Claims3
A method of manufacturing coated paper that is on-line with a papermaking machine and that performs a papermaking process, a coating process, and a flattening process, wherein
- said papermaking process is performed by a twin wire former in which a paper material is injected from a head box to between two wires each of which loops to form a paper layer, thus making a paper web;
- said coating process uses a coating facility that comprises a roll coater coating facility for coating both skies of a paper web, a first blade coater coating facility for coating one side of a paper web, and a second blade coater coating facility for coating another side of the paper web, said roll coater coating facility being provided between the first and second blade coater coating facilities, and
- said coating process performs said coating process on said paper web using only the roll coater coating facility when an amount of coating material to be coated on one surface of the paper web is 7 g/m2 or less, and using only the first and second blade coater coating facilities when the amount of coating material to be coated on one surface of the paper web is greater than 7 g/m2, and
- then said flattening process is performed on said paper web by a flattening facility.
