spot variation

Definition: The change in size of a spot laid down by output device such as laser, ink-jet, dye sublimation printer when the spot reaches the support material e.g. paper, plastic film, fabric, etc. * Generally spot grows slightly in size as it spreads into the support (where it is also known as dot gain), but may get smaller e.g. on polished metal surface. * Spot variation with support material used must be adjusted for in order to maintain density and colour accuracy.
