RIP processor explain (2)

Now RIP can be divided into the following types according to different functions:

I. Dividing the RIP process into two separate stages of rasterization and screening

Rampage RIP represented by Rampage. The Rampage RIP is characterized by dividing the entire RIP process into two separate stages: rasterization and screening. After inputting the resolution, the image is rasterized and then saved. Finally, a dedicated screening plate is used during the screening stage. , High-speed output at the required resolution. That is, there is a rasterized data that is highly compressed and not screened on the disc.

It has the following features:

* Because the rasterized data exists on the disk, "RIP once, output multiple times" can be achieved;

* Allows for the last minute modification of a page in a large version that has been spelled out;

* If the system is to access a new imaging device, the original rasterized file can be retrieved from the disk for output, without the need for re-rendering the file;

* If a film or plate of a certain color is damaged, it can scan only the single-color film or plate, saving considerable time;

* If it is necessary to change the original selected printer or printing paper at the last minute, only the offset compensation value is changed accordingly, and there is no need to re-rasterize the entire operation;

* If the imagesetter or the platesetter has a failure, Rampage RIP can continue to rasterize the files and temporarily store the processed data in the disk until the imaging device returns to normal.

Some well-known imagesetters and CTP manufacturers such as Creo, Screen, Agfa, usa, Presstek, Gerber, Optronics, Krauss, Purup, etc. are all using Ramp RIP. Fukang's Dyna RIP and Rampage RIP are value-added products that come from the same technology source and have improved double-byte processing capabilities.

Second, separate the RIP process from the entire output process

AGPAN's Taipan RIP for WINDOWS NT belongs to this category. It can store good RIP documents on the disk, allowing users to preview the text, images, traps, and impositions of the documents before scanning the plates. Zooming to observe the panoramic image, displaying the synthesis of separation colors (including spot colors, dot angle conditions, ink coverage, etc.). The exported documents can also be stored in the RIP so that the exact same plate can be taken out and output directly at a later time without further rasterization.

Tai;an RIP can run on dual-CPU workstations, and can complete two tasks at the same time, such as the output of a document at the same time, start RIP next document. It also has a spooling function that can complete more tasks in each shift. Taipan RIP supports various resolutions, screening methods, and output sizes. Through the pre-check, the user can determine whether the print output will be immediately output or whether the output will be postponed or backed up.

Third, adding an open intermediate format to the RIP process

Linotype-Hell's Delta RIP and Harlequin's scriptWorks are examples of this. The entire Delta RIP consists of Delta software, Delta Tower, and DeltaWorkstation. The Delta RIP is an all-in-one system. The most significant feature of the Delta technology is the introduction of an intermediate format called Delta List between interpretation and rasterization.

The Delta List format is open and has the following effects:

1. The other RIP suppliers can also make a Delta List and connect the Delta List to the output device's Delta Tower processor for output.

2. Allows third-party developers to write an application into the Delta List for tasks such as patching, imposition, and color proofing.

3. Allows the Delta RIP driver to be a non-"Linotype-Hell" output device. Other vendors only need to develop a program that can read the Delta List format and write an interface to its output device.

In this way, in addition to the usual print queue management, image management, and OPI service functions, the Delta RIP system also provides functions such as trapping, proofing, imposition, and off-line production. The Delta List allows the output device to run at full speed while using the specified hardware processor and the specified output device. One of Delta's technologies is "RIP once, output multiple times". The Delta RIP can be used with the Linotype-Hell dedicated layout workstation, Signastation, Digital Proofing FormProof, and servers and databases to meet multiple requirements in digital workflows.

Harlequin's scriptWorks also has a Display List Access set between interpretation and output imaging. It allows OEMs and third parties to write specific applications for users and put these applications into scriptWorks to enhance their respective systems. In addition to patching, previewing, etc., Harlequin Fine Screening (HPS) is also included in the scriptWork RIP. HPS can reduce or eliminate moire. It can also choose the dot angle and frequency to get the desired result. The ScriptWork's "ExtraGrays" feature can be used in conjunction with the HPS to extend the grayscale of each color. ScriptWorks overlaps input, interpretation, and output, meaning that when a document is interpreted, a previously interpreted document can be output from a selected device, and the next document can be received. In many cases, this means that the output device can run at full speed without pausing between pages or print jobs. ScriptWorks compresses and exists on the hard disk before sending it directly to the output device. This saves time on the one hand than storing the original uncompressed print job. On the other hand, when an additional product or machine needs to malfunction, it is not necessary to reinterpret the job because all the dot matrix data is stored on the disk. It is easy to re-export. If you need to reorder pages, you can stop the original page from being interpreted again when you interrupt the printing of a page and reprint it during the process.

ScriptWorks is also fully compatible with PostSrcript Level 2 and promises to be compatible with PostScrimp Level 3. ScriptWorks handles PDF 1.2 documents. The scriptWorks and workflow supports such input formats as PostSrcript, PDF, and TIFF/IT-pl. In a mixed workflow environment, it is not possible to perform seamless and efficient processing of PDF prints.

Fourth, accept PostSrcript and PDF documents at the same time

AGFA's Taipan AX RIP for DEC is similar to the Taipan RIP. The difference is that it can accept Postscript and PDF documents at the same time. It can also convert some of the less efficient PostSrcript Level 2 operations to a higher quality, faster PostSrcript Level. 3 Operation Taipan AX RIP can be applied to the existing PostScripp1 process and replace the existing application software. The Taipan AX RIP runs on the DEC 500MHz Aplpha processor to meet DTP users' needs for RIP in terms of speed and reliability.

Fifth, Intelligent Agents intelligent interface process

Harlequin developed the EP2000 RIP after launching its RIP management system, scriptWorks 4.0, using Agents (interface processes) to adapt the workflow.

As today's digital printing and publishing workflows are becoming more and more complex, the choices of input media, file formats, postpress submission methods, and output and delivery methods are diverse, and production decisions must also take into account the gap between Large-format, color models and proofing, coupled with the need to meet customer needs for delivery, price, quality, and workflow re-arrangements, are the last minute changes, urgent tasks, and even equipment damage. The situation is always there. In order to deal with these variable factors, you need an advanced intelligent software. EP2000 was developed to meet this demand. It enables systems that work in digital production environments to intelligently and automatically optimize themselves to suit changes in the production environment based on the user's preferences. Harlequin's OEMs can also form a system to enable flexible control of all aspects of the print production process to meet the needs of users. EP2000 can also provide the ability to drive a variety of output devices; for example, color pages can be sent to different output devices as required, such as color proofing machine, signature proofing machine, and proofing proofs, and finally output to a On the station or multiple photo-setters or plate-making machines, the original file can also be converted into HTML and sent to the website. The EP2000 has the function of Interpreter/Rasterize Many (Interpreter/Rasterize Many). Unrelated formats are stored; later, different resolutions and color corrections can be used to rasterize multiple times for different devices. The EP2000 can also have selective processing functions. For example, it is only necessary to send the page that needs proofing to the proofer. The EP2000 also has a last minute modification function. (The full text is unfinished.)
