SACMI Imola S.C. of Italy, a division of the Sacmi Group have released the COLORA CAP on-cap digital printing solution that provides high resolution for the decorating of PE plastic caps for bottles and wide mouth containers.

The caps surface are pre-treated with a plasma and corona treatment to ensure they have ink adhesion and then transfer to the print heads with 1000 nozzles in two rows printing with a resolution of 360dpi x 360dpi at a speed of up to 600 cpm (for a 29mm dia cap) using CMYK colour technology. Drying is inline using a UV curing station and an integrated CVS Vision inspection system ensures in-line quality checking and rejection of defective parts. Cap size range is from 20mm dia up to 70mm dia with size and image changeover achieved in minutes.

The COLORA CAP provides companies with a competitive market advantage as they can brand their caps/lids for targeted promotional campaigns with short runs. The process developed by SACMI enables manufacturers to use high-definition digital images, importing them directly into the printing system in just a few minutes, and then starting a new production batch without any format changeover costs such as expensive colour printing plates. It also has the ability to print consecutive images to mix the designs throughout batches.
