Calibration Process and its importance for successful colour management
Have you been in a position of not getting the colour results you want? Do you have often colour arguments with your clients?
As fascinating field as colour is, you will agree that most of the times it is complicated to achieve the right colour. As you might already know, many factors influence the colour. To ensure colour consistency in your production line, you need firstly to communicate colour with accuracy.
We have noticed designer teams have a challenge in choosing and communicating colours in their designs as colour is presented differently from device to device and even between monitors of the same brand. The client’s view of the colour may be significantly different than what the designer sees in the monitor.

This problem causes misunderstanding and miscommunications among designers, technical teams, and the clients, as the colour cannot be defined correctly in the first place. Adjusting the given colour values is not a solution because it can create much more confusion to your client.
Another challenge is that colour is rarely reproduced exactly on the final materials (paper, textile, or Plastic) as it is shown on the monitor. Additionally, the same colour rarely looks the same in different textures.
One step closer to colour consistency in your process can be achieved with the calibration of your monitor or devices. Designers and manufacturers can save time with using a calibration process and resolve frustrations with their customers provided the customer also views on a calibrated device so that everyone sees the same colour.
Why do you need calibration?
Calibration is the process of adjusting the colour measuring instrument or the monitor to ensure consistency and accuracy of result every time the same colour is measured or viewed. You need to be sure that everyone collaborating sees what you are seeing.
There is such a huge range of different devices on the market with different levels of sophistication and settings that without calibration we cannot be certain about how a colour will be reproduced.
Just as your TV screen can be adjusted in terms of brightness and saturation so can monitors, laptops, tablets and phone screens and people will adjust them to their personal circumstances such as the brightness of the ambient lighting, their eyesight or the size of any text. All these will change the appearance of colour even further away from the original.
Calibration will ensure consistency with colour from device to device, from your camera, phone, tablet, laptop and monitor to scanner and printer.
You can calibrate all your devices to ensure that you look at the correct colour each time. Calibration should be an essential part of the colour measurement process too and it is recommended at least once per day. Investing in a calibration tool is crucial, as it offers objective colour results which are not based on an individual’s perception of colour.
Calibration for designers
The calibration process is important at the colour specification stage where the colour targets are determined. Designers should ensure that the defined colour in the design file originates from a calibrated monitor and correct colour standard data to enable it to remain the same and consistent during the entire process.
There are many options of calibrating your monitor with online tools or even with Windows and macOS providing tools for manual calibration, adjusting the colour gamut, brightness, and contrast.
However, if colour is an important asset for your business then you should look for greater colour precision and control and invest money to a professional calibration tool for design success.
Pantone’s calibration tool i1Studio Designer will help you calibrate multiple devices (monitors, laptops, phones & printers) with accuracy, allowing you to export the colour palettes directly to your design tools.
You need to warm up your monitor by opening it at least 30 minutes before the calibration process.

Note: Your colour inspiration can be accurately captured and transferred to your design software by using a Pantone Color match Card when photographing your colour target and Pantone Connect will provide the colour values for the Pantone libraries to your Adobe programmes.
Calibration for manufacturers
The accuracy of your colour measurement device is dependent on the right calibration process. Even the most precise colour measurement device, such as VeriVide's DigiEye system or any spectrophotometer, needs calibration to provide accurate colour results each time.
At the pre-production and production stage, colour technologists, quality assurance managers or production managers should calibrate the colour measurement device ideally every 8 hours or in every shift.
Regular calibration leads to the optimal performance of the device. With the calibration process, manufacturers and suppliers are ensuring that the colour submissions will be measured with a high level of accuracy, providing the right colour data which ultimately affects the production workflow.
If the colour is also going to be visually checked and compared against the original design or colour standard on-screen then the monitors must be calibrated. The monitors recommended by VeriVide for use with DigiEye systems have a built-in calibrator which performs a regular calibration every 6 hours.
For the DigiEye system, we recommend a 10-20 minutes warm-up before the calibration process.
With DigiEye the calibration of the camera and monitor ensures colour can be accurately viewed, assessed and measured on the actual materials and textures used enabling all parties in the supply chain to specify and approve the colour of the product.
