Colour calibration for Sublimation printing

Sublimation printing is known for producing vivid, durable designs on polyester fabrics and polymer-coated items. However, achieving accurate, consistent colours requires more than just high-quality inks and the right blank substrates.

Colour calibration is a critical but often overlooked step that ensures the colours on your screen match the final print. Below, we’ll explain why calibration matters, the tools required, and how West Rand Sublimation Supplies can help you achieve optimal results.


 

1. Why Colour Calibration Matters

In sublimation printing, specialised inks are transferred from paper to substrate using heat and pressure. During this transformation, the colour profile can shift if not accurately controlled.

Without proper calibration, you risk:

  • Inconsistent Results: Different jobs may produce varying colours for the same design.
  • Waste of Materials: Incorrect colours lead to reprints, driving up costs in ink, transfer paper, and blank substrates.
  • Unhappy Clients: Poorly matched colours can hurt your professional reputation and client satisfaction.

Tip: Proper calibration helps you save time and money by reducing guesswork and ensuring repeatable, accurate colour output.

 

2. Tools and Software Needed

Achieving accurate colours involves several elements working together.

Below are the main components you’ll need:

  • ICC Profiles:
    ICC (International Color Consortium) profiles are tailored to specific printer models, ink sets, and paper types. They tell your design software (e.g., Adobe Photoshop) how to interpret and adjust colours for the best possible print match.
  • Calibration Device (Colorimeter or Spectrophotometer):
    These hardware tools measure colour output on your screen and printer, enabling you to create or refine ICC profiles. Although some users rely on pre-made profiles, custom profiling can significantly improve accuracy.
  • Design Software with Colour Management:
    Applications like Photoshop or CorelDRAW and Affinity allow you to apply ICC profiles and soft-proof your designs before printing. Ensure that your software supports colour management and that you’ve set up your working colour space correctly (e.g., sRGB or Adobe RGB).
  • Monitor Calibration Software:
    Calibrating your computer monitor is as vital as calibrating your printer. If your monitor inaccurately displays colours, no printer profile can compensate for that discrepancy.

 

3. Step-by-Step Guide to Colour Calibration

  1. Calibrate Your Monitor:
    Use a hardware calibration device to measure your screen’s output and generate a new ICC profile for your monitor. Apply this profile in your operating system’s display settings.
  2. Obtain or Create a Printer ICC Profile:
    Many printers come with default profiles, but for sublimation, you may need a specialised ICC profile. You can also create a custom profile using a colour measurement device and calibration software, ensuring more precise colours.
  3. Configure Your Design Software:
    In Photoshop or a similar program, select the printer profile under “Colour Settings” or “Print Settings.” Make sure to disable any conflicting colour management in your printer driver to avoid double profiling.
  4. Print a Test Chart:
    Print a colour test chart or swatch sheet to verify accuracy. Check for any discrepancies between the intended colours and the printed ones. Adjust your settings if needed.
  5. Soft-Proof and Final Adjustments:
    Most professional design software includes a “Soft Proof” feature to preview how colours will look once printed. Tweak colour or brightness until you’re satisfied with the proof. Then, proceed to final printing.

 

4. Common Challenges and How to Overcome Them

  • Changing Inks or Papers: When you switch to a different brand or type of sublimation ink or paper, you may need a new ICC profile to maintain consistent colour results.
  • Environment and Humidity: Sublimation inks can react to high humidity or fluctuating temperatures. Store them properly, and keep your workspace climate-controlled for consistent results.
  • Printer Maintenance: Clogged nozzles or outdated firmware can negatively impact colour accuracy. Perform regular maintenance tasks like nozzle checks and cleaning cycles.
