WASHING DEVICE AND WASHING METHOD

Provided are a washing device and a washing method that achieve prevention of development scum adhesion, development uniformity, and development speed at the same time. This washing device performs development using a washing solution while transporting the flexographic printing plate precursor after imagewise exposure. The washing device includes a transport unit that transports the flexographic printing plate precursor along a predetermined transport path and a development unit that performs development on the flexographic printing plate precursor. The development unit includes a brush which is used for the development and a driving unit which controls rotation of the brush around a rotation axis and movement of the brush. The brush removes an unexposed portion of the flexographic printing plate precursor to perform the development, and the rotation axis of the brush is a fixed axis passing through one point in the brush. The driving unit rotates the brush in a state in which the rotation axis of the brush passes through a surface of the flexographic printing plate precursor, and moves the rotation axis of the brush in at least one direction intersecting the rotation axis.

System and process for persistent marking of flexo plates and plates marked therewith

Systems and processes for making a flexo plate, and plates made thereby. Non-printing indicia defined by areas of presence and absence of polymer in the plate floor created using microdots imaged during a LAMS layer imaging step are readable downstream of the washing or other non-cured-polymer-removal step but not to print in the printing step. The non-printing indicia may define a repeating pattern of alphanumeric characters, non-text graphics, or a combination thereof. A difference in growth of plate structures corresponding to different types of microdots may be used for characterizing processing conditions.

Printing plate workflow controlled with the aid of the transport cart

A method correctly mounts printing plates in a printing press. The method uses prepress software, a transport device, an identification device disposed on the transport device or on a printing plate, and a scanning device. The prepress software defines a sequence of print jobs to be processed by the printing press and sends data for making the printing plates for the print jobs defined in the processing sequence to a platesetter. The platesetter produces the corresponding printing plates. The produced printing plates are deposited on the transport device, the transport device is conveyed to the printing press, and the identification device of the transport device or of a printing plate is scanned by a scanning device at the printing press and the print jobs that have been identified in this way are compared to the print jobs which the prepress software has assigned to the printing press.

Photosensitive printing form for a flexographic printing method comprising visible and non-printable information, and method for preparing such a printing form

A photosensitive flexographic printing form, and process for manufacturing the same. The printing form includes a base, a first series of relief patterns having a first elevation with respect to the base in an image area of the base, and a second series of relief patterns having one or more elevations lower than the first elevation and located outside of the image area.

Nonplanar patterned nanostructured surface and printing methods for making thereof

A method of applying a pattern to a nonplanar surface. A stamp has a major surface with pattern elements having a lateral dimension of greater than 0 and less than about 5 microns. The major surface of the stamp has a functionalizing molecule with a functional group selected to chemically bind to the nonplanar surface. The stamp is positioned to initiate rolling contact with the nonplanar surface, and contacts the nonplanar surface to form a self-assembled monolayer (SAM) of the functionalizing material thereon and impart the arrangement of pattern elements thereto. The major surface of the stamp is translated with respect to the nonplanar surface such that: a contact pressure is controlled at an interface between the stamping surfaces and the nonplanar surface, and a contact force at the interface is allowed to vary while the stamping surfaces and the nonplanar surface are in contact with each other.
