Varnish, Aqueous or UV Coating: What’s the Difference? Which Should You Choose?
In this blog, we’ll explore how varnishes are used in printing, the key differences between the various types of varnishes available, when you should use a varnish, and when you shouldn’t. We’ll also reference Ceres products throughout to help you identify the best solutions for your needs.
What Is a Varnish?
A varnish is a coating applied to your printed piece either during or after the printing process. In printing, varnishes serve two primary purposes—both of which are enhanced by Ceres’s specialized varnish formulations:
To highlight key design elements
To protect printed surfaces from scuffs and scratches
How Are Varnishes Used in Printing?
There are two main ways to apply varnishes to printed materials, and Ceres offers tailored products to support both methods:
1. Spot Varnishing
Spot varnishing involves applying varnish to specific areas of a page. It uses contrasting gloss and matt finishes to draw attention to images, headings, or logos—adding subtle yet impactful design detail. This method requires a custom plate for the printing press.
Ceres Spot Varnishes stand out for their exceptional flow and precision. They adhere perfectly to custom plates, ensuring sharp, clean edges for the varnished areas and avoiding uneven gloss or bleeding. This makes them ideal for emphasizing brand logos, product photos, or text that needs to “pop.”
DESIGN TIP: Treat spot varnish like an additional color in your design. Use a solid shape to mark the varnished area and label it with a spot color named “Spot Varnish” to ensure accuracy during production.
2. Flood Varnish (or All-Over Varnish)
A flood varnish covers the entire surface of a printed sheet. Its primary role is to act as a protective sealant, preventing scuffs, smudges, or ink wear during handling, cutting, binding, or shipping.
You don’t need to include flood varnish in your design file—simply let us know you want to add it for protection. We’ll recommend the right Ceres Flood Varnish based on your substrate (e.g., coated paper, uncoated paper, or cardstock) to ensure even coverage without dulling the original print colors.
Don’t worry if you forget to request it! Our experienced team will proactively suggest Ceres Flood Varnish if we determine it will benefit your project (e.g., for high-use items like business cards or brochures).
When Should You Use a Varnish? When Should You Avoid It?
When to Use a Varnish
For high-use items: If your printed piece will be handled frequently (e.g., bookmarks, pocket folders, business cards, or product packaging), a varnish is essential for extending its lifespan. Ceres Varnishes boost surface durability by over 30%, reducing scratches, creases, and fingerprint marks.
For design enhancement: A selective gloss varnish (like Ceres High-Gloss Spot Varnish) paired with a matt base creates striking contrast, making key elements (e.g., product images or headlines) more eye-catching. This is perfect for marketing materials like brochures, flyers, or luxury packaging that need to convey premium quality.
When to Avoid a Varnish
Avoid varnishes if your printed piece needs to be written on (e.g., greeting cards, postcards, or forms) or if it requires inkjet printing on specific areas. Most varnishes—including standard formulations—create a smooth, non-porous surface that prevents pencil or pen ink from adhering. Even permanent markers may smudge on varnished surfaces.
For this reason, we recommend skipping varnishes for items that need handwritten notes (e.g., wedding invitations with RSVP sections) or variable data printing (e.g., personalized labels).
The Verdict
There are countless reasons to use different types of printing varnishes, and the best choice depends on your project’s end use and desired effect. Varnishing not only elevates the perceived quality of your print but also protects it—all while being a cost-effective, easy-to-implement process (whether adding spot finishes or full coverage).
A major advantage today is the availability of eco-friendly options—and Ceres leads the way with its low-VOC (volatile organic compound) and biodegradable varnish range. These formulations meet strict global standards (e.g., EU REACH, US FDA) and are ideal for food packaging, children’s books, or sustainable brand materials, as they reduce odor and environmental impact.
Remember: Your business card, brochure, or packaging is often the first impression customers have of your product or service. Take this opportunity to stand out—add a gloss spot UV or Ceres Spot Varnish to enhance photos, logos, or text and leave a lasting impression.
We’d love to discuss how a varnish or UV coating can elevate your project—and which Ceres product is right for you.
