The past week has been pretty busy, and not much has happened with the portfolio work in some time. The time that I’ve had to spend on photography has been centered around getting other prints made for sale, and struggling with paper and ink issues. I went to make a final print on a paper that I had done extensive testing with (Ilford Galerie Gold Fibre Silk(GFS)) on 8.5 x 11″ paper. I ordered a box of 13 x 19″ paper just for this particular print, this was the first time I had tried the paper in anything other than letter size.
I recently began reading the book Real World Color Management, along with several other web sites on the topic. All of this reading had reminded me that I never did a thorough analysis of the various media settings available when creating a paper profile and printing an image. So I spent a couple of days making test prints and waiting for them to dry before selecting the best paper type to use when printing on GFS. It turns out that the media setting I used when I first created a profile for this paper wasn’t really the best one (though it did offer the deepest blacks). So with my newly found paper setting I created a new profile for GFS and that is where the problems started. After printing the test sheets and allowing them to dry for 6 hours or so, I took a look at them under a strong light and with my glasses on. And I found something I had never seen before on this paper… the dreaded pizza wheel marks from my Epson printer. Pizza wheel marks are created by the feed mechanism Epson uses in their lower end (if you can call the 3800 that) printers without a vacuum suction transport. What pulls the paper through the printer are two sets of opposed rollers, rubber on the bottom and spiked wheels on the top. These spiked wheels sometimes dig into the ink and paper and leave columns of tracks that are affectionately known as pizza wheel marks.
Normally these marks are only visible when looking very closely at the print under direct lighting at a specific angle. These marks only show up on glossy type papers. In this instance I had not seen them in my initial evaluations of the paper, and was fairly annoyed that they’ve only showed up just as I’m preparing a print for a client. So I went back and made a few changes to the paper thickness settings hoping that would alleviate the problem. I wound up picking a paper thickness of 0.5mm and a platen gap of “wider”. This seemed to get rid of the marks. With my new best possible profile for GFS in hand I made what I thought was the final print of the ForestFlora5 image. My initial inspection under the light showed nothing wrong with the print, so I boxed it up to let it sit for 24 hours before its final spray.
A couple of days later I removed the print and put it up on the line to shoot it with a dose of Premiere Art Print Shield which is a spray designed to add a layer of scuff protection and lightfastness to inkjet images. Once on the line I could see two small white spots on the print. Hoping that they were just dust or something on the surface I backtapped, then blew, and finally brushed the print with my hand. Nope, the ink had not adhered to the paper in two pinprick sized spots. Before I printed on this sheet, I cleaned it as I normally do with an anti-static brush (with orthogonal brush strokes). Then I blasted the paper with a can of compressed air as a final cleaning measure before putting it into the printer. This sequence of prepping the paper has worked quite well for me over the years, and I rarely ever get flakes on my cotton rag papers, let alone leave dust on a glossy type paper before printing. Assuming that somehow I just had some bad luck and some piece of detritus had found its way on to the paper just before printing I grumbled about wasted time and went back to make a new print.
On my second “final” print I followed the same paper cleaning procedure. Then after the printer was finished I carefully examined the print under my light (with my glasses on). And sure enough there were two other small defects in the image, these weren’t missing inks but defects in the paper (as I now suspect the first problems were). These defects are quite small less than a square millimeter in area and practically impossible to see on the paper before making the print. By now I was getting kinda mad and kicking myself for trying to do a job on a new box of paper in a size I had never tried before. I sat down and made a third “final” print and hopped that there would be no issues with this one. The third sheet was good, and suffered from no paper defects. It is now dry, sprayed and bagged, ready for delivery.
When using new products, you never know what is going to happen, or trip you up. I sincerely hope that these problems were just isolated incidents since I really like this paper’s look and cost. However, the issue with the pizza wheel marks remain, and my search for the perfect photo black type of paper for me might not be over after all.
