From Halopedia, the Halo wiki
A jetbrush is a piece of Forerunner technology. When used in conjunction with certain smart-pigments, it can be used to automatically paint on a glass easel.
In approximately 97,745 BCE, a jetbrush used by Soma on Seaward picked up an image of an incoming Flood presence. This image was triangulated with two other devices and sent to the Prelate, who then reported it to the Auditor.
