Best Shirt Fabrics for Printing vs. Embroidery (Ring-Spun, Tri-Blend, Heavyweight)
September 20, 2025When you start designing custom t-shirts or other apparel, one of the first decisions you’ll make is how many ink colors to include in your design. It may seem like a small detail, but the number of ink colors directly impacts the cost of your order, the production process, and even how your final product looks and feels.
At RKT Shirts, where we specialize in screen printing and embroidery, we work with customers every day who are unsure how to balance their design ideas with budget and production realities. Understanding ink colors and separations can help you make better decisions about your artwork before you even request a quote. In this article, we’ll break down what ink colors mean in screen printing, how separations work, and how these choices affect pricing.
What Does “Ink Colors” Mean in Screen Printing?
When printers talk about “ink colors,” they’re referring to the distinct shades of ink used to bring your design to life. If you want a design with just black text, that’s one color. If you add red to the design, that’s two colors. Each color requires its own screen and pass on the press.
This means that even if your design looks simple, the printer has to prepare, align, and print each color separately. The more colors you add, the more complex and time-intensive the process becomes. That’s why you’ll often see pricing structured around the number of colors in a design. A one-color print is the most affordable, while multi-color prints add to the cost.
Why Separations Are Necessary
Ink separations are the behind-the-scenes process that allows your design to be printed cleanly. When you submit a piece of artwork, your printer has to break it down into its individual color components. Each color layer is output onto a film, which is then used to burn a stencil into a screen.
For example, if your design uses three colors—say, navy, white, and gold—your printer will create three different screens. Each screen corresponds to one of those colors. During printing, those screens are carefully registered (aligned) so that when the inks are applied, they line up and create your full image.
Without separations, the design wouldn’t translate accurately onto fabric. Think of it like printing a magazine image: the photo looks seamless, but it’s actually made up of layers of tiny color dots. Screen printing works in a similar layered way, though usually with solid blocks of color.
The Impact of Ink Colors on Pricing
Most screen printers structure pricing around two key factors: the number of garments being printed and the number of ink colors used. More garments usually lowers the per-piece cost, while more colors usually raises it.
Here’s why: every ink color requires its own screen to be created, aligned, and cleaned after the job is done. Each setup takes time, labor, and materials. Even though RKT Shirts waives setup fees when you meet the 15-piece minimum, it’s important to understand that adding colors still adds production time.
For instance, a one-color print on 50 shirts is straightforward. But a six-color print on the same 50 shirts requires six screens, six setups, and six printing passes. The time investment grows significantly, which is reflected in the overall pricing.
Spot Colors vs. Process Printing
Not all colors are created equal in screen printing. When people talk about “spot colors,” they’re referring to solid, individual ink colors used directly in the design. Spot colors are great for logos, text, and bold designs with clean edges.

On the other hand, process printing—often called CMYK—uses cyan, magenta, yellow, and black inks layered in tiny dots to simulate a wide range of colors, much like a home printer. This technique is used for photographic or highly detailed designs.
Process printing can reduce the number of screens compared to trying to match dozens of colors, but it requires precise calibration and high-quality artwork. It’s not always the best choice for every project, especially if consistency of color (like brand-specific Pantone shades) is a priority.
When Fewer Ink Colors Make Sense
If you’re working with a budget or just want a clean, classic look, reducing your color count can be a smart move. Many customers are surprised at how effective a one-color or two-color print can be. High-contrast prints, tone-on-tone effects, and creative placement often look just as striking—sometimes even more so—than complex multi-color designs.
Schools, sports teams, and nonprofits often lean toward fewer colors because it keeps costs manageable while still delivering strong results. A simple one-color logo on the front of a shirt can look professional and bold, especially when paired with the right shirt color.
When More Ink Colors Are Worth It
There are times when adding more colors is worth the investment. If your design relies on gradients, shading, or photo-quality detail, you’ll likely need more separations to capture the artwork accurately.
For example, a band t-shirt with a detailed album cover might lose too much detail if reduced to one or two colors. Similarly, companies that rely heavily on brand recognition may require exact Pantone matches for logos, which sometimes means adding more screens to nail down the right look.
The key is to balance your vision with your budget. A good screen printer will advise you if a design can be simplified without losing its impact or if it truly needs additional colors to do it justice.
The Role of Pantone Matching
Consistency matters, especially for brands. That’s where Pantone color matching comes in. With Pantone matching, a screen printer mixes ink to match a standardized color reference. This ensures your blue always looks like your blue, no matter when or where it’s printed.
At RKT Shirts, Pantone matching is available for $20 per ink color. While this adds a bit to the cost, it’s often worth it for businesses or organizations that want consistency across multiple print runs or across different types of apparel.
Artwork Prep and File Considerations
Your artwork file plays a big role in how smoothly separations and color setup go. Vector files (AI, EPS, or original editable formats) are always best because they allow your printer to easily isolate and adjust colors. Raster files like JPEGs or PNGs can be used in some cases but may require extra design time to prepare for print.
Remember that part of our process at RKT Shirts includes an artwork review with up to an hour of design time and two revisions included. This ensures that your design is separated properly and will print as intended, without hidden surprises.
How to Decide on the Right Number of Ink Colors
Ultimately, the number of ink colors you need comes down to three questions:
- What does your design require to look its best?
- What’s your budget for printing?
- How important is exact color matching for your brand or event?
If you’re unsure, start with your design as-is and ask your printer for recommendations. Sometimes you’ll discover that the design can be simplified without sacrificing its impact, while other times you’ll realize that additional colors are essential.
A good printer will walk you through the pros and cons of different options so you can make an informed decision that fits your goals.
Final Thoughts
Understanding how ink colors and separations work can make the ordering process less intimidating and more cost-effective. Every additional color means another screen, more labor, and higher costs, but also more flexibility for detailed and vibrant designs.
If you’re planning a custom screen printing project, think carefully about how many ink colors you truly need. Sometimes less is more, but sometimes more is worth it. The key is knowing your priorities and working with a printer who will guide you through the process honestly.
