Screen Printing T Shirts: Process, Inks and Order Planning

Screen printing t shirts is still the standard way to put a bold, durable design on a run of tees, because every colour is laid down as a layer of ink through a mesh stencil. This guide explains how the process works, which ink to choose, how to prepare artwork and how to plan an order, so you can brief a printer or factory with confidence. If you are still choosing between methods, our comparison of screen printing, embroidery and DTG is a useful companion.

What Is Screen Printing on T-Shirts?

Screen printing t shirts means pushing ink through a fine mesh screen onto the fabric, where a stencil blocks the areas that should stay clear. Each colour in the design needs its own screen, and the colours are printed one after another, so a three-colour logo means three screens and three passes. The ink sits on or in the surface of the fabric and is then cured with heat so that it bonds and survives washing.

The method suits designs built from solid, flat colours, such as logos, slogans, graphic illustrations and repeat text. It is less suited to photographic images with smooth gradients, which are usually better handled by digital methods such as DTG printing. Because the cost of preparing screens is paid once per colour, the method rewards repeat designs and larger runs.

1 screenNeeded for every separate ink colour in the design
Mesh countThe number of threads per unit of screen; higher means finer detail
Cure stepInk is heated to its cure temperature to bond to the fabric
Spot colourA solid, pre-mixed ink colour, often matched to a Pantone reference

Those four terms come up in almost every conversation with a printer, so it helps to know them before you brief anyone. The rest of this guide takes them in the order a job runs.

How Screen Printing T Shirts Works, Step by Step

A screen print job follows a fixed sequence, and knowing it explains why printers ask for artwork early and why changes late in the day are expensive. Artwork is separated into one layer per colour, each layer is output as a film or direct to screen, and the screens are coated with light-sensitive emulsion and exposed so the design is burned into the mesh.

From artwork to finished print

  1. 1Separate the coloursArtwork is split into one black-and-white layer for each ink colour.
  2. 2Expose the screensEach screen is coated with emulsion, exposed to light through its layer and washed out to leave an open stencil.
  3. 3Set up and registerScreens are mounted on the press and aligned so the colours land exactly on top of or next to each other.
  4. 4Print and flashA squeegee pushes ink through the mesh. A short flash cure can gel one layer so the next can be printed over it.
  5. 5CureThe print passes through a dryer or oven at the ink supplier recommended temperature and time.
  6. 6Check and packPrints are inspected for placement, coverage and cracking, then folded and packed.

Simplified. Equipment varies between automatic carousel presses and manual presses.

Registration, the alignment of one colour to the next, is the skill that separates a clean print from a blurry one. Designs with fine gaps between colours need tighter registration, so ask whether your artwork needs a small overlap, called a trap, between adjacent colours.

Screen Printing Inks: Plastisol, Water-Based and Discharge

The ink you choose changes how a print feels, how opaque it looks and how it behaves in the wash, so it deserves a decision rather than a default. Plastisol is the most common ink for screen printing t shirts, water-based inks give a softer feel, and discharge inks remove dye from the fabric instead of sitting on top of it.

Main screen printing ink types compared

Ink typeHow it behavesFeel on the shirtBest suited toWatch out for
PlastisolSits on the fabric surface and stays wet on the screen until heatedSlightly raised, rubbery layerOpaque colour on dark garments, bold logos, high-volume runsA heavy layer can feel stiff if printed thick or in large areas
Water-basedSoaks into the fibres and dries by evaporation, then curesSoft, almost part of the fabricLight-coloured or natural cotton shirts, large soft printsLess opaque on dark fabrics unless an underbase is used; screens can dry in the mesh
DischargeRemoves dye from the fabric and replaces it with pigmentVery soft, no raised layerDark cotton garments where a soft vintage look is wantedWorks only on suitable dyes and fibres; test on the exact fabric
Puff and specialtyAdditives make the ink expand or change its surface when heatedRaised, textured or metallic effectsAccent areas on a designNeeds careful temperature control; see our puff print guide

General characteristics of each ink family. Always confirm with the printer and the ink supplier technical data sheet.

Ask the printer to follow the ink supplier data sheet for curing temperature and dwell time rather than quoting a single figure, because the correct settings depend on the ink system, the garment weight and the dryer. An under-cured print can wash out or crack, which is among the most common causes of customer complaints on printed tees.

When Screen Printing T Shirts Is the Right Choice

Screen printing wins when a design is simple in colour count, the garments are produced in repeat quantities and the print needs to last. It loses when a design has many colours, photographic detail or a very small run, where the setup cost for each screen is spread across too few shirts.

Screen printing at a glance

Where it is strong

  • Strong, opaque colour, including light ink on dark fabric
  • Durable prints that survive repeated washing when cured correctly
  • Per-shirt cost falls as quantity rises, because setup is shared
  • Spot colours can be matched to a defined reference
  • Suits cotton, cotton blends and many polyester blends with the right ink

Where it is limited

  • Setup is charged per colour, so many-colour designs cost more
  • Photographic gradients need halftones or a different method
  • Very small runs can be uneconomic compared with digital printing
  • Colour changes after screens are made mean new screens
  • Polyester content may need low-bleed ink to control dye migration

As a rule of thumb, ask for a quote on both screen and digital printing for the same design at your intended quantity, and let the comparison tell you where the crossover sits. Printers set their own minimums and pricing, so we do not quote a number here.

