Preparing A Photograph To Print Using White Ink Only On Black T-Shirts

This video covers using Adobe Photoshop to convert a photographic image to a 1 color image printable using white ink on a black or dark t-shirt. Although we usually recommend a grayscale separation using multiple grays, white and black to simulate a photo, sometime printers need to use white only. The video discusses adjusting an inverted grayscale image and how to make accurate adjustments within the channels panel of Photoshop.

To correct a mistake within the video....the keyboard shortcut on Macintosh to fill a layer or channel with the foreground color or density is Option-Delete and not Command-Delete. Also, for this to work, the foreground color in Photoshop's toolbar needs to be set to black.
You could also go to Edit > Fill from the menu bar and choose to fill with 100% Black.
