Files under 300dpi are generally not acceptable for print work. Taking a lower resolution file and increasing its resolution to 300dpi (upsampling) will often result in a blurry image that is also unacceptable for print work. As technology gets better the algorithms used for upsampling have gotten much better and often the result is adequate for screen printing, but not always, send what you have and we’ll let you know if it will work.

If creating a raster format image (.PSD, .TIFF, some .PDF files) your artwork should be created at the finished print size (if you want the print on the shirt to be 12" wide, the art needs to be created at 12" wide) at 300dpi from the start to guarantee a good result.  

.JPG files are generally not the best choice for print work as artifacts are often introduced to the image and details are lost in the compression process every time the file is saved.  We can often use .JPG images with no issues, but it is not the best choice and may incur fees to fix the image if artifacting is severe.

Microsoft Word, PowerPoint, and Publisher files are absolutely not acceptable file formats for screen printing.  If you provide files in these formats artwork charges will definitely apply because we will have to recreate your artwork from scratch.
