No black ink only on Epson R1800?
I just tried twice to print a B&W image using black ink only on this
printer - or so I thought (color:black in "Print Settings"), and the image is grayscale. But the prints have a very pronounced blue-green cast in the grays. I'm using a Mac with OX10.3.9, Photoshop CS2, etc. My color prints are pretty good, since I've calibrated the monitor, tweaked the gamma, etc. But so far, the B&W printing is totally unacceptable. Any ideas how to get this thing to only lay down black ink? Karl Winkler http://www.karlwinkler.com |

Any ideas how to get this thing to only lay down black ink? Karl Winkler http://www.karlwinkler.com No - the option isn't there for R1800 - except I think it is for the Japanese version (PX-G5000/5100) using windows drivers, but probably for text printing only. The K3 printers (with three blacks) also use some colour for monochrome printing. The R1800 can do an okay job on monochrome. With mine using good ICC profiles and colour-managed printing though photoshop, I get near neutral results - a very slight shift to cyan in light tones. I can see it - but nobody else has ever commented when looking at prints. They are good enough for display, but not as good as R2400/HPB9180 monochrome prints. But, I'm 100% sure that my monitor is profiled well, and that my workflow is correct. It is absolutely critical for monochrome that the exact profile is selected and used with the settings that come with the instructions - if you use a profile made in "rpm" mode at "best photo", then the result will be wrong. It may also be a good idea to run a nozzle check, head alignment, and turn off bidirectional (high-speed) printing in the driver. Good luck. |

Re-reading the OP's post, nothing if they're printing a true greyscale image. But I usually tone a monochrome print slightly. YMMV. |

Different papers will print differently with th same ink. Evidently the Black ink is not a "PURE" black but attains its black color by combining several different colors. Different papers may exhibit a bias toward one of the colored components e.g. cyan... which would explain the blue-green cast. Bob Williams |

Any ideas how to get this thing to only lay down black ink? I'm not sure how far you are willing to go with getting BW results... but if you have a Linux system, the CUPS print driver for the R1800 can very easily be configured for virtually any color combination you like. Each ink can be adjusted for both density and gamma, hence it might cost you a few bucks worth of ink to configure it by the cut and try method, but it flat will do it. I've twice printed a BW on an R1800, and both were some time back. One was a high contrast print, virtually two-tone; the other was a normal contrast range BW print. I don't recall how I did either of them, but I don't remember anything tedious either. -- Floyd L. Davidson http://www.apaflo.com/floyd_davidson Ukpeagvik (Barrow, Alaska) |

Any ideas how to get this thing to only lay down black ink? Not much help, but on a PeeCee with Qimage (not available for Mac) and the Japanese drivers, the Japanese version of the R800 (the PX-G900) will do it. The only thing that might be of help is that I noticed that there are _two_ places to select black: on the first page of the printer setup tab, and in the advanced settings. At least in the Japanese drivers there are some perverse differences. For example, if you select roll paper in the first tab, it doesn't let you set the size (for panaorama printing) but if you set it in the advanced dialog, it does. So it might be worthwhile seeing if you can find multiple ways of selecting black and trying all combinations. Are you using genuine Epson inks and Epson paper? Different papers will print differently with th same ink. Evidently the Black ink is not a "PURE" black but attains its black color by combining several different colors. Different papers may exhibit a bias toward one of the colored components e.g. cyan... which would explain the blue-green cast. The R800 and R1800 have both matte black and gloss black inks, which print lovely blacks all by themselves. With the Japanese version of the R800 (and the "English" drivers it comes with) I get lovely (grayscale) B&W prints by printing in "black" mode selected in the printer driver. The PX-G900 black only mode is very nice indeed; I can't see any advantage to the R2400. Oops. If I had known that, I would have purchased the R1800, since the R2400 (a) requires changing between gloss black and matte black, and (b) can't use Epson's best glossy photo paper (called "Crispia" in Japan) which is very nice stuff in the R800. Grr. Anyway, I (a) hope the OP figures this out, and (b) reports back here either way. David J. Littleboy Tokyo, Japan |

If it hasn't been converted to grey scale- and many apparent B+W images are not- it may have a lot to do with it. Workflow being correct for greyscale images, though, is imperative. Make sure printing is entirely managed by Photoshop, or entirely managed in the printer driver would be the first thing to check. -- john mcwilliams |

Sorry, frederick and others, I had a lot of unread messages here this a.m, and didn't load fresh, so my post is redundant to a degree. So, Karl: Grayscale. Paper matched to ink. Check all driver settings. Please let us know what does the trick. |

Check all driver settings. Please let us know what does the trick. Guys, thanks for all the input. I've re-checked all the driver settings, color settings, etc., and made sure I have the latest driver and paper profiles. It's Epson inks and paper. None of this seems to help: a B&W print from a grayscale image with color:black selected in printer settings yields a print with very strong cyan tones. I've looked at the print under magnification and I can see that color inks were used because there are cyan and magenta dots along with the black dots. Interestingly, if I look at the color controls dialog box, then select "advanced" I see the color sliders. The C, Y, and M sliders are grayed out and so I can't adjust them. This should tell us that only black ink would be used... but it's just not the case. It appears that the only option is to print in color and set up a custom profile via trial and error. This of course will use up ink, paper and time. I'm sure Epson doesn't mind. So it comes back down to the fact that as far as I can tell, there's no way to select black ink only. I wrote a note to Epson about it, we'll see what they say. I mentioned in the note that I probably would not have purchased this printer had I known that it would not be possible to print with black only. I used to do this all the time with my 1280 and I got very decent results - with one color of black! -Karl http://www.karlwinkler.com |
