摘要:
A method for controlling a quantity of medium transferable from a screen roller of a printing machine onto a roller that is in contact with the screen roller includes exerting an influence upon a difference in circumferential speed between the screen roller and the roller in contact therewith, and further includes controlling the difference in the circumferential speed as a function of the printing speed of the printing machine, so that printed medium density remains at least approximately constant at least within a wide printing speed range.

A print controller which produces a device specific raster for its printer and also produces a rasterized output in portable and more editable form for export and re-use as an input by other printers which may have different parameters. If the input is in a device independent color space, the rasterized export also will be in a version in a device independent color space, typically CIELAB. If the input is in a printable device dependent color space such as CYMK, the output will be an more editable rasterized version in the same color space, with any printing hints that were in the original will be included in the output. In any case, an override can be provided to change the default selection to any other user-identified version. An example of a device independent color space is CIELAB, of a device dependent version applicable for a number of printers with similar parameters is SWOP CMYK, and of a device dependent version is a printer specific CMYK.

In a print service method for a printing system, text data contained in a mail received by a mobile phone owned by a user, and attachment file data attached to the received mail are downloaded into the printing system from the mobile phone. Application software corresponding to the attachment file data is selected from application software stored in the printing system, thereby opening the attachment file data by using the selected application software. The text data and the attachment file data opened by the selected application software are printed onto a printing medium.

A sheet processing device is provided in a sheet-fed printing press. Sheets are conveyed to a sheet transport cylinder and are processed on the sheet transport cylinder. The sheets are each removed twice from the sheet transport cylinder.

A kiosk printer for unattended operation is equipped with a presenter to prevent a user from prematurely trying to remove a printed document. The presenter has motor driven feed rollers and a document sensor for determining when the printing document is in the presenter document path. The presenter has a home position adjacent to the printer document exit path. When printing starts, the document enters the presenter feed rollers and is sensed by a document sensor. A drive motor moves the presenter at the same rate as the printing document. When the presenter reaches a feed position it stops and the document sags and forms a document loop as printing continues. When printing stops, the presenter feed rollers feed the document from the kiosk to a user. When the printed document has exited the presenter, the presenter returns to the home position awaiting succeeding printed document.

A clock generator for generating a clock signal for an imaging device serving for transferring image-setting information to a rotatable printing form which includes an input to which an actual value signal dependent upon an angular position of the printing form is applicable, and an output for outputting the clock signal. It further includes a first comparator having a first input whereto the actual value signal is applicable as an analog signal, a second input to which an analog nominal value signal, respectively, representing a nominal value for the angular position of the printing form, is applicable, and an output for outputting the clock signal formed as a function of a result of a comparison between the analog actual value signal and the analog nominal value signal; an imaging device and a printing machine including the clock generator; and a method of generating a clock signal for an imaging operation.
摘要:
Press profile production, color management and printed sheet systems and methods provide for a highly accurate press profile that is unaffected by in-plane irregularity in density due to the ink keys unique to a given press in a printing process in which color management is performed. Thus, more accurate color matching can be achieved between a first press and another press or other device, among other advantages. A press profile production system according to an embodiment of the invention provides a print layout with a profiling target disposed within the width of one ink key of the press.

A method of feeding dampening water includes a density measuring step for measuring densities of first and second detecting patches 101 and 102 printed adjacent each other on printed matter 100 and presenting a difference in density variations after printing with varied feed rates of damping water and ink, a dampening water feeding step for controlling the feed rate of dampening water based on the densities of the first and second detecting patches 101 and 102 measured in the density measuring step, and an ink feeding step for controlling the feed rate of ink based on the densities of the first and second detecting patches measured in the density measuring step, and the feed rate of dampening water.
摘要:
A printer 100 sends status information, ID information and the like to a network device 200 before entering an energy conservation mode in which it is unable to communicate with external devices, so that the network device 200 will respond to a status information request on its behalf. Where a PC 300 requests status information from the printer 100, the network device 200 in which substitute response setting was put in effect responds with the printer 100 status information on behalf of the printer 100. By receiving the status response from the network device 200, the PC 300 can verify that the printer 100 is connected to the network 400. The PC 300 can also send a release order that releases the printer 100 from the energy conservation state so that it can initiate printing.
