摘要： An apparatus for treating a relief precursor having a back side and a relief side. The apparatus includes a housing, a treating means for treating the relief precursor with at least one liquid, a removal means for removing debris and/or liquid from the relief precursor, the removal means arranged downstream of the treating means, and a conveying mechanism configured for transporting the relief precursor in a transport direction through the housing. The removal means includes a liquid removal and guidance body mounted for removing liquid from the back side of the relief precursor. The conveying mechanism is configured for pulling the relief precursor over and against said liquid removal and guidance body whilst the relief precursor is moved in the transport direction, such that in operation liquid is removed from the back side.

摘要： There is provided a method of cleaning a print roller and a system for performing the same. The method comprises providing an ultrasonic cleaning bar having at least one ultrasonic energy source. The ultrasonic cleaning bar is engaged with an ink-carrying surface of the print roller, the ultrasonic cleaning bar and the ink-carrying surface defining a trough therebetween for containing a cleaning fluid. A cleaning routine is executed, the cleaning routine comprising: filling the trough with the cleaning fluid so that the cleaning fluid contacts the ink-carrying surface; activating the ultrasonic energy source for a period of time to remove contaminants from the ink-carrying surface of the print roller so that the contaminants become suspended in the cleaning fluid; and draining the suspension of cleaning fluid and contaminants from the trough. The method comprises executing the cleaning routine at least two times in succession before cleaning of the print roller is complete.

摘要： A method for cleaning a printing fluid off a surface of at least one rotatable component of a printing press includes selecting and executing one of a plurality of predefined cleaning operations in an automated way. The selection is made on the basis of a predefined mathematical model executed on a computer and, when the model is executed, a parameter corresponding to an amount of the printing fluid present on the surface is calculated. The improved cleaning method may be applied in all modes of operation of the printing press and in particular allows detergent, cleaning cloth, and/or water to be saved.

摘要： A vacuum wiper, comprising a housing, a connection port, multiple holes and a hole adjusting means; the housing contains a cavity; the connection port is disposed on the housing and is in communication with the cavity; the multiple holes are disposed on the housing in the length direction of the housing, such that the cavity of the vacuum wiper housing is able to be in fluid communication with the outside via the multiple holes. The vacuum wiper has a maximum vacuumizing length when all of the multiple holes are in communication with the outside. The hole adjusting means is configured to be capable of blocking one or more of the multiple holes in sequence from two ends in the length direction of arrangement of the multiple holes of the vacuum wiper, such that the vacuum wiper is able to adjust the vacuumizing length. The provision of the hole adjusting means enables the vacuum wiping apparatus to have an adjustable vacuumizing length, in order to match the wiping of stencils with different length specifications, thereby effectively increasing the vacuumizing efficiency of the vacuum wiping apparatus and reducing the production cost.

摘要： A printing device for printing substrates, such as circuit boards, wafers, or solar cells, has at least one movably mounted printing unit with a working surface on which the substrate to be printed can be placed. The printing unit is paired with a transport belt device, which has a supply roller with a transport belt wound thereon, a collection roller for winding up the transport belt, and two deflecting surfaces, in particular deflecting rollers, which are paired with the working surface. The transport belt is guided by the supply roller over one deflecting surface and onto the working surface in order to form a contact surface for the substrates, and by the working surface over the other deflecting surface to the collection roller. The deflecting surfaces can be moved together with the respective printing unit. The supply and collection rollers are held on the printing device in a stationary manner.
