The new proofing model that came into being--The clever combination of HP5000 and HP10PS

One: The dialogue between printers and customers The printing industry is changing with each passing day. With the continuous popularization and development of CTP technology and all-digital processes, digital proofing as a new technology is being accepted by more and more printers and customers. The equipment, solutions, and color management software have come one after another. The competition among manufacturers has become increasingly fierce, and digital proofing has become more and more intense..... However, when this “digital” trend became a necessity, digital proofing gradually exposed some Shortcomings and weaknesses, such as: China's printing industry is not unique to printability, lack of uniform standards for digital proofing equipment, color instability between various printing equipment, can not achieve true color management; digital proofing management software Matching with printers, photo-composing machines and other ancillary equipment is not enough; some printing companies cannot make good use of digital proofing, mistakes and errors, and it is difficult for print products to catch up with proofs. Not only can they not really shorten the cycle and reduce costs, but they can attract customers. Repeated complaints.
Let's listen to the customer's complaints and the voice of the printer:
The customer complained: “Usually, we send the produced electronic file to the color printing factory or the export center for digital proofing. Sometimes it goes smoothly without any errors. After the proofs are signed, we can make plates and print; but there are often unexpected mistakes. At this time, they had to return the documents to us for revision, and then take them back to re-proof the sample..... This model was time-consuming and laborious. It was often due to one or two small mistakes that caused them to go back and forth a few times or even a dozen or so. It was difficult to satisfy us. Aging requirements lead to longer production cycles and higher production costs....How can we minimize the incidence of errors? In order to do more with less?”
The printer’s helplessness: “In fact, we also feel a headache and helplessness in the mistakes of the proofing process. Not all errors are caused by us because some errors are hidden in the customer’s electronic files. In addition, when we get After the digital proofs, some customers were dissatisfied with certain elements, layouts or colors of the proofs, and felt that they were different from their own ideas. At that time, they requested to modify the electronic documents. The round trip extended the cycle, the sample modification process was cumbersome, and the number of Cost, affecting normal production arrangements, must also bear the customer's continuous complaints.....
In general, a large-format proofs would be more expensive, and the cost would naturally not be low. The customers would find it difficult to bear. We feel very grieved and frustrated. We also hope to find an effective solution to this problem. ”

II. Prospects for Digital Proofing Technology From the technical forecast report of the American Printing Technology Foundation (GAFT) in 2002, we can see that in the next few years, the printing industry has put forward new requirements for digital proofing technology. These new requirements It coincides with the current lack of digital proofing, which is reflected in color management, remote proofing, shortening the production cycle, and providing value-added services. Here we will look at the trends of digital proofing by quoting the predictions of experts from some giant companies in the industry:
1) Enhanced color management The core technology of digital proofing is reflected in the application of color management. The quality of color management directly determines the success of digital proofing.
Larry Warter, director of the Fujifilm Corporation in the United States, said: "The proofing technology in the printing industry is at a watershed stage. As an industry, we are transitioning from the "match" phase of the same density and dot gain values ​​to the color Labs absolute. Value, thus opening the door for future proofing technology development."

2) Promotion and popularization of remote proofing From the above dialogue between customers and printers, we can see the practical significance of remote technology for digital proofing. If remote proofing technology is available, the color printing factory or the output center can directly proofread the electronic documents of the customer at the other end, which eliminates the fatigue of the customer's back and forth travel, thereby increasing the production efficiency and shortening the production cycle.
AGT/Seven’s Ed Saturn commented on remote proofing: “Many of my clients are looking for a web-based digital workflow. Using it, a work created in New York can be disseminated globally in a reliable and easy manner. ."
3) Providing value-added services, shortening the production cycle, and strengthening customer relationships Whether it is a printer or a customer, it has always emphasized the production cycle. Because for them, the length of the production cycle directly determines the timeliness of a job, but also seriously affect the level of production efficiency and cost. How to strengthen the relationship with customers through value-added services; how can we shorten the production cycle as much as possible so as to increase production efficiency, enable a win-win situation between printers and customers, and maintain a good and stable cooperation relationship? ....... These issues have been tied up with printers, and their solution may be the key success point for each printing company to stand out.

