What procedure is used to predetermine the quality of results when developing latent prints with powder?

The procedure used to predetermine the quality of results when developing latent prints with powder is a test print. Test prints are created as a benchmark to assess how well a specific method, such as powder development, works on various surfaces. By comparing the developed latent prints to the test prints, examiners can gauge the effectiveness of the development process and determine if the method provides clear and usable prints.

Test prints allow examiners to evaluate the consistency and quality of the results they can expect when working with actual latent prints found at crime scenes. This helps in establishing a standard for what constitutes a good-quality latent print and enhances the reliability of forensic analysis.

Control prints, sample prints, and reference prints serve different purposes in forensic examinations, such as establishing baselines or identifying known prints, but they do not specifically provide a means to assess the effectiveness of a method like developing latent prints with powder as directly as test prints do.
