There are so-called three Cs in color management, namely Calibration, Characterization and Conversion. The description refers to how to record the color performance capabilities of input devices and printing devices, and how to turn these records into ICC profiles Format (ICCProfile) process, commonly used tools include: PrintOpen, ProfileMaker, ColorVision, Viewopen, ProfileWizard and so on. Conversion refers to how to perform color space conversion based on the data in the ICC profile on a certain device to achieve the purpose of color space simulation. If the device is a Mac computer screen, the conversion is performed by Colorsync in the system. If the device is a printer, the conversion is performed by a print server with a color engine installed. The more commonly used include: BestColor, BlackMagic, Startproof, Pressready, etc.
Calibration is not taken seriously
Color management is closely related to digital drafting, the former is theory and process, and the latter is specific application. At present, the most popular products in the color management market belong to the two Cs of description and conversion, and most of them are related to digital drafting, and the price ranges from $ 100 to $ 100,000. Since digital drafting is the most important part of the CtP production process, the attention of most printing companies is also on how to choose ICCProfile production software and how to choose a color print engine. Many seminars and seminars are also based on the demonstration of ICCProfile production and color conversion as the selling point. As for the first C (calibration) of color management, it was either taken lightly at the seminar or rarely mentioned. The system integration supplier also believes that printing companies have been working in the current printing method for many years, and naturally there is no problem. Therefore, when they produce digital ICC signature files, they assume that the printing machine has been calibrated. As for whether this assumption is true, and if this assumption is incorrect, they will have no effect on this. If the customer insists that they help calibrate the printing before doing ICCProfile, they will advise the customer to ask Gao Ming.
Is calibration important?
What level of calibration does it have and how will it affect printing companies? Few printing companies will think seriously. Moreover, there is no simple answer to answer. In fact, some printing companies use color management and digital drafting, mainly to save costs, and after reducing the film and drafting, there is a larger space for price reduction. For these printing companies, the calibration is not important, anyway, as long as the customer is willing to receive the goods, it is best not to prepare even digital drafting.
However, if the printing company adopts color management and digital drafting, the reason is that it hopes to have a more stable proof, which can cooperate with CtP technology to improve production efficiency.
