There is a new article online over at it-enquirer.com, which goes into some interesting details about why, how and which preflight tool should or could be used and where within your workflow. In part it says,

“Markzware has been developing FlightCheck for years, in several formats –including a highly efficient and successful online service– to accommodate for printed output, checking for trapping errors and compliance with standards such as PDF/X, for example. FlightCheck can be deployed early in the publishing process, which theoretically saves money as errors are discovered earlier and can be corrected before they cause trouble at the printing press.”

Below is a press release from IT Enquirer on a recent, detailed ROI (Return On Investment) report they did on Markzware’s Q2ID or QuarkXPress to Adobe InDesign conversion plugin. As you can see in this chart, a single license of Q2ID can have a first year ROI of over 1,000 %*! That is amazing. See exhibit from IT Enquirer report here:

* Make note: This report is using ONLY five files over a year period as an example and even with only so few, the ROI is over 1,000 percent- likely many publishers and advertising agencies will have many more than that, making the return on investment really incredible.
