Default Does the canon i850 print B&W prints well?

I have read a couple of different reviews and opinions that seem to contradict each other about how well the i850 prints B&Ws. I am looking for an affordable printer that does B&W fairly well and the price range looks good for the i850. Can any one help clarify how well this prints B&W's. Is it true that the printer mixes colours to make B&W's?

Thanks

Yes the printer does mix to print black and whites that does'nt mean you won't like em it just means that the black and whites are going to have a magenta or cyan cast to them. If you really want a printer for doing B&W prints I would reccomend either the bottom line epson series printers or the Cannon i950.

NO! The printer does not mix all colours to create black and white photos. If you want to print a b&w photo with black ink only, your input image MUST be also b&w or in grayscale ONLY.

Yes sadly it must use 3 colors to do a B&W print since if it uses its large black ink droplet size which is like 20picoliters vs the color ink drop sizes are 2 picoliters. Try printing a black and white photo with your color ink tanks out of the printer then do it again with them in the printer.

You are wrong. If I want to make a b&w print with BLACK ink only I select grayscale and it prints with black ink only even in highest quality. The graphics on plain and coated paper are far better when printed in b&w using black ink and a lot faster too rather than using all 3 colours. So I really recommend printing b&w with black ink on plain and coated paper - it really gives crisper and sharper output.

BUT, if you want to print a high quality photo on some glossy paper it will mix colours to get b&w prints which is normal.

PS. The 20 pictoliter droplets are dropped so precisely that you really don't notice them at once.

Really cause the standard human eye can see down to the 3 picoliter drop size. A trained human eye can see down to the 2 picoliter drop. So I wonder how they make them so precise that I can't see them :roll:

I said: 20 pict. are not so visible on PLAIN PAPER not photo paper.


The dots on plain paper aren't so visible as on photo paper because the ink spoils a bit and therefore the dots aren't round so it's not so easy to see them when the image is printed in highest quality.

Hi it says In Steve's reviews that:

"The i850 printer introduces a new printhead with a unique combination of 5 picoliter droplets for coverage and ultra-fine 2 picoliter droplets for photo-realism"

how do you know it has 20 picoliter droplets?

Thanks,
Steve

Yes I also don't know where did you got this information from? I also think that these are 5 picoliter drops.
