The computer-to-plate technology CTP has brought a lot of problems involving workflow. Although eliminating the fact that the film can greatly improve the overall quality of its outlets and achieve better printing results, it has created a problem of responsibility.
Especially in the Hong Kong market: The output center is responsible for exporting the film, and the printing plant is responsible for printing and printing. Although CTP can bring more accurate and ideal printing quality to printing companies, the relevant production workflow has led many small and medium-sized printing companies to deter this new technology. This is not difficult to understand, because Hong Kong’s output center is closely linked with designers, advertising agencies and printing houses. They have mastered all the technologies exported by the film, which are lacking in general printing plants. Based on the similarities between the output film and the output plate technology, it is reasonable to conclude that the CTP workflow is an easy step for the output center.
If the CTP workflow is separated from the computer platesetter, there must be some digital solutions to ensure that the prepared data is reliable from the workflow (ie, the output center - transported to the exposure module - the printing plant), and the reliability must be consistent with Films work in similar ways. The emergence of screenedbitmap-1-bittTIFF, which can be used to transmit and store data, can provide CDRoms, tapes, or hard disks that have the same reliability as film output, can't change file content, and can be easily stored. With the appropriate workflow tools, users can preview overprints, overprints, and even the dots and screen angles of each color separation layout. So 1-bittTIFF can actually be called "digital film." Through some software, users can do some of the traditional film modifications of these "digital film", such as: a small amount of modification and drying.
Although 1-bitt TIFF has a series of advantages, it also has its disadvantages. When you encounter a large file (more than 3GB) in the format (30.31" x 40.55"), if you maintain the original film work mode, there will be some difficulties in data transfer. Fortunately, today's advanced file compression technologies, such as CCITT Group 3/4 and some patented compression hardware, allow larger data to be compressed into smaller files without loss of data integrity. That is to say, after compression, there is no loss of image quality at all. For general text and image pages, the compression ratio is approximately 1:15. Therefore, a 2400dpi split surface, after compression, each splitter file size is 60MB. Such file sizes can easily be transmitted via CDRom or peer-to-peer networks.
Based on the nature of digital files, 1-bittTIFF does not need to be stored in a larger space like a normal film. Because it is a digital format, it is very convenient to search for files by a computer. When each printing plate is rebuilt, the exact same effect can be obtained, eliminating the variables that may be brought out by manual re-lighting. In this way, 1-bittTIFF can provide very good connections for output centers and printing plants, providing faster and more reliable operation in the same way as film output. In other words, printers lacking experience in electronic prepress operations may also consider using only direct platesetters and collaborate with an output center that has a "digital film" 1-bitt TIFF output. This not only eases the investment of the printing plant in the establishment of CTP, but also creates a situation in the market.
