I now have a question about how to choose between digital proofing and traditional proofing?

In the global digital development, computer to plate (CTP), CIP3, CIP4 adoption, the implementation of the print shop color control system and other digital technology, so that the entire printing industry to improve the digital process needs to increase to replace the existing traditional production methods. The digital process involves a very wide range of digital proofing, which is the most popular concern. The industry from the beginning of the implementation of digital proofing conditions of the harsh, to the maturity of today's technology and most of the printing enterprises to adopt. Mainly by the following factors at play: the improvement of equipment accuracy, digital proofing system stability is not a problem; but the factors affecting digital proofing are many, until now, digital proofing is still being explored and continue to improve the necessary. ◆ Digital proofing machine's fine and ink system and proofing paper? ◆ The color correction method of proofing software and the corresponding limit of color gamut? ◆ Evaluation focus: correct interpretation, color, neutral gray, resolution? ◆ Measuring instruments and color management software? ◆ Color knowledge background and calibration capability of prepress system manufacturers? ◆ Observation environment and conditions? ◆ Printing machine characteristics and ink color gamut? ◆What are the standard colors? ◆What are the standard colors? ◆What are the international standards? The above questions should be some of the problems encountered by the general industry. When doing digital proofing, the printer is a prerequisite, if the printer is not good, in the color management, because the conditions exist to change the effect is not ideal, affecting the accuracy of color reproduction, so choose a good printer. Good printing company launched two multi-media digital proofing system, based on epson high-precision printout platform, after years of technological innovation and accumulation, expanding the original equipment can not realize the function. Provide perfect and rich cross-industry solutions to assist the printing factory to connect the printing process automation standard operation, as CTP pre-press proofing excellent supporting, its multi-media output function and good matching, has been recognized by more and more CTP users and widely used. And the choice of ink is not quite the same, for example, like when we play spot color, ink should be different from the past, different industries in the use of ink is selective, part of the spot color beyond the color gamut part of the printer can not print, the only way is to change the ink. Good Impression Digital Technology Co., Ltd. and Wuhan University "Packaging and Printing Engineering Department of the" production, learning and research "cooperation, after three years at a cost of more than 3 million, successfully developed" with e print "imitation printing special ink, access to the National patent certification. The first to introduce printing ink to the core platform of inkjet printing, color gamut and printing color gamut seamless match. After a number of technological innovations, 100 ℅ imported raw materials, ink production process has strict quality control. The product is environmentally friendly, non-toxic, light, high resolution printing, wide color gamut, and has a strong waterproof, scratch-resistant performance. Its physical and chemical parameters have reached international advanced standards. Thus ensuring that the print is clear and colorful. Random Printing Series ink is a salt-free formula and pH near neutral, with the role of preventing nozzle crystallization and clogging, which is beneficial to extend the life of the ink head. Printing process can keep the printhead clean, with the best drying time, maximize the efficiency and stability of printing. Then there is the use of paper, we have been talking about the paper affects the color of the printed product, if the paper color and the official color of the printed product there are large differences in the digital proofing effect will be greatly reduced, based on this Xiamen Good Impression Digital Technology Co., Ltd. can be developed in the printed material on the sampling technology, once the launch of the positive feedback, so there are three key points to be had under this premise, a high-quality printer Good ink system and printing to match the proofing paper. Proofing color calibration software and the way the color core, CMM can do a perfect conversion, the image details of the part of the color is very important to the non-collection point of the color control is also very important, because the ICC characteristics of the file is not possible to map each color to the equipment does not relate to the color gamut space, the CMM calculation method and accuracy in the output of the calculation process plays a fairly important role, Xiamen good impression! Digital Technology Co., Ltd. uses today's most accurate RIP software, so that digital proofing and color gamut of the conversion limit, with the use of paper has a relationship with the coated paper to play a better effect, with the molded paper to play it out it is not good, with a very good paper to simulate the poorer color gamut, in fact, it can be done. Then is the correctness of the RIP, color, dot shape, resolution, to the current point of view of the digital sample can do the above points, made with the printed dot very close. The degree of accuracy of the instrument and color management calculation method, the previous color management has not been done well, because the technology is not mature, color management software calculation method is not precise enough, so with good software algorithm, the result is more accurate. Good impression and Apple color management application experts jointly formed a color management R & D management center, the introduction of foreign advanced RIP color management technology, simulation production ICC color curves, color simulation fully in line with European color standards. Has been tailored for a number of domestic top 100 printing plant pre-press color standards, so that the pre-press proofing effect is fully comparable to the prints, the effect of color follow-up to more than 95%, by the customer's recognition and favor, to provide a variety of industry needs suitable for the color management of the digital full-process solutions, whether it is a multi-media printing, or professional technical support of the color management, you can get a full range of professional and meticulous services provided. Observation environment, usually when doing color calibration, the observation environment is very important, because it is difficult to match the color when viewed under a non-standard light source. If two colors have different spectral distributions (spectral reflectance curve, or spectral transmittance curve. This curve can be measured by a spectrometer), when in a particular lighting and observation conditions, the two colors will look the same, if the lighting and observation conditions are changed, the two colors will not have the same value of the three stimulus to make the color look different, this phenomenon is known as the condition of equal color phenomenon, or the phenomenon of the same color isotropy. Different printers use different presses and inks and different master printers will produce different results, which is the most difficult problem to improve. Reference address: www.xm1000.net
