A practical production route
Use the eight stages below to compare the complete route for your product, from preparation and pack handling through to dispatch. For screen-printing ink, the critical issues are vapour ignition, static discharge, spills, worker exposure and incompatible materials.
Define the product window
Measure the production range for screen-printing ink: fill volume or weight, density, viscosity or flowability, temperature, largest inclusion, foam, chemistry and shelf-life process. Select equipment against the worst case, not the easiest sample.
Prepare and feed consistently
Prepare screen-printing ink to a repeatable specification and supply the filler through bonded and earthed closed transfer with vapour management. Control batch-to-batch variation and avoid long, restrictive or difficult-to-clean pipework.
Apply the required treatment
Complete a hazardous-area and ignition-source assessment for screen-printing ink. Include bonding, earthing, extraction, spill control and suitable electrical or pneumatic construction.
Prepare the empty pack
Inspect empty approved plastic bottles for damage, contamination and dimensional variation. Rinse, air-clean or sterilise only where the product risk assessment and packaging specification require it.
Fill accurately and cleanly
Use a ATEX-assessed gravity, pump, peristaltic or flowmeter filling system. Classify the area and select electrical, pneumatic and mechanical equipment accordingly. Set the nozzle and container handling so the outside of the approved plastic bottles remains clean for closing and labelling.
Close or seal the pack
Apply compatible screw caps with repeatable torque or force. Include cap/closure presence detection and a routine check of opening performance, leakage and tamper evidence.
Label, code and verify
Apply wrap-around, front-and-back, top or tamper-evident labels as required by the approved plastic bottles. Add batch/date coding and use vision or barcode checks where label mix-up is a material risk.
Inspect and pack for distribution
Check fill quantity, pack integrity, code and presentation before accumulating or case packing. Confirm the finished approved plastic bottles survives handling, sleeve wrapping, case packing, palletisation and transport.
Equipment options for screen-printing ink
These machine types provide an initial route. Dose range, contact materials, output, utilities, change parts and controls should be agreed after a representative product and pack trial.

Product behaviour
Test viscosity, density, foaming, particle size or flowability using production-representative screen-printing ink. Classify the area and select electrical, pneumatic and mechanical equipment accordingly.
Fire and explosion safety
Complete DSEAR/ATEX assessment where applicable, remove ignition sources, provide bonding and earthing, and select extraction and equipment for the classified zone.
Cleaning and changeover
Plan for safe solvent recovery, ventilation and line clearance under an approved procedure. Confirm recovery, flushing, allergen or chemical segregation and safe disposal before purchase.
Pack validation
Run the actual approved plastic bottles and compatible screw caps through filling, closing, labelling and transit tests. Supplier drawings alone do not show real production variation.
Selecting equipment by weekly throughput
| Weekly volume | Typical equipment level | Planning approach |
|---|---|---|
| Under 500 | Desktop or manual-assist | Prioritise low changeover time, flexible tooling and safe repeatability. |
| 500–2,000 | Compact semi-automatic | Separate filler, closer and labeller can provide a practical step up without a full conveyor line. |
| 2,000–10,000 | Two-head or compact inline | Use controlled product feed, powered conveyors and automatic closing or labelling where labour is the constraint. |
| 10,000+ | Multi-head automatic line | Balance every station, include accumulation and specify inspection, rejection and end-of-line handling. |
Prove the line with your product and packaging
The most useful test uses the final screen-printing ink, approved plastic bottles, compatible screw caps, label and code. Include the most difficult size or formulation, not only the easiest product.
Discuss this applicationCommon questions about filling screen-printing ink
What filling machine is best for screen-printing ink?
A ATEX-assessed gravity, pump, peristaltic or flowmeter filling system is the usual starting point because screen-printing ink behaves as a flammable formulation requiring hazardous-area review, ignition control and appropriate extraction. The actual choice depends on dose, temperature, inclusions, required accuracy, cleaning regime and output.
Can screen-printing ink be filled into approved plastic bottles?
Yes, provided the approved plastic bottles, compatible screw caps and product are compatible. Test dimensional variation, fill temperature, headspace, leakage, closure performance, label adhesion and distribution before specifying the line.
Should screen-printing ink be filled hot or cold?
Keep screen-printing ink within the supplier safety and process specification. Do not add heat without a formal compatibility and hazard review of the product, vapour, equipment and approved plastic bottles.
Does screen-printing ink need ATEX-rated filling equipment?
Possibly. The answer depends on flash point, vapour generation, ventilation and the hazardous-area classification. A DSEAR assessment should define the required ATEX category and operating controls.
How should approved plastic bottles be closed after filling screen-printing ink?
Apply compatible screw caps with repeatable torque or force. Include cap/closure presence detection and a routine check of opening performance, leakage and tamper evidence.
What output can a screen-printing ink filling line achieve?
Output depends on dose size, pack handling, fill time, closure method, cleaning and operator loading. As a planning guide: desktop equipment suits under 500 packs/week, compact systems 500–2,000, two-head lines 2,000–10,000 and multi-head systems 10,000+.
What samples are needed to test screen-printing ink?
Supply representative screen-printing ink, the complete approved plastic bottles, compatible screw caps, labels and any coding specification. Include the full product range, especially the highest viscosity, largest inclusion or most difficult pack size.
