Have you ever printed a document and found the colour is different? The possible reason can be the difference between screen colours and print colours. Digital and print media are continuously evolving. Thus, it is essential to understand colour models such as CMYK. It makes the printed material look exactly as it appears on the screen. 

CMYK for printing is when you design a flyer, brochure, and business card it looks different on screen. However, how it turned out is an entirely different thing. It is because the CMYK colour spectrum looks different on screen. 

This guide will help you understand CMYK printing, how it works, and the printing process. By the end of this article, you will understand the application of CMYK and how you convert CMYK for printing. 

What is CMYK?

Before we understand CMYK, let’s understand the acronym: 

  • C for Cyan 
  • M for Magenta 
  • Y for Yellow 
  • K for Key (Black) 

CMYK colour model is a subtractive colour model different from the additive model used by screens. This model works by layering inks on a CMYK paper. The subtractive system begins with 

  • White paper that reflects all the lights
  • When inks are printed on paper, each subtracts colours of light and reflects other  
  • These four inks make a range of colours. 

How CMYK colour Printing Works

Now, let’s take a look at how CMYK colour printing works. Each colour in the CMYK colour spectrum plays a significant role: 

  • Cyan – greenish blue colour absorbs red light and reflects blue and green light
  • Magenta – reddish-purple colour absorbs green light and reflects red and blue light
  • Yellow – absorbs blue light and reflects red and green light
  • Black (Key) – absorbs colour and produces dark shades to create contrast print. 

These colours are mixed in varied percentages so the printer can create a range of colours. However, when compared to the RGB colour models, they have limited capacity to produce full-spectrum visible to the human eye. While RGB generates brighter colors, CMYK relies on constrained ink tones used in printing, which is crucial for making custom boxes.

 

Why is CMYK Important for Printing?

You may have noticed that printed documents for custom packaging sometimes don’t look as expected. It is because light works differently on RGB and inks interact differently on paper CMYK. in addition, the CMYK for printing accurately reproduces colour in the physical world. 

CMYK colour printing paper is used to create the final appearance of your design. Thus, the CMYK paper can print different colours in different types of paper including paper, glossy, matte, and absorb ink.

How Do I Convert to CMYK for Printing?

CMYK for printing is easy if you are working on Adobe Illustrator, Photoshop, or InDesign. To convert CMYK follow the steps below: 

Create a New Document with CMYK Settings: Begin a new project and set the document’s colour mode to CMYK. It ensures colour ensures optimized printing from the start. 

Convert RGB to CMYK in Existing Files: Convert your file to CMYK if designed in RGB. 

Adjust colours After Conversion: After converting to CMYK, you will notice a slight colour change. Always review and adjust colours specifically if you are working with brand-specific colours. Design programs have default fine-tuned colour options after conversion. 

Use Soft Proofing Tools: Design tools have soft proofing features to stimulate how colour will look in CMYK paper print.

Use the colour Picker Tool: use colour properties from the colour picker tool. CMYK represents colours in percentages of Black, Yellow, Magenta, and Cyan. 

Look for colour Profiles: always make sure the profile is set to CMYK for printing. Especially if you are printing from a commercial printer.
