The ink control system generally consists of three parts, namely the ink fountain control module, the ink control console, and the ink control software. The ink fountain control component is a group of ink knife opening degree control components and circuit systems designed to control the amount of ink according to the size of the printing machine. Its role is to guide the motor to control different ink knife opening degrees through the circuit system, so that the ink fountain roller is The thickness of the ink is varied to achieve a change in the amount of ink required in the ink system in a given area.
The ink control console is an operation platform for data acquisition, data correction, data backup, signal conversion, ink fountain control and quality evaluation. Its role can be configured according to different levels to complete the following combinations of different functions. Collect the ink signal data, correct the original data according to the type of equipment, environmental conditions, material selection and other factors, pass the corrected signal to the printer and form the ink knife opening control, and at the same time the ink control The console can use the standard or specified observation environment to perform visual or instrument quality evaluation of the print sample proofs and proofs to form print correction feedback to achieve the quality control of the printing process.
The main body of the ink control software may generally include three parts. One is a CIP3 ink channel data preset software (generally referred to as a preinking software or a preinking system) that can perform preset calculations on the opening degree of a printer ink knife. Its information acquisition method is diverse, that is, it can directly read the RIP after the text data (1-bitTiff file), according to the size of the plate and the number of ink keys to determine the machine control ink zone information, but also through the PPF file The information in the ink area information, and then the information is recorded on the media, printed on the paper or directly converted to the printer ink control component signal for the printer's ink key preset, thus ensuring a higher data prefabricated Accuracy improves the rationality and accuracy of the distribution of printing ink zones. The second is the control software that operates the ink knife opening control. Its function is to perform various operations of ink knife control through software, among which there may be the ink knife opening operation directly controlled by the general operation table, and also the maintenance operation such as zero point setting and correction, remote maintenance of the ink knife system. Wait. The third is the quality control software of printing quality. Its function is to measure the printed matter through the selected instrument. It can be a full-page inspection or a partial inspection. It can be a colorimetric inspection or a density inspection or a chromaticity plus density. Detection can be quality inspection or defect inspection. Different inspection purposes should match different inspection instruments. For example, the full-page inspection needs to match the full-page scanner, and part of the detection mainly refers to the detection of the test-and-control strip. At this time, the densitometer or the colorimeter can be selected according to different requirements. At the same time, the print quality control software should also have the function of dynamic ink control. There are many factors affecting the change of the ink channel data in the printing process. The print quality control function in the ink control software is used to obtain the relevant information, and the printing operation conditions are combined. The ink channel data of each ink zone is dynamically controlled.
Although a complete ink control system can have multiple components, it can be configured according to different user requirements in practical applications. For example, for ink control software, if the printer application manufacturer does not use the process for production, or is not equipped with PPF generation. The system, you can not need ink data preset software but only ink knife control software.
Another example is the ink control console. If the printing press application manufacturer does not perform data quality quality control requirements for the printed matter, it is not necessary to add a quality control module during the configuration process. Therefore, a complete ink control system should have a modular structure, which can match different functions according to different printing needs. At the same time, it should also be able to be upgraded or modified according to changes in demand. For example, an ink control software that has not been added to the quality control module should be able to implement the control function through the convenient hardware technology transformation and the opening or upgrading of the software function after the print control requirements appear.
