Accepted File Formats

The format of your file affects the quality of your finished print. Vector files are always preferred — they can be scaled to any size without loss of quality. Raster files are acceptable if they meet our resolution requirements.

.AI
Vector

Adobe Illustrator — the ideal format for logos and artwork

.EPS
Vector

Encapsulated PostScript — universally compatible vector format

.PDF
Vector

PDF with embedded vectors — great for sharing designs

.SVG
Vector

Scalable Vector Graphics — ideal for web-exported logos

.PNG
Raster

Must be 300dpi+ at final print size. Transparent background preferred

.JPG
Raster

Must be 300dpi+ at final print size. No transparency support

Note: Files supplied from websites, social media, or Word documents are typically low resolution (72–96dpi) and are not suitable for print. If in doubt, send us what you have and we'll advise.

Resolution & Size

Resolution matters only for raster (pixel-based) files. Vector files are resolution-independent and scale perfectly to any size.

Minimum 300dpi at final print size — for screen printing, DTF and vinyl
Provide at actual size — don't scale up a small file; this doesn't add resolution
Check pixel dimensions — a full front print is typically 300–350mm; at 300dpi this is ~3540–4134px

Left Chest120mm100mm
Full Front300mm350mm
Full Back300mm380mm

Back Neck80mm40mm

Sizes vary by garment size. We'll confirm exact dimensions when we check your artwork.

Colour Modes & Matching

Colour accuracy starts with using the right colour mode for your chosen print technique. Using the wrong mode can cause unexpected colour shifts in the final print.

Screen Printing

Uses Pantone (PMS) spot colours. Each colour is a separate ink mixed to a precise Pantone reference. Provide Pantone references for exact brand colour matching. CMYK or RGB artwork can be colour-separated if Pantone refs aren't available.

Pantone CMYK

DTF & Vinyl Transfer

Uses CMYK four-colour process printing. Supply artwork in CMYK colour mode for the most accurate result. RGB files are accepted but may shift slightly during conversion — especially reds, blues and fluorescents.

CMYK RGB

Embroidery

Thread colours are matched to the Madeira or Isacord thread range. Provide Pantone references where possible and we'll select the closest available thread. Exact colour matching depends on thread availability — we'll always confirm before production.

Thread Pantone

Avoid pure RGB values: Colours like 255/0/0 red or 0/0/255 blue are outside the CMYK gamut and will print differently to how they appear on screen. If your brand uses specific RGB values, ask us to advise the closest achievable CMYK or Pantone equivalent.

Text & Fonts

Fonts can cause problems if they are embedded in your file but not installed on our system. The fix is simple: convert all text to outlines (also called paths or curves) before saving your file.

How to convert text to outlines

  • Adobe Illustrator: Select All → Type → Create Outlines
  • Inkscape: Select All → Path → Object to Path
  • CorelDRAW: Select All → Arrange → Convert to Curves
  • Affinity Designer: Select All → Layer → Expand Stroke / Convert to Curves

Minimum text sizes

  • Screen printing: 6pt minimum for solid text, 8pt for reversed text
  • DTF & vinyl: 5pt minimum for solid text
  • Embroidery: 4mm cap height minimum (approximately 11pt)

Tips for great results

Use bold, clean fonts for small text — thin or script fonts can lose detail at small sizes
Avoid very thin strokes — anything under 0.5pt may not reproduce clearly
Check that negative text (white on dark) has adequate letter spacing — tight text can fill in
For embroidery, avoid very thin letterforms — use fonts with a consistent medium weight
Always send us a visual proof (PDF or PNG) alongside vector files so we can confirm your intent

Technique-Specific Requirements

Each printing method has its own artwork rules. Find yours below.

Screen Printing

  • Supply artwork as spot colours only — no gradients or colour blends
  • Each colour = one separate screen; keep colour count to 1–6 for best economy
  • Include Pantone (PMS) references for each colour
  • Ensure all elements have 100% opacity — no transparency or drop shadows
  • Minimum line thickness: 0.5pt for solid, 1pt for halftones
  • Provide print-ready vector file (AI or EPS) at actual print size
  • Overlapping colours: indicate overprint or knockout on your file

DTF Printing

  • Full CMYK colour range supported — gradients, photos and complex artwork welcome
  • Supply PNG with transparent background for best results (no white box around design)
  • Minimum resolution: 300dpi at final print size
  • CMYK colour mode preferred; sRGB accepted
  • Avoid very fine detail under 1mm — may not reproduce precisely at small sizes
  • White elements will print as white — ensure any white in design is intentional

Embroidery

  • Provide a clean vector file (AI, EPS, SVG) or high-res PNG at 600dpi+
  • Keep designs bold and simple — fine lines, thin serifs and small text don't stitch well
  • Maximum colours: 15 thread colours per design
  • No gradients — thread cannot blend smoothly; use solid colour blocks
  • Minimum text size: 4mm cap height (~11pt at print scale)
  • Include Pantone references for each colour for thread matching
  • We will send a digitised stitch preview for approval before production

Vinyl Transfer

  • Supply clean vector file (AI, EPS, SVG) for cut vinyl — no raster or gradient fills
  • For printed HTV (full colour): PNG at 300dpi+ with transparent background
  • All elements must be closed paths — no open outlines or stray points
  • Minimum line/element width: 2mm — thinner elements won't cut or weed cleanly
  • Avoid very fine detail — intricate elements can tear during weeding
  • Specify vinyl colour(s) from our range, or Pantone reference for closest match

Questions & Answers

Artwork FAQ

Possibly, yes. If the JPEG is high resolution (300dpi or more at the intended print size) and the design is clean with no text that needs to be re-scaled, we can often work with it. Send it over and we'll let you know straight away. For the best quality result, a vector file is always preferred.

Yes — we offer a logo redraw service from £25, where our team manually redraws your artwork as a clean vector file. This is a one-time cost and the resulting file is yours to keep. Contact us to discuss.

Always. We'll send you a digital proof (PDF or PNG mockup) showing your design on the garment before we begin production. We won't print anything without your written approval.

Screen colours (RGB) are always slightly different from printed colours (CMYK). This is normal and unavoidable. For critical brand colour matching, provide us with Pantone (PMS) references and we'll match as closely as possible. For screen printing, we can produce a physical strike-off proof (additional cost) before the full run.

You must have the rights to use any design we print. We cannot produce items that infringe on third-party copyrights or trademarks. This includes unlicensed use of band logos, sports team badges, brand logos, or copyrighted images. We reserve the right to decline any order where rights cannot be confirmed.
