Title: Glossy paper that warns not to use pigment ink
Post by: darlingm on September 20, 2012, 11:59:56 pm
Ran across a nicely priced glossy photo roll and was about to try one, when I noticed it says you have to be using dye rather than pigment inks.  I have the Epson 9900, which of course uses pigment inks.

Always being curious, I looked into it a bit.  Found a bunch of sources saying that printing with pigment ink on glossy papers is problematic because the pigment ink doesn't dry properly on it.

Yet, we all print using pigment inks on glossy papers and canvases all the time.

What makes the difference?  Since pigment ink sits on the surface anyway rather than soaking in like dye, why would it dry differently on a different type of paper.

I'm guessing they're using the term "dry" wrong.  I was wondering if it's more an issue that it wouldn't stick well without a pigment ink compatible receptacle coating... But I print nozzle checks on the cheapest xerox/inkjet paper I can find, which I doubt has a special pigment compatible coating on it, and I don't see any issue there.

Or... Is this warning out of date, and will the 9900's pigment inks maybe do OK?

You often get what you pay for. Buy papers specified for the inkset you're using.

It may be that the paper you are looking at does not have the correct porosity to absorb the pigment particles into the surface and that dyes will adhere to it without a problem.  I second Mark's point, use only papers designed for pigment inks.

I also agree the other's, if it says do not use pigment ink, there is a reason. Here is a link that gives explanations of the
different coatings. http://www.shortcourses.com/display/display2-6.html
