Application and advantages of rip
at present, rip has become the core issue of prepress production. It affects all aspects of the whole production process from color and document management to printing. Moreover, functions that previously required separate application processing, such as trapping and collage, have now been added to rip
there are many new rip products and vendors. Suppliers such as Agfa, halequin, rampage, Scitex, t UFO syst and EMS, which have been stable for a long time, have launched updated or new models of hardware and software rip. Amiable, colorbus, EFI, video image, xante and other companies have launched their new large format and color copier rip and entered the picture industry. Adobe also provides publishers with powerful, flexible tools that can be easily integrated into today's workflow with an updated PS printing language and a PDF format that is expected to become a workflow file format
with the development of science and technology, the application of science and technology in the printing industry will become more and more automated, and the requirements for computers and their software will also increase, and the corresponding requirements for RIP software will also intensify. In order to meet various requirements, the development of RIP software must also have a clear direction. At present, the development trend of RIP software is as follows:
1. Support the latest postscript version: the current latest version is postscript 3; Postscript 3 adds the following contents on the basis of postscript Level 2: in RIP trapping, smooth shading, multi format font support, enhanced device setup, etc; Rip in line with postscript 3 will provide direct support for trapping, gradient and high fidelity color, and enhance the ability of typesetting software to describe complex layouts and the speed of rip to output complex gradient layouts
2. Support the latest portable document format PDF {portable document format}
3. Support the latest software and hardware platforms (such as 64 bit hardware platform and windows NT5.0, etc.) to give full play to the performance of the operating system platform and improve rip output speed
4. Provide cross platform support, which can not only handle the output tasks of MAC and PC platforms, but also accept the output requests from UNIX and other platforms
5. Support the development of automatic output process management system with PDF as the core to improve the reliability, operability and production efficiency of the system
6. Support the pre flight function of print tasks
7. Support intelligent job allocation between multiple rip and output devices to improve system throughput
8. Allow users to query the status of the output system (printing made me, the SAR government and the general public of Hong Kong extremely disappointed with the task, rip and output equipment)
9. Support users to monitor the output system (print job, rip and output device) remotely
10. Provide report function
11. Support OPI (open interface)
12. Support hierarchical authority management of the system to improve reliability. Now Rip can be divided into the following types according to different functions:
first, divide the rip process into two independent stages of rasterization and addition
take rampage rip of rampage company as a representative to make an introduction. The characteristic of rampage Rip is to divide the whole rip process into two independent stages: rasterization and addition. After the input resolution, the image is rasterized, and then saved. Finally, in the addition stage, a special adding board is used to output at high speed according to the required resolution. In other words, there is a highly compressed and unprocessed raster data on the disk
it has the following functions:
because the rasterized data is stored on the disk, it can realize "rip once, output many times"
it is allowed to make last-minute modifications to a page that has been spelled in the large version
if the system wants to connect to a new imaging device, it can take out the original rasterized file from the disk for output, without re rasterizing the file
if the film or printing plate of a certain color is damaged, only the monochrome film or printing plate can be scanned and output, which saves time
for example, StarTech designed a full-automatic tensile testing machine system. As a result, it is necessary to change the original selected India a at the last minute and analyze the differences between the old and new standards; For brushing machine or printing paper, only the compensation value of point expansion needs to be changed accordingly, without re rasterizing the whole operation
if the imagesetter or the direct plate maker fails, the rampage Rip can also continue to raster the files and temporarily store the processed data in the disk until the imaging device returns to normal
some famous imagesetter and CTP manufacturers such as Creo, screen, Agfa USA, pressek, Gerber, Optronics, Krauss, purup, etc. are using or choosing rampage rip. Huakang's dyna rip and rampagerip are value-added products from the same technology source and have perfect double byte processing capacity
