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

Behind every stunning product label is a well-crafted art file. In this guide, we’re diving into everything you need to know about white files and layered ink printing.

Why White Files Are Critical for Labels

What Is a White File?

A white file is a specific layer in your art file that tells the printing press where to lay down white ink on metallic, clear, holographic, or dark substrates to create opacity. This matters because most label printing companies rely on the CMYK color model, and your white file acts like a primer, ensuring those CMYK colors pop.

Imagine it like this: just as a painter primes a canvas so the colors stand out, your white file primes the substrate. Whether you’re going for a full coat that completely covers the substrate or a partial coat that lets some of the material shine through, the white file is key to getting your desired color effect without interference from the substrate.

Methods for Applying White Ink

There are two main ways to apply white ink, and your choice depends on the look you’re going for:

  • Flood Coats: With a flood coat, you cover the entire surface with white ink. It’s a straightforward approach that requires little extra file prep. Sometimes, using a white substrate might even be a more budget-friendly option. (Heads up: Performance can vary based on your substrate and ink formulation. We recommend doing a test run before you go full scale.)
  • Spot Applications: Spot applications let you apply white ink only where it’s needed. Your white file tells the prepress team exactly where to add the ink, ensuring that specific design elements stand out—like enhancing a clear label without covering up your container. (Note: Spot applications require precision. Make sure your file settings are dialed in and double-check with your prepress team to ensure everything comes out perfectly.)

Best Practices for White File Creation

File Preparation Techniques

  • Use Vector Images When Possible: Both Adobe Illustrator and Photoshop can create art files, but Illustrator’s vector-based approach gives you that extra precision. Vectors keep your layers crisp and reduce the chance of unwanted artifacts like a white fringe.
  • Layering—Keep White Files Above Your Art Layers: The white ink gets printed first, setting the stage for your CMYK colors. Keeping the white file on top ensures it shows up clearly on proofs and guides the printing process accurately.
    (Example: If you’re designing a label with a matte background and a metallic information box, position the white file for the lettering above the box layer. This prevents any overlap issues or lost details. Remember, it’s always a good idea to check your printer’s guidelines since layer handling can differ slightly between machines.)
  • Clear, Consistent Terminology: Name your layers with specific labels like “white ink” or “50 percent metallic” rather than vague names. This helps cut down on back-and-forth with your prepress team and ensures everyone’s on the same page.
  • Simplify Barcodes: While it might be tempting to experiment with creative barcode designs, sticking with a simple approach (black bars on a white background) is usually best for readability and scanner accuracy.

White File Preparation Checklist

Here’s a quick checklist to help you nail your file setup:

  • Use vector-based files (e.g., Adobe Illustrator) for clarity.
  • Place white file layers above all CMYK layers.
  • Name layers with clear, descriptive terms (e.g., “white ink – 100%”).
  • Test the file layout with sample proofs before full production.
  • Chat with your prepress team to confirm proper layering and settings.

Troubleshooting & Advanced Workflow Techniques

Even with the best practices in place, issues can occur. Here’s our step-by-step process to help you troubleshoot and fine-tune your workflow.

White File Workflow: Step-by-Step Process

  1. Initial File Setup:
    • Create your art file using vector software.
    • Define each layer with clear, descriptive names.
  2. Layer Arrangement:
    • Position the white file layer above all CMYK layers.
    • Use grouping and locking features to avoid accidental changes.
  3. Proofing and Testing:
    • Request sample proofs to check for consistency.
    • Adjust layer settings based on feedback from your prepress team.
  4. Final Adjustments:
    • Make adjustments based on your sample tests.
    • Finalize your file settings before sending them to production.

Holographic Labels: 4 Design Tips for Stunning Product Labels

When you have seconds to command consumers’ attention, holographic labels give you the means to keep all eyes on your products.

Holographic label materials are an increasingly popular packaging choice for good reason – these shimmering substrates add a whole new dimension for craft beer, specialty foods, and any other products in need of a visual spark. Let’s break down what goes into a holographic label and what you can do to get the most out of your packaging.

What are Holographic Labels?

The name “holographic label” comes from the iridescent effect these labels have on your packaging. The iridescent labels are made with a special film that creates a rainbow-like effect that allows your design to shimmer. Ink is printed on this holographic label material and protected with a laminate to protect your design. This helps protect your labels from scuffs, water, and any other potential hazards.

It’s also important to note that there’s a difference between holographic labels and hologram stickers. A security hologram is a sticker made with serial numbers or logos. Hologram labels are hard to counterfeit, so brands can use them to show authenticity and ensure original product protection. Holographic labels simply refers to the holographic effect of the material that the artwork is printed onto.

Holographic Label Design Tips

A good holographic label is a great way to attract attention. However, these materials can pose some potential design challenges that can impact the overall look of your label. Here are some key considerations to help you make your holographic labels captivate your customers.

Give the holographic label material room to shine

When you have something as stunning as a holographic label material, it’s important to think about empty space. Empty spaces on your label design allow the holographic effect to shine through without any obstruction from ink or other printed elements.

That empty space could be the entirety of your label that’s not covered in printed details like your logo and text – that’s certainly one way to create a stunning effect from all sides of your container. Empty spaces within design elements can also allow certain aspects of your design to pop out to customers. Both routes will certainly attract attention, so just make sure you give the label material the space it needs to show its magic.

Avoid additional gradients

While color transitions are visually appealing, there can be too much of a good thing. Holographic label materials already add that color-shifting rainbow effect to your packaging. Adding a gradient will only jumble up the color transitions of your label even further.

Use white ink to block out the holographic effect where needed

While that holographic sheen is certainly stunning, there are some elements that need to stand out on their own. Certain label inks are translucent enough that the holographic effect can show through details like text or logos if you’re not careful. As such, you’ll need to take measures to block out that effect for any areas that should be opaque.

If you need to block out the holographic effects, have your printer lay down white ink to create opacity on holographic substrates. You’ll need to include a specific layer called a white file in the art file to lay out exactly where this white ink should go. If you need more information on how to go about this process, check out our post on white file best practices.

Pair holographic label materials with the right laminates and varnishes

The last thing you want to do after investing in gorgeous holographic labels is to cover up what makes them special. Laminates and varnishes play an important role in both print protection and the overall aesthetic appeal of your product labels. However, certain laminates and varnishes are better suited for holographic labels than others.

Glossy laminates and varnishes are generally the best options for holographic label materials. The reason for this is simple – matte finishes will end up dulling the holographic effect. A glossy laminate or varnish will not only allow the holographic material to completely shine through, but also protect your ink from scratches, scuffs, and other hazards.
