A mounting device for holding a hollow cylindrical object, particularly a screw cap, in a printing system, comprises a support member, and a mandrel for receiving a hollow cylindrical object arranged at the support member, and a heating device for heating the hollow cylindrical object mounted at the mandrel. A printing system for printing on hollow cylindrical objects, preferably screw caps, comprises at least one mounting device, and at least one printhead configured to print on surfaces of cylindrical objects, preferably screw caps.

A production line is for aerosol containers (AC) whose exterior surface is printed with inks in a predetermined pattern to form a desired design including both imagery and graphics. The line includes an inking station and a varnish application station through which aerosol containers successively pass. Inks are applied to containers at the inking station and a varnish to the inked exterior of the container at the varnish station. A LED light module (12) installed between the ink station and varnish station emits a light within a predetermined frequency range onto inked containers. The temperature produced by the LED light source is cooler than that of Uv light sources that could be used for the same purpose. The exterior surface of finished containers exhibit no lapping or discolorations and have improved scratch resistance.

A printing technique is presented for efficiently printing (i.e. with production lines rates at high resolution and high accuracy) on outer surfaces of a plurality of objects passing in an optimized stream through a printing route/zone. According to this technique, at least one array of printing head units is provided being configured to define at least one printing route along a printing axis, where the at least one printing route is a substantially linear segment of a closed loop lane along which the objects are progressing.

An apparatus (200) and method for preparing a cylindrical object having a protective surface coating, such as a necked can (100), for decorating thereon using a printing technique. According to the method, a primer is applied onto the surface coating, and the primer is then dried to form a surface for decorating the object. The apparatus comprises a priming station (260) for applying a primer onto said surface coating, and a drying station (270) for drying the primer.

In a forward movement, an article is conveyed to a printing device via a transfer position while being kept mounted in a first holder for printing by the printing device. The article is returned to the transfer position together with the first holder after printing. An article to be printed after the above article is mounted into a second holder in parallel with at least a part of the forward movement, the printing and a return movement. This is capable of printing on the articles in a short throughput time also when the articles are those having a three-dimensional shape such as bottles and in-vehicle components.
