LEX-32[BLD]SENSORY DESIGN

Substrate Bleed (Dot Gain)

/ˈsʌb.streɪt bliːd/

ETYMOLOGY

Latin substratum (under-layer) + Old English blēdan (to produce liquid)

COINED BY

Master Letterpress Guilds / Jan Tschichold

CANONICAL DEFINITION

The physical capillary wicking of liquid mineral ink into paper fiber; in digital typography, the optical softening applied to razor-sharp vector letterforms to evoke tactile presence.

OPERATIONAL PRACTICE

Sub-pixel font antialiasing filters and micro-diffusion blurs that soften harsh high-DPI contrast into comfortable reading textures.

“Sharpness is a mechanical triumph; warmth is a human requirement.”
