At the end of 2016, the paper price hike unexpectedly encountered the electronic supervision code , which caused countless people in the industry to panic and pressure. I believe that everyone has been impressed and remembered, and truly interprets the new era of "Luoyang Paper" Shanghai Electric . Let the original suffering from artificial increase, shrinking orders, environmental pressure and other factors The development of the printing industry is worse. When it is, the cost savings of paper is undoubtedly a major issue that all types of printing companies must face. Publishing dynamics
It is undeniable that frequent revisions are still an important reason why many printing companies waste paper today, and they are also a hindrance to hinder enterprises to reduce costs, improve efficiency and competitiveness. Management
Frequent revisions, the reason label , or the digital requirements of high-end overseas customers, or respond to customer-like proofs, or respond to reprints and color reproduction. Under these circumstances, many printing companies often need to repeatedly re-edit the machine to reluctantly achieve, as little as one or two equipment operations , more than three or four times, and some difficult work orders even more than ten times. A printing machine can only be used for frequent trial printing for a long time or a whole day, and the production orders cannot be printed at all, let alone the loss of equipment, paper, ink and labor. Now that the printing industry has entered the era of meager profit in the Red Sea, the owner of the printing factory naturally looks at the packaging logistics in the eyes, and is eager to know how to minimize the revision caused by bad color, which has become an important issue to be solved urgently. unemployment
Based on the understanding of the actual situation of the visiting printing plant, this paper focuses on the analysis and demonstration of the following situations, and gives the suggested solution: lithography
No proof l - ordinary developing digital proofing
This type of factory is mostly a printing company that accepts processing orders. In the past, it only focused on order processing and proofing . Investment printing machines began to print, and the pre-press is relatively weak. Even many companies are outsourcing and publishing. Generally only blue paper proofing (layout), no digital proofing (color), only know the depth of Konica Minolta on the machine, encounter high-end job and color requirements, due to the lack of accurate predictability, the printing effect on the machine often Hard to be willing. This is like a gamble: If you are lucky, you can follow the color by adding or subtracting the ink; however, if you are unfortunate, the PS version will be inevitable. Cutting
The recommended solution for this type of customer is the digital proofing system on the prepress. The more mature configuration in the market is the EPSON large format proofing machine + CGS/GMG/EFI system + automated color measuring instrument, and EPSON is currently based on the SureColor series. P9080/P7080 (11 colors) or P8080/6080 (nine colors) dominate, which will lead to the update of the software system to support the new printer version, such as CGS Color Tuner Web 3.2/GMG Color Proof 5.9/EFI ColorProof 6.4 and other Konica Minolta , some companies need to print 1-bit-tiff color separation files, also need to increase the Screen Dot dot proofing module. This digital proofing system is generally based on original paper and original ink, and is accurately calculated by software 4D module cycle. After adjustment by professional engineers, it can be proofed by precise automated measuring instruments (such as Xrite isis EFI , i1iO, etc.). The average color difference with printing is controlled at around 1, and the maximum is around 3, which conforms to the ISO12647-7 standard. This is the most stable proofing system that is widely accepted and widely used by the market. Offset printing machine
Imagine if you implement the same matching digital proofing and color printing, a proofer is equivalent to one or several printing presses integration, the final printed colors do not need to be published in the front, through digital proofing can easily predictable, compared to up to On the machine printing, it was found that the color could not be adjusted and the situation needed to be adjusted was less detours, the efficiency was greatly improved, and the cost was much less. Therefore, at present, the prepress department of the general medium and large-scale printing enterprises is equipped with at least one such system. Proofing
l got ordinary digital proofing - or on the packaging or special digital proofing Han Guanhua
Ordinary digital proofing is an imposition for general books and magazines. Because of its common copper plate, matte powder, light coating and book paper, it can basically simulate the printing color correctly. However, for packaging companies, due to the special nature of the printing materials, such as gold and silver cards, film, dust, white cards, etc., there will be obvious limitations. In this case, printing companies generally have the following different options: flexible packaging
