Reverse order ink jet coders from Packserv Australia are helping manufacturers resolve a major dilemma faced universally.
Printing variable data onto laminated or glossy labels (including thick varnish finishes) was not successful with traditional methods of hot foil coding or thermal transfer printing during the automated packaging process.
Adding variable data to ‘hard to print/code’ labels whilst on the automated production line can be problematic because the label can't be marked once the container has been labelled.
Manufacturers who are working with ‘hard to print/code’ labels need to mark the labels in ‘reverse order for ink jet coding'. To enable this, the coder is placed in between the capping and labelling processes instead of at the end of a production line.
Ink jet coders use etching solvent and pigment based ink that etches into any surface or substrate allowing variable data to be successfully added onto any label before the label ends up on the container.
The coder prints onto the label whilst still on the label roll on the automatic labeller before the label reaches the container, using a signal from the conveyor to know where the container is on the line.
At over 500 impressions per minute, ink jet coders will far outrun hot foil coding and thermal print methods.
