The display is an RGB display mode, which is composed of red, green, and blue light into various colors. Different displays and the same display show very large color differences in different environments. Offset printing is a CMYK presentation mode, which is composed of cyan, magenta, yellow, and black inks to form various colors. The color difference of the display is less than the combination of red, green and blue. Therefore, there will be a certain color difference between the non-professional monitor and the printed matter. Please do not use the color on the monitor to proofread or compare the printed matter.
2.About the color difference between the same batch
Due to the volatility of offset presses, there will be slight color differences between the same batch of printed matter. We use a pre-ink supply system to ensure that the color is within the fluctuation range as much as possible, but there will still be color differences 3.About Pantone Do not use three spot colors in each design file. Because the printing process of spot colors is more complicated than that of four colors, the color difference is greater than that of four colors
Q4: How to avoid chromatic aberration as much as possible?
A: 1.Please use professional design software, recommend using Adobe CS suite to complete the album design; 2.Before the start of the album design, check the color settings of the design software to ensure that the software configuration is normal; 3.Try to use as little as possible to produce obvious color difference colors, such as blue-purple, brown and then gray when designing, use black, avoid using three-color gray; 4.When using special paper, please try to simplify the design content, use more single-color, solid lines or text, and avoid large-area multi-color overprinting and four-color images. 5.The colors produced by screen software or inkjet proofing cannot be used as printing color samples. For those with strict requirements on colors, please provide standard printing color samples. 6.The same document is printed in different batches due to the ink control problem, and the color difference is different, and the color difference of about 5%-10% is normal.
