Optimizing Printer Profiles: Colormunki Native Software vs. ArgyllCMS

X-Rite Colormunki Native Software

The X-Rite Colormunki software employs a straightforward two-step method to create printer profiles. Here's how it works:

1. Printing the Initial Target: The process begins with printing a target of 50 color patches.
2. Reading the Patches: Next, you read the patches using the Colormunki device. The software uses this information to calculate a second target.
3. Calculating the Final Profile: After printing and reading the second target, the software combines the measurements to produce the final printer profile.

While this method is relatively easy to follow and yields good results, it can be further optimized. One effective approach involves using a set of test images that cover a wide range of colors and tones. By including images with real-world scenes, out-of-gamut colors, greyscale gradients, and diverse skin tones, you can ensure the printer profile handles critical colors more accurately.

Optimizing X-Rite Colormunki Profiles

To optimize the profiles created with X-Rite Colormunki software:

• Use Diverse Test Images: Incorporate a variety of images, including landscapes, textured surfaces, and human faces from different ethnic groups. This helps the profile manage different color and tone challenges.
• Focus on Critical Colors: Pay special attention to grey tones, out-of-gamut colors, and skin tones. This ensures the profile can reproduce these colors accurately and perceptually.

ArgyllCMS: A More Advanced Approach

For those willing to invest more time and effort, ArgyllCMS offers a more advanced method of creating printer profiles. Although it requires using command-line tools, the results can be significantly better. Here’s a streamlined method for creating profiles with ArgyllCMS:

1. Select a Target Size: After experimenting with various target sizes, a 480-patch target has been found to offer excellent results. It strikes a balance between accuracy and practicality, as it fits on a single A4 sheet.
2. Print and Measure: Print the 480-patch target and measure it using the Colormunki device.
3. Generate the Profile: Use ArgyllCMS commands to process the measurements and create the final printer profile.

Benefits of ArgyllCMS

• Superior Black and White Rendition: The black and white output tends to be more neutral and less warm compared to the Colormunki profiles.
• Better Skin Tones: ArgyllCMS profiles often produce more accurate and pleasing skin tones.
• Gradual Greyscale Gradients: The transition from white to black is smoother and more gradual, providing a more natural look.

Practical Comparison

When comparing prints from an Epson 1500W printer using generic Dye CcMmYK ink:

• Colormunki Native Software: Produces good results with optimizations but may result in warmer black and white tones and slightly less accurate skin tones.
• ArgyllCMS: Achieves better neutrality in black and white images, improved skin tone accuracy, and smoother greyscale gradients.

Both the X-Rite Colormunki native software and ArgyllCMS have their strengths. The former offers ease of use with the potential for optimization, while the latter provides superior results for those willing to navigate its complexities. By choosing the method that best suits your needs, you can ensure your printed images are as accurate and vibrant as possible.
