Ink Printing

How Ink Printing Works

Ackley Hartnett ink printing systems use high-output rotogravure offset printing to transfer ink from an engraved printing roll to the product surface with precise control. Products are fed and oriented using patented handling technology to ensure accurate alignment before printing. Ink is applied evenly and consistently, producing durable, legible marks without compromising product integrity. User-friendly controls, quick changeovers, and easy cleaning support efficient operation across varying product runs.

A variety of colorful prescription pills and capsules, highlighting Ackley Hartnett capabilities, are spilled from a bottle onto a white background. The pills display different shapes, colors, sizes, and visible imprints or codes.

Key Benefits of Ink Printing

Exceptional Print Quality: Rotogravure offset printing produces sharp, repeatable graphics with clean edges and consistent ink transfer, even on curved or textured surfaces.
Accurate Product Alignment: Patented positioning technology ensures each product is properly oriented before printing, minimizing rejects and ensuring consistent registration from piece to piece.
Single- or Double-Side Printing: Systems support printing on one or both sides, in single or multiple colors, providing flexibility for branding, dosage information, or decorative designs.
High-Speed, High-Output Performance: Engineered for continuous operation, Ackley Hartnett ink printers maintain print quality at production speeds—ideal for both mid- and high-volume manufacturing environments.
Flexible Configurations: Modular designs accommodate a wide range of product sizes, shapes, and materials, with scalable options from R&D through full-scale production.
Integrated Vision Inspection (Optional): Vision inspection verifies print presence, position, and quality in real time, automatically rejecting non-conforming products to protect downstream processes.
