These are the canvas types i most often see advertised: 100% cotton, 65/35 polyester-cotton, and all polyester. Briefly if you can, which one are you most often using, and what are the major disadvantages/advantages of the other types.
A friend of mine recently bought an inexpensive 16"x40' roll of all cotton canvas. He later told me that the canvas had shrunk 1/2" after printing and coating, which was going to make life difficult finding custom stretcher bars. When i measured it later, it actually shrunk 3/8" in 16", which equates to 2.3%. Are some manufacturers of all cotton canvas preshrinking them, or is shrinkage always a problem with cotton canvas?
All that i've used in my printer is a poly/cotten blend so haven't experienced print shrinkage before. So thats the background of my question. Also, which blend is better for printing quality? Thank you for any information you can share on this topic!
