A hand-operated cooling device for cryotherapy for treating pain, includes a main body and a receptacle, which can be inserted at least partially into the main body, for the exchangeable accommodation and insertion of a gas pressure vessel. The main body includes a manual gas outlet actuation arrangement, which can effects the outflow of a gas from the gas pressure vessel when the receptacle is inserted. The receptacle includes a cooling surface, which can be cooled by the outflowing gas and by the gas pressure vessel jacket, wherein the gas can be conducted inside the main body and inside the receptacle by a gas conducting arrangement and can exit at the receptacle adjacent to the cooling surface. Commercially available gas pressure vessels, can be inserted into the cooling device, so that a simple and cost-effective use of therapeutic OT medical cryotherapy having a pleasant cooling effect is made possible.

A method for detecting errors in individual color separation images of a multi-color printing machine, in particular an electrophotographic printing machine, comprising a plurality of printing units, is described. Using this method, first a plurality of first register lines is printed with a first printing unit, and a plurality of second register lines is printed with a second printing unit in such a manner that each of the first register lines, together with one of said second register lines, is positioned inside a respective registration frame. Then the plurality of the first and second register lines in the respective registration frame are detected with a register sensor, and an output signal of the register sensor relating to the respective second register line is compared with an intensity threshold value in order to determine whether the second register lines can be recognized. In an alternative embodiment of the method, a plurality of the first register lines is printed with a first printing unit in such a manner that each of the first register lines is printed within a respective registration frame. Subsequently, the plurality of the first register lines in the respective registration frames is detected with a register sensor, and an output signal of the register sensor relating to the respective first register lines is compared with a pre-specified intensity threshold value in order to determine whether the first register lines are recognizable.

A method for calibrating a position of a first register line in a register mark for a multi-color printing machine, said first register line consisting of a first color that does not offer sufficient contrast with respect to a printing material to allow detection above a determined threshold on a register sensor. A plurality of register marks, each consisting of at least one starting line, a background line and a first register line, is printed, said background line consisting of a second color which offers sufficient contrast with respect to the first color for detection above the specified threshold on the register sensor if the first register line is printed on the background line, and said background line having a width that is greater than the first register line, and said starting line, said background line and said first register line being printed with the use of the pre-determined control parameters, which normally cause the first register line to be printed on the background line. Subsequently, it is detected whether the first register line has been recognized by the register sensor above the predetermined threshold as being completely positioned on the background line. If not, then at least one predetermined control parameter for printing the first register line is changed and printing of the register marks and the detection are repeated. Changing of the at least one control parameter may be repeated one or more times, with the first register line being shifted each time with respect to its width.

The invention relates to a method and a device for controlling the circumferential register in a digital multi-color printing machine for printing sheets during a printing process, whereby, for each sheet, at least one register mark per color printing unit of the multi-color printing machine is produced, assigned to said sheet and defined with respect to its position, and whereby, based on the determination of the position of the register marks of a sheet, the circumferential register of at least one sheet, which follows the sheet associated with said determined register marks downstream of the printing process, is controlled. In duplex printing a sheet by recto and verso printing with the invention, register marks are applied for each side and, in order to control recto and verso printing of at least one subsequent sheet, said register marks are analyzed.

A device and a method using a printing device and system for printing sheets whereby, for each sheet, at least one register mark per color printing unit of the multi-color printing machine is produced, assigned to said sheet and defined with respect to its position, so that in duplex printing register marks are applied to each side. The position of each mark is determined by analyzing the position of the mark assigned to the appropriate previous recto or verso sheet.

The invention relates to a method and apparatus for minimizing the influence of register differences in multicolor printing, in particular in digital printing processes, register values () in the transport direction (), which are different transversely with respect to this direction being set to a value between the extremes ('). The invention is intended to carry out a development such that the influence of register differences on the image quality can be minimized reliably and to a great extent. This is achieved by a number of individual values of the register values () being measured and an average value (&#x2032;) being determined from these and brought into alignment with the average value (&#x2032;) from at least one further color printing unit (&#x2032;&#x2033;).

Method and apparatus for setting registration in a multicolor printing machine based on printing substrates

A method and apparatus for setting registration in a multicolor printing machine for the digital production of color separations, the actions of setting up and combining color separations being controlled when printing substrates of a different grade are fed in, in order to correct registration setting. In the event of a change in the printing substrate grade, the influence of this change on registration can be compensated for optimally before the printing substrate ( ) is fed to the printing process. When the printing substrate grade is changed, the influence of all the properties of the printing substrate ( ) that are relevant to registration is taken into account directly as the change is implemented, by correction values ( &prime;, . . . ) for the printing substrate ( ) that are available before printing is carried out.
