Digital vs. Flexo Printing: Which is Right for Your Labels?

Quality labels play a pivotal role in any product. However, there’s more than one way to manufacture your custom labels.

Digital and flexographic label printing are both viable ways to make product labels, but it’s not always obvious why one would be better than another for your business. Let’s break down the differences between the two printing processes (and how you don’t always have to decide between the two).

Flexographic Printing vs. Digital Printing: How They Work

The differences between flexographic and digital label printing largely boil down to how the two processes work. Each method aims to accomplish the same task – print product labels. However, the way they go about this task is very different.

The flexo label printing process

Flexo label printing is the old-school approach where ink is physically pressed onto either film or paper. This process uses custom rubber printing plates to stamp your design onto the label material. These plates are attached to cylinders so that the flexographic printing press can make multiple imprints on a roll of labels. Larger projects will sometimes avoid the rubber plates and engrave the label design directly on metal cylinders instead to accommodate massive quantities.

The problem with flexographic printing is that its various costs can add up rather quickly. Every color will need its own plate for your design, which means you’ll need multiple custom plates for every design.

That number increases dramatically if you have multiple SKUs. Let’s say you need labels for four different SKUs and each of them needs four different colors. That’s 16 total plates that you’ll need to pay for if you go with flexographic printing.

There are additional costs associated with this flexographic printing. Time and labor is a factor as well. Flexographic printers need to align each plate to create a perfect imprint on each piece. This process isn’t short – some jobs can take days to set up properly. Testing these setups also requires a lot of waste material. It’s not uncommon that 15 percent or more of your material costs go toward waste accrued during flexographic setup.

So why would businesses turn to flexographic label printing if there are so many initial costs and delays? This method is well-suited to handle large-scale label printing projects. Larger quantities help amortize initial costs over a long print run of labels, which is why massive businesses, like Budweiser, use flexographic printing for millions of labels. However, that same scale is less likely to be realistic for small to mid-size businesses.

The digital label printing process

Digital printing eliminates the need for plates in favor of using technology. Digital label printing presses read art files that lay out your design and call out specific Pantone colors and other key instructions. The printer then uses an electrophotographic process to transfer images onto a material. HP Indigo printers use heated blankets to blend electronically charged particles into a smooth film. This process creates a defined image on the blanket, which in turn is transferred onto the label substrate.

Because of the lack of custom plates and lengthy setups, the digital printing process offers businesses a lot more flexibility and cost-saving capabilities. Because of how they’re made, flexographic presses will use a lot of spot colors. Digital presses do CMYK blending to achieve full color label printing without the need to source different inks for every hue.

Digital label printing is also a much more scalable option. By cutting out tooling and setup costs, digital printing can help accommodate your label needs with quicker turnaround times. That time savings means that you’ll get your labels sooner than you would if you had to wait for new plates any time you adjust your order.

While digital offers several advantages, there are some occasions when the flexographic printing technique is necessary. For example, plates are needed to apply flood or spot coats onto labels. In addition, digital printing technology hasn’t quite come far enough to accommodate more than a few select metallic, fluorescent, and pastel inks. Until those specialty inks are developed, you may need some form of flexographic process to enjoy those types of capabilities.

Combine Digital and Flexographic Label Printing for the Best of Both Worlds

While both digital and flexographic label printing offer certain advantages, you don’t necessarily have to settle for one or the other. Digital label printing is adaptable enough to include flexographic into its finishing processes so that you can enjoy the benefits of both.

During the digital label printing process, printed labels go through a finishing machine to put on final touches such as decorative treatments or print protection. However, some digital label printing companies have flexographic stations incorporated into the finishing process to address specific needs like flood coats or fluorescent inks.

As with traditional flexographic printing, these added finishing processes will still require plates for any custom designs. However, the costs and time associated with tooling and setup are drastically reduced since you’re only making a single plate. Flood coats of white ink or label varnishes won’t require any plates either, as they require a solid stamp that’s already available in-house. In short, you’re still able to achieve the benefits of flexographic printing without all the extra investment or delays.

