In practical production, there are many factors can affect the printing copy quality.
GCR color separation suit the original of dark tone is larger, mainly gray, auxiliary color, such as traditional Chinese painting, print, mechanical figure, etc.
Conclusions Color image color separation parameter settings, To consider the characteristics of the image and printing paper, ink, printing equipment and so on various factors.
And according to the properties of the original and late printing environment set different color separation parameter in the Photoshop, to achieve the best printing quality.

To separate such a mixture its use different methods, which are chosen taking into account the nature of the system and its properties (phase discontinuous nature, size, temperature etc.) [1,2,3].
The process of sorting mixtures of particles per sieves is influenced by many factors, of which the most important are [4,15,16,17,18,19,20,21]: a) screen: sieve loading; sieve size; size of the sieve holes in the screen; kinematical regime (of movement) of the sieve; b) for the material which will be sorted: the granular component of the material to be sorted; the difference between the size of the particles to be sorted; the nature of the particles to be sorted; the moisture of the particles etc.
Conclusion The separation of solid particles after size is a complex process influenced by several factors, which depend of the particles and characteristics of equipment used.

Functionally graded materials (FGM) are materials with varying electrical, chemical, mechanical, magnetic, thermal properties over the volume of the bulk material.
The continuous variations in the properties of FGM along a specific axis are based on different factors including porosity and pore size, chemical and microstructural gradient-structures.
Moreover, due to the varying physical properties of FGMs, it is used for a wide range of applications including nuclear, automobile structure, aerospace, and optoelectronics.
The physical properties of solid as well as fluid are constant, the fin temperature variation is assumed one-dimensional and steady.

After getting the MARS results of mathematical expression, we can screen the factors which benefit to the response variable by individually analyzing the internal relations between them and analyze the importance of factors with investigating the contribution of each factor to the response variable to facilitate decision-making.
While in the material processing field, only Taylor and Francis [9] analyzed the mechanical properties of steel by MARS method currently, and no scholars apply this method to calculate and forecast the flow stress.
For testing the effect of a certain factor on flow stress, the common methods set other factors as constants that usually are averages.
The importance of various factors to flow stress could be analyzed through the MARS model.
Conclusions (1) Using MARS algorithm, the fit of the relations between flow stress and the influence factors is good.

Non-dominant point approach was applied to find optimal combination of different factors affecting the process performance.
