What could cause a ridge break in a friction ridge print?

A ridge break in a friction ridge print can occur due to various factors that disrupt the continuity of the ridges. This includes several phenomena that hinder the formation or preservation of the ridge pattern.

When considering the various causes, a dip in the ridge at a pore opening can indeed result in a ridge break, as it alters the smoothness and continuity of the ridge. Additionally, dirt particles can obstruct or interrupt the ridge pattern, leading to breaks. These interruptions can arise from various environmental factors that impact how prints are deposited, so failures in deposition can also be a significant factor contributing to ridge breaks.

Moreover, matrix failures, which refer to issues related to the medium that carries the print (like ink or other materials), can lead to breaks in the ridges as well. The various factors that impact latent print development and integrity make it clear that any disruption to the ridge pattern can result in a ridge break. Therefore, the most comprehensive answer includes all these possibilities, accounting for the different ways ridge breaks can manifest in friction ridge prints.