Three: A new generation of proofing mode came into being - the ingenious combination of HP5000 and HP10PS From the above text, we can see whether it is the customer's complaint in the actual production or the printer's voice, or digital proofing The future development of the company puts forward new requirements and challenges for the existing digital proofing model. From the perspective of long-term development, the transformation of the proofing model is imperative.
As a pioneer in the field of proofing in the printing industry, HP is unanimously committed to helping printers and customers solve various problems, and is brave enough to create new ideas and innovations. In response to the current status of digital proofing and its future development trend, HP has launched a new generation of proofing models ------HP5000 and HP10PS with the use of rainbow color technology and Didi's color management system. This new model not only satisfies the strict requirements for color management in the proofing technology, but also shows the advantages of digital proofing in terms of speed and color through the ingenious combination of the two devices.
1) HP5000
We know that the HP5000 has always been the preferred device for many output centers and inkjet shops, and it has an absolute advantage over print quality and speed.
The HP DesignJet 5000 uses HP's smart printing technology, which includes smart color technology, which is also known as the third-generation "Furtu" color layering technology. Smart color technology allows each primary color to print out 17 different levels of color intensity. These colors can be mutually reconciled to increase the color of the printer palette by 100 times, and to achieve 1200×2400 dpi printing accuracy. Since smart color technology can control the amount of ink of each color ink in each printing position, it can make the color range wider and the transition between colors smoother, which can significantly improve the print quality.
Also attracting buyers is the print speed of the HP DesignJet 5000. The stable and high-speed printing speed is not only a reliable guarantee of production efficiency, but also an effective way to win customers' trust and win customers. The HP DesignJet 5000's print speed benefits from the intelligent Jetexpress technology, which is another important technology in HP's intelligent printing technology. The technology uses a wider print head and increases the number of nozzles on the print head to increase print speed and print quality. The greater the number of nozzles, the faster the printing speed. Printers that use intelligent jetexpress technology typically have 4 to 6 print heads, each with 512 nozzles. The hp designjet 5000 series with its 6-color print head features 3072 nozzles, which increase the printhead's inkjet frequency to 15,000hz and print speeds of 4 to 6 times or more.
2) HP DesignJet 10PS
In this printer, there are six ink cartridges installed, the original cyan, magenta, yellow and black, as well as the new bright cyan and bright magenta, the cartridge ink is based on dye, which includes black, can print real black , guarantee the printing effect of offset printing.
In the same printer, the speed of the HP DesignJet 10 PS is impressive. Printing at 600 x 600 dpi resolution takes 6.55 minutes; printing at 1200 x 600 dpi resolution takes 14.30 minutes. This is obviously less time than similar products. In terms of print quality, at 600 × 600 dpi resolution, text edges less than 8 pt have some glitches; at 1200 × 600 dpi resolution, all text, including 5 pt size, print quality is perfect. With regard to cost, HP DesignJet 10PS printers have 20-30% full-color ink coverage (images) with excellent quality and maximum resolution, according to HP's consumption assessment. However, the ink and paper used are very economical, and the overall application cost is very low.
In addition, the HP DesignJet 10/20PS continues the popular open-edition style of HP's previous printers - the DesignJet 800PS-107 cm, the DesignJet 1055CM-91 cm, and the "mega" and multifunction printer DesignJet 5000 PS with 152 cm print Width and extra proof capacity are printed even on newsprint media.

3) Rainbow Dijet Color Management System Rainbow Color Management System CMS developed by Beijing Rainbow Dijet Digital Technology Co., Ltd. uses ICC standards to manage the color space of different devices in the workflow. It consists of three parts: First, the equipment The unrelated CIE reference color space; the second is the device's ICC profile (PROFILE); the third is the color management module CMM. Among them, the color management module CMM is the core, it is the use of professional digital proofing software combined with other color management software, fine-tuned color space conversion data integration. These data centered on the commonly used printed materials and processes in the country, and made a lot of in-depth color space model experiments under different production conditions to simulate the printing and proofing results and measured, so the data is accurate and comprehensive, and it is truly suitable for China's national conditions.” Digital proofing is a good helper.

There are already enough promotions on the HP5000 and HP10PS in the market. We don't stress too much here. We mainly want to promote a new digital proofing model, which caters to the development trend of digital proofing and can help printers and customers solve their current difficulties.
For a printer or output center that already has an HP5000, it is a good idea to configure a cheap and practical HP10PS. With accurate color reproduction, high quality print quality, impeccable print speed, and a wide range of sizes, it can work in harmony with the HP5000 to create a new proofing mode. In addition, when the operator is first proofing for a print job, if there are more uncertain factors or only a layout proofing, HP10PS can be selected for small-format proofing, and the customer is satisfied with all elements and layouts on the layout. After the final contract proofing. The benefits of this are: speed, low modification costs, accurate color, and flexible operation.
On the other hand, printing companies can configure a HP10PS printer for long-term fixed customers. Using Rainbow Dijon's color management system, HP's digital workflow proofing portfolio can be easily implemented. The customer can easily achieve a small amount of proofing within the A3 format in his office space, and immediately correct the errors appearing in the proofs until they are satisfied. Then the electronic documents are delivered to the printing factory. In this way, it is easy to solve the dilemma of repeated modifications and round-trips in the past. The production cycle is shortened and the efficiency is improved. Moreover, deploying a cheap printer for long-term customers may be a trick for printers to provide value-added services, strengthen relationships with customers, and win surprises.
