Folding cartons When it comes to packaging, the folding carton is the first choice. Manufacturers of three-dimensional packaging are supported by sophisticated software tools, and every folding carton printer offers the service of developing the "individual folding carton packaging solution" in close contact with end customers and advertising agencies according to systematic criteria: Is the packaged good solid in consistency and shape (folding carton with stabilizing structure required for the object), solid only in consistency (folding carton for grit) or liquid (folding carton for filling goods, e.g. beverage carton)?
Can the folding carton serve as primary packaging (packaged goods are only wrapped in the folding carton)? Or is it only the secondary packaging? (Packaged goods are additionally wrapped in the carton by primary packaging, e.g. bag, wrapper, bottle, tube, etc.)Can the carton and stabilizing packaging elements (e.g. pressed or thermoformed plastic parts) be combined in a single construct? (In this case, the folding carton blank contains stabilizing elements that are folded inwards.)Which packaging material (cardboard coated on one side, corrugated cardboard, composite material made of cardboard and aluminium foil) is most suitable? Which finishing options (varnishing, die-cutting, blind and foil embossing, perforating, window lamination) are available in the company and can be integrated as design or convenience elements (tear tabs, perforations, carrying handles, viewing windows)? design and constructionThe packaging designers use CAD software, e.g. AutoCAD or SolidWorks 3D-CAD, to design the folding carton body. The actual visual design - i.e. the application of brand features, inscriptions and advertising elements - is carried out using special prepress software. The workflow solutions from Artwork Systems (ArtPro, Nexus, Odystar Packaging) and Esko (Scope) are leading the way. Among other things, they allow
import the CAD data or you can generate it yourself (e.g. Esko ArtiosCAD), from which the subsequent cutting dies including perforation and groove lines are also generated;
the transfer of native illustration and layout information from publishing programs, e.g. Adobe Illustrator (80 % is used in packaging design) and InDesign, but in return also the enhancement of Illustrator with 3D simulation plug-ins (e.g. Esko DeskPack 3-dx);the integration, checking and editing of PDF files from publishing applications, possibly including packaging-specific PDF certification (Artwork PA:CT);the trapping of type and graphic elements;the distortion of design elements in accordance with a curvature of the packaging;if necessary repeating (panel copy) or interlaced repetition of the folding carton subject on the printed sheet or web section in order to make optimum use of the print format;Internet-supported collaboration (Artwork WebWay, Esko WebCenter).Finishing on topIn contrast to commercial printers, folding carton printers, like most other packaging printers, hardly suffer from economic downturns and reduced advertising budgets, because packaging is always needed. This certainty means that folding carton printers are more willing to invest in additional finishing technologies: there is a lot of inline technology on the printing presses, but there are also numerous systems that can be used offline. These options, which help companies to survive in the demanding market segment, will be presented in a later issue.
