Distilled water turned Canon canvas slight yellow?!
« on: March 18, 2013, 06:01:32 PM »

Why would spraying distilled water on the back of Canon Artistic Matte Canvas change the base white into one shade in the yellow direction?  Like if the canvas was 255/255/255 white (it isn't), turning it into 255/255/254 yellow.

Makes it look like a light stain, where the distilled water treated areas and non-treated areas meet.


I've been known to use the distilled water trick on the back of Breathing Color Lyve or Crystalline to take out a ripple or crease, without ever having an issue.

Have a customer who wanted to push price down by using cheaper canvas.  I've had a roll of Canon Graphic Matte Canvas for a while that I got at a heck of a discount holding for such an occasion, so used that.

Wound up cheating further by re-spraying the entire back of the canvas.  The entire canvas stained light yellow, but it's uniform now on the front so you can't see anything wrong.  The stain-effect is now on the sides.

I'd usually re-do, lesson learned, without a second thought, but this customer's actually happy to buy these screwed up ones at a discount.  (He'll re-paint the sides white.)


But, I'm still confused how distilled water would turn it yellow.  It's a special spray bottle -- purchased specifically for distilled, well labeled as such, never anything else in it.

Very odd.  Is that a high OBA canvas?  Perhaps it somehow reacted with the fluorescent dye and negated it's effect?.  Do you have a way to check your water's pH?

any chance the yellow staining came from the canvas fibers?

also has this happened on this one print or everything printed from this roll
