Does colorizing using Hue/Saturation make your image one color?

I have an image that needs to be printed. The more the colors I use, the more expensive the printing. The images are quite intricate.

If I colorize the image in Hue/Saturation, does this make the print just 1 color? Do printers count this as just one color?

I hope it does. If it doesn't, what's the best way to get the least amount of colors for an image?

The Hue/Saturation+Colorize command does not “separate” an image, so it will still be RGB and will come down to a CMYK or other “separation” method to create distinct/separate channels that would equate to a printing separation/plate.

Grayscale is one channel/separation/plate.

As mentioned above, you can create a duo/tri/quad image from a grayscale image, using special transfer curves to decide where the colour appears.

There are of course other methods.

Can you provide a sample image, this whole discussion is highly dependent on the source image.

How is this being printed? Screen printing?

Offset printing.

This is the image. So what i did was colorize the birds assuming it would then be counted as 1 color. And thought that this image just has 2 colors: the birds and the waves.

Agreed… Post #4 mentions offset printing, which is what my comments were based on (my original stab in the dark guess was screen print).

This graphic would be better created/separated in Illustrator as vectors, rather than as pixels/rasters in Photoshop.

You’re right and I had missed that and needlessly asked again – sorry for that.

True, vector data should provide superior output, but if recreating the layout in Illustrator (if the source material is not actually vector anyway) is worth the trouble is up to the OP.

If you want to limit the print colour, duotone is the way to go.

Duotone is one option, but with certain images it may make more sense to separate them manually with Spot Channels (if certain elements should be b/w only and others have color for example).

No.

Please post the image in question so people may actually be able to provide pertinent advice.
