Update on printing color on the Epson SureColor P800
I am starting a completely new thread to get away from the confusion
of the 'Wide gamut' monitor thread. The point I wanted to investigate was the which appeared in discussion with Floyd: whether an all sRGB work flow is the way to go if your screen and printer will let you go wider. So I have carried out two tests. First I used the well known test image from Steinmuller and Jurgens https://dl.dropboxusercontent.com/u/...2_ProPhoto.tif I printed this four times from PhotoshopCC in different places on an A2 sheet of Epson Premium Glossy paper. The settings were as follows: 1. AdobeRGB workspace, printer manages colors, AdobeRGB on printer 2. Prophoto workspace, printer manages colors, AdobeRGB on printer 3. Prophoto workspace, printer manages colours, sRGB on printer 4. Prophoto workspace, printer manages colours, ICM on printer. The ICM image was - yuk! It would only be good for printing images of cow dung. :-( Irrespective of the workspace, both the images printed with an AdobeRGB color space on the printer were drab compared with the image printed with sRGB on the printer. At this point it occurred to me that the original test image may have been made for an sRGB color space so I decided to make my own. I took three of my own raw images and processed them in Photoshop using a ProPhoto workspace. A JPG of this can be found at https://dl.dropboxusercontent.com/u/...0Composite.jpg I have used the image at the top right as a test print before and I used the other two mainly because I was most interested in reds and greens. I ran four prints again on A2 Epson Premium Glossy paper. All images were processed in ProPhoto workspace. The four test prints we 1. Colors managed by Photoshop using the Epson profile for the paper. 2. Printer manages colors with the printer set to an AdobeRGB color space. 3. Printer manages colors with the printer set to an sRGB color space. 4. Printer manages colors with the printer set to ICM specified color space. It was very hard to tell the difference between the image (1) managed by Photoshop and image (3) using an sRGB color space. For some details (1) was better but for other details (3) was better. I think (1) had the edge but by two tenths of a gnat's whisker. In comparison, the AdobeRGB color space set on the printer was as drab as those in the first tape. The ICM setting was again - yuk. On this basis, I would say Floyd was correct. If you are using Windows 10, Photoshop and Epson printers stick to an all sRGB work flow. This shouldn't be the best way but it seems as though it is. It looks to me as though Adobe have not yet embraced Microsoft's new XPS print specification and we are still stuck with the old system confined to an sRGB color space. When I first bought my P800 I was disconcerted to find that it contained profiles for about five papers and that my then favourite was not included. After talking to a helpful Epson engineer in Australia I found there were several distinct drivers out there in the wild including for Japan, USA, Europe, Asia, Australia, and New Zealand. These were all different with different combinations of paper profiles. Eventually I got what I wanted and settled down with the Australian driver. A few days ago Driver Detective told me that my Epson driver was out of date and requested permission (which I granted) to update the driver. I find now that I have a huge number of different paper profiles and that the user instructions have abandoned the advice to let the printer do the management. When I started using my new wide gamut screen with an AdobeRGB color space I also switched to AdobeRGB for the printer. I got better results on a key print (as I described) and attributed it to the wider color space. Now, I very much doubt that conclusion. It is far more likely that the changes are due to the printer driver. But I am yet to be certain. No doubt there is more to come. -- Regards, Eric Stevens |

How much gear do I need (assuming I can't find a local service to do this for me, which I can't)? you need a puck that can scan prints. if you're only going to use a few papers, it's cheaper to have it done (and they'll be using much better equipment than you would have purchased). such a service need not be local. print out the test sheets and mail them, and you get profiles sent back. |
