Making something that isn’t listed? Brief it anyway, or start with a factory-ready tech pack.
Our calculator has no separate tank line, so plan on the t-shirt base. Screen print adds about €1.40 a unit, embroidery €1.80, a wash or dye treatment €2.50.
Costs are the base ranges from our free cost calculator: per piece, ex-factory, excluding VAT, at 300–500 units with mid-range fabric and standard complexity. Your tech pack sets the final quote.
A rib tank looks simple, but the rib, the armhole finish and the length do all the work. These are the points our team checks in your tech pack before a sample is cut.
