Commercial Advertising Printing Technology Analysis (I)

With the development of economy, high-end printing technology has been applied to many fields. For high-end commercial advertising prints, it can better reflect the quality of products, attract consumers' attention, and play an important role in promoting product sales growth and market development.

In the past 10 years, the commercial printing market has been gradually formed and developed rapidly. The market share has rapidly increased from less than 1% 10 years ago to the current 15%. At present, high-end commercial advertising prints are mainly used in administrative prints such as luxury cars, senior cosmetics, fashion consumer electronics, communications, IT technology, high fashion and luxury goods industries, and some of the world's top 500 corporate annual reports. High-grade commercial advertisements and other printed materials have beautiful pictures, coordinated pictures and pictures, and high picture clarity. The pages are neat and smooth, and the reading and turning pages have a good feel. The binding and exquisite design give people a beautiful enjoyment.

The amateurs watch the excitement and the insiders watch the door. The so-called high-grade prints can not only be a certain link, a certain process can be upgraded as high-grade prints, but also must be matched with each other on a multi-layered surface in order to be called a boutique. This article will summarize the characteristics and process technology of high-end commercial advertising prints from the perspective of specific technology.

Prepress processing

1, the original collection

Printing is the reproduction of manuscripts and the re-creation of art. From the point of view of elements, one of the most important prerequisites is high-quality manuscripts. The manuscript here refers to electronic manuscripts or photo manuscripts. It is mainly for actual real-life images. The pictures are all large-scale reversal films or high resolution digital photos. Of course, some of them are generated using 3D industrial design software, but the premise is based on the high-quality picture materials obtained by the aforementioned methods.

For this reason, it takes a lot of money to prepare the manuscript, such as hiring a professional photographer and using top-level photographic equipment. The manuscript created in this way is not only saturated in color, but has an appropriate contrast. The most important thing is that it is excellent in definition. High-quality manuscripts have laid a solid foundation for the creation of exquisite high-grade prints.

2, proofing and color management

In the all-digital prepress environment, the reduction of the original color of the picture and the control of the color of the re-created manuscript are the biggest difficulties. In theory, when the original is collected, if it is an electronic manuscript, the color space described by the color light mode is larger than the color space where the ink can be restored on the paper. Therefore, a part of the color must be compressed. In addition, when the original is collected, there will be errors in the recording of the color. If there is no good way to correct this error and use it for color separation printing, the final color of the final product must be far from the original.

If it is a manuscript created using a computer, there is not a display that is highly consistent with the print based on color data, and it is difficult for a designer to grasp the true effect of his creation. The prepress system, which uses a color management system (CMS), automatically compensates the display based on the characteristics of the device at each stage of the printing to more accurately simulate the final product.

3, prepress and printing, post-press technology

CTP adopts standard technologies to ensure that the network points are restored to the maximum extent possible. JDF is also a mainstream technology that can describe all production processes from the submission of job tasks to prepress, printing, and postpress. The method is to convert every step in the production of a job into a node in a JDF file. A JDF node is an XML element and can be related information about the production process, such as staples, folding, cutting; it can be related to Product information, such as the final print, can also be both.

Through the pre-setting of the pre-press stage, the later production process can be made efficient and automated, and the failure caused by human factors can be reduced. These two technologies have been widely adopted in developed countries and provide good conditions for the production of high-grade prints. (To be continued)
