Improvement Measures Of Printing Quality

Image quality analysis, improvement methods and solutions are as follows:

1, image definition is not high.

The phenomenon is: the image is blurred; there are incomplete figures in the image: the fineness of the spray nozzle is not properly adjusted.

The main reason is that the ink jet resolution is not matched with the gray cloth.

The solution is: because of the weaving way of grey cloth, the surface can not be as smooth as paper.

Most inkjet printing uses 360 to 720dpi ink jet.

Silk fabrics and other fine fabrics are rarely inkjet to 1440dpi. If the image sharpness is increased indefinitely, it will not be effective.

And it will affect the increase of jet speed.

To increase the difficulty of software and hardware, we should choose the resolution according to the fineness of the flower pattern and the smoothness of the fabric. We should adjust the height of the sprinkler reasonably for different thickness of the fabrics: the nozzle is too low, so that the nozzle can be blocked, affecting the color of the pattern: the nozzle is too high, and the ink moves along with the sprinkler.

There is a certain height from the fabric.

It produces a parabola at a certain angle.

The boundaries of the printed patterns are blurred, the accuracy is poor, and the colors are not bright enough.

So when printing.

Adjust the sprinkler to the right height.

2, the color level of the pattern is not rich enough.

The phenomenon is: there are two injuries in the pattern, and the pition is not natural.

The expressive force is not strong, and the level is smooth because the dye ink is inappropriate or not suitable for the grey cloth.

The solution is: ink jet printing changes the color level by spraying the number of droplets.

Jet printing as spot printing.

It is no problem to show dark colors with high density.

Sometimes there is a sense of hierarchy.

Or because of the blending of more coloured dots, it is easy to produce a dull color and a bright color to reduce the problem of light color area.

It can produce better effect by increasing the density by using two kinds of shades and double pigments.

Another way is to mix colors in advance.

It's called spot color jet printing.

However, there must be a color matching system and an automatic pulp mixing system to support it.

And the register will be limited.

3. During the printing process, the surface grain size is coarse or the flow ink is generated.

It is formed by improper adjustment or damage to the ink jet port.

The solution is: the choice of printing accuracy.

Most of worsted fabrics are printed with high precision 720doi~720dpi.

Printing accuracy is directly related to printer resolution. Fabric printing is done with 720dpi resolution.

The accuracy is quite high, and the woollen fabrics of general woollen fabrics can be printed with 360dpi~360dpi accuracy.

This can improve printing speed.

And enough to satisfy.
