Color Matching Guide for Print-on-Demand Products

By Reading Time: 8 minutes

First and foremost, you’re the designer in charge. You want your work to come out as you envisioned it, and don’t want to risk the printing software misrepresenting the colors you chose.

Second, color matching is crucial because you want to meet your customer expectations. Remember those “expectations vs. reality” online shopping memes? Imagine that happening to a customer with your products. Yikes.

And third, beautifully cohesive colors just look better and that’s another point why you should focus on color matching from design files to prints.

Here’s what we’ll go through to master the art of color matching:

  1. The basics of color matching
  1. Why printed colors look different from digital designs
  1. Steps to getting the print colors you want

1. The basics of color matching

The writer Roy T. Bennett noted: “It takes sunshine and rain to make a rainbow.” Same goes for color matching.

Before we wander into the world of color, let’s go through my glossary of color printing terminology so you can get a better grip on color matching.

Color design and printing glossary

  • Color model—the mathematical formula of a color. The numbers of the formula express what other colors a given color consists of.

  • RGB—a color model where the formula of a color is expressed in three primary colors: Red, Green, Blue. 

The RGB color model is based on the way how we see colors—with the help of light. Similarly, the RGB color model is used to display images on devices that emit light.

  • CMYK—a color model where the formula of a color is expressed in four primary colors: Cyan, Magenta, Yellow, Key (black).

All printers use the CMYK color model. The printed colors are created by overlaying the four colors in CMYK.

The bluish color in the printed image on the left is a blend of cyan, magenta, yellow, and black. The image on the right is what the color formation looks under a microscope.
  • Color space—a range of colors produced by specific color models like RGB, CMYK.

Each color model has its own color space and limitations to what it can display. The way color is displayed varies across devices too. For example, the colors you see on your phone screen will look slightly different than on tablets.

  • Color values—decimal and / or letter combinations used to represent colors.

Each color spaces have different values for displaying a color. The screenshot below shows how the same color is displayed for different color models. 

  • Color profile—the limit of how many and which colors are displayed within a color space.

Color profiles define the color values within a color space they were created in. For example, you take a photo of a tomato and then upload it to Instagram. Your phone will then pass the color profile information to Instagram, so your tomato photo is in the shade of red it was captured in. Most common color profiles are sRGB and Adobe RGB for the RGB color model, SWOP V2 and Fogra39 for CMYK.

At Printful, we recommend saving and uploading design files in the sRGB color profile, sRGB IEC61966-2.1 to be exact!

Our DTG printers work with an upgraded CMYK color space. We’ve added more ink colors, allowing us to achieve print colors that fall outside of the CMYK color range. The closest color space to our upgraded CMYK is the sRGB and that’s why we recommend it for print files.

  • Color gamut—a range of colors which can be represented within a given color space.

When you convert a digital design to a different color space than you designed it in, you alter its gamut. Some of your original colors can change to the closest available colors in the color space you converted it to.

The RGB color space has a broader color gamut than CMYK, so you can lose colors (especially bright neons) when converting a design created in RGB to CMYK.

  • Color matching—a technique used for matching a color from a digital design file to a design printed on a product.

Color matching is usually done using a design software like Adobe Illustrator or Photoshop.

Now you know all the whats related to color matching and color design. You’re ready to understand the whys.

2. Why printed colors look different from digital designs

Never in a million years will your designs on screen match the ones on your printed product 100%. Yup.

There are various factors that contribute to color inconsistencies. Let’s go through them so you know what to look out for the next time you’re designing!

Design color spaces

CMYK is the color space that’s used for printing designs. RGB, on the other hand, is the color space used by most creators when designing print files and due to technicalities, it’s the color space we recommend uploading your design files in.

Most beginner or web design software supports only the RGB color space. Advanced design programs (see our blog on free Photoshop alternatives!) allow you to switch between the RGB and CMYK color spaces.

If you’re working within the RGB color space and upload that design for printing, our printing software will convert it to the CMYK color space it supports. That’s the risky step where your design can lose some colors it originally had.

The CMYK color space recognizes a smaller range of colors than RGB. If your design has colors outside of the CMYK color space, then our printing software matches those colors to the closest ones in the CMYK color space.

The original photo taken within the RGB color space is on the left. The photo on the right is the same one, converted into the CMYK color space.

To take color matching in your hands, design within the CMYK color space and then convert to RGB yourself, without losing any colors. Or, if your software doesn’t support the CMYK color space, use an online RGB to CMYK converter to check which colors of your design are out of CMYK color space and adjust those.

Tip! Try out the color space converter. Select the output format as .jpg and set the CMYK profile to SWOP2006.

