Application split
A3 is a sheet size, 297 mm by 420 mm, and it is not automatically the printable area of a shirt machine. Use this page to turn the job, the room, and the utilities into questions before any factory is asked whether an a3 dtf printer matches that job.
Pair this with the sale configurations and the small-business preparation so the format question does not get lost in a model name.
Whether each item is required depends on the proposed model. Leave a cell blank when the datasheet has not been read yet. Do not copy a value from a different manufacturer page into the brief.
Record volts, hertz, phase, and the breaker already on the wall. A 110 V convenience outlet and a 220 V machine are not interchangeable. Ask for the full-load current on the exact model, with the powder heater on if that heater shares the circuit.
Powder and a heat press add heat and fine particles. Note ambient temperature and whether the room already has extraction. Noise level, if the buyer has a limit, should be requested with the distance at which it was measured.
State if the RIP must see the printer on a LAN, and which file types the art team will send. A control interface that needs a dedicated computer is an accessory line, not a footnote.
Machine length and width are not the working envelope. Add service access in millimeters on the side where film or shirts are loaded. Include the press if it must sit in the same bay.
Door width, elevator, and floor rating decide whether the crate can reach the room. Write the US destination down to the dock or the suite. Inside delivery is a freight option, not a default.
Who wipes the head, who stores ink, and what spare parts list should arrive with the machine. A preventive maintenance interval belongs to the supplier document for that model.
A standard A3 configuration can reduce the document set when every graphic fits inside 297 mm by 420 mm and the buyer accepts the stated resolution. An application-specific platen or a wider roll is the other side of that choice when shirt graphics, all-over prints, or gang sheets exceed that sheet. Neither side is a quality ranking. It is a fit question. Put the chosen side in the brief so a lower purchase price on a smaller width is not compared with a wider machine as if the scope matched.
The same split applies to lifecycle scope. A low equipment price is useful when film, powder, ink, press, freight, and commissioning are truly the same on every reply. If they are not, the delivered cost is the comparison, and the missing lines should stay visible. Headline dpi or shirts per hour should carry the test file, the media, and whether white ink was printing. That is the difference between a screening number and a number a production lead can plan around.
Ask the supplier to label each dimension. A machine can occupy more floor than its print area, and a roll printer can print wider than an A3 sheet while still being marketed near that phrase. Your brief should quote the dimension you need, with the unit.
Write shirts or sheets per hour and hours per day as targets, then ask which of those the supplier will confirm. Duty cycle language from welding equipment does not transfer. For this printer, duty means the run pattern and the maintenance pauses the supplier states.
You may add a target budget in USD or another currency, per printer or for the whole order, including or excluding the press. If you have no figure, say the budget is still open. Supplier preference can stay undecided while you compare scopes.
Datasheet, room sketch, ink SDS, and a sample graphic are typical gaps. List them as open. The bundle guide and the procurement note show how to request model-tied files without treating a public product page as your specification.
