OK, by request and certainly not because I am any kind of expert at this, I am showing how I transfer an image onto canvas.
Here is what you need:
An image printed on plain paper with and ink jet printer (my mother).
Golden Soft Gel (matte)
Also, note that you can do this same process using a photocopy from a copy machine that uses powder type toner.
You have to work pretty fast because the paper seems to soak up the medium . The above picture shows medium over the photo. I used my finger to spread it. It is pretty thick and so after I took the picture I dipped my finger into the water jug and went over it quickly for a more even spread. You may also want to try brushing the medium onto the canvas and laying the image into it. I do both. Actually, I think I may prefer to paint the medium on the canvas instead of the image. But I don't seem to remember that.
All the white layer is rolled off but I'm still rubbing.
