Please help us expedite your job by taking a few minutes to check the items in this list before submission. We understand that circumstances do not always permit strict adherence to these guidelines, but we hope that this clarification will at the very least open the lines of communication. If you have any questions please contact us via email at info@rcsilk.com or call 617.241.9880



What types of files do you accept?

Since silkscreening is a positive/negative process, involving blocks of color, we work with Vector formats of eps or PDF files only. A vector image is defined by lines, curves, and fills, as opposed to a photographic, bitmap or halftone image, such as a digital photo, which is defined by small pixels of color (see the image below). RC Silk uses only Adobe® Illustrator, so if you are saving from another program and you have the option to save as an Illustrator eps, please do choose that option.

We can print color photographic images, but the process is a bit different and will affect your cost, so please consult your rep for details.

How should I set up my files?

In general, keep in mind that most screen printing is a spot color medium, as opposed to offset, where the majority of color work is process.

  • If identical objects overlay one another precisely, please separate by layer.

  • If appropriate, submit files with all colors converted to spot, and all unused colors deleted from the document.

  • Unless there is a large body of text in the file, please convert all type to outlines. As most t-shirt designs are not text intensive, this will prevent confusion and save you the time of loading fonts onto the disk.

  • The background of "white" in your design program is not a printable color! it's just the background. Therefore, if you need to print white, you will need to spec it out as a separate ink, the same as you would black, red, yellow, etc. White may also need to be added to an image as either an underlay on darks, a highlight after print, or both.

  • Use PMS numbers for color names. Even though the generic "Red" that your software or design specifies might look perfect on your monitor, all monitors display differently, so using a standard method to designate colors, like the Pantone Matching System, is essential. Be sure to check the PMS book for color accuracy as the on-screen versions are often misleading.

How do I get my files to you?

Simple files can be sent via email to art@rcsilk.com. If you have a large format file, you can contact us to upload to our FTP site, or send us a CD/DVD to our office.

What colors can I use?

RC Silk uses the Pantone Matching System (PMS#) to insure consistency for all orders. That means your tenth reorder will look exactly as your first order.  Provide us with your color selections and we will match printed ink, and stitched thread to your selection.
