The creation of labels is a diverse field, adapting to a wide array of products and printing methodologies. Generally, labels fall into two primary categories based on printing technique: self-adhesive and non-self-adhesive. Self-adhesive labels are typically produced using flexographic printing, where labels are printed on a roll. Non-self-adhesive labels utilize offset printing equipment.
For flexographic label production, the initial investment should include a flexographic plate fabrication system. A computer-to-plate (CTP) system is recommended for directly transferring pre-press files onto photopolymer plates, improving accuracy and efficiency.
A flexographic printing machine is also essential. It should feature at least six color groups. Optimize productivity by selecting a machine with a maximum printing format that aligns with initial production estimations. This machine should be equipped for various finishing processes like UV varnishing, die-cutting, and metallic foil stamping.
For sheetfed label production, a sheetfed printing press with a minimum of six color groups is required. The maximum print format should be determined by thorough market research conducted before investment.
Complementary to the printing press, a guillotine with a maximum opening compatible with the printing machine’s format is necessary. Prioritize a guillotine with a broad format range to accommodate diverse label sizes. Programmability is crucial for increased productivity.
If the sheetfed printing press lacks UV varnishing capabilities, a separate UV varnishing unit is indispensable. This can be either a dedicated machine or an adaptation of a traditional sheetfed press, modified by removing the humidification unit and adding a UV drying system at the delivery end.
Furthermore, sheetfed label production benefits from a metallic foil stamping machine, which can be automatic, semi-automatic, or manual, depending on business scale and needs. For labels with non-rectangular shapes, a tunnel puncher is required. The maximum processing dimension of the puncher must align with the targeted market’s specific requirements.
