Participants will compare questioned latent prints with sets of inked known prints.

Sample Description: A digitally downloadable .tif file of 10 latent prints with four sets of inked exemplar prints at 1000 dpi resolution. The latent prints may consist of any part of the hand, palms to tips. Due to large file sizes, advanced photo image software may be required to open and view these images. With tests consisting of digital test materials, participants are not limited to only on-screen comparisons and may use any other method; however, due to differences in printing technology, CTS cannot guarantee the quality of images printed from digital media.

On-Demand samples are randomized, and each test may contain a different combination of samples. Results can be returned to CTS until 30 June of the following year for which a test was purchased (e.g. a test purchased for 2025 will have a due date of 30 June 2026). Upon submission, an Individual Report will be automatically logged to the Individual Report Library and provided to the primary contact on file via email.

Samples for current-year tests ship within two business days after payment is received and processed. Tests for next year will ship at the beginning of that year or within two business days after payment is received and processed, whichever date is later.

Additional Information: Digitally downloadable test materials, as well as response forms for all test formats, are only available on www.cts-portal.com. The information necessary to access the test materials will be provided via email to the primary contact on file on the day of the test release.

This test is included on CTS' Scope of Accreditation to ISO/IEC 17043.