Types of fabric

Your print outcome varies depending on the fabric you choose to print on. Printful has plenty of options to pick from, like:

  • 100% cotton
  • Poly blends (50% cotton/50% polyester)
  • Tri-blends (50% polyester/25% cotton/25% rayon or 50% polyester/37% ring-spun combed cotton/13% rayon)

We tested how DTG prints show up on different fabric. Fabric made of 100% cotton has a tight weave and, for that reason, it’s the best choice to show off your design in its full opacity. Thicker 100% fabric is more likely to absorb ink, so the final print can have a bit of a faded effect.

Fabric made of poly and tri-blend has a looser weave and, for that reason, it’s the best choice to show off your designs in a faded / vintage kind of vibe.

The differences between prints on 100% cotton (left) and tri-blend fabrics (right).

If you like your designs to have a faded color palette, go for products with blended fabric. If you want that maximum opacity, choose products with 100% cotton.

Fabric colors

The same color will look different depending on the color of the fabric your design is printed on. In the image below, compare the orange color from the top on the black garment, and the same color on the white.

At Printful, we print a white underbase layer beneath prints on colored and dark garments to keep the designs vibrant and colorful. When choosing the right colors for your design, I’d even suggest going with darker shades for lighter colored fabrics to get a more vibrant design.

Let’s go through the steps you can do to assure your design comes out exactly as you envisioned it!

3. Steps to getting the print colors you want

The ideal scenario to get the perfect print color is a combination of actions. I’ll sort these steps, starting with the easiest and most important one.

Avoid neon colors in RGB or create design files in CMYK

Remember that neon colors and deeply saturated shades exist in the RGB color space, but our printers support the narrower, neon-less CMYK space.

For the best color quality, you have two routes:

1. Create design files in RGB and steer clear of neons and saturated shades as they simply won’t print!

2. Create design files in CMYK and experiment with neons and saturated shades.

Here’s how to create designs with CMYK:

  1. When you start designing, choose the CMYK color space.

The settings for switching to this color space is different for each design software. I suggest you do a quick Google search—”switching to CMYK in [the program you use]”.

  1. When you finish designing, save your work in the RGB color space.

For the best possible color accuracy for your design, convert the file to sRGB color profile, sRGB IEC61966-2.1 to be exact. Most editing programs have this color profile as default. If yours doesn’t, don’t worry—the regular RGB color space will also work.

Order product samples

Getting your own product samples is a must to assure your designs come out great. It’s an investment that lets you check design placement and color, and overall product quality. Plus, you can use samples for creating top-notch product photos and videos, or use them in giveaways.

How to order product samples:

  1. Log into your Printful Dashboard
  2. Click New Order, choose your store, and click Sample order
  3. Choose your products and place an order

You can place 1 sample order per month, with a maximum of 3 items when you sign up with Printful. When you complete other milestones, like reach a certain threshold in accumulated sales, you get more sample orders. Read more about Printful’s sample orders.

Order Printful color swatches

Our color swatches have RGB color values next to them so you can use those when you choose the color for your designs.

You can order these color examples as sample orders too! Here’s how to order Printful color swatches:

  1. Log into your Printful Dashboard.
  2. Click New Order, choose your store and click Sample order.
  3. Choose the products you want to test out with Printful color swatches and complete the order.

To make sure the RGB values on the color swatches are easy to read, go for products with 12×16 inch print areas. Color swatches are available for the following Printful products:

Create and order your own custom color swatches

By creating your own color swatches, you can test only the colors you plan to design with.  If your designs or brand colors are monotone, wonderful—prepare a design file with all the colors of gray, red, pink, yellow—whatever! And once you check those colors, you won’t have to test each and every design you create with them.

Here’s how to create custom color swatches:

  1. Choose the product you’ll test your color swatches on and check the product’s recommended file dimensions.
  2. Open the design software you use and start a new design with your product’s recommended file dimensions.
  3. Draw whichever shapes you like, fill them in with your chosen colors and add their color values.
  4. Save your design file in the RGB color space and choose the .png file format.

And you’re done! Upload your custom color swatch on Printful and place a sample order with your design. Once you get your product, you can then decide which colors work and which don’t.

Here’s a custom color swatch our designers created (they offer graphic design services too!). Our designers tested particular RGB color values and went with this weird shape because why not.

And here’s how the custom swatch printed out. We chose to print on the Bella + Canvas 3001 t-shirt in Soft Cream.

      Hey Shiran,
      I took a look at the designs you shared, they’ll print out just fine! Generally, designs with gradients keep their colors when printed with our DTG method. One thing to keep in mind while designing—darker tones in designs might print out a bit darker and have a “flatter look”. Hope that helps!

  1. Aram

    Hello, Where can I find the file for the phone case color charts, I am trying to find it in the printful website. However, I only found the shirts color chart. Is there a link you can send me where I can download it please.

    Thank you so much for your help !

    1. Una Savcenko Post author

      Hi Aram! Currently, we have color swatch files for shirts only. If you want a color swatch file for phone cases, I’d suggest you create a custom one. You can read how to do that in this blog, section Create and order your own custom color swatches.

