It seems that ICC profiles are still a great problem in many top corporates in providing the necessary correct functionality ? Karthik bala guru -----Original Message----- From: lcm...@li...

This printer has some pigment inks that render bad on Hallo, we are using also the R800 and since one week 2 R1800 Printers. a) The best results we got with the "gloss Option" OFF. b) If we used RGB-Pictures with source "sRGB, AdobeRGB or ECI-RGB", we had the same problems with dark RGB-Colors. So we profiled the pictures from our Camera-Profile to "LStar-RGB" and then made the conversion to our Epson Rxxx Profile. This work was giving great results, which were not able to compare with the before results. So our motives are lots of dark wooden-furniture and chocolate pictures. Which are real good whith the new workflow, Camera->LStar->Printer. The Website from LStar is: http://www.lstarrgb.com There are the profiles and a lot of documentation on what it does.

Thomas, there's something that puzzle me : Without speaking about profile, how can you have darker black than the RGB(0,0,0)? We have done many tests by printing directly very Dark RGB values and the Darkest one is RGB(0,0,0). Id this one is not darker enough, you can use any profile you want, it want be enought black... >> But just doing some simple test by printing some Dark RGB values shows >> that >> >> there's some problem with deep dark colors on this paper, with photo >> paper >> you have good result.

Sorry Steve, I did not read all messages to this topic! So we had the problem, that the "Dark RGB" values where dark enough (dLog 2.4), but had no good differences in the dark areas. We are using "LowCost" matte Photo Papers, but use always "Premium Glossy Photo Paper" in the printer setup box, because of the color reduce from the driver, if we take an other setting.

> have you profiled the paper your self ? yes we have profiled ourself the paper. But just doing some simple test by printing some Dark RGB values shows that there's some problem with deep dark colors on this paper, with photo paper you have good result. This printer has some pigment inks that render bad on 'low cost' paper'. Epson earn more money by selling inks and paper, so I think they are now focusing on photo paper (more expensive so more interesting for them). |

also, there is one other setting i forgot to ask about : gloss. so far I am generally pretty happy with gloss off when using epsons archival/enhanced matte paper. but with photo paper, and/or gloss ... I have been less then impressed.

The best matte paper that we have found was the archival without gloss option...but the price is more than 2 times higher than the photo quality paper.. > also, there is one other setting i forgot to ask about : gloss. > > so far I am generally pretty happy with gloss off when using epsons > archival/enhanced matte paper. but with photo paper, and/or gloss ...
