Which statement about stencil ink colors is true for serviceable slings?

• A. Black ink is used only
• B. Blue ink is used only
• C. White ink is used only
• D. Black or blue ink are used for stenciling

Answer: (D)

Stencil markings on serviceable slings must stay legible under field conditions, so the ink color chosen needs to stand out against the sling material and resist fading. In practice, inspectors use either black or blue ink for stenciling. Black works well on lighter fabrics, while blue provides strong visibility on darker or tan materials and generally holds up well with wear. White ink isn’t standard because it often doesn’t provide reliable contrast on many background colors and can wear off more quickly. So, using black or blue ink covers the common scenarios encountered with serviceable slings.
