| 468516 | 2006-07-06 00:30:00 | "Less black" = pale black? I find such "pale black" difficult to visualize also .... Just buy more colour cartridges Cicero. Get that gorse out of your pockets... May look into a laser printer,seem reasonanbley priced these days. All I want is cheap form of text reproduction. |

| 468518 | 2006-07-06 04:25:00 | GF: you don't mix black with a colour to get grey. You mix black with (another non-colour ;)) white (paper) to get grey. The fineness of the screen (or dot scatter in an inkjet) makes the process more or less visible. The reason for having black as well as primary colours in inkjets is that the "black" made by mixing (subtracting) the primary complements is never black enough. It looks terrible and muddy. CMYK has black (K) for that reason. A "laser" printer might not need a black toner because they use addition of opaque pigments, rather than subtraction of translucent dyes. On a monitor, which adds R, G, and B, you get the best black achievable on the screen by turning them all off. |

| 468519 | 2006-07-06 04:53:00 | I thought as much. I doubted you mixed say red and black to get grey. |

| 468520 | 2006-07-06 06:22:00 | Are you picking on me because I am colour blind....? :dogeye: But I suspect you may be right, I was thinking of RGB not CMK (too many years of colour TV study is my excuse...) Grey is r200, g200, b200 on the PC ..... Are you saying that the printer will use black "a bit" only to reproduce that, because that does not seem to happen. They seem to want the colour cartridge.... |

| 468521 | 2006-07-06 06:39:00 | Picking on you GF? :confused: I wouldn't dare . :dogeye: Your RGB grey is "half-black" (or "half-white" if you're an optimist), and you can produce the grey scale between black and white by varying the "number" (which is the same for all three guns) . The thought occurs: Does an LCD screen use CMY rather than RGB? They are transmitting light, rather than emitting it, so they would have to use subtraction . The major difference is in the way dyes and pigments work as the colour agents . A lot of inkjets do insist on having a complete set of ink cartridges to work at all . Even though the printer manufacturers make their money by selling ink, many problems can come from running out of ink . Apart from clogging of the printheads, thermal ones can burn out if they are fired without ink to cool the elements . The piezo ones are probably immune from that but the pores are so small that they would dry out and clog very quickly . (Of course, my reference to a "laser" printer in my last posting was to a colour one; black only ones use a software equivalent of the traditional screen technique to get "halftones") . |

Have a look under a eye glass or pick a grey in photoshop and have a look what it is made up of. P.S Cicero you can make greys up of mixing black and red or blue for that matter. |

I hate to pop your bubble Plod, but if printing grey scale requires colour, somebody forgot to tell my monochrome laser, or a monochrome inkjet. They do greyscale just fine. Grey is just less ink on white paper. We are not mixing light here, this is subtractive colour mixing, relying on the absorption of light, not additive as in colour TV. You lose your perspective if you get your nose too close to the problem. :D The only inkjet I know of that needed colour to print grey was the very early HP that didn't have a black cartridge at all and produced an awful-looking grey-green "black" for text and even worse colour rendition. Metla would have loved it, but he was probably just finishing school back then. Cheers Billy 8-{) |

Cheers Billy 8-{) You obviously didn't read my earlier post (pressf1.co.nz) , I know where you are coming from, but there is a difference to printing grey and printing greyscale. This is how I make my living, Grey is not just less ink on white paper. |

| 468525 | 2006-07-06 10:33:00 | The fact is I am losing colour when I am set on greyscale. Canon Ip4200. |
