Black and White (and Blue)
Hi, I've been experimenting with black and white printing using my Epson
1280 printer and I am unhappy with the results. I've noticed my prints have a distinct blue tinge in grey areas and I recently printed an A3 sized mozaic of more than 160 BW crops from pictures of a recent holiday which really is very blue when viewed under daylight (although it's not as noticable under tungsten light). I made the pictures black and white using the Monochrome option under the Channel Mixer in Photoshop 7. I kept the Blue Channel input to a minimum because looking at the Channels, blue is the worst channel. A typical picture would be about 40 per cent red, 50 per cent Green and 10 per cent blue and they look fine on the screen. Is the blueness due to the limitations of my printer for Black and White printing? I'm happy with my colour prints, but Black and White just lacks any impact and is too blue. Before I give up completely and take my black and whites to a printing lab in future, can anybody explain what is going on? Thanks |

Is the blueness due to the limitations of my printer for Black and
White printing? Yes. Although it depends on the paper, what ink batch you have, etc. To my eye, they look a bit purplish.. It is VERY difficult for any colour printer to use colour mixing to get neutral greys right through the range. You have a few options: - careful manipulation of the color balance may help (eg if it's blue in the midtones, add yellow to the midtones), but you will most probably simply shift the color problem elsewhere. - try different papers, some of the matte papers seem to be better - print everything in sepia tones! - put printer into monochrome mode too, but then your image will suffer and grey shades will dither - if you're willing to dedicate your printer to b&w, get a third party ink system (they use various shades of grey ink to get nice neutral greys) - just accept that these printers are good for colour, not so good for b&w. The second last one is the only real solution. |

You just need to go into printer properties and ensure it is black ink only

1. Going to black ink only (as suggested in another post) may cure the color
problem but it will result in a grainy print. These printers are designed to print using all colors to obtain smooth tonality. That said, it is difficult to obtain a true neutral black on these printers. 2. Don't confuse the ratio of colors in channel mixer with the shade of black (blue, purple or whatever cast) in the print. The color cast in the print is a result of the printer printing "profile". Worse, the color inks, when mixed to produce black and white, tend to exhibit "metamerism", which mean that the color cast changes depending on the light source used to view the print. 3. If you want to continue to use the1280. it may be best to convert it to B & W inks exclusively, as suggested in another post. 4. Perhaps the best option, if you don't mind spending the money, is to get a printer that handles B & W better. I use an Epson 2200, and print using Colorbyte Software's "ImagePrint" product. This is a Raster Image Processor (RIP) that does produce outstanding B & W prints without metamerism, and excellent color as well. The down side is cost. The printer is $500, and the RIP is about $500 for the lite version (which is all you need). There is also another product available (basically a profile, I believe) that is much cheaper and can produce good B & W from the 2200 but does not address color. Good luck.
