Ensuring Tablet Logo Legibility: A Critical Step In Preventing Medication Errors

Unique debossing for tablets is crucial for medication identification and error prevention, as regulated by FDA guidelines (21 CFR Part 206). Key design factors for legibility include font choice, scale, and clarity. Sans-serif fonts with open peninsulas and large islands improve recognition and prevent issues like “picking” during manufacturing. Tablets with fewer, larger characters are generally easier to read, and light-colored tablets enhance contrast and visibility. Shadow depth, shaped by stroke angle and width, enhances readability.

Debossed angles between 30°-40° balance contrast with manufacturing ease; deeper strokes improve visibility, especially on non-film-coated tablets. Film-coated tablets, however, require optimized stroke depths to prevent illegibility due to coating thickness, calculated by tablet weight and density.

For high-contrast, cost-effective designs, manufacturers should consider factors like stroke width, depth, and radius to maintain legibility while preventing picking.
