Branding & Customisation
Getting your logo onto a branded product sounds straightforward — until your supplier comes back with a list of technical requests you weren’t expecting. Artwork file requirements for promotional product printing are one of the most commonly misunderstood aspects of the branded merchandise process, and getting them wrong can delay your order, inflate your costs, or result in a finished product that doesn’t look the way you envisioned. Whether you’re a Melbourne marketing manager ordering 500 branded tote bags for a conference, or a Sydney-based HR coordinator putting together a corporate welcome kit, understanding what your print supplier actually needs before you submit your artwork will save you significant time, money, and frustration.
Why Artwork Quality Matters More Than You Think
Many organisations assume that a logo downloaded from their website, or a high-resolution JPEG saved from a presentation, will be sufficient for product decoration. Unfortunately, that’s rarely the case. Promotional product printing involves a range of decoration methods — screen printing, embroidery, laser engraving, sublimation, pad printing, and more — each of which has its own specific artwork demands.
A supplier working to a tight turnaround can’t always spend hours recreating or repairing your artwork. If your files aren’t print-ready when they arrive, you’ll likely face a redraw fee (typically ranging from $50 to $150 or more), additional delays in proof approval, and sometimes a compromised result if workarounds are needed. For time-sensitive orders — like merchandise for a trade show or a welcome event — these delays can be particularly costly.
Understanding the fundamentals of artwork file requirements early in your planning process is one of the best investments you can make in your branded merchandise project.
Vector vs Raster: The Most Important Distinction
The single most important concept to grasp when preparing artwork for promotional product printing is the difference between vector and raster files.
Vector Files
Vector files are built from mathematical paths and anchor points rather than pixels. This means they can be scaled to any size — from a 10mm pen imprint to a 3-metre banner — without any loss of quality. The lines stay crisp, the colours remain accurate, and the file remains fully editable.
Common vector file formats include:
- .AI (Adobe Illustrator) — the industry standard; most preferred by suppliers
- .EPS (Encapsulated PostScript) — widely accepted and compatible with most design software
- .PDF (when created in a vector-based application like Illustrator or CorelDRAW)
- .CDR (CorelDRAW) — used by some suppliers, though less universal than AI or EPS
If your organisation has had a logo professionally designed, your designer should have supplied you with vector files in one of these formats. If you can’t locate them, it’s worth contacting your original designer before you place a merchandise order.
Raster Files
Raster files are made up of pixels arranged in a grid. Common formats include JPEG, PNG, GIF, and TIFF. While raster files are fine for digital use, they have fixed resolutions. When scaled up, they become blurry and pixelated — which produces poor print results.
A common mistake is supplying a logo pulled from a website (typically 72 DPI) and expecting it to print cleanly on a polo shirt or promotional water bottle. Website images are optimised for screens, not print. Even if the file looks sharp on your monitor, it may print as a blurry mess at production size.
When raster files are the only option (for example, a photograph used in full-colour sublimation printing), the minimum acceptable resolution is generally 300 DPI at the actual print size. A file that’s 300 DPI at 5cm wide but needs to be printed at 20cm wide won’t meet the required resolution once scaled.
Colour Modes and PMS Matching
Colour accuracy is another critical element of artwork file requirements for promotional product printing, particularly for organisations with strict brand guidelines.
CMYK vs RGB
Most promotional product printing is done in CMYK (Cyan, Magenta, Yellow, Key/Black) colour mode — a subtractive colour model used in physical printing. RGB (Red, Green, Blue) is the colour model used by screens and digital displays.
When an RGB file is converted to CMYK for printing, colours can shift noticeably. Vibrant blues may become duller, and certain neon or fluorescent tones are simply outside the CMYK gamut. Always supply your artwork in CMYK colour mode if possible, and check that your brand colours look accurate in CMYK before submitting.
PMS Colour Matching
For organisations that need precise, consistent colour reproduction — particularly for screen printing on custom t-shirts, embroidered custom caps, or pad printing on pens — Pantone Matching System (PMS) colours are the gold standard. PMS colours are standardised ink references that ensure the specific shade of your corporate blue or red is replicated consistently across different products and different suppliers.
When you brief a supplier, include your PMS colour references if you have them. This is particularly important when ordering products across multiple categories — for example, combining branded tote bags with custom apparel and promotional USB drives for a corporate event kit. Consistent PMS usage ties everything together visually.
If your brand guidelines don’t include PMS references, your graphic designer or print supplier can usually assist with finding the closest match.
File Setup for Specific Decoration Methods
Different decoration methods impose different artwork requirements. Here’s a practical overview of the most common techniques:
Screen Printing
Screen printing works best with solid, flat colours. Each colour in your design requires a separate screen (and often a separate setup fee). Artwork should be supplied as a vector file with clearly separated spot colours. Gradients, fine details, and photographic images are difficult to reproduce accurately through screen printing.