White File Best Practices: The Importance of White Ink for Labels

Every great product label starts as an art file. These files play a key role in helping your label printing company take your design and turn it into a stunning label. In addition to your design, art files contain important details to create a specific look and avoid potential printing issues. One of the most important elements of this process is the white file.

Why White Files are Important

A white file is a specific layer included in your art file. This layer instructs the printing press to lay down white ink on a metallic, clear, holographic, or dark substrates to create opacity. This process is important because label printing companies use the CMYK color format for physically printed items like product labels.

White files play a key role in supporting the CMYK color format because it can help you capture the correct color for metallic, clear, and other types of substrates. A full coat of white ink allows you to mask the substrate – it’s like printing on white paper at that point.. You can also do a partial coat of white to allow some portion of the substrate to show through, such as a slight metallic sheen. Either way, the white file allows you to capture the color you want instead of the color or effect of the material over powering your design.

Different Methods for White Files

There are a couple of different ways to use white ink for your labels. These approaches differ largely based on what you want to achieve with your design. These methods are:

  • Flood coats
  • Spot applications

A flood coat is used when you need to cover an entire surface with white ink. Since a flood coat covers the entire surface of a substrate, you don’t need any additional file preparation. In some instances, it is good to note that a white material might be a more economical choice if you are needing to flood coat.

Spot applications are used to apply specific patterns of white ink to substrates. The white file is used to indicate to a printing company’s prepress team exactly where the white ink should be applied for your design. For example, you may want a clear product label to showcase your container (or even the products within that container. A spot application notes exactly where a base coat of white ink should go to support the individual elements of your design.

White File Creation Best Practices

You’ll need to prepare an appropriate layer to call out spot applications of white ink in your art file. Our white file creation guide can give you need a step-by-step breakdown on how to prepare your art file for white ink. In addition, it’s important to remember the following best practices to make sure your white file is set up for success.

Use vector images if possible

While you can create art files for labels with both Adobe Illustrator and Photoshop, Illustrator can lead to a smoother process. Photoshop uses pixel-based raster images, while Illustrator works using layered vector files. These layers allow you to make your desired white file clear, whereas a label prepress team would need to make some design decisions with raster images.

For example, a prepress expert may need to make pixel-by-pixel judgments for where your white file ends in a flat raster image. That judgment call could leave a white fringe around a certain element of your design, which you may or may not want. By using a vector image in Illustrator, you can make your design preferences clear.

Mark white files as a layer above your label art

While the white ink is printed onto the substrate before the CMYK ink, white files should be added above the label art in your art file. This process makes it very clear on label proofs where white ink should be added during the printing process. When white files are placed below the CMYK layer, it can hide key information that’s important for your design.

This process can be tricky, especially if you have certain design elements within other elements. Let’s say you want a label with a matte background, but you have an information box that you want to be metallic. That information box should be in a layer above the label background. The white file for the lettering within that information box should then be in another layer above that information box layer. If the white file were tucked below, it could get lost in translation. As such, keeping white files above their respective art layers can make sure white ink is applied exactly where it’s needed.

Clear, consistent terminology

It’s important to be as clear and consistent as possible when naming art file layers. In general, it’s good to name your layers as “white ink” or with a description of how you’d like the layer to look.

For example, you may need a white file that still allows some amount of the metallic substrate to show through the ink. In this case, naming the layer “50 percent metallic” will clearly show how much white ink is needed under the CMYK ink. By using clear, consistent layer names, you can reduce the amount of back-and-forth discussions necessary to achieve your ideal label.

Simplify barcodes

While you may be tempted to do a metallic barcode or some other interesting design, it’s best to use a simple color scheme for your barcodes. You want to have enough contrast between the bars and the background to ensure that scanners can read your barcode.

Black bars on a white background is typically the safest route. A solid base of white ink to support your barcode in this scenario is a great way to support the barcode.
