Jitters Posted January 20, 2010 Report Share Posted January 20, 2010 Hi all, Not usually stumped by Photoshop (using CS3), but here's one for you. Have a scale of various screen tints of black from 0 to 100. The press guy wants it saved as a 1-bit tiff file for whatever reason. I can save as 8-bit without any problems, but the only way I can manage to get a 1-bit option is to convert color mode to bitmap and then adjust the dithering, which turns it into a halftone-like pattern - not what I'm after, but am going to check with the press guy in a few. Any way around this so that the grays are smooth and still in a 1-bit mode? Thanks for any help! Quote Link to comment Share on other sites More sharing options...

Any way around this so that the grays are smooth and still in a 1-bit mode? Thanks for any help! Just from a theoretical point of view, because my photoshop skills are somewhere near non-existent. It will be impossible to get a grayscale image in 1-bit because of what 1-bit means. Without going into too much detail, 1-bit means that each pixel has just 1 lot of '0 or 1' to choose from. That means it's effectively on or off, white or black. 0 = Black 1 = White 2 bit would give you far more options 00 = Black 01 = Black Gray 10 = White Gray 11 = White 8 bit gives you 256 different options, so 256 shades of Gray from Black to White. So your press guy either: - Doesn't know what he's talking about - Wants to test whether you know what your talking about - Wants a 2 tone image The other option, of course, is that I'm completely wrong.

chimpanzyyyy Posted January 21, 2010 Report Share Posted January 21, 2010 Any way around this so that the grays are smooth and still in a 1-bit mode? Not sure about that, but I would say it's not possible? Quote Link to comment Share on other sites More sharing options...
Jitters Posted January 21, 2010 Author Report Share Posted January 21, 2010 Thanks for the replies. It is indeed not possible because of exactly what you described. After a phone conversation with him, turns out he wanted it in 1-bit with a a round dithering pattern. Once they add some dot gain at the press, the pixels will appear to blend uniformly. Well, know we know. Thanks again! Quote Link to comment Share on other sites More sharing options...
