Digital proofing: Print your tomorrow

Large Format Printer - HP DJ5000ps

People often say short and short, but now we need to re-examine this point of view. It is as if the digital printing industry is a good example now:

Hewlett-Packard, with its vast experience and technology in the printing industry, provides the printing industry with complete digital proofing solutions. The program uses Hewlett-Packard’s high-quality HP DesignJet 5000PS as a printout, and Rainbow Dijet uses internationally advanced color testing tools and proofing RIP. After two years of experimentation and exploration, it combines more than ten years of experience in traditional plate making and proofing. , Innovation introduced a digital proofing color management data curve suitable for domestic printing conditions.

With such a large printer, will there be problems with large format printing?

I believe that after you read this article, those questions will disappear quickly.
As a successful work, there are many steps to complete before it succeeds.
First of all, we must put a good idea on the design work computer and proofread by typesetting. Transfer to RIP RIP print server via LAN or Ethernet. After a specific RIP can first see the color sample on the computer. Although this is just a screen effect after RIP. But it can make people find some problems found in the proofreading. Once there is an error, go back to the design work computer to modify it. After the change, it is transmitted to the RIP RIP print server through LAN or Ethernet. After no error is found, it is transmitted to the digital printing station through the network cable. The RIP interpretation file was used on a printing computer, and the printability (A) curve developed in cooperation with Hewlett-Packard and Rainbow Dijet was used. It was printed on an HP DesignJet 5000PS six-color inkjet printer. If there is an error return the design work on the computer to modify. After the change, continue the previous steps until correct. We got the final standard printed proofs. We can also find errors that were not found during layout and on the screen from the proofs. The timely discovery of these errors helps designers and companies to control costs and have more room for profit.

(A) Printability: It refers to the speed, humidity, humidity, ink volume, and the surrounding environment of the proofer.

The HP DesignJet 5000PS printer takes full account of the need for digital proofing in quality and speed.
HP DesignJet 5000PS in terms of speed, due to the use of more advanced Jet Express technology, the number of nozzles on each print head as much as 512, coupled with a 25mm wide print head, high frequency jet up to the maximum per second jet 15,000 dots, each line can print a width of 20 mm. With the support of new technologies, the HP DesignJet 5000PS print speed has been greatly improved, without the drawbacks of past inkjet printing speeds. It is currently the most professional large format printer. Its 152cm model can reach a maximum speed of 52.86 m2/hour, the best quality print can reach 7.08 m2/hour; the maximum print speed of the 107cm model can reach 40.36 m2/hour, and the best quality print speed is 6.32 m2/hour. In other words, at full-format best-quality prints, 4.6-5.9 m long can be printed per hour, approximately 7-10 pairs. This speed is already much higher than the overall speed that traditional proofing can achieve. In terms of color, this series of printers uses six-color ink and color grading technology, which allows up to 21 ink dots to be ejected in the same position, increasing the number of layers per ink dot, and improving the fineness and level of printed images. Sense, to achieve a truly practical six-color ink printing and 1200dpi printing. Consumables are equipped with smart chips that not only guarantee print quality but also make the cartridge longer.
Moreover, the HP DesignJet 5000PS large format printer is equipped with a temperature and humidity sensor. When the temperature and humidity changes, it can be automatically adjusted and the quality of digital proofing can be kept stable. Once the proofing and coloring file (ICC file) is determined, the proof color of each figure is determined because it adopts a closed-loop color calibration system, which can ensure that the same proofing is output multiple times and the proofing quality is unchanged. This is also a prerequisite for remote proofing in the future.
In terms of proofing costs, compared with traditional proofing, four proofs and eight open proofs are taken as examples. Traditional proofing requires 200-300 yuan (only the cost of paper and ink, excluding machine depreciation), and “HP Digital Proofing System” The cost of a proof sheet is about 30 yuan, and four sheets are about 120 yuan. Even if the sample is modified during the proofing process, because the digital proofing is now proofing, after the film, so once the proofing effect can not meet the customer's requirements, the plate making company only needs to proof again, until the customer satisfaction, signature confirmation, without repeated Out of the film, avoid unnecessary waste, reduce the cost of modification.

In the past, printers using a small format usually only printed a single page layout, but could not verify the effect of the output printing plate. A true digital proofing system should have a print format that is consistent with the printing press so that it can fully simulate the effects of traditional proofing. The HP DesignJet 5000PS features exclusive layouts and folds. Used to check the effect of the layout.

With these advantages, you will be able to involve more areas in your future business. It is believed that the speed and high quality of the HP DesignJet 5000PS will enable those individuals or companies that choose the HP DesignJet 5000PS to have a superior grasp and strength in the fierce market competition.
