Bear imprint content felt, loiter is dirty
Breakdown reason: 1. Water Chinese ink does not work; 2. Answer roll pulling force is too large; 3. The room temperature that deposits presswork is too high
Remove measure: 1. Raise dry temperature; 3. Reduce answer roll tension; 4. Presswork finished product is put in cool place
Burnt edition, block up edition
Breakdown reason: 1. Forme is too shallow; 2. Presswork pressure is too great; 3. The quantity that offer Chinese ink is too much; 4. Viscosity of water Chinese ink is too tall; 5. Rate of dry of water Mo Gan is too rapid;
Remove measure: 1. Deepen forme; 2. Adjust presswork pressure; 3. Reduce the amount that offer Chinese ink; 4. Reduce the viscosity of water Chinese ink; 5. Drop dry temperature
Fold color undesirable
Breakdown reason: 1. Imprint in polychromatic overprint when the color from the back, before monochromatic did not work; 2. Before the color that imprints after makes monochromatic happening come off phenomenon; 3. The lubricious superimposition that imprints after does not go up
Remove measure: 1. Raise monochromatic and dry rate; 2. After reducing, imprint the viscosity of lubricious Chinese ink or reduce presswork pressure; 3. The monochromatic viscosity after reducing or raise its to add exert oneself
Presswork pinhole
Breakdown reason: 1. Water Chinese ink works too quickly on Mo Gun, send handwriting or painting not divide evenly;
Remove measure: 1. Decelerate the dry speed of water Chinese ink;
Color is too light
Breakdown reason: 1. The viscosity of water Chinese ink is too low; 2. Reticulation roller reticle is too fine; 3 reticulation roller wears away or did not clean clean; 4. Chinese ink is measured on too small
Remove measure: 1. Raise the viscosity of water Chinese ink; 2. The reticulation roller of exchange thick reticle; 3. Change with new reticulation roller or undertake be cleaninged thoroughly to reticulation roller; 4. Reduce the roller that send handwriting or painting or blow Mo Dao's pressure or increase edition platen pressure appropriately (form of intaglio printing) , accelerate presswork speed (soft edition)
Color is too deep
Breakdown reason: 1. The viscosity of water Chinese ink is too tall; 2. Reticulation roller is too thick; 3. Water Chinese ink colour saturation is too tall; 4. Chinese ink is measured on too big
Remove measure: 1. Add thinner to reduce viscosity; 2. Change fine reticulation roller; 3. Add remove weak agent to reduce color deepness 4. Raise the roller that send handwriting or painting or blow Mo Dao's pressure or reduce edition platen pressure appropriately (form of intaglio printing)
