Abstract:
1. A liquid transfer method for use with a liquid transfer apparatus which applies overall coating which transfers liquid on an entire surface of one side or both sides of a sheet and partial coating which transfers liquid on a specific portion of one side or both sides of the sheet, the method comprising the steps of: positioning a first notch of a liquid supply cylinder and a starting end of an first effective impression area which is continuous to the first notch respectively upstream of a second notch of a transfer cylinder that is in contact with said liquid supply cylinder and a starting end of a second effective impression area which is continuous to the second notch in a rotational direction of said liquid supply cylinder by rotating said liquid supply cylinder; conveying the sheet by holding the sheet by a transport cylinder; supplying said liquid from said liquid supply cylinder to said transfer cylinder while maintaining a phase relationship between said liquid supply cylinder and said transfer cylinder in the positioning step; and transferring the liquid to the entire surface of one side of the sheet by the transfer cylinder and transferring the liquid to the entire surface of the other side of the sheet by the transport cylinder, wherein the step of transferring comprises a step of positioning an edge, on a downstream side in a sheet convey direction, of the entire surface of one side of the sheet where the liquid is to be transferred, upstream of an edge, on a downstream side in the sheet convey direction, of the entire surface of the other side of the sheet where the liquid is to be transferred.
