Digital Operator Q&A: Correcting Inconsistent UV Coating and Web Breaks
Question From An MGX Customer & HP Indigo Roll Press Operator:
Our company has experimented with cheaper digital stocks from other suppliers. While attempting to print on some of these products, we are experiencing inconsistent UV coating and frequent web breaks. We’ve also noticed a shorter blanket lifespan: we are finding that we need to replace the blanket more often then we used to. All of these issues are causing downtime on our press and the UV coating inconsistencies are resulting in rejected labels, reprints and waste. Why are we experiencing these problems with non-MGX stock?
Answer:
It is likely the stock that you are describing hasn’t been treated with a contiguous coating. Every MGX digital material is optimized with the best contiguous coating process in the industry, which will give you the best possible print quality, consistent UV coating, and long blanket life. Other materials on the market are not coated; rather a digital solution is mixed in the pulp at the time of manufacture. This method of treatment is usually less expensive but can cause a multitude of digital press issues including brittleness, web breaks, inconsistent UV coatings, and shortened PIP and blanket life. Here’s a little more detail on the issues raised in the query above:
Coated vs. Non-Coated Materials 
Substrates can be digitally treated when the paper is manufactured by mixing digital coating with the paper fibers. This creates a substrate with digital coating “peppered” throughout the entire substrate. Digital inks will adhere to this coating during printing; however, this coating method leaves many areas of the substrate untreated for digital printing. As you can see in the diagram on the right, the black orbs in the diagram illustrate the digital-receptive coating. As the picture shows, many microscopic areas of the material’s surface will be left without digital treatment. Because of this, digital inks will only adhere to the portions of the material that contain the digital coating, leaving many uncoated “holes” within the material. Therefore, digital inks can lift off of the non-coated portions of the substrate which can cause picking and ink lift-off. Ink lift-off from the substrate can also stick to the digital press blanket, leading to more frequent blanket replacement and press downtime.
UV Coating Inconsistencies
The entire surface grain of these other materials is not consistently coated, which can lead to inconsistent UV coating. One MGX customer experienced these problems when using a cheaper, non-coated product – a glossy UV coating appeared matte and splotchy on the finished printed product and was subsequently rejected by the client. Another downside to this coating method is that the digital treatment is embedded throughout the substrate and not just on the surface of the material. This can cause the substrate to be brittle, causing web breaks, downtime, and potential problems on your press. One MGX customer using a non-coated material experienced three web breaks and over an hour of downtime on their machine due to the brittleness of the non-coated stock.
Digital materials coated with a contiguous coating method are evenly coated throughout the surface of the substrate. You can see the difference in the graphic (right), with the digital coating pictured in black. As the diagram illustrates, contiguous coating leaves no breaks or “holes” in the coating so the ink is always in contact with the digital treatment. Substrates with contiguous coating feature heavier ink coverage so colors have the potential to be as rich and vibrant as possible. Items digitally printed on contiguous-coated substrates are also more robust and durable with little to no ink lift-off in tape tests and less web breaks during production.
Extended Blanket Life
Contiguous-coated materials also extend the life of your blanket as there is less residual ink that adheres to the blanket. Digital ink that flakes off the non-coated portions of the substrate will stick to the blanket, leading to more frequent blanket replacement and less downtime. Extended blanket life saves you time, money and maintenance hassles.
Security Printing 101: How to Utilize Digital Printing & Security Technologies to Protect Your Customers
With advances in digital printing, photography and scanning technologies, counterfeiters have more tools than ever to mimic a product. These technologies make it easy to copy a brand and hard to discern a genuine product or document from a counterfeit. As new security printing and packaging technologies emerge, copycats quickly take note and scramble to produce reproductions of the new process. Therefore the brand protection and security market is constantly developing new technologies and processes to stay one step ahead of criminals.
