The fastest way to slow down a custom uniform order is a bad artwork file. Not the fabric, not the printing method — the file. A blurry logo, a low-resolution photo, or a font that doesn't transfer correctly can add days of back-and-forth before production even starts.
This guide explains exactly what a custom sportswear factory needs from your design files, in plain language — no graphic design degree required. It is written for team managers, club buyers, school athletic directors and dealers who order jerseys in bulk, not for professional designers.
Why Your Artwork Files Matter More Than You Think
Most custom team jerseys today are made with dye-sublimation printing, where the design is printed onto transfer paper and then bonded into the fabric itself. Because sublimation prints from a digital file, the quality of your finished jersey can only be as good as the file you send. If the file is low-resolution, the printed crest will look soft and pixelated — and no factory can fix that at the printing stage.
Your artwork also directly affects your timeline. Incomplete files mean extra rounds of questions and corrections. Complete files mean your order moves straight from inquiry to digital proof to sampling. At ZHONGKANG, we reply to every inquiry within 24 hours and hold free digital proofs up to 5 rounds of revisions — but the faster your files are ready, the faster the whole order moves.
Vector vs. Raster: The File Format Question
Every image file is either vector or raster, and the difference decides whether your logo prints crisp or blurry at jersey size.
- Vector files (AI, EPS, PDF, SVG) are built from mathematical curves. They stay razor-sharp at any size — ideal for logos, crests and text.
- Raster files (PNG, JPG) are grids of pixels. They look fine at screen size but become visibly soft when enlarged onto a chest-sized crest.
What to send: If you have a vector file of your logo or crest — send that first. Common logo formats from design software or brand guidelines (AI, EPS, PDF, SVG) are exactly what a sublimation factory works with best. If you only have PNG or JPG, it can still work: the file should be large and sharp, ideally 300 DPI at the size it will actually be printed. A good rule of thumb — if the logo looks soft when you zoom in on your screen, it will look soft on the jersey.
Logo & Crest Files: 5 Rules That Save You a Round of Fixes
- Never take logos from websites. Downloading a crest from a club site often gives you a small, compressed image that will print poorly. Ask your league, school or brand for the original logo file instead.
- Prefer a transparent background. A transparent PNG or a vector file lets us place the logo cleanly over any jersey color. A white box around the crest is the most common artwork mistake we see.
- Send the largest version you have. Even if it looks oversized on screen, a large original can always be scaled down — a small file cannot be scaled up.
- Don't crop, compress or "enhance" the file yourself. Send the untouched original. Every export through a chat app or social media compresses the image.
- Send front and back views separately. If your design has different elements on the jersey front, back and sleeves, send them as separate elements rather than one flat composite — this makes placement far easier to get right.
Getting Colors Right
Screen colors never match printed colors exactly, so don't rely on what you see on your monitor.
- Send color codes when you have them. If your school or brand has official Pantone (PMS) numbers, include them in your email — a color code is simply a common way to describe a color precisely. Final colors are confirmed on the digital proof and the approved sample.
- Send a reference image of the look you want (an old jersey, a mockup, a photo of the team in action) alongside the files. Visual references resolve more questions than any written description.
- Understand the fabric factor. Sublimation prints into the fabric itself, and colors can look slightly different on white versus colored base fabric. Your factory will confirm the closest match during the free digital proof — which is exactly why that proof step exists before you pay for anything.
Names, Numbers & Fonts
Player names and numbers are the part of the order where file problems show up fastest.
- Tell us the font you want, or send a sample. Don't assume the factory has your school's athletic font in its library.
- Check font licensing before you send. Some popular display fonts are licensed for personal use only. For commercial team orders, stick to fonts that allow commercial use, or ask your factory to recommend a safe alternative.
- Send the roster in a simple list — name spelling, number, size for each player. A spreadsheet or a plain text list beats a screenshot every time.
- Mention special requirements clearly: goalkeeper jersey contrast, captain's armband marks, patch positions — note them in the same email as the files, not in a later message.
The Complete Checklist: What to Send in One Email
If you are ready to order, this is everything a custom uniform factory needs from you the first time:
- Sport and garment type (jersey only, or jersey + shorts + socks)
- Quantity and size breakdown (we can produce adult and youth sizes — send us your roster)
- Logo and crest files (vector preferred, transparent background)
- Color codes if you have them (Pantone or brand colors)
- Font preference for names and numbers
- Any special requirements: sleeves, patches, reversible panels, custom trim
That is it. You do not need a finished design — you need the ingredients. From these, the factory builds the digital mockup for your approval.
No Design Files? You Still Have Options
Many team buyers assume that without a graphic designer on staff, they cannot order custom uniforms. That is not true.
If you have a sketch on paper, a photo of an old jersey, or even just a clear description of the colors and layout you want, tell your factory. At ZHONGKANG, our team helps you develop the design from your sketch or photos until you are happy with it — the digital proof is free, and you get up to 5 rounds of revisions before anything goes to production. You can also combine approaches: use our design help for the layout, then approve the mockup and move to a physical sample (usually about 7 days to make) before committing to the full order.
FAQ
What file format is best for custom jersey printing?
Vector formats (AI, EPS, PDF, SVG) are best because they stay sharp at any size. If you only have PNG or JPG, send the largest, highest-resolution version you have — ideally 300 DPI at print size.
Can I send a logo downloaded from a website?
It will usually be too small and compressed for clean printing. Ask your league, school or brand for the original logo file — that is the version that will print correctly.
Do I need design software to order custom jerseys?
No. Send us a sketch, photos or a description and we will develop the design with you. Digital proofs are free with up to 5 rounds of revisions, so you can refine everything before production starts.
What is the MOQ if I only have a simple design?
MOQ starts at 10 pieces per design, so small clubs and trial orders are welcome. See our guide to MOQ and pricing for the full breakdown.
How do I check colors before the bulk order?
The free digital proof shows the design on your jersey colors for approval. If you want to verify fabric and print quality in person, order a physical sample (US$15–50 per style, about 7 days to make) before the bulk run.
