With digital proofing equipment, the first response from more people is the Epson large-format inkjet printer using inkjet technology. Indeed, Epson's wide-format inkjet printers are comparable to high-quality prints with their precise print accuracy and accurate color reproduction accuracy, bringing new life to proofing applications and creating new applications in the proofing industry. In the following years, some other manufacturers also launched similar devices and provided relatively complete solutions. So, how to pick a solution that suits you is as early as it could not be compared with the simple parameters from the basic equipment in the past. Facing the high printing accuracy and ink color quantity that each manufacturer claims, as well as the promotion of the selling points of various manufacturers, there should be a pair of eye-catching eyes to see the flowers in the fog and the moon in the water.
Accurate color reproduction is the key
In the field of printing and proofing, the most widely used is commercial contract proofing. As it is the only color assessment standard and multi-authorized legal basis from the graphic design to the printing process, it is required to achieve accurate color reproduction, and the color deviation value (â–³E) has become an effective touchstone to evaluate the color reproduction accuracy. . The Epson Stylus Pro 11880C representative of the five Epson digital proofing device color deviation has been controlled within â–³E <1, the error is far below the industry recognized (â–³ E <3) standard. At the same time, the outstanding color stability of the "Epson Century Iris K3VM" pigment ink enables users to perform ICC curve creation and other operations after half an hour of image output. The smallest color deviation and the fastest color stability make Epson's leading position in the field of digital proofing.
Even in the face of the application of more spot colors in the field of packaging and proofing, Epson can easily respond. Taking the “Century Iris K3 VM†pigment ink as an example, through the addition of a magenta ink with a higher color density, the company has become the only company in the industry that can accurately restore “Bobby Doll†powder and “Pepsi Cola†while achieving full-scale image color optimization. Blue and other difficult color manufacturers. In addition, Epson's black print output can reach a maximum density of 2.41, which means that its output image can achieve a greater range of light and dark, restore more levels and details, giving a strong visual impact. "Seal - push (spur) - receive" high-quality output print head each time the accuracy of the ink droplets to determine whether to obtain high-quality print works. Observing the ink-jet print manuscript under the magnifying glass, it can be found that the image is composed of colored ink dots. In the manuscript printed using micro-piezoelectric technology, the ink droplet size is uniform in three sizes: large/medium/small, and there is no splash around the ink drop. The smaller satellite drops come out. This should benefit from the three classic workflows of “micro-piezoelectric†“push-push (buffer)-receiveâ€. The piezo crystal is controlled by the electric pulse signal, and the corresponding ink volume is formed to eject the corresponding volume of ink droplets from the nozzle. , And in the last part, the ink droplets on the surface of the nozzle are “flyed†before they fly out of the nozzle, ensuring that the ink droplets flow smoothly after flying out of the nozzle, and no large ink droplets are split into several small ones. Drops of ink hit the surface of the media. Avoids the "vignetting" phenomenon caused by ink droplets, which is the weakness of other inkjet technologies. In the field of digital proofing, the feature of post-RIP proofing is that you can check the accuracy of the screen and the accuracy of the screen, whether it hits the net, etc. If there is a circle of “vignetting†around each dot, the result will directly affect the accuracy of the proof after the RIP. Of course, this phenomenon does not have much effect on the pattern proofing/newspaper proofing/infrared modulation proofing below 150 lines, but it seems to be awkward for the ever-increasing print quality.
Intelligent ink drop conversion technology completely eliminates horizontal stripes
In digital proofing applications, users want to be able to restore precise printed dots, including dot size, dot angle, dot shape, etc., to achieve post-RIP proofing. Undoubtedly, finer ink droplets can restore dot shape more accurately, but everything has advantages and disadvantages: If only fine ink droplets are used, multiple prints must be performed at the same position in order to eliminate gaps between droplets. The method not only reduces the printing efficiency, but also tends to appear horizontal stripes when printing solid background images. This type of fringe does not have much of an impact on printing color-rich video productions, but it is fatal in digital profiling applications.
Why is it easier to create horizontal stripes when printing with a single size ink droplet? This is not only related to the printer, but also has an inevitable correlation with the error in the longitudinal travel accuracy. The printing accuracy is divided into horizontal and vertical precision, and the lateral accuracy is the accuracy of the print head's moving direction. Because accurate raster detection technology is used to detect the position at any time and place, and one-way printing can also be selected, the lateral accuracy is guaranteed; However, the longitudinal paper-feeding accuracy is not easy to control. The operation of the printer's motor and drive system, and even the thinness of the media, will affect the longitudinal paper-feeding accuracy. If you are using smart drop conversion technology, this problem can be solved. Thanks to Epson's unique intelligent ink drop conversion technology, three large, medium, and small ink droplets of different sizes can be ejected each time the print head moves according to the characteristics of the graphic image. When these three types of ink droplets are ejected simultaneously as needed, the inter-line ink droplet voids generated due to the error in the paper-feeding accuracy can be covered by the larger ink droplets, thereby avoiding the generation of lateral stripes in the solid background area. This is why when a single-volume ink drop printing scheme is used, hard and soft detections always appear to work but stripes still appear.
Of course, there are many factors that determine the quality of digital samples. The choice of RIP software is also very important. Due to the differences in the color management engines of different RIP softwares, the interpretation of the same design manuscript may have different color performance; for example, digital proofing media Matchingness also needs repeated testing to be confirmed; integrated production efficiency is also a key point that should be concerned.
Think about it being a steady step, a step-by-step work, or an efficient output of defective products, and then carry out a complicated proofreading adjustment output, and after a while, it will output defective products again. Which is better, presumably the user will have their own choice.
