Abstract: The invention relates to a flexographic printer comprising: inner dividing means which, together with a surround casing, define first, second and third enclosures; and fluid circulation means which are used for the circulation of at least one fluid at a regulated temperature. The aforementioned enclosures are sufficiently closed off and insulated from one another and the fluid is circulated at a sufficient flow rate, such that the solvent vapour concentration in the atmosphere, originating from the ink, is below a lower pre-fixed explosion limit in at least the second and third enclosures which house means of actuating the rotation and movement of the cylinders and electric and/or electronic devices and/or elements associated therewith.
