Yikes--I am alarmed to read all these suggestions to heat set the label after printing. I just finished a quilt with a home-printed photographic label using Printed Treasures fabric and instructions which did not mention heat-setting the ink. Instructions indicated I should let the ink dry completely, then use a dry iron on a low (silk or wool) setting to press the paper side of the label. I understood this step was to help with removing the paper backing for which users have criticized the product in online reviews. The final step in the instructions was to rinse in cool water until clear in order to "carry off" any excess dye. FWIW I used a Canon (MX922) inkjet with fresh new inkjet cartridges ($84 worth at Costco) to print the label, but except for the dry iron pressing of the paper backing, no heat to speak of.
Should I go back to iron it with a hot iron? Could it hurt? TIA and happy mother's day to all the mothers on this list.
