It can be frustrating to invest significant time designing a document only to discover that the printed colours don’t match your expectations. This issue often stems from different printers utilising varying information and interpreting data differently.
Whether you’re a designer or a design recipient, it’s crucial to understand the distinctions between RGB and CMYK colour modes to plan and optimise each stage of the design process.
The disparity between RGB and CMYK goes beyond simply knowing the letters’ colour representations. It’s about determining the most suitable colour space for your project. One colour mode will always yield better outcomes depending on where and how the final result will be displayed.
Both CMYK and RGB are colour-mixing modes commonly used in graphic design. In brief, RGB is ideal for digital work, such as what you see on screens, while CMYK is more suitable for printed products. However, comprehending the mechanics behind each mode is crucial to optimising your designs and understanding why the colours displayed on your screen may not perfectly match the print colours on the final product.
Choosing the Best Colour: RGB or CMYK
For years, commercial printers have recommended graphic designers convert RGB files to CMYK before sending them for print. This was done to ensure that designers could see an accurate representation of how their colours would appear, considering the difference between bright RGB on computer monitors and the CMYK colour model used in printing. However, recent advancements in printing workflows and commercial digital printing have made this conversion step unnecessary.
Modern printing workflows now even prefer RGB files. The concept of RGB (red, green, blue) is widely known, as it involves mixing these primary colours in different proportions to produce a wide range of colours. On the other hand, CMYK (cyan, magenta, yellow, black) works by subtracting or removing reflected colours from paper to create different shades. While CMYK is the standard for printers, RGB offers a larger gamut of colours.
In the past, designers would convert colours to CMYK to ensure better representation on computer screens and avoid disappointment when the printed piece looked different from the on-screen design. However, modern printing workflows allow printers to use colour profiles that automatically match CMYK inks to RGB values, resulting in more accurate and consistent results. Furthermore, commercial digital printers have expanded their ink options beyond CMYK to match the wider colour gamut of RGB.
This shift in approach benefits designers in several ways. RGB files are smaller and easier to handle, making them more convenient for transferring and storing. By keeping files in RGB, designers have greater flexibility since they often work on projects intended for both print and digital mediums.
What Is the Difference Between RGB vs CMYK?
Colour choice is very important in the field of graphic design. RGB and CMYK are two widely used colour models in this area. Digital projects typically use the more flexible RGB colour mode, but printed materials require the more limited CMYK. Understanding how RGB and CMYK work will help you create better designs. Let us explore these colour models in greater detail.
What is RGB?
A three-colour technique, RGB (red, green, and blue) is most commonly seen on desktop computer screens.
Applications of RGB
We’ve already established that digital displays benefit greatly from the RGB colour option. This is because digital screens generate light of varying colours to get the desired tones. Therefore, the RGB colour mode is almost certainly being used to create the colours you see on your computer screen, TV screen, or other digital display.
The following examples highlight when it is best to use the RGB colour mode in a marketing or digital design context:
- Making a Website Logo for Your Store
- Creating infographics and icons for social networks
- Making graphics for blog posts.
- Crafting eye-catching subject lines for electronic messages
- Displaying virtual prototypes of your wares on your website
File Formats for RGB
Use either the.jpg or.png format when working with photos for the web or digital design. In addition to being viewable on many different devices, these files can also use the RGB colour space.
What is CMYK?
The CMYK colour model is a four-color printing technique that uses cyan, magenta, yellow, and key (black) in that order to produce true colours in printed items.
Applications of CMYK
Use the CMYK colour mode for the following types of graphic design work:
- Business cards
- Brochures
- Magazines
- Posters
- T-shirts
- Tote bags, mugs, and hats
- Almost any other item that requires printing
File Formats for CMYK
Files saved in PDF, TIFF, or EPS formats tend to print the best. These file types are compatible with the CMYK colour space and ensure high-quality output from your printer.
