Carton Production

Carton Production starts with the design of the product, originating either with the printer or designers who send their work to the printer. The graphics are then transferred to a computer and from this a printing plate for each colour is prepared.

Many cartons can be printed on each sheet of cartonboard and so a layout is worked out to ensure that as little cartonboard as possible is left unused. This layout is also used to prepare the cutting and creasing forms that are used later in the production process.

Cartonboard in either sheets or reels, is loaded into the Printing machine and printed in one pass with each colour being added in turn. As well as the colours, a varnish is also usually printed after the colours. Digital printing although in its infancy, is still used in about half a dozen mills around the UK. Digital printing is used on flat surfaces for what is deemed by some to be greater clarity.

The sheets are then taken to a machine that cuts the cartons and also puts in the creases that enable it to be folded in a later operation. It is also possible to add embossing during this operation (when an indentation of a specific pattern is made on the paper). When the cartons have been cut and creased, they are moved through to the gluing line where the cartons are folded and glued. The cartons are then packed for shipment to the carton user who puts them onto their packing line for filling.
