Definition of color:
Color is the phenomenon of light (e.g., red, orange, peach, green, blue, purple, and yellow) or the visual or perceptual phenomenon that enables one to distinguish objects that are identical in size, shape, or structure.There are three elements of color: light source, object and observer. When any one of them changes, the color also changes with it.There are many factors that influence the color, such as the light source, the background color of the color and the size of the background color, the observer and so on.
Main factors causing color difference of zipper:
1) Special fabrics: Some color samples, such as paper, leather and fleece, reflect different colors to the observer. The dyed color of the chain strips cannot reach the same depth, while the colored samples of transparent fabrics, reflective fabrics and cross fabrics will cause the chain strips to fail to reach the same brightness.
2) Size of the color sample: It is difficult for the dyeing staff to mix and dye according to the color sample with too small area. The area of the customer color sample should be no less than 2cm*2cm.
3) Different fabrics: Different fabrics have different dye-absorbing abilities. Sometimes the raw materials of zipper fabric (such as polyester ribbon) are different from the fabric of the customer color sample, so the dye-absorbing ability is different. Therefore, some colors cannot reach the depth and brightness of the customer color sample during dyeing.
4) Different color setting and methods: If the light source, method and environment are different, the customers will make different judgments on the color.
5) Difference in determination criteria or reference: that is, different color standards or color lights are used, just like different colors reflect different effects to observers under D65 and TL84 lights;Or be like the influence of waterproof film, the color of cloth belt after sticking film and original cloth belt will have difference, cannot take the color of cloth belt after sticking film as decision reference object.
6) Different materials: especially for nylon and injection molding products, because the materials of teeth and cloth strips are different, the absorption capacity of dyes is also different, leading to the possibility of color difference between chain teeth and cloth strips in mass goods;Nylon zipper teeth are made of single silk, and injection molded zipper teeth are POM (polyformaldehyde), and their colors may also be different.The pull head is not the same material as the cloth belt and chain teeth, so the color difference may also occur.These are all normal phenomena.
Like: Metal teeth zipper
Nylon zipper for protective suits:
Points to note before placing an order:
1) Understand the color light source and identify the color light source required by customers.
Common light box color light sources are:
D65 light source (Artificial Daylight 6500K) : It is the most commonly used Artificial Daylight in the standard light source with a color temperature of 6500K.The D65 light source in the standard light box is to simulate artificial sunlight, so that when observing the color effect of objects indoors, cloudy and rainy days, it has a lighting effect similar to that observed in sunlight.
CWF: US Cold White Store light (Cool White Fluorescent) — Color temperature: 4150K power: 20W
TL84: Store light source — Color temperature: 4000K Power: 18W
UV: Ultra-violet — Wavelength: 365nm Power: 20W
F: Light for family hotel — Color temperature: 2700K Power: 40W
There are also fluorescent lamps and natural light.
Therefore, before proofing or bulk goods must be clear customer requirements of the color light, the color light has a great impact on the determination of color.
2) Reduce or avoid the direct production of mass goods for customer supply cloth plates, guide customers to make AB samples first, and carry out production after confirmation.
3) Timely explain the situation that the same dyeing depth and brightness cannot be achieved, such as the situation that the customer color sample is fleece, reflective fabric, transparent fabric, etc., or for the waterproof zipper, it should be clear that the color matching is based on the color of the cloth belt without the film.
The above summary is only some of the main situation, I hope to be helpful to you, the specific operation also need to be fully considered.Thank you for reading.