Why do counterfeiters take such extreme measures to produce realistic copies of a product? It’s profitable to copy a successful product, piggybacking on the item’s sales and stealing potential revenue from the original manufacturer. According to the International Authentication Association (IAA), the illegal practice of counterfeiting costs industries anywhere between $200 billion and $600 billion dollars per year (see L&NW article). All industries are susceptible but some face more risks than others: Pharmaceuticals, software, music, automobile/machinery parts, and movies are all markets that currently combat fraudulent reproduction of their products. Even brand-name commodities and licensed products face the risk of counterfeit.
Essentially there are four categories of brand protection strategies that printers and manufacturers can choose to implement individually or as a combination for security printing:
- Overt: This category is obvious to both the customer and the manufacturer, and is classified by the unique packaging or look of the product or brand. One of the most common forms of overt security packaging is tamper-evident labeling. Other examples include complex label graphics that are difficult to replicate, or the use of hard-to-attain holographic or exotic material within the design. This strategy is coincidentally the most complex because in many cases the unique packaging is exactly what the counterfeiter is trying to copy.
- Covert/Forensic: These security features are hard to identify by the customer or even the naked eye. However, covert features are hard to mimic because they are hard to identify without specialized equipment. One application of covert packaging is to incorporate security ink into the printed product so the image fluoresces when placed under ultraviolet (UV) light Kodak Nexpress recently released red florescent ink that is invisible to the naked eye but can be used for security printing applications. A printer may also choose to utilize security paper into the product which when copied, displays a message that deters counterfeiters.
- Numbering/Coding: Digital printers are perfectly poised to utilize variable data as a security feature for their customers. Setting up a system that is unique to each item is a way to be certain that each product is unique and therefore hard to mimic. Utilizing algorithms, sequential numbering or custom barcodes to create a custom label for each product is a way to integrate security as well as information into the product. These forms of variable data can contain useful data such as print date or product origin.
- Information Linkage: Advances in digital technology has allowed manufacturers to use embed “smart” sensors within their products so they can track and identify their items easily. The most common form of information linkage security packaging is radio-frequency identification (RFID). These smart sensors can be embedded in the packaging upon manufacture, which allows for scanning of an item to determine authenticity. RFID tags can even track movement of items within a certain area with the right equipment. RFID technology is an emerging and developing tool which may come to replace conventional barcodes in the future.

Application Corner: 3D Substrates – MGX Lenticular vs. Azuna® 3D Bubble Sheets
In retail, direct mail, and manufacturing, companies are struggling to differentiate themselves from their rivals by utilizing eye-catching characteristics in their product offerings. As a digital printer, it is important to be able to offer clients materials and options that will help them stand out from their competitors. 3D substrates are an excellent way to help your customers literally “stand out” from the rest by displaying text and high-quality graphics that jump off the page or change images. Masterpiece Graphix currently stocks HP Indigo-compatible Lenticular and Azuna® 3D Bubble sheets. Both plastic substrates are durable and extremely diverse, and are both applicable to a multitude of similar end-uses. However, there are advantages as well as limitations to consider when utilizing either substrate.
With lenticular sheets, you can produce a 3D effect, do 3D imaging, demonstrate movement with multiple frame animation, “flip” from one image to another, or “morph” two dissimilar images together, or any mix of the aforementioned processes. MGX Lenticular allows an image to be reverse-printed on the smooth side of the plastic on an HP Indigo S2000 press. The ink can then be laminated for additional image protection.
Masterpiece Graphix offers two types of in-stock Lenticular material: 75 LPI and 100 LPI Lenticular as 12”x 18” sheets. LPI, or lenticule per inch, determines the resolution capacity of the substrate. A higher LPI equals a higher resolution image. MGX 100 LPI Lenticular is a higher-quality substrate that is unavailable through other suppliers.
For any MGX Lenticular image effect to work, multiple images must be properly aligned, or interlaced, and the material must have a square, even cut prior to printing. Interlacing is when the multiple images that create the desired effect are “cut up” and strategically reassembled via specialized software to complete the visual illusion of depth or movement. A misaligned cut can slice into part of the morphed image which can ruin the desired finished effect. A perfectly parallel straight cut is guaranteed on all MGX Lenticular sheet products to ensure the quality of the finished image.
