Abstract
A method is provided which reduces substrate waste while adjusting the press parameters to obtain a satisfactory image. The method includes the steps of: supplying a web to a printing press; printing a plurality of first images on the web at corresponding printing positions; inspecting one of the first images on the web; rewinding the web to one of the printing positions; and printing a further image over one of the first images on the web. A printing press is also provided which is configured and arranged to print in accordance with the method.
Claims13
A printing press comprising:
- a web supply supplying a web to the press;
- at least one printing unit configured and arranged to print images on the web at corresponding printing positions;
- an inspection unit configured and arranged to inspect the images on the web;
- a rewind device configured and arranged to rewind the web to one of the printing positions;
- a controller,
- the controller coupled to the at least one printing unit and the rewind device, the controller configured and arranged to
- control the at least one printing unit to print first images on the web at corresponding printing positions, and,
- after the inspection unit inspects the first images on the web and a determination is made using the inspection unit that the first images are not acceptable, control the rewind device to rewind the web to one of the printing positions, and
- thereafter, prior to printing at least one further image, control the at least one printing unit to make adjustments to the printed image or the at least one printing unit, and
- thereafter, control the at least one printing unit to print at least one further image over at least one of the first images on the web.
A method for printing an image comprising the steps of:
- supplying a web to a printing press;
- printing a plurality of first images on the web with at least one printing unit at corresponding printing positions;
- inspecting one of the first images on the web with an inspection unit;
- rewinding the web with a rewind device to one of the printing positions;
- and
- providing a controller,
- the controller coupled to the at least one printing unit and the rewind device, the controller configured and arranged to
- control the at least one printing unit to print first images on the web at corresponding printing positions, and,
- after the inspection unit inspects the first images on the web and a determination is made using the inspection unit that the first images are not acceptable, control the rewind device to rewind the web to one of the printing positions, and
- thereafter, prior to printing at least one further image, control the at least one printing unit to make adjustments to the printed image or the at least one printing unit, and
- thereafter, control the at least one printing unit to print at least one further image over at least one of the first images on the web.
