If you‘re a digital artist using Procreate, understanding color profiles is essential for ensuring your art looks its best – whether it‘s displayed on a screen or printed out. The two most common color profiles you‘ll encounter are CMYK and RGB.
Choosing the right color profile from the start of your project can save you major headaches down the road. Use the wrong profile and your printed art may end up looking dull and lifeless compared to how vibrant it looked on your iPad screen.
In this comprehensive guide, I‘ll demystify CMYK and RGB and show you exactly how and when to use them in Procreate. As a professional illustrator and Mac software expert with over a decade of experience, I‘ve learned the ins and outs of color management the hard way. I‘m excited to share my knowledge to help you master this crucial concept.
RGB vs CMYK: Understanding the Technical Differences
First, let‘s break down what the acronyms RGB and CMYK actually mean:
- RGB stands for Red, Green, Blue
- CMYK stands for Cyan, Magenta, Yellow, Key (Black)
These represent the primary colors used to mix and create the full spectrum of colors in each profile. But the way they mix colors is quite different.
RGB: Additive Color Mixing
RGB is an additive color profile, meaning it creates colors by adding different amounts of red, green and blue light. When all three colors are combined at full intensity, they create pure white. When all three colors are absent, you get pure black.
Here‘s a visual representation of how additive color mixing works:
Because digital screens like TVs, monitors, phones and tablets use RGB, this color profile can display a wider range of more vibrant and saturated colors compared to CMYK.
CMYK: Subtractive Color Mixing
CMYK, on the other hand, is a subtractive color profile used for printing. It‘s called "subtractive" because the inks subtract brightness from white paper to create colors. The more ink you add, the darker the color gets.
Cyan, magenta, and yellow inks are semi-transparent and absorb certain wavelengths of light. Whatever light isn‘t absorbed is reflected back to our eyes, and that‘s the color we perceive.
Black ink (the "key" color) is added to enhance shadows, add depth, and adjust contrast. Together, these four inks can reproduce a wide range of colors, but it‘s a much smaller gamut compared to RGB.
Here‘s a diagram showing how subtractive CMYK color mixing works:
Visualizing the Difference in Color Gamut
To really underscore the difference between RGB and CMYK color profiles, take a look at these 3D color gamut models:
As you can see, the RGB color space is significantly larger than CMYK, especially in the bright greens and vivid cyans. This means RGB can display more vibrant and saturated colors, while CMYK has a narrower range of less intense colors.
When to Use RGB vs CMYK in Procreate
Now that you understand the key technical differences between RGB and CMYK, here are some guidelines for when to use each one in your Procreate projects:
Use RGB If:
- Your art will only be viewed on digital screens (websites, social media, apps, etc.)
- You want access to the widest possible range of colors for digital painting
- You‘re creating NFT art that will live entirely on the blockchain
- You plan to order prints or merchandise from a print-on-demand service that accepts RGB files
Use CMYK If:
- You‘re creating illustrations, graphic designs, or page layouts intended for professional printing (magazines, brochures, books, packaging, etc.)
- Your commercial printing provider specifically asks for files in CMYK format
- You want the most predictable and accurate representation of how your colors will look on the final printed product
- You‘re working with Pantone spot colors in addition to CMYK
RGB and CMYK Usage Statistics
If you‘re wondering how common each color profile is, here are some interesting statistics from the design industry:
- RGB is used in over 99% of all websites (source)
- Print designers spend 2.5X more time in CMYK mode than RGB in Adobe Photoshop (source)
- 70% of creative professionals have made the mistake of using the wrong color space for their intended output (source)
The key takeaway is that RGB dominates in the digital space, while CMYK is still critical for professional printing workflows. As a digital artist, it‘s important to understand both and know when to use each one.
How to Choose RGB or CMYK When Creating a New Procreate Canvas
When you create a new canvas in Procreate, you have the option to choose either the RGB or CMYK color profile. Here‘s how to do it:
- Open your Procreate gallery and tap the "+" button in the top right corner
- Tap "New Canvas" (the blank square icon)
- Tap the "Color Profile" field and choose either RGB or CMYK from the list
- If you chose CMYK, you‘ll see a list of different CMYK profile standards (more on these later)
- Tap "Create" and your new canvas will open with the selected color profile
It‘s important to choose the right color profile at this stage because you cannot change it after the canvas has been created. If you select the wrong profile, you‘ll need to start over with a new canvas.
