That sounds like my husbands problem Ready to Press DTF Transfer (Fabrics only)

The word husband is transparent.. making it the color of whatever you apply it to 

DTF (Direct-to-Film) printing involves transferring a design onto a garment using a heat press. To achieve a successful DTF print, you'll need to prepare the garment, position the transfer, apply heat and pressure, and then peel away the film. Most DTF transfers require a medium to high pressure and a temperature around 300-325°F (149-163°C) for 10-15 seconds

please note:

Mock up color can slightly differ From Actual Print...
