Screen Printing London and Other Print Methods
Custom Screen Printed T-Shirts and Bulk T-Shirt Printing
Screen printing gives the boldest and longest-lasting result on larger t-shirt printing orders, with colour-matched inks and speciality finishes such as puff, metallic and fluorescent. Alongside screen printing for brands across the UK, we offer DTG, DTF, transfer printing and sublimation, so each design gets the method that suits it. For bigger quantities, our bulk t-shirt printing service keeps unit costs down without cutting corners on quality.
DTG Printing and DTF for Short Runs
We provide DTG printing in London. DTG gives detailed, full-colour prints straight onto cotton, with orders from 10 units, sampling available and delivery across the UK, which suits short runs and on-demand jobs. We also offer DTF, vinyl and speciality transfers with quick turnaround, and we’ll advise which method fits your design and quantity.
Embroidery & Headwear
Embroidered caps, beanies and hoodies give a brand a timeless, long-lasting finish. We embroider flat and 3D puff logos on headwear, garments and accessories, from retail pieces to workwear, with woven and leather patches as other great options. Get in touch to talk through your project.
Art Print Editions
Alongside garments, we screen print limited art print editions for illustrators, artists, exhibitions and bands, including some well-known artists and illustrators. Screen printing on paper holds fine detail and strong colour, which suits numbered editions, gig posters and tour merch, and commands a higher selling price than digital alternatives.
Live Printing at Events
Our t-shirt printing also comes to your event as a live print activation, where guests can customise garments on the spot. We run live printing at product launches, trade shows, festivals and workshops, at venues across the country and overseas, with set-ups to suit different spaces and budgets. We also print and embroider many other products, so get in touch to discuss your Live Print activation.

Ordering Information
Print Methods & Quality
Different print methods suit different designs and quantities.
Screen printing is ideal for bulk t-shirt printing with fewer colours and bold print areas.
DTG works well for smaller runs and photographic or multi-colour artwork. DTF is a useful alternative on some garments.
Embroidery suits smaller designs on heavier garments, and vinyl works well for single-colour artwork on activewear and outerwear, or for names and numbers.
T-Shirt Printing Frequently Asked Questions
What is your minimum order quantity for t-shirt printing?
It depends on the method. Screen printing starts at 25 units (up to 4 colours, or 3 on dark garments), with 50+ units for higher colour counts. DTG, DTF, vinyl and embroidery start at 10 units. Sampling is available and charged at sample rates, and a minimum order value of £50 applies.
How long does a bulk order take?
Most orders are ready in 7 to 10 working days, and larger or seasonal orders can take up to 15.
- Rush orders may be possible on enquiry
- Lead times start after final specification approval
- Changes after approval may extend production time
Can you help with tight deadlines?
In some cases, yes. Rush orders depend on capacity, artwork readiness, and garment availability.
If you have a fixed deadline, let us know at enquiry stage and we’ll advise what’s possible.
How should artwork be supplied for printing?
We recommend supplying artwork as a press-ready PDF created from vector files where possible.
- Preferred formats: PDF, AI, EPS
- Raster artwork: minimum 300dpi
- Artwork should be supplied at, or close to, final print size
What are the maximum print areas?
It varies by method and garment size: screen printing up to 37 × 47 cm, DTG up to 49.5 × 64 cm (jumbo prints on request), embroidery up to 47 × 47 cm and DTF up to 37 × 50 cm. The actual size can change with the garment.
Which print method is best for our designs and quantities?
It comes down to quantity, artwork style and garment. Screen printing suits bulk orders with fewer colours and gives strong durability. DTG suits smaller runs, photographic artwork and complex colour. Embroidery works best for smaller designs with less detail, especially on heavier garments such as hoodies and polos. If you are unsure, we are happy to advise.
Do you source garments and other products as well as print?
Yes. Most orders use blanks from leading apparel brands, and we can find specific garments or other products on request, subject to availability.
Do you deliver nationwide and overseas?
Yes. We send t-shirt printing orders from London throughout the UK and abroad. Overseas costs vary by destination and order size, so please allow extra lead time.
What’s the difference between screen printing t-shirts and DTG?
Screen printing pushes individual inks through a stencil and is best suited to bulk orders with bold designs and fewer colours.
DTG (direct-to-garment) printing applies ink directly to the fabric using a digital CMYK process and works well for smaller runs and detailed, multi-colour artwork.
Do you offer samples or pre-production proofs before printing?
Yes. We can supply blank, printed, or embroidered samples. DTG and DTF samples are £30. You can also arrange a visit to see garments in person at our showroom in London.
- Blank samples are available to purchase on our website.
- Decorated samples are charged based on production time and setup.
- For custom orders, a final spec or proof must be approved before production begins.
Who do you work best with?
Brands, agencies and organisations that need dependable bulk t-shirt printing in London and consistent results. Very small one-off orders are less of a fit, but we are always happy to advise on the best approach.
