In Photoshop select Image, Image Size from the menu to see what DPI your image has, and/or to change its DPI
Probably the most confusing aspect of getting your artwork printed onto fabric and paper is the issue of DPI, or Dots Per Inch, which can have a big effect on your print outcome.
Your image has a particular dpi, but when you get it printed, that image, no matter what it's actual dpi, can be printed at any dpi. This effectively scales the image to different sizes; it can also affect print quality, too. The more dots per inch there are in your image, and the more dots per inch there are for your print, the higher quality the outcome will be.
Often, the problem people encounter is envisaging how big or small their image will look when it is printed at a particular dpi.
Our print preview is designed to help you see what effect different settings for the dpi of your print will have on the scale, and printed outcome of your image.
If you can not see the preview, or if you are having trouble working out what print dpi to select, please contact us, we will be happy to email you your print preview or offer advice.
Something else to be aware of: sometimes resolution is expressed as dots per centimetre rather than dots per inch. We don't use dpc, but sometimes we receive images from you where the resolution is set as dots per centimetre.
