If you’ve never heard of sleeking before, you’re not alone. Here’s what it is, how it works, and how to set up your files so your project turns out exactly as you imagined.
What Is Sleeking?
Sleeking is a digital finishing process that bonds foil or specialty finishes directly to printed toner.
Unlike traditional foil stamping, there’s no custom metal die required. That means lower setup costs, faster turnaround times, and more flexibility – especially for shorter runs or personalized pieces.
With sleeking, you can add:
Because there are no dies involved, every printed piece can be unique. That makes sleeking a great option for personalized direct mail, event invitations, employee recognition pieces, and other variable data projects.
Sleeking Tips:
Keep It Simple
Digital foil is at its best when it has room to shine. Bold logos, typography, icons, and graphic elements tend to produce the cleanest results. Extremely fine lines, intricate patterns, and delicate script fonts can be more difficult to reproduce consistently, so we generally recommend a minimum stroke weight of 1 pt.
Choose the Right Paper
Foil performs best on smooth, coated stocks and printable laminates, where it can bond cleanly and consistently. Textured and uncoated papers can affect adhesion, so if foil is part of your project, we’ll often recommend a stock that’s better suited for the process.
Leave Room for Registration
Like any foil process, digital foiling involves multiple passes through different pieces of equipment. As sheets travel through the press, there’s a small amount of natural movement. For most designs, it’s not noticeable. But if your foil needs to align perfectly with very thin printed elements or intricate artwork, we may recommend small adjustments to help achieve the best possible result.
How It Works
We begin by printing your full-color artwork with toner on our digital press. From there, we apply a printable laminate, most often a soft-touch finish. This seals the original artwork beneath a smooth, printable surface.
Next, we print a second toner layer containing only the elements that should receive foil. The piece then runs through our sleeking laminator, where heat reactivates that toner and bonds the foil to those designated areas.
Why add a layer of laminate? Without a printable laminate, foil would adhere to any toner printed during the first pass. That works well for some applications, but most designs contain logos, photos, backgrounds, and other printed elements that aren’t meant to be foiled.
The laminate gives us a clean surface to work from. Instead of relying on the original print, we create a dedicated foil layer that’s completely separate from the artwork underneath. The result is more precise foil placement and greater creative flexibility, especially on designs with photography, large areas of color, or layered graphics. As an added bonus, soft-touch laminate creates a rich tactile contrast with metallic foil.
Setting Up Your Files
Setting up your artwork correctly helps us produce crisp, clean results and keeps your project moving smoothly through production.
Whether you’re a seasoned designer or opening Adobe Illustrator for the first time, the goal is the same: help our prepress team understand which parts of your artwork should receive foil.
Separate Your Foil Artwork
If possible, place everything you’d like foiled on its own layer. Keeping specialty effects on dedicated layers makes them easier to identify during prepress and helps ensure nothing gets overlooked.
Use a Spot Color
The easiest way to identify foil artwork is with a spot color. A spot color is simply a way to tell our production team, “This part is different.” In this case, it tells us where you want the foil to go.
Name the spot color something obvious, like Gold Foil, Silver Foil, or simply Foil, and use a bold color that’s easy to distinguish from the rest of your design. Need more help? Check out our guide to preparing spot colors for specialty effects here!
Show Us What You’re Imagining
Spot colors are helpful, but they’re only one way to communicate your intent.
A simple key explaining what each spot color represents, a marked-up PDF, or even a quick mockup showing what you envision can be just as valuable. The more context you give us, the easier it is for our prepress team to understand your goals and make sure the finished piece matches your expectations.
