Optimizing Colour Accuracy for Edible Printers

Optimizing Colour Accuracy for Edible Printers: A Guide for Enhanced Results

If you've recently purchased an edible printer and are facing challenges with colour accuracy, particularly when using wafer paper, you're not alone. Many users experience differences in colour reproduction, especially with constraints due to UK regulations on edible colour ingredients. Red tones, for example, can often appear less vibrant than expected. But worry not—there are effective strategies to enhance your printed results and achieve vibrant, accurate colours.

Understanding Colour Discrepancies

Edible printers use specific types of edible inks that are safe to consume but might not offer the same colour intensity as traditional, inedible inks on white printing paper. Additionally, the texture and absorbency of wafer paper can affect how colours are printed, resulting in less saturated and vibrant outputs.

Adjusting Your Colour Settings

One effective solution to mitigate these issues is to adjust your image settings before printing. Editing software like IrfanView, a user-friendly and free tool, can be particularly helpful. Here’s how to make the necessary adjustments to ensure better colour quality:

  1. Open your image: Launch IrfanView and open the image you intend to print.
  2. Access Colour Corrections: Navigate to the ‘Image’ menu and select ‘Colour Corrections’.
  3. Adjust Contrast and Saturation: Slide the ‘Contrast’ and ‘Saturation’ controls higher than you typically would. On your screen, colours should look significantly more vibrant and perhaps a bit over the top.
  4. Apply and Preview: Click ‘OK’ to apply your settings. It’s a good practice to print a small sample to check the output before proceeding with larger prints.

Why Over-Adjust on Screen?

It might seem counterintuitive to adjust the colours to look overly vibrant or exaggerated on your computer screen. However, due to the properties of edible inks and wafer paper, these exaggerated on-screen colours can translate into more accurate and visually appealing colours once printed. This adjustment compensates for the colour absorption discrepancies of wafer paper.

Further Tips and Support

Experiment with different levels of adjustments to find what works best for your specific printer and paper combination. Remember, each printer may react slightly differently, so what works for one might not work for another.

If you’re still struggling to get the colours just right, don't hesitate to reach out to customer support. They can provide guidance tailored to your printer model and the type of images you're working with.


While edible printing is a fantastic technology that opens up new creative possibilities, it does come with its set of challenges. By understanding these challenges and learning how to adjust your colour settings appropriately, you can greatly enhance the quality of your printed edible images. Happy printing!
