In many printing plants, ink temperature is treated as an operational variable rather than a business variable. Ink temperature rises during long runs, peak summer conditions, or high-speed production. Operators compensate by adding solvent, aiming to keep ink viscosity and density within limits. The press keeps running—but at a cost that rarely appears on operational dashboards.
Ink temperature stabilisers change this dynamic. They bring predictability to ink behaviour and, more importantly, discipline to ink consumption. Using ink temperature stabilisers maintains production efficiency – and at the same time, improves the bottom line.
How ink temperature control reduces ink consumption and slashes costs
Ink viscosity and density are temperature dependent. As ink warms up, solvent evaporation increases, leading to viscosity and density change. Operators respond by adjusting formulations mid-run, adding some more solvent.
A stable ink temperature keeps ink viscosity and density steady, from the first reel to the last. Printers and converters that install ink temperature stabilisers, see a measurable reduction in ink and solvent usage since less compensation is required during production.
There are many other savings too! Unstable ink temperatures lead to shade variations and higher rejection rates, and inconsistent print quality across batches. They also increase solvent usage, elevating odour levels, increasing fire risk, and impacting operators’ health. Over time, these issues translate into lost production hours, hazards, customer complaints, and lower asset utilisation—costs that are rarely attributed back to ink temperature.
From a financial standpoint, even a modest reduction in solvent consumption has a multiplier effect. Lower solvent consumption reduces material costs, while improved consistency reduces downtime and rework. The combined impact often delivers savings across procurement, operations, and quality.
Calculating ROI for an ink temperature stabiliser: a real-world case study
The return on investment is straightforward. Key inputs include annual ink consumption, average ink cost, solvent usage, and rejection rates attributable to colour or density variation.
Our customers have observed up to a 30% reduction in solvent consumption after using AxisValence make-Valflow ink temperature stabiliser. Most plants recover the cost of an ink temperature stabiliser within 12 to 18 months. In high-volume operations and solvent based printing environments, the payback period can be even shorter due to reduced ink loss and higher press efficiency.
An example from a leading flexible packaging printer running rotogravure presses proves this point. This converter faced rising solvent cost and inconsistent colour across long runs. By installing ink temperature stabilisers on each print station, the plant achieved stable temperature throughout production.
Within six months, solvent consumption dropped by approximately 30%. The investment paid for itself within a year, while customer rejections and material waste continued to fall beyond the payback period.
A decision worth revisiting
Ink temperature control is not an engineering upgrade. It is a financial decision that affects margins, consistency, and operational confidence. For leaders focused on sustainable profitability, controlling ink temperature is a simple step with a measurable return.
