Rolls of paper at a paper mill. The paper has been manufactured in a series of stages that turn wood into paper pulp and then paper. The paper here has just gone through one of the final stages, using a high temperature to apply a coating that improves the quality of the paper for printing uses. The rolls of paper are now moving on a conveyor belt (yellow) to the packaging department. Photographed at the Ortviken paper mill, Sundsvall, Sweden.
