1 bit TIFF - film in the digital era

CTP, the computer direct plate making technology, has brought out many problems related to workflow. Although the elimination of phenanthrene can greatly improve the overall point quality with the advantages of fast cooling speed and low noise, so as to achieve a better printing effect, it has caused problems

especially in the Hong Kong market: the output center is responsible for outputting films, while the printing factory is responsible for printing and printing. Although CTP can bring printing plants more accurate and ideal printing quality, the related production workflow has deterred many small and medium-sized printing plants from this new technology. This is not difficult to understand, because Hong Kong's export center is closely linked with designers, advertising agencies and printing plants, They mastered Martin Martinez, "this is polydopamine (PDA)" Where you enter this game, all the technologies output by film are lacking in general printing houses. Based on the similar technology between output film and output plate, it is logical that CTP workflow is an easy step for the output center

if the CTP workflow is separated from the computer direct plate making machine, there must be some digital schemes to reliably transfer the prepared data from the workflow (i.e. output center - transmission to exposure component - i.e. printing plant), and its reliability must be similar to that of film. The emergence of screenebitmap-1-bittiff, which can be used to transmit and store data, can not only provide the same reliability as film output, but also provide CDROM, tape or hard disk that can be easily stored without changing the file content. With appropriate workflow tools, users can preview overprint, overprint, and even the point and screen angle of each color separation layout. Therefore, 1-bitttiff can really be called "digital film". Through some software, users can do some traditional film decoration for "digital film" if they are simply looking for a cheaper price, such as a small amount of modification and exposure

although 1-bitttiff has a series of advantages, it also has its disadvantages. When encountering folio format (30.31“ × 40.55 ") (more than 3gb) , if you maintain the original film working mode, there will be some difficulties in data transfer. Fortunately, thanks to today's advanced file compression technology, such as ccittgroup3/4 and some patented compression hardware, larger data can be compressed into smaller files without losing data integrity. That is to say, after compression, the image quality is not lost at all. For general text and image pages, the compression ratio is about 1:15. Therefore, for a 2400dpi folio layout, the file size of each color separation sheet after compression is 60MB. Such file sizes can be easily transmitted through CDROM or point-to-point networks

based on the characteristics of digital files, 1-bitttiff does not need to be stored in a large space like ordinary film. Because it is in digital format, it is very convenient to use the computer to find the file of the experimental machine according to the control and loading mode, and each time the printing plate is rebuilt, it can also get the same effect, eliminating the variables that may be brought out by hand redrying. In this way, 1-bitttiff can provide a very good connection between the output center and the printing factory, and provide a faster and more reliable operation in the same working mode as the Philippine output. In other words, printing plants that lack experience in electronic prepress operations can also consider using only direct plate making machines and cooperating with output centers with "digital film" 1-bitttiff output. This not only reduces the investment of the printing factory in establishing CTP, but also creates a win-win situation in the market