Choosing the Right Colour Mode
The choice between RGB and CMYK requires careful consideration of a number of parameters. First, CMYK guarantees a high degree of similarity between the printed product and the digital preview. Colour shifts are possible when converting RGB files to CMYK for printing on four-color printers. These variations are typically inconsequential, but they might cause problems in situations when colour accuracy is essential. Similar colour shifts can occur when posting a CMYK image online.
File Types and Specifications
PNG File Type:
- Allows for both RGB and sRGB colour spaces
- enables see-through backgrounds
- Useful as a fabric and in other contexts
JPEG File Type:
- Compatibility with a wide range of colour spaces
- Does not allow for see-through backgrounds
- Useful in many contexts, regardless of whether or not the underlying surface is see-through
PNG is the prefered format for garments and other things that call for a transparent background. PNG does not work with the CMYK colour space, unfortunately. However, this restriction can be bypassed by creating the image in CMYK colour mode, which guarantees that the whole gamut of CMYK hues is faithfully represented. As a result, there could be some variation between what you see on screen and what you get in print.
Companies that specialise in printing also accept files in the RGB format. The native raster image process (RIP) of the printing device transforms a PNG file’s RGB colour profile into a CMYK colour profile in preparation for printing.
Common Mistakes to Avoid
Designers who can tell the difference between RGB and CMYK will have an advantage. However, even seasoned designers can make blunders when it comes to choosing RGB or CMYK. The following are some pitfalls that are easy to slip into:
- Not checking your work for errors: Maintaining a professional image requires proofreading for typos, grammatical errors, and flaws in your design.
- Miscommunication with your printing service: It’s important to let the printing business know the specifics of your design, such as the file format and colour style (RGB or CMYK). This helps them guarantee reliable printouts.
- Printing from an RGB file requires converting it to CMYK prior to submission: failing to do so will result in undesirable printouts.
Colour Printing Tip: Converting RGB to CMYK
Checking your program’s settings is essential for producing professional-looking printed materials like brochures and flyers. To get the best results when printing, change the colour mode from RGB to CMYK as soon as feasible in the design process.
Designers can improve the quality and precision of their work by familiarising themselves with the differences between RGB and CMYK and avoiding frequent mistakes.
How to Get Bright Print Colors With CMYK?
Regrettably, reproducing a computer screen’s vibrant and saturated colours onto physical products is not always achievable. When converting colours from RGB to CMYK, the brightness of the colours tends to diminish in print. The most intense colours attainable using the CMYK colour model are solids, specifically when using 100% cyan, magenta, and yellow.
However, it is important to note that these colours will appear less brightly in print than on-screen. The RGB colour model offers a much broader range of shades than CMYK. Additionally, the illuminated nature of a screen creates more brilliance in colours than any pigment on canvas or other materials can replicate. Nevertheless, certain materials like PU leather may provide a more vivid outcome than a cotton hoodie. The physics of different materials influence these variations in colour brightness, and while they may appear slightly duller in print, they still offer their unique appeal.
The CMYK colour model can be used if you desire bright and solid colours. For instance, combining 100% cyan and 100% yellow produces a vibrant green. However, if your definition of “bright” does not necessarily entail “saturated,” you may need to adjust or tint those colours accordingly. It is worth noting that process colours (CMYK) are less effective in achieving such adjustments. These limitations are inherent to the process of colours used in printing.
Designing Print Collateral
Step back and think about what colour space you’re working in when making your document. Most likely, you’ll be working in the RGB colour space. We can set the raster image processor (RIP) for the colour space profile on higher-end printing systems based on your input source. To ensure that your file’s original colour intentions are preserved while being converted to the appropriate CMYK output profile, we can set the RIP to RGB.
Because of this, the desktop and high-end printers will likely have very different colours. Once you’ve changed your formula to get the exact desired results on the better printer and saved your settings, you’ll always get the colour you want.
You should change a few things to get the desired results when you print. For example, you may need help setting up your monitor to work with your printer. It’s important to start with realistic goals and to know how colour management and colour translations between different colour spaces work in digital printing. Having a consistent colour management system will help you get the desired results when printing in colour, no matter how big or small.