There are a few limitations in utilizing Lenticular in an application. MGX Lenticular sheets are only recommended for use on the HP Indigo S2000. Furthermore, specialized software such as HumanEyes or PhotoIllusion, is required in order to morph the images together and to create the finished piece.
Azuna® 3D bubble synthetic sheets is an innovative material that when printed creates a 3-D effect that is similar yet different to the 3D look of lenticular, which can be utilized without costly software or art setup charges. In addition, Azuna® 3D bubble sheets are compatible with any HP Indigo sheet press with a thick substrate upgrade.
Masterpiece Graphix currently stocks Azuna® 3D Large Bubble 12”x 18” HP Indigo-compatible sheets. The substrate is also available as a small bubble pattern by request. The look of the substrate reminds one of raindrops on a windowpane; the final effect creates the illiusion of 1-2” of depth, with images appearing at the front or back plane of this depth.
With Azuna® 3D, text and images appear to float which creates a three-dimensional look similar to that of 3D lenticular. The substrate is optimized to be printable on either side, allowing printers to choose the desired finished look depending on which side of the material is printed on. If the Azuna® sheet is surface-printed, the floating text and image look is achieved with the printed image appearing to be in front of the bubbled material. If the image is reverse-printed, the “bubble” look of the material appears to be in front of the printed image.
Although images still “pop” off of the substrate with a 3D effect, Azuna® 3D bubble sheets don’t have quite the versatility of lenticular. The substrate cannot demonstrate movement or morph between two dissimilar images like lenticular can. However, any HP Indigo sheet press user can utilize Azuna® without specialized 3D software like HumanEyes. The substrate prints on any HP Indigo sheet press with a thick substrate upgrade, and is not limited for use only on the HP Indigo S2000 model.
Other custom 3D substrates are also available through Masterpiece Graphix. For substrate samples or more information on 3D substrates and how to apply them to a particular end-use, please contact your MGX sales rep.

Application Corner: MGX Flexible Packaging Provides New Revenue Opportunities
Anywhere you look on retail shelves, flexible packaging, or flexpack, is emerging as an economical and practical option for prime packaging. According to the Flexible Packaging Association, the total size of the flexible packaging industry was $25.6 billion in 2008 (see article). With the trends that are emerging in digital packaging, there is no reason that the flexpack market will not increase along with digital press use in the coming years.
Flexible packaging presents an opportunity for narrow web digital press users who currently print pressure-sensitive tags and labels to expand their product offerings for additional revenue streams. Its unique characteristics make it an ideal digital substrate.
There are many reasons why a brand manager would select flexpack for a digital press application:
- Short Runs: Printers can produce small quantities of flexible packages economically, making the design ideal for smaller brands or sample sizes. Short run packaging also
allows for mass customization of products tailored to the specific needs of the consumer. Combined with the variable data technology of digital printing, customization can be taken a step further. Digital press users can create unique packaging graphics with different dynamic data such as serial numbers and barcodes for each item printed. With fast on-demand digital printing, printers can produce lower quantities on an as-needed basis, reducing inventory and warehouse space.
- Cost-effective & Greener Packaging: Packaging constructed with flexpack technology can reduce material costs as well as the size and weight of the finished package. Smaller, lighter packages take up less space, reducing warehouse space and transportation costs as a result. In addition, reduction in packaging materials can be economical, cutting material costs. In combination with digital’s profitable short-run advantages, flexible packaging presents itself as an economical choice in today’s market.
- Barrier Construction: Flexible packaging contains layers of materials that create a functional barrier, lending itself to many product applications. Barriers keep contents fresh in food packaging. Barriers are also useful in chemical packaging to keep potentially hazardous material within the package.
- Convenience: Flexpack is the ideal way to produce snack containers or smaller single-use portions. The economical advantages to flexible packaging make it an excellent choice for shorter-life products or convenience items.
Masterpiece Graphix is the one-stop resource for digital flexible packaging materials and information, and can supply all of the substrates you need for your specific application. Digital-ready heat-sealable films, cosmetic web, co-ex, LDPE, BOPP, polyester, and snack web are just a few of the flexpack substrate options that MGX offers.
