Brightness is a key quality measure in paper production that indicates how white and reflective paper appears to the human eye. When paper professionals talk about brightness, they're referring to how much blue light a paper reflects on a scale of 1 to 100. Higher numbers mean whiter, brighter paper. This is important because different paper products need different brightness levels - for example, premium office paper typically has higher brightness than newsprint. Understanding brightness is crucial for quality control and meeting customer specifications in paper manufacturing.
