I wonder if you've got me beat? I have 46 years in the photo/printing biz from an apprentice at 16 through letterpress (Heidelbergs and Glockners), Litho (Heidelbergs and Fuji) to densitometer controlled limited edition printing for the Fine Art Trade Guild. Switched to prepress and management with Dainippon galley cameras, drum scanners and final film planning - then switched to study with an MA (now an MSc) in Digital Imaging at the London Institute. I also had a Deskwriter - a 510 model with black only and upgraded that to an A3 Epson 1200 with 6 colour printing. The subtractive CMY model in photography is not comparable with the CMYK print process as it uses continuous tone and specially coated materials to give it a much wider gamut of colours - print processes use plain paper and the tones have to be generated by dots to fool the human eye. Also the CMY inks for printing were never really perfected due to the wide choice and quality of papers and methods like gravure and web and the difficulty of printing heavy wet on wet areas - drying time was a big bug to printers thus the 100% black with maybe a ?% tint of C, M or Y or all three to produce a 'rich black'. I've never come across a CMY inkjet printer but obviously they must exist if you had one - they perhaps didn't last long as less colours seem to contribute less to the final image in inkjet even with the coated paper. Epson have some models which utilise 2 greys and black to produce better quality monochrome - not unusual as high quality BW printing of photographic books also used duotone and tritone. If only I could justify buying one. http://en.wikipedia.org/wiki/CMYK_color_model Pete -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Re: G4 10.4 or 10.5 looking for way to halftone a picture to print in BW
What program are you trying to get the halftone image to print from? Photoshop on it's own has some capabilities in this area, and if you are going to do a lot of images, and or you want more control on the finished look, you might consider Andromeda's Screens filter/plug-in for Photoshop, it gives you a great deal of control on the size of the halftone dots, the pattern, the threshold level, and more. The filter is great, but it's not cheap.

Re: G4 10.4 or 10.5 looking for way to halftone a picture to print in BW
FIRST let me thank all who replied both on list and off list. I will look in to the several suggestions as soon as I can, but I did want to get this out: Yes, my hp printer C-4180 All in one, does have a GREY-SCALE selection, and I did experiment with it long ago using a color pix and expecting it would print in-- what else-- Grey scales of some 256 shades, but NO, it printed in all black or all white the very reason I have appealed to the list for assistance. BTW: I do NOT find any instruction in HELP to print in BW! So as I say, I gave it up. To Santa, was the sample you sent me printed using ONLY THE BLACK INK CART? I bet it was all colors making fake black -- HOW DO YOU KNOW FOR SURE? You do know that if you print using all three colors you get FAKE BLACK! In my case, the color cart is DOA, dry as a rock, maybe that should be DAR, BUT IT has to be in the printer to get the Black cart to work.

G'day Jonas I think you're looking for greyscale printing - newspapers did indeed use a low res BW halftone screen - about 80 lines per inch I think and black ink only which gave the appearance of tone to the human eye by varying the size/distance between dots. This was analogue imaging though and digital is very different but your image editor should have the ability to convert an image to greyscale - 256 levels of grey calculated from the RGB channel values - and your printer dialogue should have the option to print in greyscale only - I have three printers and I know that at least two have this option.
