Why is preflighting important?
The preflighting process is important in print production because one must check for errors made to a document before sending it for final print or otherwise, such errors will remain intact. These errors include font issues, improper bleeds, spot colors and image resolution issues; while some can be detected upon passing, others are hard to spot, especially for minute details. More so, the size of the affected area of error may make it near inconspicuous upon normal viewing. To reiterate, if these issues are not spotted (hence if preflighting is not enacted) the final print will carry these mistakes, which can be very costly to fix.
