When it comes to screen printing, the quality of your artwork file makes all the difference. While you may be tempted to send a quick JPEG or screenshot, the truth is that vector art works the best for screen printing.

From ensuring clean color separations to maintaining crisp detail at any size, vector files are the industry standard for professional results. Let’s break down why.

What is Vector Art?

Vector art is created using software like Adobe Illustrator or CorelDRAW. Unlike pixel-based images (raster graphics like JPEGs or PNGs), vector art is made from mathematical lines and shapes.

This means you can scale a design from the size of a business card to a billboard without losing any detail or sharpness.

The Problem with Low Resolution Images

Many first-time customers send screen printers files that look fine on a phone but aren’t suitable for production. Here’s why:

If the art file is low resolution, it’s difficult to separate colors and get it ready for printing.
Raster images are measured in DPI (dots per inch). For print, 300 DPI is considered “high resolution.”
Anything lower can look blurry, pixelated, or jagged once enlarged for t-shirt printing.

In other words, a file that looks okay online may not translate well to a print shop.

Why Vector Art is Needed for Screen Printing

Here’s why vector art is the gold standard:

Clean Color Separations

Screen printing requires each color to be isolated and printed on its own screen. Vector art is needed to separate colors accurately, ensuring sharp edges and no fuzzy overlaps.

Infinite Scalability

Need the design on a chest print and a full back print? No problem. Vector art scales perfectly without losing resolution.

Crisp Lines and Shapes

Text, logos, and fine details all stay sharp. With raster images, these can blur or distort.

Faster Setup in Production

Printers can prepare screens more efficiently when the artwork is already in vector format. This saves time and reduces the risk of errors.

Vector Art vs Raster Images (JPEG/PNG)

Feature	Vector Art	Raster Image
Resolution	Infinite scalability	Limited by DPI (needs 300 dpi for print)
File Types	AI, EPS, SVG, PDF	JPG, PNG, GIF
Best For	Screen printing, logos, text	Photos, web images
Color Separation	Easy & precise	Difficult & blurry

When to Use Raster Images

Raster files aren’t always bad. Photographs or detailed full-color images are raster by nature. But for screen printing, they require high-resolution (300 DPI) files and sometimes extra work to prepare for color separation.

That’s why for most logos, text, and graphics, vector art is the most reliable option.
