Compared with the domestic application of the newspaper and commercial printing prepress technology, prepress technology newspaper printing has the following characteristics: First, in order to pursue technical security, thus overly conservative to technological innovation; Second, the blind pursuit technical security, resulting in the configuration and match equipment and applications software is not enough scientific and rational; the third is, so far still not used to regulate the flow of consciousness work, still stuck in the "heavy hardware over software," the awareness stage. The main reasons for the formation of these features has three points: First, the relative commercial printing, newspaper printing more attention to technology security and political security, which is the inherent characteristics of the printing press, it is difficult to change; Second, the technology used in newspaper printing Hengli label printing, especially software, relatively closed, difficult integration of other advanced technologies; third is that there is little domestic suppliers were willing to do to promote technological innovation newspaper prepress work, because the process would be more driven long and difficult. To change this situation the newspaper prepress technology, the most important thing is to change the newspaper prepress closed for openness. Once the elimination of technical barriers conservative, Zhangmutou label printing, make excellent pre-press technology used by newspaper printing, newspaper printing practitioners will emancipate the mind, dispel fears of technology security, which can boldly introducing new concepts, models and technology. From various international manufacturers in the country has launched a newspaper flow point of view, Qishi label printing, such as Agfa, Kodak Polychrome, Kraus, without exception, to 1-bittiff RIP as the data foundation after, so many well-known manufacturers to RIP way to build the press after the data flow, label printing, indicating at least one reason, RIP after the technology has a unique advantage in the newspaper, in the following areas. * Security. PDF security than the PS, 1-bittiff off than the PDF security. For newspaper printing, when the forum is determined by the editor into the plate-making process, the changes to the file is no longer needed, PDF editable here useless, it became a security risk. 1-bittiff can not be modified to ensure that the file is absolutely safe. Printing ghosting example of troubleshooting the company purchased a new type PZ-41020B off four-color offset press. After the machine in place, try to print stage ghosting phenomenon. After repeated testing, it has been difficult to effectively address. Symptom: analysis of printed products after the discovery, ghosting mainly in black and intermittent. Sometimes there are some local character a little, but not too obvious; sometimes the entire layout has, and it is clear and there is no law. Troubleshooting: Check the paper and pads are no problem, blanket cutting and installation is also very standard, so the factory technical personnel presumably the spring roller jaw fatigue and decreased elasticity, resulting in inconsistencies open bite during the action. All gripper drum spring all removed and replaced with excellent performance imported spring, the result fault persists. Then all the units cover all open, according to the group by checking the printing color sequence K → C → M → Y, and found the imprint impression cylinder sleeve K color group generated a slight loosening, with the gap increase, the re After the assembly location, failure to exclude. Failure Analysis: assembling accuracy of the machine is not enough, will produce jitter during operation, resulting in around the remaining black ink on the blanket cylinder K color group imprinted inconsistent, which occurred ghosting failure.
