How to Prepare Your Artwork for Custom Apparel Printing: A Comprehensive Guide

When it comes to custom apparel printing, the quality of your final product hinges on how well your artwork is prepared. Whether you’re designing t-shirts for a team event, promotional gear for your business, or personalised gifts, understanding how to prepare your artwork correctly is crucial. In this guide, we’ll walk you through the essential steps to ensure your designs turn out looking sharp and professional.


1. Choose the Right File Format

The format of your artwork can significantly affect the quality of your print. Here are the most commonly accepted file formats:


Vector Files (Preferred): Formats like .AI (Adobe Illustrator), .EPS, and .PDF are ideal because they can be resized without losing quality. Vector files use mathematical equations to create clean, crisp lines and shapes, which is perfect for printing.


Raster Files: Formats like .JPEG, .PNG, and .TIFF can be used, but they are resolution-dependent. Raster files are made of pixels, so enlarging them may result in a blurry or pixelated image. If you use raster files, ensure they are high resolution (at least 300 DPI).


2. Set the Correct Resolution

For raster images, resolution is key to ensuring clarity and detail in the final print. Follow these guidelines:


High Resolution: Use a resolution of at least 300 DPI (dots per inch). This ensures your image is sharp and detailed. Lower resolutions can result in pixelation and a less professional finish.


Dimensions: Design your artwork at the actual size you want it to appear on the apparel. If you need to scale it up or down, make sure you do so proportionally to avoid distortion.


3. Use the Right Colour Mode

Colour mode affects how colours appear in print. The two primary colour modes are:


CMYK: Stands for Cyan, Magenta, Yellow, and Key (Black). This colour mode is used for printing and will give you a more accurate representation of how colours will look on the final product.


RGB: Stands for Red, Green, Blue. This mode is used for digital screens and may not accurately translate to print colours. If your artwork is in RGB, convert it to CMYK before sending it for printing.


4. Prepare Artwork with the Right Dimensions

Ensure that your artwork is set to the correct dimensions for your apparel. Here’s how to get it right:


Size and Placement: Measure the print area on your apparel and create your artwork to fit within these dimensions. Common print areas are 12”x16” for t-shirts, but this can vary.


Bleed Area: Include a bleed area (usually around 0.25 inches) around your design if it extends to the edges. This prevents white borders from appearing if there is any slight misalignment during printing.


5. Convert Text to Outlines

If your artwork includes text, convert it to outlines to avoid font issues:


Text to Outlines: In vector software like Adobe Illustrator, convert text to outlines (also called converting text to paths). This ensures that your text will appear as intended, even if the printer doesn’t have the same fonts installed.


6. Ensure Proper Alignment and Spacing

Double-check your design for alignment and spacing issues:


Alignment: Make sure all elements are properly aligned. Misalignment can cause parts of your design to be cut off or misprinted.


Spacing: Ensure there is enough space between design elements and the edges of the print area. This avoids any important parts of your design being too close to the edge.


7. Proof Your Artwork

Before finalising your artwork, create a proof to review:


Proofing: Print a sample of your design on paper to check colours, placement, and overall appearance. This helps you catch any issues before committing to a full print run.


Review: Have someone else review the proof as well. A fresh set of eyes can spot errors you might have missed.


8. Save and Send Your Files Correctly

Finally, save and send your files in a way that’s easy for the printer to work with:


File Naming: Use clear and descriptive file names. Include the type of product and the design version (e.g., “Team_Shirt_Design_v1.eps”).


File Transfer: Send your files through a reliable method, such as a file-sharing service or email. Ensure that the files are not compressed or altered in transit.



Preparing your artwork for custom apparel printing is a crucial step in ensuring a high-quality final product. By following these guidelines—choosing the right file format, setting proper resolution, using the correct colour mode, and more—you’ll set yourself up for printing success. With well-prepared artwork, you can be confident that your custom apparel will look as fantastic as you envisioned.
