Art File Requirements
The file type and quality of your uploaded design directly impacts the quality of your screenprinted shirts, and the speed in which we can create and send your proofs for pre-production review. As a general rule of thumb, please provide the best files you have.
Accepted File Formats
We allow the following file types when uploading your designs on our website:
.ai / .psd / .eps / .pdf / .png / .jpeg / .svg
The maximum file size per upload is 10MB. However, if your file is too large to upload, you can also email it to help@ultrapress.com after you place your order.
Ideal File Type - Vector
For the best quality when it comes to screenprinting, vector files are highly recommended. Vector files are made with precise lines, paths and anchors. Vectors can be enlarged without losing quality, and there are no issues when it comes to pixelation/blurry outputs. Therefore, when screenprinting your art, especially at larger dimensions such as the back of a t-shirt, the result is a much cleaner and crisper print.
Most common vector file extensions end in .ai, .eps, .pdf.
Note - if providing vector files, please outline text/fonts and flatten layers.
Next Best File Type - Raster (150 dpi or above)
If you don’t have access to vector files, then providing raster files with a minimum resolution of 150 dpi at the size you want your design to be printed is the next best alternative to vector files. Dots per inch (dpi) refers to the image’s resolution. For example, if you send an artwork that’s sized at 5 inches x 5 inches and is 150 dpi but you want to enlarge it to print at 10 inches x 10 inches, the resolution will now become 75 dpi.
Most common raster file extensions end in .jpeg, .png, .psd.
Please note: if you paid for an Expedited Proof and you do not have at least the next best file type explained above, your proof may exceed the advertised turnaround time.
Bare Minimum Art File Requirements
If you don’t have access to either vector or 150 dpi raster files listed above, then at the minimum we will need your file in a digital, graphical format. Upload or send us whatever the highest resolution files you have.
Please note that in these cases, the following may occur:
Longer proofing turnaround (past 48-72 business hour standard)
Reduced print quality if your submitted file is too low resolution
As long as you can provide this bare minimum digital file of your design, we will still create free proofs for your review. Please see the Free Proofing Services article for more info.
Please note we do not provide artwork or design creation services and we DO NOT accept the following:
Incomplete designs using files that are meant to serve as inspirations and references
Hand drawn sketches
Photographs of previous t-shirts
