中文Heidelberg has launched the CromaStar series of automated ink-blending systems, letting carton printers mix their own spot colours in-house instead of relying on external suppliers. Aimed squarely at folding-carton operations, the system is designed to eliminate supply chain bottlenecks in spot-colour production and enable “the intelligent production and delivery of spot colours directly in the print shop.”
The modular concept allows a tailor-made configuration for different production volumes, from manual batch preparation with the ChromaStar entry-level system to high-performance, highly automated solutions for industrial applications. The series comprises the X, S, M and P models, giving printers a scaling path that matches their actual throughput rather than forcing a one-size-fits-all purchase.
For carton printers, spot colours are both essential and troublesome. Brand owners demand exact, repeatable shades, yet sourcing custom mixes externally introduces lead times, minimum batch sizes and the risk of variation between deliveries. By bringing mixing in-house, printers gain control over timing and consistency, turning a procurement headache into a managed production step.
Heidelberg says CromaStar supports the safe and efficient processing of conventional, UV and low-migration Saphira inks for food and non-food applications. Precise dosing technology, short mixing times and high process reliability together deliver an efficient, resource-saving ink supply. That matters especially in food packaging, where low-migration formulations carry strict compliance obligations.
Integration is a core selling point. CromaStar can be used for both UV and conventional inks and, according to Heidelberg, “integrates seamlessly into the workflow.” The combination of Saphira Inks, Saphira Cloud, Saphira Check and Saphira Control “ensures end-to-end transparency, traceability, and consistent colour results.” A separate proof output supports colour-accurate communication throughout the process chain, so the colour defined at the start matches the colour produced at the end.
The business case rests on three pillars: higher productivity, reproducible colour and automation tailored to the printer’s needs. By mixing on demand, shops avoid tying up capital in pre-mixed inventory and reduce the risk of obsolete stock when a brand tweaks a shade. Faster turnaround on spot colours also strengthens a converter’s ability to meet tight carton deadlines.
Supply chain resilience is the quiet headline. External spot-colour suppliers have at times been a bottleneck, particularly during demand spikes or logistics disruption. An in-house blender insulates the print shop from those shocks, ensuring a critical input is always available on the production floor. For carton printers competing on lead time, that independence can be decisive.
Heidelberg positions CromaStar within its broader Saphira consumables and cloud ecosystem, which means the data around formulations, dosing and colour control stays connected. That traceability is increasingly valuable as brand owners request documentation proving colour consistency and material compliance across a run and across repeat orders.
The launch also reflects a wider industry move toward bringing more process control in-house. As margins tighten and customers demand faster, more customized work, printers are looking to own the steps that most affect quality and speed. In-house ink mixing is a natural extension of that philosophy, sitting alongside digital printing and automated finishing as a way to capture more value on the floor.
For carton converters evaluating the system, the modular range lowers the entry barrier: a smaller shop can start with the manual ChromaStar and graduate to automated models as volume grows, without discarding the underlying formulation knowledge. That scalability makes the investment defensible across a range of business sizes.
Ultimately, CromaStar is about removing a familiar friction point. By making spot-colour mixing precise, traceable and local, Heidelberg gives carton printers one less reason to wait on a supplier and one more way to promise customers exact, repeatable colour, on time, every time.

For carton printers competing on lead time, that independence can be decisive.
In food packaging especially, low-migration formulations carry strict compliance obligations, and CromaStar’s support for those inks, paired with Saphira Cloud traceability, gives converters documentation that brand owners increasingly demand. Colour consistency across repeat orders becomes a managed, recorded process rather than a hopeful repetition.
The launch also reflects a wider industry move toward capturing more process control on the floor. As margins tighten and customers want faster, more customized work, printers are bringing critical steps in-house. In-house ink mixing sits naturally alongside digital printing and automated finishing as a way to own more of the value chain and reduce dependency on outside vendors.
