What is the primary function of using black ink in certain documentation?

The primary function of using black ink in certain documentation is to comply with standard practices. In healthcare and administrative settings, specific conventions are established to ensure that records are created and maintained consistently and in a manner that meets regulatory and accreditation requirements. Using black ink is often a standard practice because it is legible, provides high contrast against white paper, and is widely accepted for official documents across various industries, including healthcare. This adherence to standards not only facilitates easier reading but also ensures that the documentation holds up under scrutiny in legal or regulatory reviews, reinforcing the integrity of the records.