Screen Printing vs DTG, HTV, DTF and Sublimation

Screen printing is one of five methods most brands consider for printed tees, and each has a different sweet spot. The comparison below is general, and the right choice depends on your artwork, fabric and quantity. For deeper reads, see our guides to DTG, heat transfer vinyl and DTF and sublimation.

Preparing Artwork for Screen Printing T Shirts

Good artwork preparation saves more money than any other single step. A printer can only reproduce what the file contains, so a low-resolution image or a design with too many colours will cost time or get rejected. The checklist below covers what to send.

Artwork checklist for a screen print

  • Supply vector files (such as an outlined PDF or SVG) where possible, with text converted to outlines
  • Reduce the design to the fewest solid colours that still look right
  • Name each ink colour and give a Pantone reference if exact matching matters
  • Avoid very thin lines and tiny gaps, and ask the printer for their minimum line weight
  • For halftones, ask what mesh count and dot size the printer prefers
  • State the print size and position in millimetres on a flat drawing of the shirt
  • Say whether the ink colour will sit on a dark or light garment, since dark garments may need an underbase

Minimum line weight and gap size depend on the printer and mesh, so confirm with them.

Our guide on how to design a t shirt for production walks through the wider design workflow, including fit, fabric and mockups. If you have photographic artwork, expect the printer to propose a halftone treatment or suggest a digital method instead.

Print Placement and Size for T-Shirts

Placement is part of the design, not an afterthought. The table gives typical size ranges used as starting points for adult tees, but proportions should always be checked against your size run, because a print that looks right on a medium can look oversized on a small and tiny on an XXL.

Typical placement and print size starting points

PlacementTypical print widthNotes
Left chest80–100 mmSmall logos; sits on the wearer’s left, roughly at chest-pocket height
Centre chest200–300 mmStandard graphic or slogan position, set below the neckline
Full front280–350 mmLarge graphics; check against the smallest size in the run
Upper back250–330 mmLarge back print, often set below the collar seam
Sleeve60–90 mmSmall logo or flag, kept clear of the seam
Back neck70–100 mmSmall label print or brand mark under the collar

Typical starting ranges for adult sizes; they vary by brand, fit and print method, and should be confirmed on a sample.

Many brands scale artwork by size group, for example one print size for small to large and a slightly bigger one for extra-large and above. Define this in your tech pack so every size looks consistent. For a boxy or dropped-shoulder fit, positions often need adjusting, as discussed in our boxy and oversized t-shirt guide.

Planning an Order and Checking Quality

Order planning starts with deciding how many colours the design really needs and how many garment colours you plan to print on. Each garment colour may need its own ink approach, particularly on dark fabrics, where a white underbase is often printed first. Quantities per design and per colour influence price, so many printers prefer to quote on total print runs rather than per shirt.

Quality checks on a printed run should be specified in advance. Look at placement against the agreed measurement from a fixed reference such as the neck seam, colour against the approved reference, coverage and edge sharpness, and a wash test on a sample for cracking, peeling or fading. Our AQL inspection guide explains how sampling plans are used to accept or reject a finished lot.

Common Mistakes in Screen Printing T Shirts

Most problems with screen printing t shirts come from a handful of repeat causes, and they are avoidable with a clear brief and a sample. The ones we see discussed most are choosing the print method after the garment has been bought, ignoring fabric content, and approving colours from a screen rather than a physical reference.

  • Printing on a fabric the ink does not suit, such as a polyester blend without a low-bleed system
  • Sending artwork with too many colours or hairline details that will not hold on the mesh
  • Approving the design on a mockup instead of a printed sample on the real shirt
  • Skipping a wash test, so cracking or fading appears only in customers’ hands
  • Forgetting to define print size by size group, which makes small and large sizes look inconsistent

Ask for a physical sample on the exact shirt and wash it before approving bulk, a step that fits naturally into working with a t-shirt manufacturer. If the design is a small logo rather than a graphic, embroidery may suit better, as covered in our polo shirt embroidery guide.

How Ruhrose Approaches Printed T-Shirts

Ruhrose develops jersey garments, including t-shirts, for UK buyers with production in Bangladesh. We treat print as part of the sampling conversation: we discuss artwork, fabric and print method together, produce a sample, and only then move to bulk. We do not quote prices or minimums on this page, because they depend on the design and the print method. If you are choosing the blank before the print, our fabric GSM guide is a good place to start.

FAQs

There is no single best ink. Plastisol gives strong, opaque colour and suits bold logos. Water-based ink feels softer and suits light shirts and large prints. Discharge suits dark cotton for a soft finish. Choose by the look and feel you want, then confirm with your printer.
A screen print can have as many colours as the printer has screens and press stations for, but each colour needs its own screen and setup. Most brands keep designs to a small number of solid colours to control cost, and move to digital printing for photographic artwork.
Send vector artwork, such as an outlined PDF or SVG, with colours named and Pantone references if matching matters. If you only have a raster image, supply it at high resolution and expect the printer to rebuild or simplify it before making screens.
Neither is better for every job. Screen printing suits repeat runs of designs with few colours and gives strong, durable colour. DTG suits small runs and detailed, many-colour or photographic artwork. Get quotes for both at your quantity and compare.
Common causes are under-curing, ink laid on too thickly, the wrong ink for the fabric, or a fabric that stretches more than the print. A wash test on a bulk-representative sample, and curing to the ink supplier data sheet, usually exposes the problem before bulk.
Yes, but polyester dye can migrate into the ink and tint it, especially pale colours on dark garments. Printers use low-bleed inks and test first. Tell the printer the exact fabric composition before they quote so they can plan the right ink system.
