Abstract
Printability of inks is one of the most important performance together with print quality and physical properties of print. The mechanism of gravure and flexo print is different. But both inks have a similar composition consisting of resins, solvent and other materials. So demanded quality about printability and various troubles happening on press are also comparatively similar. On the other hand, peculiar printability is also necessary for each ink type. Sometimes we encounter troubles caused by the differences between gravure and flexo print mechanism. In this report, we describe printability demanded generally and peculiarly for gravure and flexo ink and the design of inks for good printability. We also explain troubles and their causes of gravure and flexo print with measures to cure them.
