Open the CIPO recordAbstract From the Canadian patent
An inking arrangement for printing, machines in which ink is supplied to the plate surface by means of ink form rollers. The inking arrangement comprises a roller train constituted of only a plurality of rollers each having its surface layer made of a single nonmetallic material or a mixed material, containing a non-metallic material as a base material, the rollers being successively arranged in contact with or in close proximity to each other. Thus, it is possible to obtain an excellent ink transfer condition and hence possible to prevent occurrence of the roller stripping phenomenon, which is likely to occur in offset printing process, for example.

Why it's free to use
- Filed January 25, 1990 and granted March 12, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 25, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 25, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
