New API V3.0: Get our API at a special price. Get it now. Get more detailed color conversion results - perfect for web projects, plugins, internal tools or SaaS applications. Valid from 2025-10-21 up to and including 2025-11-21 (23:59 CET)
First enter the color code to find the conversion and the best matching colors. After that, you can create palettes by clicking on and download color samples.
If you need to print a Pantone® colour using process inks, you can convert from Pantone to CMYK. This translates a Pantone spot colour into the four-colour printing model: Cyan, Magenta, Yellow, and Black.
The Pantone-to-CMYK conversion is crucial for printers and designers working with standard offset or digital printing. qConv automatically calculates the best CMYK percentage values for accurate colour reproduction.
How it works
During the Pantone to CMYK conversion, the Pantone colour is converted to LAB values and then mapped to CMYK using ICC profiles for precise printing.
Example: Pantone 186 C ≈ cmyk(12%, 100%, 91%, 3%).
This Pantone-CMYK conversion ensures colour consistency across print materials and avoids expensive spot-colour printing.
Example & Use
Example: Pantone 485 C ≈ cmyk(0%, 95%, 100%, 0%). qConv instantly displays the conversion and ΔE difference.
Tip: Use Pantone to CMYK conversion when preparing files for four-colour printing to maintain brand accuracy.
* Note:
qConv.com searches for the next matching color from the selected color palette. In most cases, there will be minimal or apparent color differences because there is not an exact match for every color.
The Pantone® Matching System (PMS) is the world’s leading standardized color system, used across design, print, and manufacturing industries. It defines colors with unique numerical codes, ensuring that a color appears the same everywhere — regardless of the material or production method.
The classic Pantone® system includes 1,114 spot colors originally defined for offset printing. Each tone is identified by a specific code, such as “Pantone 485 C.” Over time, Pantone has expanded its library with systems like Pantone Plus and Extended Gamut, now covering more than 1,800 solid colors and over 2,600 shades for textiles and interiors.
Usage
Pantone® colors are the industry standard for print production, product design, and brand identity. By using standardized color formulas, designers and printers can communicate exact hues across materials and global supply chains. Pantone is indispensable for logos, packaging, and high-fidelity printing where precise color reproduction is critical.
In software like Adobe Illustrator, InDesign, or Photoshop, Pantone libraries can be accessed directly to select or convert colors for professional use. Pantone is also used in fashion, interior design, and digital color trend forecasting.
Tips for Designers & Brands
Always verify Pantone colors under proper lighting conditions — printed tones may appear different under daylight and LED illumination. For consistent branding, define Pantone references alongside RGB and CMYK values in your style guide.
With qConv, you can easily convert Pantone® colors to HEX, RGB, CMYK, RAL®, or HKS® equivalents, compare shades, and generate harmonious palettes for cross-media consistency.
The CMYK color model (Cyan, Magenta, Yellow, Key/Black) is the standard color space for professional four-color printing. It describes how colors are created by mixing printing inks on physical material - usually paper. In contrast to RGB, which adds light colors, CMYK works subtractively: the more color is applied, the less light is reflected - and the darker the result appears.
Each of the four colors can have a value between 0% and 100%. A high percentage value stands for high color coverage in the print. By combining these values, several trillion CMYK color tones can be generated - however, the displayable color gamut is lower than that of RGB, which is why conversions can lead to visible color deviations.
Use
The CMYK color system is the industry standard in printing - from magazines, catalogs and packaging to corporate designs. Every professional print shop works with CMYK color profiles (e.g. ISO Coated v2, FOGRA39) to ensure consistent and accurate color results. Designers should therefore convert their RGB or HEX colors to CMYK before approving them for printing in order to minimize colour deviations.
In digital design programs such as Adobe Photoshop, Illustrator or Affinity Designer, the CMYK color space can be selected directly as a working profile. This allows printing colors to be simulated exactly and checked visually at an early stage.
Tips for designers & agencies
When converting screen colors (RGB/HEX) to CMYK, note that particularly bright blue, green and neon tones appear duller in print. A soft proof preview helps to assess the color appearance. For corporate designs, use CMYK color values from verified brand guidelines or Pantone references to achieve consistent print results.
When working with qConv, you can convert any digital color to exact CMYK values in seconds, compare color deviations and even generate matching alternative palettes.
