You can implement this by using advanced RIP software, such as Cadlink Digital Factory or Wasatch RIP, which features tools to analyze file transparency and define specific white layering zones. Alternatively, for higher precision, you can manually create a grayscale mask in design software like Adobe Photoshop or Illustrator and save it as a dedicated spot channel.

White ink contains heavy titanium dioxide pigment that is notoriously prone to settling. You should monitor your white ink lines weekly for sediment buildup; if you notice pigment collecting on the tubing walls, a system flush is required immediately to prevent permanent blockages.

Extended-gamut ink sets, which add extra channels like orange, green, or red, allow for neon hues and specific Pantone colors that are difficult to achieve with standard CMYK. However, their performance varies significantly by manufacturer, and it is highly recommended that you test samples before deciding if the extra cost and complexity are justified for your specific production needs.

A white ink underbase is essential for printing vibrant colors on dark-colored garments. Standard sublimation printers lack a white ink channel and the necessary agitation system required to keep white pigment-based ink from settling and clogging the printhead.
