A Solvent Laminator, a 30-Day Inspection, and a Thin Quote
A small printing unit in Lucknow occupies a 12 m x 8 m shed shared with paper storage and a guillotine. The owner wants to add a second-hand two-colour offset press and a solvent-based thermal laminator to win a contract for 50,000 A5 leaflets, laminated one side, at Rs 1.10 per leaflet. The lamination quote must include film, solvent adhesive, electricity and labour. Current setup: one exhaust fan, solvent wash kept in open 20-litre drums, no eyewash, workers use cotton gloves, and waste solvent is poured into the drain after settling. The press would run near the paper stacks; the lamination unit needs 6 kW. The owner asks whether to accept the job, what to charge, and what must be fixed before installation. The local inspector has scheduled a visit in 30 days.
1. Identify the safety and environmental non-compliances and prioritise them with controls. Include solvent storage, ventilation, PPE, waste, fire and layout.

The open 20-litre solvent drums are the highest priority: they release flammable vapour, expose workers and contaminate the air. Replace them with closed, labelled safety containers in a bunded, ventilated store away from ignition sources. The single exhaust fan is inadequate for a solvent laminator; install local exhaust ventilation at the coating and drying points, with make-up air, and check that the fan is rated for flammable vapour. Cotton gloves absorb solvent and hold it against the skin; switch to nitrile gloves, goggles and suitable respiratory protection, and provide an eyewash within reach.
Waste solvent poured into the drain is an environmental offence. Collect it in labelled closed containers and use a licensed waste contractor, with manifests. Keep paper stocks away from the press and laminator; paper is a high fire load. Provide fire extinguishers suitable for solvent fires, no-smoking signs, and electrical inspection for the 6 kW load. Train workers on safety data sheets, spill response and emergency shutdown. Prioritise in this order: eliminate ignition and exposure, contain vapour, protect workers, manage waste, then improve layout.
2. Build a cost check for the lamination job. What cost elements are missing from the owner's Rs 1.10, and how would you decide whether to accept?
Read the worked answer
The owner has listed film, solvent adhesive, electricity and labour, but a quotation needs more: machine depreciation or hire-purchase instalment, maintenance and spares, setup and make-ready waste, film trimming waste, rejected leaflets and rework, packing, transport, supervision, rent and overhead, financing cost, and profit. Also include the cost of compliance: ventilation, PPE, waste disposal and training. Without these, Rs 1.10 may look profitable when it is not.
Use a simple build-up. A5 area is about 0.031 m2; 50,000 leaflets is about 1,550 m2 of film. If film costs Rs 8/m2, that is about Rs 12,400, or Rs 0.25 per leaflet. Add adhesive, power at 6 kW for the run, two workers, 5-10% waste, depreciation and overhead. If the direct cost is Rs 0.70 and overhead 15%, the break-even is about Rs 0.81; at Rs 1.10 there is a margin, but only if waste and downtime are controlled. If the calculation leaves less than 10% net margin, reject the price or re-quote. Decide on full cost, not on the owner's four-line list.
3. Should the owner accept the job and install the equipment before the inspection? Advise on sequence and documentation.

No. Installing a solvent laminator before the ventilation, storage and waste arrangements are in place creates an immediate fire, health and environmental risk and will fail the inspection. The inspection in 30 days is an opportunity, not a deadline to beat. Sequence the work: first fix housekeeping, close the drums, remove waste solvent through a licensed contractor, provide PPE and eyewash, and document the changes. Then obtain a quotation for local exhaust ventilation and fire precautions, confirm the electrical load, and apply for any required consent or registration. Install and commission the laminator only when the controls are working, then train operators and record the training.
For the customer, either outsource the laminating temporarily or offer a start date after compliance is verified; do not promise delivery on equipment that is not legal to run. Keep a file with safety data sheets, waste manifests, ventilation commissioning results, training records and the inspector's correspondence. If the customer will not accept the later start date, decline the job. A 50,000-leaflet order is not worth a shutdown, a fine or a fire.
