I have an HP inkjet printer. I found a recipe of the internet for a solution to use to set the printer ink for permanency when printing onto fabric. Here's the ingredients:
30 parts hot water, 10 parts alum, 4 parts washing soda, 1 part fabric softner. Soak the printed fabric. I found the grams translated on the internet as well. Click on the photo to see the recipe card bigger.
I had a page of postcards printed. You iron your plain fabric onto the waxy side of freezer paper and then cut it to 8.5 by 11 inches to fit your printer. I cut my print in half to keep one original. Here's how the colors compare after soaking.
ALL the blue drained out and turned the solution blue. ; ( Look at the little window in the prints. See how it's lost the color? Ick.
Back to the drawing board. If anyone else knows the trick, please email me!!
