What file type should my artwork file be?
Preparing artwork for T-shirt printing can be tricky, especially if you’re not a designer. One common issue is submitting artwork in the wrong format, which can delay orders. The best file type depends largely on your order size and the printing method. Use this updated guide to understand what’s required for both small and large orders.

Preparing artwork for T-shirt printing – complete guidelines based on your order size
The type of artwork required for the most part depends on your order size, as this dictates the process that will be used.
File resolution: what is the best DPI for T-shirt printing?
The minimum resolution recommended for printing is 150 dpi, the optimum being 300dpi. The higher the resolution, the more detail is held within the graphic.

The artwork should be submitted at the actual print size. This is important as the resolution may be correct but if the image size is small, when it is blown up to actual size it will still be pixelated.
Common design file types explained

PSD simply stands for ‘Photoshop Document’ and is a raster file. In simple terms, this means that the image is made up of pixels with information stored in each one relating to colour and location. If your file has layers, it is best to flatten the image before sending the artwork as the file sizes can be too large to send across.

An AI file is an Adobe Illustrator vector file. A vector image is made up of mathematical points that define the shape of the image rather than being made up of pixels. Arguably, this is the best file format as it can be scaled to any size without becoming pixelated.

PNG stands for Portable Network Graphic. It is a popular file format designed to replace the well-known GIF format and for displaying images on the web. The main benefit of this file is that it is capable of supporting a transparent background and 16.4 million colours.
