I didn't put the test strip directly in a window, but on my desk in my studio (which has windows on three sides) to sort of mimic normal wear on art that is not UV protected.<br /><br />I tested rapdioliners, copic, faber-castell pitts, triplus, penstix and pilot pens. The winner by far was, and continues to be, the FB pitt pens when straight india ink is not available. Rapido used india ink (which survives), but they are no longer produced. All the others faded, the worst of which being the penstix. It turned sepia in as little as two months! Perhaps a cool effect, but only if you're expecting it. ;)Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2999230124118604245.post-86619106119870323092009-08-16T19:41:24.270-04:002009-08-16T19:41:24.270-04:00Perhaps if you did the samples you made today, but...Perhaps if you did the samples you made today, but on several different papers, just to see how the paper made a difference?

I’m not at all surprised by the dyes (marker pens), but I am impressed by the colored pencils’ performance. There are layout pencils for sign painters that are indelible to water based, or oil based, paints that are designed to fade-out with exposure to light. I have even used color markers for this on very large projects on rough surfaces such as stucco. The most durable paints for exteriors are oil-based enamels, but they are harder to work with when blending, and especially over-glazing. For most paint systems the reds seem to fade the most, followed by the blues. There are also clear over-paint coatings that have UV inhibiters. The most versatile I have found is an industrial vinyl coating which can be applied over acrylics and oils, (and also painted over with acrylics and oils!) and it is flexible so it san be used on canvas. <br />The best part of this post today is the link to your past postings on color, what a fantastic voyage! I strongly suggest my fellow bloggers take the time to explore Mr. Gurney’s archive.

They were instrumental in the creation of an official ASTM standard for colored pencil pigments. Members of CPSA can purchase the latest results of lightfastness testing for all the major brands. I'm no longer a member (since I'm now strictly digital), but as I recall cost for the results booklet was about $12. I'd hate to see you reinvent the wheel, so you might want to check them out. <br /><br />I find it ironic that "traditional" media are held in high esteem by museums, while digital is not considered "real art." Perhaps the inks used in inkjet printers are fugitive (100 years or so from now, they'll fade), but I was at an exhibit of the Dutch Italianates here in Pittsburgh, and one painting had blue leaves, due to the fugitive yellow disappearing.

I use these materials for my comic book pages.<br />(I'd trust Indian Ink from any well known brand.)<br /><br />* Schoellershammer gray/brown recycled acid free sketching paper : fairly permanent. I put a piece in the sun for half a year now and it gets slightly more brown, but not lighter nor darker, so it is suitable for highlighting with white paint or crayons.<br /><br />Note that glass is a fairly strong UV light filter. Thick multi-layer windows are not ideal for testing.Erik Bongershttps://www.blogger.com/profile/02409523352634066030noreply@blogger.com