  2. Tom

    Hi there!

    Sorry if I’ve misinterpreted at all. If I upload my design to Printful in PNG and have used the sRGB IEC61966-2.1 colour theme from beginning to end of my design, should I worry about it coming out differently? I mistakenly ordered a sample shirt with a design on without reading this first!

    Many thanks,

    Nevada Sky Clothing

    1. Alise Zindiga

      Hey, Tom! You shouldn’t really worry about that too much. It’s possible that if you used really bright neon colors, they will look more faded, but that’s expected with digital printing.

      1. Tom

        I really appreciate that, it means a lot! I’ve gone back through and remade some designs in the CYMK colour profile using Photoshop, then changed it to the sRGB profile at the end of the design. We’ll see if that changes anything! Would this still come out okay? Please excuse all of my questions!

        1. Alise Zindiga

          I’m no expert myself and usually check such questions with my colleagues in the Design Team. What I understood from your previous comment is that you’ve already placed an order that was designed in the sRGB color profile, and my colleagues said that is should turn out fine. However, if you’re creating new designs in CYMK profile and then saving in sRGB profile it should work perfect. If ever in doubt, you can reach out to our Customer Support via [email protected] and share your print files.

    1. Daniela Bergmane

      Hey, Jason, I’m not too sure I’ve understood your question entirely correctly. Could you please explain it a bit more?

    2. Alise Zindiga

      Thanks for the clarification! The difference between 8 bits images and 16 bits images is the number of tones available for a given color—we only recommend using 8 bits.

  3. Emily

    Hi! I have designed something in Illustrator in the CMYK colour space, and now I want to colour correct my work using the Colour Matching Guide. Do I do this before or after saving my work in the RGB colour space? And when I do so, do I simply select each colour and input the RGB values as displayed on the guide?

    1. Alise Zindiga

      Hey, Emily, it’s great that you’ve created your design in CMYK colors, as it can help in avoiding gamut issues. From there, we suggest changing colors to sRGB color profile before saving the file. However, if you’re using our color swatches, it’s safe to work in sRGB color mode from the beginning, as all the color tones in our swatches are within the gamut.

    Does this apply to all printfuls items such as canvases, posters etc.?

    Would like to know regarding designs created in RGB that are to be printed for canvases and posters, must they be color-corrected to sRGB before uploading to printful or do you recommend something else? Thanks!

  5. Patrick

    Hi, colour accuracy is very important to me. I am wondering if you’ll be able to match Pantone colours (solid coated/uncoated)?

    1. Alise Zindiga

      Hey, Patrick! Our DTG printers work with an upgraded CMYK color space where we’ve added more ink colors, allowing us to achieve print colors that normally fall outside of the CMYK color range. The closest color space to our upgraded CMYK is the sRGB IEC61966-2.1 and that’s why we recommend it for print files to match the colors. Also, for better results, we suggest ordering our sample swatches.

    1. Daniela Bergmane

      I believe we do print the white underbase on non-white, light-colored garments, but it also depends on the design specifics. If you’d like for us to check and advise further, please feel free to reach out to our Customer Support by [email protected] and we’ll do so.

        1. Alise Zindiga

          Mockups are a close representation of the actual product. Although the result might look slightly different, we do print white color on all fabrics except white (even light pastel).

    would it be safe to say that as long as i start off my design using your provided templets i dont have to worry too much, assuming they are already configured to the correct color space according to the product that particular templet is downloaded for? thank you.

    1. Daniela Bergmane

      We always advise using our provided templates, especially when just starting out—that’s the easiest way to make sure that the end outcome is what you had in mind. Also, we suggest making sure that you’ve followed the file guidelines (you can also see them when clicking on the product in our catalog), as well as reading through this blog article. If all of this is done, generally, you should be good to go, but placing a sample order is always advised to check the quality prior to starting selling the product. 🙂

  7. Priharjanta

    Awesome,this article is very interesting. I’ve been working at printing industry for a couple years and your explains are true. But is still diffcult to deliver this information to our customers. We have a lot of customer with different background, experience, and understanding. We struggling and still work hard to give understanding about the color matching to our customer. Complains are comming in and out every single day.. LOL. But we never give up to educate them. Do have best practice, or simples method to educate your customer? nice sharing guys… thank you

    1. Daniela Bergmane

      Hey, thanks for the feedback. For you as a store owner, we always suggest carefully reading through this resource and taking it into account when working on your designs. When it comes to DTG printing, one of the factors that also plays an important role in the end outcome is the garment fabric. You can take a look at this article here to learn more about it: These two resources are great ones to learn more about the topic, understand the principles and factors that affect the end outcome and communicate it accordingly to your customers. However, if you and your customers ever receive a faulty product, please submit a problem report to us, and we’ll try to solve it for you.
