Abstract

See full text

In an example, a surface inspection apparatus includes a light source to illuminate a portion of a surface in a print apparatus, a light detection apparatus and processing circuitry. The light detection apparatus may receive diffusely reflected light and specularly reflected light from the portion of the surface, and may comprise a detection element for detecting the specularly reflected light. The processing circuitry may comprise a comparison module to determine a relationship between an intensity of the detected diffusely reflected light and the detected specularly reflected light and a quality module to evaluate if the surface meets a quality criterion based on the relationship.
