Data Structure
Digital exchange of color information between brands and suppliers relies on a standardized file type that carries spectral reflectance data. The qtx format is the industry standard for transmitting these measurements without the loss of detail associated with simple rgb or cmyk values. It allows a dyer in one country to see the exact spectral fingerprint of a standard selected by a designer in another.
Digital Communication
Files in this category include not only the reflectance numbers but also metadata about the illuminant and observer settings. Using the qtx format ensures that everyone in the supply chain is working from the same primary data. This eliminates the errors caused by shipping physical fabric swatches which can fade or get lost.
Software Compatibility
Most modern spectrophotometers and color formulation programs can export and import these files. The qtx format supports the building of digital color libraries that can be searched and updated instantly. It facilitates the rapid approval of lab dips by allowing for electronic submission.
The structure is based on plain text, which makes it easy for different systems to interpret the data correctly.
Supply Chain Transmission
Reliable data transfer reduces the lead time for new product development by several weeks. The format provides the secure link needed for global color management.
