Abstract: A thin-film forming apparatus which includes a printing device having an intaglio roll having a plurality of ink cells, an ink supply which includes a doctor blade and which fills ink into the ink cells, a printing roll with an elastic plate, to which the ink of the intaglio roll is transferred wound round the barrel surface thereof, and a printing table which fixes a to-be-printed material to which the ink of the printing roll is transferred, wherein the apparatus includes a articulated robot, and an implementation device for the printing preparatory works which is mounted to the arm of the articulated robot and which performs at least one operation among the mounting/dismounting operation of the elastic plate to/from the printing roll, the operation to wipe and/or dry the ink on the barrel surface of the intaglio roll, and the operation to wipe and/or dry the ink on the doctor blade.

Abstract: A thin-film forming elastic plate of a printing roll includes a first elastic plate holder having a first printing roll-chucking hole formed therein, and a second elastic plate holder in which a second printing roll-chucking hole having a tapered portion is formed. A printing roll barrel includes a first chuck including a first chucking member having a claw and a first driving portion for moving the claw of the first chucking member into engagement with an edge of the first elastic plate holder defining the opening of the first printing roll-chucking hole; and second chuck including a tapered portion corresponding to the tapered portion of the second printing roll-chucking hole of the second elastic plate holder, and a second driving portion for moving the second chucking member.
