I've been trying to save a duotone image I'm working on and can't save it .tiff or.jpg.
Any one else have this problem or can help me figure out what I'm doing wrong?
I go to "Save as" and it won't let me choose anything but, psd/pdf/eps/raw. and the raw versions end up all corrupted.
ackk. help! |

just change it from duotone to rgb color mode and you will be good to go!
edit
oh--you said cs. i would assume it would be the same as 7, but i really have no idea. :)

Duotones are primarily used for reprographics in print, where one can use a Pantone colour with black (or two or more 'special' or 'spot' colours together). When exporting the file, EPS is the usual format so that the separate colours can be utilised in a DTP application such as InDesign or Quark.
It is not necessary to retain the duotone information for print on consumer printers and, as Alecia said, it can be converted to RGB once you have the colour balance you prefer.

Thank you both, and thank you imagineer for the extra info too.. I did finally figure out about converting back to RGB...
I'm working on some old b&w film shots that I scanned, which is new to me.
I think they're coming out pretty good.
Appreciate the help.

A duotone intended for printed separations (in EPS format) is actually a Grayscale file with two sets of "transfer functions" (the duotone curves) applied to it at the time of output. This cleverly allows the use of one set of 8-bit values to generate two (or three or four) sets of screening info, saving valuable (at the time) disk space.
By contrast, an EPS intended for full-color (CMYK or Process) separations must contain a separate 8-bit channel for each color, and thus is 4 times as big on disk. If you wanted to print your duotone in a coffee-table book, you'd have to convert from duotone format to CMYK -- try it and you should see the file get about four times as big. |
