Corporate brochures show the image of the brand, but also an important carrier to promote corporate culture, therefore, the quality of corporate brochures is related to the reputation and image of the enterprise. But unfortunately, even the most well-known printing companies, when printing, the color difference will appear more or less, some companies in the color correction has not passed, because many of the colors on the screen can not be printed at all, or have serious color bias, if not in the design stage to be corrected, until the finished product printed out too late. So how to control the color difference of the custom lift-up flaps book?

In order to prevent such problems, it is important to correct the color before printing. First of all, to carry out equipment calibration and system calibration, these devices include scanning equipment, display equipment, output equipment and proofing equipment, these devices have to undergo strict professional calibration, the other is to have a relatively perfect color management program between these devices, these are the basis for our color correction.

Then, level correction is performed before color correction. Because according to the color mechanism, the color is presented on the basis of neutral gray level, so the level should be corrected first and then color correction, otherwise, after the color correction is completed, the color will change when the level is corrected.

In printing, four-color inks are generally used, so the color is specified by CMYK, as long as CMYK is determined, it means that the ink proportion is determined, and the color is usually not too big a problem. However, the color in the computer is expressed in RGB mode, so it must go through a color conversion step, which is the key to prevent the color difference in the printing of the brochure.
