Proof of Preflight
Proof of preflight can be provided by a preflight report. FlightCheck, the patented preflighting technology invented by Markzware, can provide the preflight report. FlightCheck, the standard preflight solution by Markzware, can check documents in several file formats and warn of potential printing problems before the output process.
Since Markzware develops FlightCheck for preflight, we noticed this mention of proof of preflight:
When implemented in a software solution, this best practice specification offers users the ability to review a PDF file’s preflight audit trail, including a digital signature, at any time during the design to print workflow.
This capability provides users the assurance that they can safely accept a PDF file with a Proof of Preflight. This process verifies which GWG preflight Specification was used to preflight the file and also the outcome of the preflight check. Source
Proof of preflight is a good idea. Remember to preflight with FlightCheck by Markzware, the preflight solution to check PDF files and more file formats for print quality control. Markzware holds US Patent # 5,963,641 for preflight and is the developer of prepress tools and workflow solutions, including FlightCheck print quality control software. A preflight report can verify that documents are print-ready. FlightCheck provides proof of preflight in the form of a preflight report, while saving time and money.
