For example i only need to print Cyan colour separation only. I used a big office inkject. I would like to print it for review purposos. I would go to print then output then i select In-RIP separations for the mode. I didnt touch the other setting, thou i will list them incase it might be usefull, Emulsion= up(Right heading), Image=Positive. I would only tick the colour i only need for example Cyan. But when it got printed It will print all the other colours too. This create alot of wasted paper and ink. Also. the reason i choose In-Rip separation is that if i choose separations as the mode, it came out as black and white. Thou even in this mode, it still printed the other colour even thou i untick them. Any help will be very much appreciated.
Also, an extra question if its okey. I am printing an artwork that only uses spot colour. But the colour separation preview still showed CMYK colour. I have remove all the unused swatch from the swatches panel. Is there a way to remove process CMYK from the colour separation so that in the print output it doesnt show up. thou The first question is the one i really need solve.
Use "Separations (Host Based)" rather than inRip-separations.
If you don't have this option you can print to a "generic postscript printer" to get these options, once you have printed separations to a generic postscript printer you can convert the file to a PDF. There are also plugins from Astute Graphics and/or Esko that allow exporting separations.
The method described here unfortunately may not work since there have been changes to the PDF printer., if you are lucky (you have an older system with older drivers installed) you have a PDF printer that allows export separations to PDF. Which means that we need to go through postscript https://youtu.be/6v9US-dKczo
