Screen printing on unwashed canvas
  • Hi, do I have to pre-wash the canvas bag before I print on it? Will it affect the washability? I'm doing this as a make it take it project, so if I don't have to pre-wash, that would make it easier.

    If I were to screen print on towels, would I have to pre-wash them? Both are 100% cotton. Thanks for your help, sue
  • Hi there,

    It is a good idea to pre-wash most anything before you print (or dye). There are any number of types of sizings that are used these days and they may interfere with the fixing process.
