Understanding the Importance of Vector Files in T-Shirt Printing

[Eliza_M]

I’ve been working on a few T-shirt printing projects lately and noticed how much of a difference vector graphics make compared to raster images. Vectors keep designs crisp, clean, and scalable; especially important when printing larger graphics or logos. I’m curious to hear how others here manage their artwork conversion process. Do you prefer creating designs directly in Illustrator or converting them from other formats? Also, what’s your go-to method for maintaining color accuracy between digital designs and printed results? Looking forward to learning from your experiences and workflow tips when it comes to creating the perfect vector file for t-shirt printing.

These are great questions and I'm curious on how others do it too, and / or tips and tricks that anyone wants to share regarding screen printing requirements. I do graphic design mostly for creating signage and sometimes heat press designs on t-shirts and other fabric using VE Master Plus software. So the design work is for a vinyl cutter, so it needs to be vectorized and broken out per color.
When doing t-shirt designs (to be printed by a screen printing company, not me) I do the same thing assuming they need to control the color "layers", but I don't know for sure what they actually do with my work. I export the design in vectorized .eps and .AI files for them to work with. I don't know exactly how they "use" them, maybe I'm doing too much? I don't get too much into color control, but would like to know how others handle that too.

Sounds like you’re already doing things right. Screen printers typically separate colors themselves, so providing clean vector EPS/AI files is perfect. You’re not overdoing it—just ensure spot colors are labeled clearly for smoother production.

As long as you have high quality artwork, raster isn't that bad to work with. You just need to set up your channels correctly and understand separations. I worked in offset printing for years and dealt with separations for platemaking from both raster/vector artwork. It's all of the special effects and transparencies (like drop shadows and glows) that can drive you nuts getting to separate correctly.

jfiscus is right, with the added "drive you nuts" of the client who thinks you can use the logo file on their website, in .png, to create anything larger than a 3" x 2" print, sign, etc. "But it looks fine on my phone!"