Conclusion
If you want your design process and final product to be as efficient and effective as possible, you need to decide between the RGB and CMYK colour modes. Unlike CMYK, which is more suited for printed products, RGB is better suited for digital work, such as what you see on displays. To get the most out of your designs and to comprehend why the colours you see on your screen do not always correspond to the colours you print, it is essential to have a firm grasp of the physics underlying each mode.
Before transferring files for printing, commercial printers have long suggested that graphic designers change the colour mode of their files from RGB to CMYK. This transformation is no longer essential because of developments in printing operations and commercial digital printing. RGB files, which can represent a wider range of colours, are currently the standard in today’s printing procedures. This new strategy is advantageous to designers in a number of ways, including the fact that their creations are more portable and less cumbersome to store.
Uses for the three-colour RGB approach include making logos, infographics, and icons for websites, social media, blog posts, electronic messages, and exhibiting virtual prototypes online. The RGB colour space supports the widely-supported.jpg and.png file formats. Printing in CMYK uses cyan, magenta, yellow, and key (black) to create accurate colours on paper.
There are several factors to think about while deciding on a colour mode. CMYK is preferable for graphic design projects because it ensures a high degree of similarity between the printed result and the digital preview. Converting RGB files to CMYK for use with four-colour printers can cause noticeable colour shifts. While usually unnoticeable, these differences might be problematic when spot-on colour reproduction is required. Both JPEG and PNG support a broad variety of colour spaces, with the former accommodating both RGB and sRGB.
While PNG is the format of choice for clothing and translucent backdrops, it is incompatible with the CMYK colour scheme. To avoid this, be sure to use the CMYK colour mode when creating the image, as it accurately depicts the complete range of CMYK colours.
Understanding the differences between RGB and CMYK will help designers avoid frequent pitfalls and create better designs. Maintaining a respectable reputation requires regular proofreading to catch typos, grammatical errors, and other problems. Reliable prints also necessitate proper miscommunication with the printing service.
If you want your printed materials to have vivid colours, you should switch the program’s colour mode from RGB to CMYK as soon as feasible. Your output will gain in both quality and accuracy as a result of this. In the CMYK colour space, solid hues made with 100% cyan, magenta, and yellow are the most saturated you can get. However, the printed version may not be as vivid as the digital version.
When designing print materials, it is important to think about the colour space you’ll be printing in, set the raster image processor (RIP) for the colour space profile on high-end printing systems based on your input source, and then save those changes. In this way, you can rest assured that your printed output will always meet your expectations.

Frequently Asked Questions About Printer Ink
Does CMYK look like RGB when printed?
RGB is used in electronic devices, like computer monitors, while printing uses CMYK. When RGB is converted to CMYK, colours can look muted. Designers were often disappointed when their printed pieces looked different from what they had seen on screen.
Which colour mode is used for the highest-quality print?
Monitors use RGB, whereas printers use CMYK. This means RGB colour mode is best for digital designs, while CMYK is best for print materials. You can switch your colour guide to CMYK, but it needs to accurately represent your printed product, as the colours can depend on the printer.
Does CMYK look brighter when printed?
Unlike a screen image, the brightness of a colour is created by adding additional ink to a solid white substrate rather than changing the intensity of light shining through a pixel. This means a CMYK print can only ever be as bright as the printed paper.
What colours are hard to print in CMYK?
In CMYK, blue is one of the most challenging colours to reproduce accurately. We suggest you use even and balanced mixtures, like 100-50-0-0. Otherwise, the result will be a purple or green colour.
Is 600 or 300 DPI better for print quality?
Generally, 300 DPI is great for small prints, while 600 DPI is amazing for large prints. If you’re scanning documents or photos to be used on the web or in emails, 300 dpi is more than enough. If you want to print large photos or blow them up to poster size, 600 dpi will give you better results.
