Procurement

What to Ask Your Coating Supplier Before Your Next Run

Before you approve a new coating chemistry for production, five technical questions can save significant waste and downtime. Viscosity drift, pH control, and substrate compatibility are non-negotiable starting points. A supplier unwilling to provide batch-certified TDS documents is a red flag on any offset or UV line.

Ask specifically about gloss performance after rewetting, cold-seal compatibility if applicable, and whether the product has been tested at your target press speed. A good supplier will answer these without hesitation and provide documented batch test results on request.

Maintenance

Why Roller Maintenance Can Save You Thousands in Print Waste

Glazed or swollen rollers are among the leading causes of unplanned downtime and colour inconsistency on offset presses. A structured roller care programme using the correct de-glazing chemistry and wash sequence can extend roller life by two to three times while halving makeready waste on the first form.

The economics are straightforward. A set of replacement rollers for a four-colour press can cost more than a year of proper roller care chemistry. Monthly de-glazing, combined with the correct fountain solution balance, is the single highest-return maintenance activity in the pressroom.

Specification

Water-Based vs UV Coatings: Which Is Right for Your Job?

The choice between water-based and UV coating is rarely straightforward. Substrate porosity, inline vs offline application, drying capacity, and end-use requirements all influence the decision. For food-adjacent packaging, water-based low-migration chemistries frequently outperform UV on compliance grounds, even where UV delivers better gloss figures.

Speed is another factor. UV delivers instant cure and faster throughput on a dedicated offline coater, but water-based inline coating can eliminate a separate coating pass entirely. The right answer depends on your press configuration, your customer specifications, and your substrate stack.
