decoration, to the medical staff and the sick and wounded to soft, quiet, clean feeling, conducive to the work of medical personnel and patients convalescence. Open-air equipment should take into account the temperature, humidity and sunlight exposure to the color, material, therefore, the design of signage products, should be scientifically selected materials and colors to meet the practicality of the product.
