Print white as an overprint in one pass for reverse printing (typically used for transfer printing of textile and hard
surfaces), where white is needed as an overprint, applied on top of all the other colors. When the image is pressed to
the garment, the transfer sheet is flipped over and the white becomes the underprint. This is especially important
where images have half tones and 100% transfer of the image can be problematic, or when there is white in the
image that needs to show through on dark colored garments.
White toner performs the following functions:
1) To produce the color white on a dark garment.
2) To fill in the halftones on lighter images so that there is enough toner on the page to fully transfer to your
garment or to pull all the B adhesive.
This second point is the most important one and the reason why you cannot simply use a CMYK printer for
transfer printing. Also, this is why you MUST use the color white all the time (assuming your image has some
halftones in it). Even when printing on a white garment and there is no white at all in your artwork. This is the
biggest misconception with new users.
Don't make that mistake, always use the white toner cartridge for any type of transfer printing!
