Abstract
Test printing apparatus for test printing, wherein printing ink is printed on a test substrate. An ultraviolet irradiation assembly is mounted adjacent the rotary path of the bearing surface bearing the test substrate, for emitting ultraviolet radiation against the test substrate. The apparatus has a control arranged for controlling the drive for imparting to the bearing surface a speed in the sense of rotation, which during the irradiation of the test substrate by the irradiation assembly is different from the speed that is imparted by the drive to the bearing surface during the printing of the test substrate. An irradiation assembly and a method for test printing are also described.
Claims6
A test printing apparatus for test printing, in which printing ink is printed on a test substrate, which apparatus comprises:
- a bearing surface for bearing the test substrate, circulatable along a rotary path,
- a drive for circulating the bearing surface;
- a detector for detecting at least defined rotary positions in a sense of rotation of the bearing surface;
- at least one printing surface adjacent the path of the bearing surface for causing the printing surface to roll over a test substrate on the bearing surface for printing the test substrate;
- a control communicating with the detector and with the drive for controlling the drive, depending on the position of the bearing surface, for causing the bearing surface to move in different sections of the rotary path with predetermined, different speeds in the sense of rotation;
- and
- an ultraviolet irradiation assembly mounted adjacent the path of the bearing surface for emitting ultraviolet radiation against the test substrate attached to the bearing surface,
- wherein the control is arranged for controlling the drive for imparting to the bearing surface a speed in the sense of rotation which during irradiation of the test substrate by the irradiation assembly is different from the speed that the drive imparts to the bearing surface during the printing of the test substrate.
A method for test printing, in which printing ink is printed on a test substrate, comprising:
- circulating along a rotary path a test substrate borne by a bearing surface circulatable along the path;
- detecting at least defined positions in a sense of rotation of the bearing surface;
- rolling a printing surface over a test substrate on the bearing surface in a position along the rotary path along which the test substrate passes for printing the test substrate;
- controlling the drive, depending on the position of the bearing surface, for causing the bearing surface to move in different sections of the rotary path with predetermined, different speeds in the sense of rotation;
- and
- after printing, emitting ultraviolet radiation against the test substrate in an irradiation section of the rotary path;
- wherein the bearing surface, during the emission of ultraviolet radiation against the test substrate, is moved with a different speed in the sense of rotation than during the printing of the test substrate.
