What is a common purpose of a white print in welding?

A white print in welding serves primarily to present detailed weld symbols, which are essential for conveying specific information about how welds should be executed. These symbols provide welders with instructions regarding the type of weld required, the size, and any special processes that need to be followed. Having this information clearly outlined allows for accuracy and consistency in the welding work, ensuring that the final product meets design specifications and quality standards.

The other options do not align with the primary function of a white print. While providing a dark background or simplifying texture representation may be relevant in other contexts, they do not characterize the essential purpose of a white print in welding. Highlighting measurements, although important in design, is not typically the main focus of a white print compared to the detailed conveyance of weld symbols which guide the welder's actions directly.