If you’re ordering custom t-shirts in bulk, a two or three-colour logo will generally produce cleaner results and lower costs than a full-colour photographic design.
Embroidery
Embroidery requires your artwork to be converted into a digitised stitch file (.DST, .EMB, or similar formats). This process — called digitising — is typically done by the supplier, but your artwork still needs to be a clean, high-resolution vector or raster file at sufficient size. Very fine lines, small text (under 4–5mm), and complex gradients don’t translate well to embroidery stitches.
For workwear, polos, and corporate jackets, embroidery delivers a premium, long-lasting result — but the artwork needs to be simplified in some cases to suit the medium.
Sublimation Printing
Sublimation allows for full-colour, edge-to-edge photographic printing and is ideal for products like sublimation printed shirts, ceramic mugs, and certain drinkware. This method requires high-resolution raster files (minimum 300 DPI at print size), typically in RGB colour mode since sublimation inks are often calibrated to RGB profiles. Always confirm colour mode requirements with your specific supplier.
Laser Engraving and Pad Printing
Laser engraving works best with high-contrast, single-colour artwork — vector files are strongly preferred. Fine detail can be reproduced well, but gradients and multi-colour designs aren’t suitable. For tech promotional gadgets like power banks, chargers such as the Pulse Apollo Charger, and metal drinkware, laser engraving delivers a sophisticated, permanent result.
Pad printing, often used for small promotional items like pens and lanyards, requires spot-colour vector artwork. Each colour is printed separately, so minimising the colour count keeps costs manageable.
Practical Artwork Preparation Checklist
Before submitting artwork to your supplier, work through the following checklist:
- File format: Supply AI, EPS, or vector PDF as a first preference
- Colour mode: CMYK for most printing; confirm with supplier for sublimation
- Resolution: Minimum 300 DPI at actual print size for raster files
- Fonts: Convert all text to outlines (curves) to prevent font substitution issues
- PMS colours: Include PMS references where brand colour accuracy is critical
- Bleed and safe zone: For full-bleed products (e.g., sublimated shirts, banners), include 3–5mm bleed beyond the trim line
- Layers: Keep design elements on separate, clearly labelled layers for ease of editing
- Background: Remove any white or coloured background if the product colour should show through
- Size: Supply artwork at 1:1 scale or clearly indicate the intended print dimensions
Working With Suppliers on Artwork Approvals
Most reputable suppliers will send you a digital proof before production begins. This is your opportunity to review the placement, size, colour, and overall appearance of your branded design on the product. Take this step seriously — once production commences, changes are typically not possible.
Respond to proof approvals promptly, particularly if you have a deadline. A delayed sign-off can push your delivery date back, which matters when you’re producing summer branded gifts for clients ahead of the festive season, or sourcing eco-friendly promotional products for a time-sensitive sustainability campaign.
If you’re ever unsure about artwork requirements, ask your supplier upfront. A brief conversation before you finalise your files can save a considerable amount of back-and-forth later. Many suppliers also offer artwork redraw or setup services for a fee — a worthwhile investment if your only available file is a low-resolution logo from your website.
Budgeting for Artwork-Related Costs
Artwork costs are often overlooked when budgeting for branded merchandise. Here’s what to factor in:
- Setup fees: Most decoration methods involve a one-off setup fee per design element, ranging from approximately $30 to $100 per colour or position
- Digitising fees: Embroidery digitising typically costs $50 to $150 depending on stitch count complexity
- Redraw fees: If your artwork isn’t print-ready, expect to pay $50–$150 or more for a professional vector redraw
- Sample fees: Ordering a physical pre-production sample adds cost but is strongly recommended for large or complex orders
Understanding these costs upfront helps you present an accurate budget to stakeholders — whether you’re a Brisbane school organising end-of-year merchandise, a Canberra government department sourcing corporate gifts, or a Perth-based events team planning for an upcoming expo.
Conclusion: Key Takeaways
Artwork file requirements for promotional product printing don’t need to be overwhelming once you understand the fundamentals. Getting your files right from the start dramatically improves your results, reduces delays, and ensures your brand looks as good on a product as it does on your website or letterhead.
Here are the key points to remember:
- Always supply vector artwork (AI, EPS, or vector PDF) as your default format — it scales infinitely without quality loss and is the accepted standard across all major decoration methods
- Resolution matters for raster files — 300 DPI at the actual print size is the minimum; anything less risks blurry, unprofessional results
- Colour accuracy requires attention — use CMYK colour mode for most print methods and include PMS references where brand consistency is non-negotiable
- Different decoration methods have different requirements — screen printing, embroidery, sublimation, and laser engraving each demand specific file setups, so confirm with your supplier before preparing artwork
- Budget for artwork-related costs — setup fees, digitising, and potential redraws are a normal part of the ordering process; factoring them in from the outset avoids unwelcome surprises
Whether you’re exploring unique corporate gifting ideas or sourcing promotional products for your next event, getting your artwork right is the foundation of a successful branded merchandise project.
