How Jersey Printing Works: Names, Numbers and What You Get

The three ways a name and number goes on

Almost every printed shirt you can buy uses one of three methods. They differ in how the design attaches to the fabric, which is what decides how it looks, how it feels and how long it lasts.

• Heat-pressed vinyl — Cut to shape, bonded with heat and pressure — fast, light, the usual replica finish
• Sewn tackle twill — Layers of fabric cut and stitched on — the most durable finish, and the heaviest
• Sublimation — Dye fused into polyester — nothing to lift, unlimited colour, polyester only
• Back number size — 10 inches adult, 8 inches youth
• Letter height — 2–3 inches for an adult name
• Placement — Number 2–3 inches below the collar seam, name 1–2 inches above the number

Heat-pressed vinyl is the method behind most replica and fan shirts. A pre-cut set is placed on the shirt and bonded under heat and pressure. It is quick, keeps the shirt light, and looks clean — the reason club and league replica ranges use it.

Sewn tackle twill is what people mean when they say a print looks professional. Layers of fabric are cut to the shape of each letter and number, then stitched onto the shirt. It survives heavy use, and the texture is unmistakable — but it adds weight and takes longer to make.

Sublimation skips the idea of applying anything at all. The ink is turned to gas with heat and bonds into polyester fibres, so the design becomes part of the shirt. There is nothing to lift, and no limit on colours — but it only works on polyester, not cotton.

What you get on a replica versus an authentic shirt

Replica shirts almost always use heat-applied vinyl or a transfer sheet: durable, inexpensive at scale, and light enough not to change how the shirt hangs. Match-spec and authentic shirts often use thinner, more flexible heat-sealed sets designed for perforated performance fabric, and on retro reissues you will find sewn-on twill or flock instead — heavier, and much harder to fake convincingly.

Number and name sizes, and where they sit

Placement is more standardised than most buyers expect, and it is worth knowing because a misaligned print is the giveaway that something was produced in a hurry. Numbers sit 2 to 3 inches below the collar seam and are centred across the back; the name sits on a matching nameplate 1 to 2 inches above the number.

Reading a nameplate: contrast and character limits

High contrast is the rule — white on a dark shirt, dark on a light one — so the name reads from the stands and from a photo. Font weight matters too: heavy strokes look right on a large back number and crowded on a small sleeve number.

The nameplate has a fixed physical width, which is why very long surnames get compressed to fit. If the name you are ordering is close to the limit, that is the one detail worth checking before you pay, because a squeezed name is hard to un-see once the shirt arrives.

Looking after a printed shirt

Heat is the enemy, not wear. Wash cool and inside out, keep the shirt out of a hot dryer, and never iron over the print — if you must iron, press the reverse of the fabric. A correctly applied set holds for seasons under those conditions.

Telling a genuine print from a fake

Four checks do most of the work: the weight of the strokes, the spacing between letters, the edges of the cut, and the period the font belongs to. Official sets use fixed kerning and clean cut lines, and the font acts as a date stamp — a current-season font on a ten-year-old shirt means the print was added later, if the shirt is genuine at all.

Genuine sets also feel supple. Cheap vinyl feels like plastic sheeting and lifts at the corners long before a properly pressed set would.
