Why is the printed image different from the color in the computer?

Why is the printed image different from the color in the computer? This is called color difference!
There are always customers doubt: why is the color printed out different from color in computer ? In fact, this problem is very simple, that is, two words: color difference. So today, let's talk about the color difference problem and the solution.


1, monitor caused color difference.
Because the LCD screen is widely used at present, which is characterized by bright colors, high brightness, better visual effects. In actual output inkjet printing process, Ink is not the same color as the screen. Moreover, the printing machine is automatically identified and sprayed according to the CMYK color value setting, This will lead to color difference.

When designers use large amounts of cool colors or dark colors. after the sum of the CMYK values exceeds 260, the chance of color deviation will be high.
In fact, when choosing a display for designers, if you choose LCD display, be sure to choose IPS hard screen display, do not choose soft screen,  the biggest feature of IPS screen is:From the front of each angle, the monitor color will not change, and the color restoration is better.CMYK colors are not high saturation as RGB color, you can only try to close to the RGB color in the later adjustment, but definitely not the color of RGB.

2, software caused color bias.

Designers commonly used software are PS, CDR, AI, very few use INDESIGN, When the design picture needs to be finished, Building pages can create RGB colors, The best to do is to create CMYK colors, In this way, the real effect is clearly understood at each step,The RGB color is also converted to the CMYK color value when it is finally made. PS, CDR, AI, these three software, CDR is the closest to the actual color, PS, AI two software color difference are slightly larger. But this is not absolute, also depends on the specific design content.


3,machine different.
the color will be biased. Different printers work out the same picture, there will be color difference. and more, color difference occurs at different time in the same machine.



4, ink caused color quality distortion, partial.

If clients use the same brand ink, long term cooperation, reliable quality, should be fine for the color. However, occasional color error caused by incorrect cartridge installation.


Above is basically the reason for the color difference, In fact, in actual production, it is almost impossible to achieve the conformity of the finished product with the design draft, only the greatest degree of access, so how do you achieve the maximum degree of approach ? will the color difference be minimal?


1. Use a high quality monitor whenever possible, or use the monitor as much as possible when you look at the manuscript.
2, design companies and production companies as much as possible to use the same version of the design software, it is best to use CDR software.
3, designers try to minimize color strike effect, avoid a lot of dark color.


In fact, in addition to color difference, there are many problems in the design which will affect the synthesis of the latter image. this is only the most common color difference,In the process of printing, designers also need to continue learning, accumulate working experience to present more perfect works to clients.
