At present, RIP has become a core issue in prepress production. It affects every aspect of the entire production process, from color and document management to printing. Moreover, features such as trapping and layout that previously required separate application processing are now added to RIP.
There are many new RIP products and vendors. Like Agfa, Halequin, Rampage, Scitex, t UFO Suppliers such as Systems, which have been stable for a long time, have introduced new or updated hardware and software RIPs. Amiable, Colorbus, EFI, Vivid Image, Xante and other companies have launched their new large format and color copier RIP into the graphics industry. Adobe also offers an updated PS printing language and a PDF format that is expected to be a workflow file format for publishers with powerful, flexible tools that can be easily integrated into today's workflows.
With the development of science and technology, the use of technology in the printing industry is becoming more and more automated, and the requirements for computers and software will also increase, and the corresponding requirements for RIP software will be intensified. In order to meet various requirements, the development of RIP software must also have a clear direction. For now, the development trend of RIP software has the following points:
1. Support for the latest PostScript version: The current latest version is PostScript 3; PostScript 3 Added the following content based on PostScript Level 2: trapping (In-RIP Trapping), gradient (Smooth Shading), multi-format font support (Font), enhanced device control (Device Setup), etc.; conforms to PostScript 3's RIP will provide direct support for trapping, grading, and high-fidelity color, enhancing the ability of layout software to describe complex layouts and the speed at which RIP outputs complex gradients;
2. Support the latest portable document format PDF{Portable Document Format};
3, support the latest hardware and software platforms (such as 64-bit hardware platform and Windows NT5.0, etc.) to maximize the performance of the operating system platform, improve RIP output speed;
4, provide cross-platform support capabilities Not only can handle MAC, PC platform output tasks, but also accept output requests from other platforms such as UNIX;
5. Support PDF as the core automatic output process management system Development to improve system reliability, operability and production efficiency;
6, support for the pre-warning (Pre Flight) function of the print task;
7. Support intelligent assignment of jobs between multiple RIPs and output devices to improve system throughput;
8. Allow the user to query the status of the output system (printing task, RIP and output device);
9. Support users to remotely monitor the output system (printing task, RIP and output device);
10. Provide report function;
11, support OPI (Open Interface);
12. Support system hierarchical authority management to improve reliability. The current RIP can be divided into the following types according to different functions:
First, the RIP process is divided into two independent stages: rasterization and screening.
Introduced by Rampage's Rampage RIP. Rampage RIP is characterized by dividing the entire RIP process into two independent stages of rasterization and screening. After the input resolution, the image is rasterized, and then saved, and finally a dedicated screening board is used in the screening stage. High speed output at the required resolution. That is to say, there is a rasterized data on the disc that has been compressed at a high magnification without being screened.
It has the following features:
Since the rasterized data is present on the disk, "RIP once, output multiple times" can be realized;
Allow last minute modifications to a page that has been spelled out in the big version;
If the system is to be connected to a new imaging device, the original rasterized file can be taken out from the disk for output without re-rendering the file;
If a film or plate of a certain color is damaged, it can only scan and output this monochrome film or plate, saving time;
If it is necessary to change the original printing machine or printing paper at the last minute, it is only necessary to change the compensation value of the dot enlargement without re-rasterizing the entire operation;
If the imagesetter or the platesetter is faulty, Rampage RIP can also continue to rasterize the file and temporarily store the processed data in the disk until the imaging device returns to normal. Some famous imagesetters and CTP manufacturers such as Creo, Screen, Agfa Usa, Presstek, Gerber, Optronics, Krauss, Purup, etc. are all using or using Rampage RIP. Huakang's Dyna RIP and RampageRIP are value-added products from the same technology source and with perfect double-byte processing capabilities.
