The mid 1990 s, digital proofing in domestic has just started. At that time, including output devices, and color management software, all sorts of relevant technology are not mature of digital pulls the common people becoming ambivalent. However, make the industry, especially the traditional proofing equipment manufacturers of unexpected is just a few short years, digital proofing already began full before printing market segmentation proofing "cake" traditional printer manufacturers have to stop the traditional proofing equipment manufacturing, completely out of the market. Digital printing, especially digital proofing become domestic before printing trends, such as in the field of arrows, and then what.
Data control superiority
1, use cost
First is the cost of buying equipment. To purchase a set of traditional proofing equipment, in addition to provide and the related bask version, and the print the equipment, skilled workers and a large scale of factory building is also essential. And at present market a high-end inkjet digital proofing equipment, with professional color management software. Its placement cost according to need in 20000 ~ 70000 different wide between yuan. Second, pulls the ultimate goal is to obtain satisfactory results can finally added to the printing and printing processes a. If take traditional proofing and digital proofing, the latter than more shows unique technological advantages. Traditional proofing process complex, and a formal agreement to printing processes, it must first film, to PA version output after the sun beat prototype output tear sheets, once the sample and the needs of the customers when not easy to start again, often can cause more waste materials.
2, the production efficiency
As the name suggests, is a unit of time than the production of benefits. The speed at sampling, compared the digital leaflet print the time needed is basically for 50% of traditional proofing, and the result is more obvious. If the idea, plate burning, printing need time ignored, just pull the traditional characteristic menu type proofing action, leaflet print need an average 30 to 40 minutes. And now in the market a side from the printer, printing speed precision sheet can be controlled in 20 minutes less than.
3, quality comparison
Traditional proofing mode of operation is half manual, output in the amount of ink sample for the control and colour, grasp depends to a great extent on the level of experience and proofing workers. Also is so, traditional play out the sample of the prototype effect is very unstable. According to insiders, the introduction of in the past by traditional proofing, the same set of film take out respectively pull, gain the effect usually is not the same. Digital printing and imaging, because it's so the traditional automation proofing is more stable. Of course, here need to exclude some uncertain factors, such as the print head is stable, whether to need change, or because the frequency forging use not original cause printer ink the phenomenon such as this.
Technical innovation is our scouts who incoming fire has
1, work to do a good job, you will have to have the benefit its device
Digital output equipment and color management software, can saying is the key of digital proofing. How to give full play to the advantages of digital proofing, hardware equipment manufacturers have broad shoulders. In recent years, digital output manufacturers expectations, to break through the bottleneck system technology, whether the printer, or hardware performance color management system, all have improved significantly. To mainstream manufacturers Epson, for example, the research and development of the new through high-tech, launched one of mainly used in commercial printing before printing in the field of digital proofing and high-end image output of the field a printer Epson Stylus Pro 9800 face in colour, the printing speed, reducing imaging stability to have new breakthrough.
2, the stability and the color of the consistency of the reduction
Epson Stylus Pro 9800 eight of the application of color "century rainbow" pigment ink new erp, the "light black", to print ink color accuracy, whether in the image or in detail level, burnish were promotion of the quality. Overall upgrade of gray balance print effect, to eliminate the color distortion, the color transition levels than before a more natural surface of the printer. Epson unique micro piezoelectric and print technology precise control the size of the ink drops in the maximum resolution up to 2880 x 1440 dpi, also can achieve the minimum drops 3.5 slightly litres of excellent print precision and effectively ensure the prints and prints of the sample between color consistency. In inkjet process, the print head need not heating process, so the chemical composition of the ink didn't change, make a single nozzle at work to keep high frequency stability.
3, speed improvement and cost control
A Pro9800 inch wide the print head than the last generation product doubled print nozzle to each color 180, totaling 1440 a nozzle. Increase the print head every time move the printing area, a print a new face rapid standards. In ascension, and at the same time, use the speed motor drive system of high accuracy and position detection system, micro piezoelectric printing technology more precise control inkjet ink drop size, flight direction, avoid incidental residual ink drops. Minimum drops even reached 3.5 rise slightly, the print head and paper every displacement are accurate records, every detail can be accurate performance. Long life design micro piezoelectric the print head, normal use without replacement, save the print head expensive replacement cost, also avoided for repeated the print head calibration and time consuming fee mo.
