Which component comprises biologically safe dyes used for printing information or company logos on the exterior of tablets or capsules?

• A. Film Former/Coatings
• B. Printing Links
• C. Absorption
• D. Disintegrants

Answer: (B)

Printing inks are used to apply biologically safe dyes for printing information or logos on the exterior of tablets or capsules. These inks are formulated with colorants that are approved for contact with the product and safe if ingested in trace amounts, ensuring they don’t compromise patient safety or drug stability. They must adhere well to the tablet surface and withstand handling, moisture, and storage without affecting dissolution or efficacy. This purpose differentiates printing inks from film coatings, which protect or modify release, and from disintegration or absorption-related components, which serve different functions in the tablet.
