Digital printing is actually a value-added concept. From the perspective of short-run printing alone, it can be seen that its potential is infinite. With the advancement of technology, anti-counterfeiting printing is only a part of Yunyun's benefit.
Highly anti-counterfeiting and commercial printing have always been separate and independent. The purpose of this article is to discuss the benefits of security printing on the commercial digital printing industry and the impact of the latter on the former.
Up to now, the main industrial use of digital printing is to print labels for short-run pharmaceuticals, consumer products and other packaging products. As brand owners are increasingly concerned about the losses caused by the appearance of counterfeit products, but are reluctant to purchase devices such as printable holograms, this will undoubtedly bring valuable business opportunities for digital printing to provide low cost such as personalization Brand protection such as anti-counterfeiting design.
In the next few years, several innovations in the digital printing industry are expected. This phenomenon reflects the increasing demand of the digital printing industry. For example, Swiss CanPet AG invented the first digital printing device Printomat 400 to print cylindrical prints, making it possible to print directly on beverage cans.
In addition to increasing the potential of unique anti-counterfeiting features, digital printing brings other benefits to brand owners and packagers, including: lower cost, less product and inventory, faster time to market, and the ability to print variable data pricing Or instructions, more potential to cope with short-term product replacement, less loss and shorter supply chain. For brand owners who intend to add anti-counterfeiting features to their products, digital printing that combines all the benefits is the most appropriate.
Anti-counterfeit printing
Digital printing provides multiple solutions to combat counterfeit products. Losses caused by counterfeit products have become the most important and important thing for brand owners. Digital printing allows users to use anti-counterfeiting inks and materials, and can achieve personalized packaging design.
The above examples are obvious. For example, digital inkjet printing creates a new field for packaging printers, including: printing unique prints, providing corresponding services in response to individual customer requirements, product innovation and anti-counterfeiting. In fact, counterfeit products are a problem that cannot be ignored, and even become an important consideration in the entire production and product distribution supply chain. Now, innovative and improved technology can be applied to the entire production process. This shows that the combination of anti-counterfeiting printing and digital printing will be the development direction that printers are looking for in the future.
Cambridge University Examination Board (UCLES)
UCLES is one of the famous organizations, specializing in the production of test papers and other supporting materials to realize the above ideas in the UK and international markets.
Cambridge Printing Department and UCLES worked together in Cambridge, England in 1999 to practice anti-counterfeiting and the application of cutting-edge digital printing technology. At present, they provide test papers and other supporting materials for a quarter of the UK and overseas markets.
Based on the requirements of test papers and auxiliary materials, the anti-counterfeiting and zero-error production process is the most important. If the printed test paper is wrong, or if the security measures are insufficient before it is officially issued, the consequences will be difficult to estimate. In addition to meeting the necessary conditions listed above, flexible handling and on-time delivery are also extremely important during the printing process.
The above-mentioned prerequisites have prompted UCLES to invest in a complete digital production system, and cooperated with IBM to establish a set of specially designed programs with the goal of establishing a unique printing production model.
Cambridge Printing and UCLES continue to work together to improve the strict security of the digital printing process, and have also developed tailor-made processes, including online tracking and electronic procurement.
Digital printing can combat piracy
Recently, the American Film Association (MPAA) banned the delivery of films on DVD before the awards ceremony. The main reason is that the relevant departments believe that most of the pirated films come from this source.
But technical solutions, including the successful development of digital printing, have solved the problem.
At the 2004 Academy Awards Ceremony, Technicolor used brand-new security technology to produce special films for specific film production clients and independent film distributors.
This technology uses a watermark that can be tracked in forensic medicine to write independent and continuous codes into VHS video or DVD video content. The watermark is hardly visible to the naked eye, and can help video copyright holders and distributors to identify attempted pirates of the film. According to a Technicolor spokesperson, the technology has successfully tracked a video distributed online, arrested and charged a member of a pirated group.
To ensure the safety of the film during the European Movie Art and Techniques Academy Award, Technicolor specially created the Flexplay DVD film, which is characterized by the fact that it cannot be opened 48 hours after the package is opened.
Flexplay actually only provides short-term solutions to long-term problems, but digital printing can provide longer-term solutions.
Secure Media and Action Duplication recently purchased digital printing equipment, and their product coding and piracy protection functions are ideal. Action Duplication is a company engaged in replication products, and Secure Media is a DRM encoding supplier.
Digital printing equipment has many advantages, including improving the quality of digital pictures. At the same time, the copying equipment can also independently print consecutively arranged codes on each computer disk for tracking and identification.
