Grayscale photo manipulation
« on: June 10, 2014, 01:38:44 PM »
Have a small order where we are scanning a color photo to be printed with one color at 55lpi (black headshot print on white shirt).  I am not an artist so what should I do to the photo to get the best results.  We have CS2 Suite so if anyone has any photoshop tips I am all ears.  If not I will likely just change the mode to grayscale and play with the curves and run with it.

I'm not sure if CS2 has this, but before you go to grayscale, go to Image/Adjustments/Black & White. There, you can adjust the lightness and darkness of the grays that will result from each color in the image; move the sliders around and it should be pretty obvious what you can do with it; say a red in the image is coming out black when going to grayscale, move the red slider to the right and it will be lighter. Check it out, if it's available in CS2. If not, then yes, go your other route. You could also alter the R,G or B channels separately in the levels or curves box, lots of options. But if you have the Black and White function, go there first...

I'd personally just make sure the file is in Grayscale mode and use the B/W curves options to make adjustments.  Then I'd make sure I adjusted my final output for dot gain as a single color photo print can get messy pretty fast if that adjustment isn't dialed in.

I haven't tried the process outlined in the above post though, so you may get better results with that.

No black and white option in CS2 so I will try the other suggestions.  Thanks!

I'm running CS5 and 6, and just couldn't remember if CS2 had it or not. Make a duplicate before you go to grayscale, so your original is still around. For youse others who have that in your menu but haven't checked it out, check it out. I can't remember where I got that tip, but it gives you a lot more control so you don't "just get what you get" when you go to grayscale.

I downloaded a free vid program to try out on this. Hope it works. It loaded to youtube so here we go.


This is just a quick vid to show some basic techniques to converting the photo to a 1 color.

I see it didn't take the audio. Will need to look at that later.

I'm not sure what taking off the S does for it. I did it and can't seem to hear the audio still. It's an AVI file and youtube said it doesn't recognize it but would try it anyways and so it shows the vid, but not the sound.  I will have to see if I can convert it to something it reads better. Taking off the S, puts it in the window here, but I don't know what the benefits are for doing that. Might be best to view in youtube. I donno.
