A machine for digital printing on tape, which comprises a frame that supports elements of entraining at least one tape along an advancement path and is provided with at least one printing assembly, which comprises at least one ink-jet printing head; downstream of the printing assembly, along the advancement direction of the tape, there is at least one assembly for drying the inks applied to the tape; the drying assembly comprises a temperature-adjustable drum for supporting and entraining the tape, adhesion elements adapted to allow the retention in adhesion of the tape on the outer lateral surface of the drum, and hot air emitter elements which face at least one portion of the outer lateral surface of the drum.

It is disclosed a substrate compactness detection method for a printer wherein the printer comprises a roller to receive a substrate roll and a media advance mechanism to receive a substrate from the substrate roll, the method comprising: determining a substrate thickness; advancing the substrate for a length; measuring an angular displacement of the roller caused by the advancing of the substrate; determining the substrate roll radius by using the length and the angular displacement; and calculating a compactness parameter in view of the substrate roll radius and the substrate thickness.

Aspects of the present disclosure relate to methods and apparatuses for printing and curing energy curable inks printed on a substrate having an onset temperature T.sub.onset (C). The printing systems may include a printing station and a light source. During operation, the printing station deposits energy curable ink onto a first surface of the substrate to define a printed region, and the light source directs ultraviolet light onto the first surface of the substrate to define an illumination zone on the first surface of the substrate. The substrate is advanced in a machine direction to advance the printed region through the illumination zone to cure the energy curable ink. While the printed region advances through the illumination zone, the ultraviolet light heats the substrate from an initial temperature T.sub.in (C) entering the illumination zone to a maximum temperature T.sub.max (C), wherein T.sub.max (C)T.sub.onset (C).