The device first prints the image on a special transfer film, and then coats with a layer of tackifier. After being rolled by a reel that generates heat, the image will be transferred from the transfer film to the magnetic disk. The reel releases the dry toner on the transfer film at the same time, and adheres the tackifier and dry toner to the magnetic disk through heat. After the transfer film is removed, only the dry toner image and tackifier remain to press the image firmly on the disk.
According to the manufacturer Auto Tech, the system can produce up to about 300,000 disks per day. The above-mentioned production method is simple and effective, and provides synergistic benefits for disk content providers who seek security and photocopiers who wish to expand business opportunities.
HP Indigo
HP has created a combined solution for digital and security printing. HP also quoted that the problem of counterfeit products has caused global governments and the entire industry to suffer 334 billion euros in losses each year.
HP Indigo digital printing equipment provides a range of cost-effective anti-counterfeiting features, using HP ElectroInk liquid electronic ink and laser imaging technology.
Indigo can carry out variable data printing, including serially arranged codes, names and other unique features, such as:
-Invisible ink that will only appear under ultraviolet light;
-The code on the page, mixed with letters and numbers, and a series of numbers and letters that can only be read by special decoder
-Barcodes containing a large amount of information, and invisible barcodes that can contain security information in addition to images;
-Miniatures that are almost invisible to the naked eye but contain safety information;
-A digital watermark that can convert personal appearance and machine-identifiable patterns into digital images.
Potential function
The media has recently reported extensively on topics such as identity cards and other related documents, which is not difficult to attract public attention. Because government agencies around the world have discovered that this is a very useful invention, which can help reduce perjury and other related crimes.
Digital printing allows variable images to be printed, making it possible to personalize the print. Digital offset printing presses use UV-curable inkjet inks to print personalized identification documents. Based on this technology, Spectra has developed a prototype of a printing press that uses on-demand (DoD) piezo inkjet heads and high-temperature UV-curable inks.
In the past few years, various new anti-counterfeiting technologies have appeared in the market, and anti-counterfeiting ink is one of the most concerned.
Inkjet equipment manufacturers produce a variety of inks and toners that enhance anti-counterfeiting effects. Fluorescent inks, color-changing materials, DNA decoding inks, temperature-sensitive and photochromic inks, and pressure-sensitive materials can be used in piezo inkjet printing. This innovative printing method can undoubtedly have a major impact on product anti-counterfeiting. For example, temperature-sensitive inks that change color with temperature, and DNA decoding inks with biologically unique fingerprints are two powerful examples.
In addition, there are several technologies that are used in the field of digital printing but the original purpose is not anti-counterfeiting, and its anti-counterfeiting functions have also been discovered.
The best example is the technology of using piezo inkjet equipment to stick metal materials on plastic or paper. Another potential is the integration of conductive inkjet technology with existing printing processes. This technology can be applied to radio frequency identification tags (RFID), smart cards, anti-counterfeiting devices and other aspects.
AlpVision
Founded in 2001, AlpVision specializes in the development of digital printing technology to cope with the current serious forgery and infringement issues. One of the Cryptoglyph technologies is currently mainly used in brand and file protection (Figure 1).
According to AlpVision: “Since the progress of the anti-counterfeiting printing industry is slow and often relies on traditional and proven methods of operation, the stagnation of the industry has posed a major threat.†This shows that the market lacks effective and can combat all counterfeit products today Anti-counterfeiting printing scheme, and the combination of anti-counterfeiting printing and digital printing will be a feasible way out in the future.
Cryptoglyph is the best example of digital anti-counterfeiting. It uses ordinary ink to produce computer-generated authentication information. That is, Cryptoglyph is not visible to the human eye and can only be recognized by suitable equipment.
Cryptoglyph invisible logo loading data encrypted as 128-bit symbol password standard printing equipment with scanner detection and dispersion seamless integration
This technology has a wide range of applications, for example: as the company said, Cryptoglyph that cannot be copied can be used for anti-counterfeiting. In addition, because Cryptoglyph will not be damaged, it can verify the integrity of the data and serve as a sturdy label, so it can also play the role of location tracking.
Users do not need to use special instruments to apply technology to documents and products to enhance anti-counterfeiting performance. AlpVision pointed out that the technical principles they apply are simple and easy to understand:
"Cryptoglyph is part of the digital anti-counterfeiting feature and is detected by digital signal processing technology. The main goal of technological development is to read the anti-counterfeiting feature only with a general device. That is, to detect and verify Cryptoglyph, only a simple image capture device such as a scanner or The digital camera can do it. "
