Hidden Costs in Coding and Marking

A coding printer quotation shows the machine price and, if you ask, the price of ink or ribbon. Almost everything else that determines what the printer costs you over its life is missing from that page. These are the costs to put on the table before you sign.

1. Time-driven consumables

Some consumables are used up by running time, not by printing. The clearest example is CIJ make-up (solvent) fluid: it evaporates whenever the printer is running, whether it is printing or idling. In the calculator's default CIJ example, make-up costs ₹4,550 a month while the ink itself costs only ₹501 — nine times more — because the line runs 12 hours a day. Buyers who compare only ink prices miss this entirely.

2. Wear parts that are not called consumables

• TTO printheads wear in proportion to how many kilometres of ribbon pass over them. In the default TTO example, ribbon costs ₹26,000 a month and printhead wear adds another ₹7,583 — about 23% of the consumable bill — even though no printhead appears on a monthly invoice.
• CIJ nozzles and filters, TIJ cartridges (which include the printhead), and laser sources all have finite lives that belong in the total cost.

3. Downtime

Every hour the line is stopped because the coder failed, clogged or needs a changeover is lost production. Downtime cost = hours of unplanned stoppage per month × cost per hour of lost output. In the default CIJ example, four hours a month at ₹2,500 an hour is ₹10,000 a month — almost twice the entire consumable bill.

4. Rejection and rework

A missing, smudged or unreadable code can mean the product cannot ship. Rejection cost = rejection rate × products per month × cost per rejected product. Half a percent of 5,20,000 prints at ₹3 each is ₹7,800 a month. For pharma, food export or GS1 barcode applications, the cost per rejected unit — and the compliance risk — can be far higher.

5. Operator dependency

Technologies that need frequent adjustment, cleaning or troubleshooting tie up skilled operator time. A machine that only one person on one shift can keep running is also a resilience risk.

6. Technology-specific extras

• Laser on many plastic films needs a laser-reactive additive or coating to produce a visible mark.
• Untreated plastics may need corona treatment or a primer for ink to adhere.
• Barcode applications may need verification equipment to prove code grade.

How much does it add up to?

In the calculator's default CIJ example, the costs above that are typically missing from a quotation — make-up and cleaning fluid, downtime and rejection — total ₹22,650 a month, or 33% of the full running cost. That is before counting the operator.
