The terms, from the factory floor rather than the dictionary
Each term with a definition that stands on its own, then how we do it at Tamm, or that we do not. If you read a word in the guide and did not know it, it is here.
36 terms
- Print on demandPrint on demand, POD
- A selling model where an item carrying a design is listed in a store and is not printed or shipped until a customer orders and pays.

- Direct-to-film printingDTF
- Printing the design onto a film and heat-pressing it onto the fabric with an adhesive layer, so polyester, blends and dark garments take it.
- SublimationSublimation
- Transferring dye by heat into a white polyester-coated surface until it becomes part of it; the method for mugs, mouse pads and metal prints.
- Screen printingScreen printing
- Printing that pushes ink through a separate screen per colour, so it costs a lot to set up and little per piece once the run is in the hundreds.
- EmbroideryEmbroidery
- Decorating a piece by stitching the design in thread from a digitised file; the stitch count sets the cost and gives a logo a raised finish.
- BlankBlank
- The product before printing: a plain tee, a white mug or poster stock, whose material, weight, cut and sizes decide what can be printed on it.

- The file a factory reads before it quotes: the drawing, measurements per size, fabric, thread, labels and packaging, with no question left.
- Size chartSize chart

- Woven labelWoven label
- A woven cloth strip carrying the brand name, sewn into the neck or the side, and what tells a branded piece from a printed blank.
- Cut and sewCut and sew
- Making the piece from raw fabric: cutting it to the pattern and sewing it, so the cut and the fabric are yours rather than a blank supplier's.

- White labelWhite label
- A ready-made product one factory makes and several brands sell under their own names; the piece is shared and only the name is yours.
- Private labelPrivate label
- A product made to one brand's specification and sold to no one else; the cut, fabric and label are its own, for a minimum, a sample and time.