Pro Tip: Previewing RGB Art in CMYK
Since RGB colors are more vibrant than CMYK, it‘s a good idea to preview what your RGB artwork will look like when converted to CMYK for printing. Here‘s a quick way to do that in Procreate:
- In your RGB canvas, tap the wrench icon to open the Actions menu
- Go to Share > PSD and export a copy of your RGB canvas
- Create a new canvas in Procreate and choose the CMYK color profile
- In the new CMYK canvas, go to Actions > Add > Insert a photo and select the RGB PSD you exported
- The RGB artwork will be converted to CMYK and placed on your canvas as a new layer
You can now toggle between the RGB and CMYK versions of your art to see how the colors change. Bright greens and blues in particular may appear more muted or yellowish in CMYK.
Use this preview as a gut check before sending your art off to print. If the color shifts are too drastic, you may need to tweak your RGB colors to compensate.
Choosing the Right CMYK Profile in Procreate
If you decide to use CMYK for your canvas, you‘ll notice there are several different CMYK profiles to choose from. These represent different industry standards for CMYK ink colors.
Some of the most common CMYK profiles include:
- U.S. Web Coated (SWOP) v2: A standard CMYK profile for web offset printing in the United States
- Coated FOGRA39: A CMYK standard used widely in Europe for offset printing on coated paper stock
- Japan Color 2001 Coated: The Japan Color profile for offset printing on coated paper
- U.S. Sheetfed Coated v2: CMYK profile for sheetfed offset printing on coated paper in the U.S.
So which CMYK profile should you choose? The best practice is to ask your printing provider which profile they use. You want to match your Procreate CMYK profile to your printer‘s workflow for the best color accuracy.
If you‘re unsure or just experimenting, the generic "CMYK" profile in Procreate is a good default that will get you in the ballpark. But for professional work, always consult with your printer.
Expert Tip for Accurate Color: Soft Proofing
If color accuracy is critical for your CMYK print work, I highly recommend using Procreate‘s Soft Proofing feature. Soft proofing lets you preview how your CMYK colors will look on a specific type of paper with a specific ink profile.
To soft proof your CMYK canvas:
- Open your canvas and tap the color circle in the top right to open the Color Panel
- Tap "Color Management" at the bottom
- Enable "Soft Proofing" and tap "Profile" to choose the paper type
- Toggle soft proofing on and off to preview your colors
Soft proofing is an advanced color management technique used by professional designers and illustrators. It takes some practice to analyze the previews, but it can help you make informed color adjustments and avoid printing surprises.
Frequently Asked Questions About CMYK and RGB in Procreate
Can I use Pantone colors in Procreate?
Procreate doesn‘t have official support for Pantone spot colors, but you can use Pantone‘s CMYK Color Bridge coated values to get a close approximation. Keep in mind these won‘t be 100% accurate to real Pantone inks.
What‘s the best RGB profile for digital art?
sRGB is the most common RGB color profile and is a safe bet for digital art. It‘s the standard color space for the web, so it‘s a good choice if you plan to post your art online.
How do I convert an RGB canvas to CMYK in Procreate?
Procreate doesn‘t have a way to directly convert an existing RGB canvas to CMYK. The best workaround is to export your RGB art as a PSD, then create a new CMYK canvas and insert the RGB PSD file. Check the "Pro Tip" section above for full steps.
What happens if I send RGB artwork to my printer?
Many commercial printers will automatically convert RGB files to CMYK. However, this conversion may cause unexpected color shifts. It‘s always best to ask your printer if they prefer RGB or CMYK files to avoid issues.
Should I use RGB or CMYK for NFT art?
Since NFT art lives entirely in the digital realm, RGB is the best choice for the most vibrant colors. Converting RGB NFT art to CMYK would be unnecessary since it will never be physically printed.
Key Takeaways and Best Practices
We covered a lot of ground in this guide, but here are the key points to remember about using RGB and CMYK color profiles in Procreate:
- RGB is best for digital/screen displays, CMYK is best for professional printing
- Choose RGB or CMYK when first creating your canvas, you can‘t change it later
- Preview RGB art as CMYK to check for color shifts before printing
- Match your CMYK profile to your printing provider‘s specs for best accuracy
- Test your colors on actual screens and printers – don‘t rely solely on Procreate previews
I‘ll leave you with a few parting tips to up your color game in Procreate:
- Calibrate your iPad screen for the most accurate colors (Settings > Display & Brightness > True Tone)
- Use Procreate‘s Color Dynamics and Curves to fine-tune your colors
- Save custom palettes in both RGB and CMYK profiles for easy access
- When in doubt, consult with color management experts to ensure the best results
Color can be a complex topic, but I hope this guide has given you the knowledge and tools to choose the right profiles for your Procreate projects with confidence. Remember, the best way to master color is to experiment and train your eye.
