Why Offset Press Choice Changes Packaging Colour
The same artwork prints differently on different presses. What Heidelberg offset equipment and instrument-based colour control actually change about a packaging run.
Colour is a process, not a setting
Two suppliers can print the same file and produce noticeably different colour. The difference is rarely the ink brand. It is the press, the calibration discipline and whether the printed sheet is measured or judged by eye.
What good colour control actually involves
Reference standards held against Pantone cards, not memory
Density measurement through the run rather than at the start only
An experienced pressman reading the sheet as it comes off
Instrument checks on the finished product, not just the press sheet
Equipment differences that show up on the shelf
Sheet size, format and automation determine how consistently a press holds register and colour across a long run. Automatic plate change and multi-format capability matter when a programme spans several SKUs with different sheet sizes.
Measuring the finished product
Press-sheet colour and finished-box colour are not the same measurement. Lamination, foil and coating change how the surface reflects light, so colour should be verified on the finished article with instrumentation rather than assumed from the press sheet.
What to ask a supplier
Which presses will actually run my job
How colour is measured, and against what reference
Whether finishing effects are accounted for in the colour check
What happens if a batch drifts from the approved proof
Consistency across repeat orders
The real test of colour control is order three, not order one. Ask how reference sheets, ink records and approval files are retained so a repeat run matches the original.
