It dries or hardens to become a solid, which sticks to the doctor blade. If a doctor blade is used while it is sticking, the ink sticking to the doctor blade may dissolve again in the new ink, or the solid ink may fall off and become concave. Since it mixes with the new ink supplied to the plate roll, printing is performed with the deteriorated ink.

• Such a conventional thin film forming apparatus has the following problems.
• the elastic plate Since the elastic plate is wound around the printing roll plate cylinder while being pulled by hand, while the elastic plate is wound around the printing roll plate cylinder, the elastic plate is of a predetermined size over the entire width of the elastic plate. It is very difficult to achieve tension in the direction. If the work is not performed with as much injection window as possible, the elastic plate will be wound around the printing roll cylinder without correcting the excessive tension and slack on the entire elastic plate to be wound. As a result, the elastic plate may be attached to the printing roll plate cylinder while excessive tension is being applied, or the elastic plate may be attached to the printing roll plate cylinder while the elastic plate is wrinkled or wavy.
• ink stuck to the intaglio roll mixes with the new ink supplied to the intaglio roll. It will be inconvenient.
• the transfer amount of the ink to the printing roll is reduced accordingly, and a thin film having a sufficient thickness cannot be formed on the printing medium.
• the solvent used for wiping will be mixed as impurities into the new ink supplied to the intaglio roll. Therefore, using such an ink, for example, a liquid crystal alignment film When a polymer thin film pattern is formed, the insulating properties are reduced, and the film thickness and orientation are uneven, causing a problem that the function of the thin film is reduced.
• Wiping is performed while holding the wiper in the hands of the doctor blade while pinching the doctor blade.
• the doctor blade is pinched by the wiper at a predetermined pinching pressure, and the wiper is moved while the wiper is moved in the longitudinal direction of the doctor blade. It is extremely difficult to maintain the pinch pressure, and the pinch pressure will increase or decrease. As a result, sufficient and insufficient wiping is created, and the residual ink stuck to the doctor blade cannot be sufficiently removed. Also, the doctor blade cannot be wiped uniformly.
• the ink is filled and weighed with a doctor blade that has not been sufficiently wiped, the ink sticking to the doctor blade will be mixed with the new ink supplied to the intaglio roll.
