How to choose RIP correctly

With the rapid development of digital color output operations and the increased demand for high efficiency of prepress operations, more and more printers are realizing that there will be no suitable RIP in the output process. Get high quality output. In fact, choosing an inappropriate RIP will hinder the productivity of digital output devices.

Of course, for commercial office equipment such as pure text printing, when selecting RIP, the difference between different types of RIP becomes more important; for digital print output devices, choose one for them. Proper RIP is a very critical issue. The use of RIP by most printers is limited to the direct or indirect installation of this process inside the computer or inside the digital printing device. At present, although RIP has many advanced printing technologies such as color reproduction or color printing, large format printing, and digital color printing, the technologies supported by different RIPs are different. Therefore, in order for the output device to obtain high-quality output, the printing plant managers must carefully select an appropriate RIP for their prepress operations to meet their needs and applications.

So what exactly is RIP? Simply put, the RIP is a device that converts the data to be printed or desired to be printed into a raster image or a dot matrix that can be output to paper or film using an ink jet printer or a laser output device. RIP is located at the back end of the pre-press workflow and is an intermediate process at the beginning of printing. In this process, RIP accepts print data described or vectorized in page description language. In fact, the commonly used page description language is the Postscript language. It mainly describes in function the "what is the output object" and "what position the output object should output to the page". The role of RIP is to convert the Postscript description of the "contour" command into a dotted line format, and then arrange them on the page in a certain order.

In addition, for RIP used in color printing or laser output devices, RIP plays a role in how to improve the accuracy of color reproduction. Therefore, the requirements for this type of RIP are: First, the RIP must be able to interpret the color of each element on the page; secondly, the RIP can convert the color-related information into the color mode needed for printing or printing.

So, what aspects do we need to pay attention to when choosing RIP? In general, there are so many factors to consider when choosing a RIP. First, and most importantly, is the structure of RIP, that is, you need RIP is software RIP or hardware RIP, or still need a RIP card; Second, you need to consider the basic functions of RIP, that is, the speed of RIP, RIP required The level of color management software, etc. The last is the cost of the required RIP.

RIP structure

When choosing RIP, make sure that the structure of your chosen RIP meets the needs of your job. In general, the following points should be considered in the structure of RIP:

1. The combination of hardware and software RIP is usually provided as a complete whole to the user, it contains a computer (dedicated computer) and RIP software. At the same time, the hardware and software that merchants provide to users are all optimized and processed, with the best processing results and the best work performance. Although some hardware RIPs can be upgraded, special components, such as memory, are still required during the upgrade process.

2. Software RIP

Software RIP is an optimization software that is responsible for image conversion. Whether on a PC, Mac, or Unix workstation, the purchaser can select the most suitable software RIP for his computer system. The greatest advantage of using software RIP is that the user can use the computer's standard components. Upgrade the software RIP or upgrade the software RIP after purchasing a new computer. The unfavorable aspect of software RIP is that software RIP cannot be optimized when it works with hardware RIP. Therefore, the performance of software RIP cannot be equivalent to a specialized RIP system.

3. Interpolation RIP

Interpolation RIP is actually a hardware RIP made of a computer-specific card, this RIP can be inserted inside a digital printer or laser output machine. Its biggest advantage is to reduce the volume occupied, saving board space. Despite this, interpolated RIP also has its disadvantages: it can only support one output device, and it is also difficult to upgrade.

4. Supports page description language RIP

Although the most common page description language in the current prepress production environment is Postscript, in your work, you may often want to use other file formats, such as PDF, TIFF, or other proprietary file formats. So in the process of choosing RIP, make sure that the selected RIP can handle all the file formats you need.

5. Support printer RIP

Maybe there is a need for a dedicated RIP in some specialty stores, while RIPs that can support multiple printers are also being sought at the factory or in some stores that need to print out the amount bills. This type of RIP should be able to adapt to a variety of different environments, for example, companies that need color copies and companies that need large-format printing. In addition, printing costs can be greatly reduced by using a method that supports multiple printer RIPs.

RIP function

Once you have determined the RIP structure that will meet your work needs, the next step is to get your chosen RIP to have the features you need. The following points need to be considered in this regard:

1. RIP speed

The speed of RIP is a key technical indicator for printing houses and some printing companies. However, the speed of RIP depends on the hardware and software of the computer, and it also depends on many other factors, such as the number of color separations, the resolution of the image used in the RIP process, etc. These factors will all seriously affect the speed of RIP. Therefore, when evaluating the speed of RIP, it is recommended that you bring a representative sample to check the entire RIP process. See how long it takes for your chosen RIP to RIP and print the files you have brought, how long it takes to re-print multiple copies of files...

2. Color conversion

In the desktop publishing system, most of the images used for processing are scanned by the scanner to the inside of the computer, and the colors of the images are displayed in the RGB color space when they are displayed on the display of the computer. When printing, the colors of the images are all converted in the CMYK color space. If your workflow requires your RIP to make color transitions, then you must test this aspect of functionality when selecting RIP. For the output of high-grade fine prints, your choice of RIP must have a good user interface so that a skilled operator can adjust the color transitions between image processing and image output.

3. Color Management System

The color management system is to enable the color between different devices to achieve or correct the color between different devices, so that the color output between different devices to correct, so that the color output between different devices Match the color you need as much as possible. In order to enable RIP to support color management, it is required that the RIP must be able to accept the color characterization table of the working standard color profile. At the same time, the RIP must also allow users to have yellow (Y), magenta (M), blue (C), and black (K) Four-color version of the level curve to adjust. Ideally, RIP thick can adjust the level curve after the RIP of the image. This helps the user to make final changes to the output result on the final output so that the user does not need to return to RIP before image processing. In the process to make changes.

4. Storage capacity

Because the RIP of graphic information is a step after printing, and because the processing of the image takes a lot of time, the file capacity after RIP storage is a vital function of RIP. If there is a problem with the printer or the file after RIP must be reprinted, files with large storage capacity after RIP, and RIP with large storage capacity are the most efficient and quickest way to reprint files after RIP. This also means that RIP needs a large storage space to store the file data after RIP, and also needs a good user interface so that the user can quickly select and reprint the files after the RIP.

5. Statistical record function

In local area and wide area networks, there are many users sharing a color output device. At this time, RIP plays a role as a control center in the network. It can automatically record every file it accepts. It also records the number of pages generated for each file. Therefore, powerful statistical functions can help network managers or print managers track the situation of the department or financial center.

The cost of RIP

In the entire digital printer, RIP costs about 50%-100% of the entire cost. Because RIP determines the application scope of the entire device, it is worthwhile to purchase a good RIP.

However, one thing to keep in mind is that RIP technology is developing rapidly. It is usually updated every 9 months or every 12 months. Therefore, the best decision is to plan ahead. As a matter of principle, when purchasing RIP, not only can you meet the needs of South Africa now, but also make it easier for your RIP to be able to postpone the time due to RIP, then you may be able to purchase newer products.

In short, anyway, the development trend of RIP technology is an important condition for you to choose RIP correctly. At present, more and more developers are committed to the development of software RIP, because software RIP is more suitable for the development of the computer market.
