Harvesting takes place between November and February. One year shrubs are preferably chosen for their soft fibers. The branches are cut to a length of 1.20m; to facilitate the peeling of the bark, the bundles are spread in a metal pot filled with water and are covered with a thick coarse cloth which will retain the steam. The device is heated for 5-7 hours.

After steaming the bark can be directly separated from the wood and then dried in the sun. The bark is called at this stage "black bark" because of its outer layer which should be removed. It is scraped with a knife.

The white bark is left to soak for one day to facilitate the removal of soluble elements and penetration into the fibers of the alkaline solution. Then the bark is cut and assembled into bunches for an alkaline cooking. The barks are placed in a vat containing a caustic lye and boiled for three to four hours. This operation removes lignin and non desirable materials (pectins, starches). Alkaline agents are either plant ashes or alkaline chemicals (soda, lime or sodium carbonate). After cooking, the barks are rinsed in running water for half a day to remove detergent and dissolved substances. The barks are immersed longer in running water, for several days in order to expose them to sunlight and to bleach them.

The removal of hard impurities is done by hand in cold water.
The pulp is then beaten by various methods: using sticks on a flat stone or a wooden disk, a vertical beater and more recently in the Japanese hollander called naginata.
To proceed to sheet making, the tank is first filled with water and the pulp is poured into the vat. The dispersing agent is added and the pulp is whipped. The methods used are called webal, ssangbal and jangpanji. In the webal method, the sheet is usually formed of two layers. The sheet is couched on a wooden board; either one sheet is couched alone, or a second sheet is laid on its surface, head to tail to form a single sheet. The Ssangbal method is derived from Japanese nagashizuki returned after 1900 (the method had been imported in the early 15th century when production should be accelerated). In Jangpanji, which is used for the manufacture of large format sheets, the mould is maintained by two people at each large end. The sheet is formed by successive layers of pulp.
In all cases, the sheets are couched with the movable screen in a stack and are separated or not by an intermediate element (thread, grass stem) to facilitate separation after pressing. Before lifting the screen, the pile of sheets is pressed with a wooden roller to eliminate air bubbles. The pressing is carried out under load or in a lever press. The draining is slow (12 hours). To be dried, the sheets are brushed on a smooth surface: wooden desks, on the floor made with oiled papers, on a heated metal plate.

Calendering or Dochim is the step that makes paper more compact, less porous and gives it a smooth surface. The sheets are moistened into small packs of ten and are then hammered on a flat stone with a foot hammer (currently a motorized hammer).

La récolte a lieu entre novembre et février. Les arbustes d’un an sont choisis de préférence pour leurs fibres tendres. Les branches sont coupées à une longueur d’environ 1m20 ; pour faciliter le pelage des écorces, les fagots sont couchés dans un chaudron métallique rempli d’eau où ils sont recouverts d’une toile grossière épaisse qui permet de retenir la vapeur. Le dispositif est chauffé pendant 5 à 7 heures.

Après étuvage les écorces peuvent être directement séparées du bois puis mises à sécher au soleil.

L’écorce est appelée à ce stade « écorce noire » à cause de sa couche la plus externe qui doit être éliminée. Elle est grattée à l’aide d’une lame de couteau.

L’écorce blanche est laissée à tremper pendant toute une journée pour faciliter l’élimination des éléments solubles et la pénétration dans les fibres de la solution alcaline. Puis les écorces sont coupées et réunies en paquets pour la cuisson alcaline. Les écorces sont placées dans un baquet contenant une lessive caustique pour bouillir pendant trois à quatre heures. Cette opération permet d’éliminer la lignine et les matières incrustantes (pectines, amidons). Les lessives sont préparées soit à base de cendres de bois soit de réactifs alcalins (soude, chaux ou carbonate de sodium). Après cuisson, les écorces sont rincées dans l’eau courante pendant une demi-journée afin d’éliminer lessive et substances dissoutes.

Pour blanchir les écorces, leur immersion dans l’eau courante se prolonge pendant plusieurs jours afin de les exposer au soleil.

L’élimination des impuretés dures ou colorées est effectuée à la main dans l’eau froide

La pâte est ensuite écrasée selon diverses méthodes : à l’aide d’un long gourdin sur une pierre plate ou sur une planche de bois dur, d’un battoir vertical et plus récemment en pile hollandaise japonaise appelée naginata.

Pour procéder à la mise en feuille, la cuve est tout d’abord remplie d’eau puis la pâte est versée dans le cuvier. Un agent dispersant est rajouté à la pâte qui est brassée.

Les méthodes utilisées s’appellent webal, ssangbal et jangpanji.

Dans la méthode du Webal, la feuille est formée en général de deux couches. Elle est couchée sur une planche en bois : soit la feuille est déposée seule, soit une seconde feuille est déposée à sa surface, tête-bêche pour ne former qu’une seule feuille.

La méthode du Ssangbal est dérivée du nagashizuki japonais qui réapparait  après 1900 (la méthode avait été importée au début du 15^e siècle quand la production devait être accélérée).

Dans le Jangpanji, qui est utilisé pour la fabrication des feuilles de grand format, la forme est maintenue par deux personnes à chaque grande extrémité. La feuille est formée par couches successives de pâte. 

Dans tous les cas, les feuilles sont couchées à l’aide du tamis mobile en une pile ; elles sont séparées ou non par un élément intercalaire (fils, tiges) qui facilitera la séparation après le pressage. Avant de soulever le tamis, le tas de feuilles est pressé à l’aide d’un rouleau de bois afin d’éliminer les bulles d’air. Le pressage est réalisé sous charge ou dans une presse à levier. L’égouttage se fait lentement (12 heures). Pour être séchées, les feuilles sont brossées sur une surface lisse : planche de bois, sur le sol en papier huilé, chauffé, sur des plaques métalliques chauffées à la vapeur.

Le calandrage ou Dochim est l’étape qui rend le papier plus compact, moins poreux et qui lui donne une surface lisse. Les feuilles sont ré humidifiées en petits paquets d’une dizaine puis sont martelées sur une pierre plate à l’aide d’un maillet à pied.
