Abstract
A method for reducing artifacts in a color printed image, that are perceivable by the naked eye, includes using a different imaging beam to start imaging each printing plate that is used for a different color plane. Alternatively, a different set of imaging beams may be used to image each printing plate used for a different color plane. The method does not require manipulating image data. The method diffuses some errors throughout the printed image and prevents some errors from being imaged and/or printed which reduces or eliminates the visible perception of artifacts.
Claims44
A method of preventing perceivable artifacts from being formed in a composite image comprising the steps of:
- imaging a plurality of printing plates using an imaging apparatus having a plurality of imaging beams, said plurality of printing plates used for a same print job;
- and
- using a different imaging beam of said imaging apparatus as a starting beam to image each of said plurality of printing plates.
A method of reducing perceivable artifacts in a composite image comprising the steps of:
- imaging a plurality of printing plates using an imaging apparatus having a plurality of imaging beams, said plurality of printing plates used for a same print job;
- and
- using a different imaging beam of said imaging apparatus as a starting beam to image each of said plurality of printing plates.
A method of preventing perceivable artifacts from being formed in a printed image comprising the steps of:
- imaging a plurality of printing plates using an imaging apparatus having a plurality of imaging beams, said plurality of printing plates used for a same print job;
- using a unique set of said plurality of imaging beams to image each of said plurality of printing plates;
- and
- wherein each of said printing plates is operative to transfer a unique color of ink from an ink supply to a same substrate, when said plurality of printing plates are used on a multi-color printing press.
A method of preventing perceivable artifacts from being formed in an image that is produced using a multi-color printing press comprising the steps of:
- imaging a plurality of printing plates using an imaging apparatus having a plurality of imaging beams, said plurality of printing plates used for a same print job;
- using a different imaging beam of said imaging apparatus as a starting beam to image each of said plurality of printing plates;
- and
- wherein each of said printing plates is operative to transfer a unique color of ink from an ink supply to a same substrate when each of said printing plates is used on said multi-color printing press.
A method of reducing perceivable artifacts in an image that is produced using a multi-color printing press comprising the steps of:
- imaging a plurality of printing plates using an imaging apparatus having a plurality of imaging beams, said plurality of printing plates used for a same print job;
- using a different set of imaging beams of said imaging apparatus to image each of said plurality of printing plates;
- and
- wherein each of said printing plates is operative to transfer a unique color of ink from a ink supply to a same substrate when each of said printing plates is used on said multi-color printing press.
A method of imaging a plurality of printing plates comprising the steps of:
- providing a plurality of printing plates, wherein each printing plate is designated for use with a unique color plane for a same print job;
- imaging each of said plurality of printing plates with an imaging system having a plurality of imaging beams;
- and
- wherein a unique set of said plurality of imaging beams is used to image each of said plurality of printing plates.
A method of printing images on a substrate comprising the steps of:
- providing a plurality of imaged printing plates for use on a printing press for a same print job;
- transferring an image from each of said plurality of printing plates to a same printable substrate;
- wherein each of said plurality of printing plates is used with a different color plane on said printing press;
- and
- wherein each of said plurality of printing plates is previously imaged using a multi-beam imaging machine, and wherein each of said plurality of printing plates is imaged using a different starting beam on said multi-beam imaging machine.
A method of obscuring or hiding artifacts in a printed image comprising the steps of:
- imaging a plurality of printing plates using an imaging apparatus having a plurality of imaging beams, said plurality of printing plates used for a same print job;
- and
- using a different imaging beam of said imaging apparatus as a starting beam to image each of said plurality of printing plates.
