Abstract: There is prepared a printing plate on which a material being hydrophilic at a first temperature and being hydrophobic at a second temperature which is lower than the first temperature is provided. First, the whole surface of the printing plate is forcibly made either one of hydrophobic or hydrophilic. Next, a region having the other nature out of hydrophobic and hydrophilic is formed so as to correspond to an image to be printed. Then, ink is supplied onto the region having hydrophobic nature to conduct offset printing.

Abstract: A process for imaging a lithographic printing plate having a presensitizing coating. An ink jet printer is used to apply imagewise micro drops of an insolubilizing solution that insolubilizes exposed areas of the coating. The latent image is then developed. The process works with conventional, commercially available developing processors.

Abstract: The present invention provides a plurality of destination screens having a plurality of pages, in which a plurality of destination selection keys are displayed. The destination screens are displayed in layers, each screen having a tag to select a desired destination screen. When a specific tag is selected, a page of the corresponding destination screen with a registered destination selection key is displayed. When page scroll key are pressed, the registered destinations can be searched as each page of the destination screens is scrolled in the ascending/descending order. When no more pages can be scrolled in one destination screen, another destination screen is displayed, instead of terminating the operation. Therefore, it is not necessary to perform a separate operation to switch to another screen, when no more pages can be scrolled by pressing a page scroll key. Accordingly, it is possible to reduce the operator's burden to find a desired destination, thereby improving the convenience of the operation.

Abstract: A method and sensor for determining the ratio of two components in a fluid mixture comprising a test cell in open communication with the fluid mixture and a reference cell containing a desired fluid mixture not in contact with the fluid mixture being tested, said reference and test cells having the same cell geometry. By use of a capacitance divider system, one determines the relative capacitances of said cells correlated with the dielectric constants of the respective fluid mixtures and ascertains the ratio of one component to the other component in the fluid mixture on the basis of the linear and monotonic correlation between the dielectric constant of the mixture at a given temperature and the ratio of one component to the other component. Preferably a mixture of methanol and water is tested such as for use as a feed to a reformer used in supplying hydrogen to a fuel cell. A fixed capacitor equivalent to the reference cell at a given temperature is usually substituted for the latter.

Abstract: A method of printing employing a printing plate prepared from a printing plate precursor comprising a layer A capable of being removed by water or both water and ink on a printing press comprises the steps of imagewise exposing the precursor, mounting the precursor on a plate cylinder of the printing press to fix the precursor at a fixing section on the plate cylinder, providing a water repellent area in the layer A of the precursor so that the water repellent area is provided between a portion of the layer A to be used for printing and a portion of the layer A in the fixing section not to be used for printing, supplying water or both water and ink to the resulting precursor to obtain a printing plate; and then carrying out printing while supplying water or both water and ink to the resulting printing plate.

Abstract: In a method and apparatus for perforating a heat sensitive stencil sheet having a heat shrinkable film, the film is selectively heated with a heating device to form independent dot perforations corresponding to an image, and the heating device is controlled to ensure that the perforations satisfy the following formula (1): p≧d+({square root over ( )}2)f  (1) where p denotes a scanning pitch in a main scanning direction or a sub scanning direction; d denotes an inner diameter of a perforation in the same direction as p; and f denotes a width of a rim of said perforation at a portion that is not merged with any rims of its adjacent perforations. Irregularity of perforation configuration is decreased, size of perforations is kept adequate, and the heating device does not have to be heated to a high temperature.

Abstract: A method for improving security with a printer and sensitive hardcopy output. The method comprises examining incoming print jobs for indication of sensitivity and need for increased security. Any such identified job when printed is monitored. This monitoring is accomplished by watching a sensor provided on the output bin. When the identified job is removed from the printer a message is sent to the originator of the print job with a time stamp indicating that the hardcopy output has been removed.

Abstract: In a rotary press, a first press roller adapted to retreat during printing and advance during plate changing to contact a web is provided on a travel route of the web between a printing unit and a dryer. A second press roller having the same function as the first press roller is provided on the travel route of the web between air infeed unit and the printing unit. A web presser for pinching the web is provided on the travel route of the web between the infeed unit and the second press roller. With the web being pinched by the web presser, the first press roller and the second press roller can be moved by the web in a retreating direction. After plate changing is completed, the press rollers can smoothly ascend regardless of their pressure, and can promptly and smoothly return to the state before plate changing.
