TVT (Text Verification Tool®) is a text and graphic proofreading software that saves time, prevents errors, costly misprints and recalls. It easily compares your artwork file to the original manuscript and clearly marks any text or image deviations. TVT ensures that only approved content is printed or published.

Inspect files with different layouts and file formats (e.g. Word, PDF, XML, XLS, AI) and catch deviations early in the process. All actions and review performed by users are documented in a report. This provides a fully compliant audit trail.

Get more products to market in less time, with greater accuracy. Inspect text, tables, multilingual documents (including Braille and right-to-left languages), images and full-page artwork in one tool.
