The interaction of color, from people on the consciousness and the psychological effect of color, use the scientific analysis method, the complex phenomenon of color reduction as the basic elements, use of color in the space, can change on the quantity and quality, according to certain rules to each level of the relationship between, and the process of creating new colour effect.

Color composition is one of the basic theory of art and design, it has an integral with planar and three-dimensional construction, the relationship between colour cannot be separated from the form, space, location, area, such as skin texture and independent existence. We know that the object's color is the results of light reflection, so, the colour of computer display how to generate?

Color displays produce similar to the nature of the light color. Inside the display has a like the TV picture tube, the electron flow is emitted when the gun inside the tube at the phosphorescence piece on the inside of the screen, phosphorescence is luminous effect. Three different properties of phosphorescence piece respectively emit red, green, blue three kinds of light, a computer program to quantitatively control the intensity of electron beam, the accurate control the phosphorescence of the wavelength of light waves, through the synthesis of overlay, can simulate all kinds of colours in nature.

Toner is a colored powder material, mixes with plastic pigments, through heating injection plastic products of various kinds of different colors. It is widely used in plastics coloring process. Generally speaking, there are blue, orange, green, black, yellow, red, purple, pearl color variety of color, etc.

Advantages:

1, the price is cheap, economical and practical.

2, proofing time is short, fast production, can quickly finish color.

3, easy to transport.

4, suitable for a variety of products.

Disadvantages:

1, mixing powder pollution, mixing barrel is not easy to clean.

2, different materials, different brand or batch number and different operation conditions, equipment, die different operating temperature differences, in a different way, all will produce off color.

3, poor dispersion.

So the toner and color is the same field of different things.
