I recently came across an interesting video that was published by one anilox rolls manufacturer that, in the attempt of promoting their technology, depicts dot dipping as an industry myth and illustrates flexo users, who believe that this problem exists, as troglodytes… “The industry myth that dot dipping is occurring within the anilox cells is impossible. Physics […]

Can you recognise the cause of dirty printing in highlights?It is important to understand wether the issue is related to dot dipping, thus plate-to-anilox ratio, wrong metering of the anilox surface or other causes.What is visible on the printed product is a generally a dirty aspect that forces to repeated stops for plate cleaning and

Do you know how to quickly convert your anilox rolls screen-count (cell count) and volume values between metric and imperial unit measurements? You can use these formulas: For volume: Volume in cm³/m² = Volume in BCM/in² x 1,55 (*)Volume in BCM/in² = Volume in cm³/m² ÷ 1,55 (*) 1,54899999999999 rounded to 1,55 For screen-count: Screen-count in c/cm = Screen-count in cpi ÷ 2,54Screen-count in cpi = Screen-count in c/cm x 2,54

Dot dipping describes the condition whereby the smallest dots on a flexo plate dip into the cells of the anilox roll when forced by the impression between anilox and plate. Some dots of the plate, dipping in the cells, will carry more ink than what was expected, resulting in dirty printing in highlights, typically seen
