Artwork requirements depend a lot upon what is being printed.
For t-shirts and many promotional items, "line art" is required, which means clean black and white, from the days before computers.
Ideally, your computerized logo/design will be provided in a vector format (with color okay)
A vector format allows the image to scale without losing any resolution, and makes separating the colors easy, if there is more than one color being printed.
Vector file formats are created in a graphic program like Affinity Designer or Adobe Illustrator.
Common filetypes are:
.eps Encapsulated Postscript
.svg Scalable Vector Graphics
.ai Adobe Illustrator
.afdesign Affinity Design
.pdf Portable Document Format (best for 1-color image)
.jpg and .png are to be avoided, but are useful to include as a proof in case the file doesn't load properly. We will regularly send you back a proof in these formats to check that the artwork is correct.
Digital printing is the exact opposite of "line art." Now we want .jpg and .png images in full color at high resolution. .pdf is excellent and common, too.
In the real world, most people don't have a graphics program, and no desire to buy one or learn how to use it. No Problem!
We can handle whatever you need. We have lots of fonts, and probably a million pieces of clip art. We can create a design, a layout, a logo. We can work from whatever you have and make it press-ready. Most times there is no charge, but when we do charge it is always reasonable.
