How to convert Images to PANTONE in Photoshop
This is probably one of the easiest ways to convert a color image into a single or multi color PANTONE. You may want to do this is if your planing to print a job in a single color or Multiple PANTONE’s.
I’m using Photoshop CS6, but I believe this works on other versions from CS4 forward.
This is the original image that I’m going to use.
The first step is converting the image from his current color space (CMYK or RGB) to Grayscale.
Image > Mode > Grayscale
Your going to be prompted by Photoshop, if you want to proceed and Discard color information. Click Discard.
If you want to adjust the conversion you can go to Image > Adjustments > Black & White.
After this go back to the same menu, but this time choose Duotone.
Image > Mode > Duotone
Once you convert the image to Duotone the follow options window will pop up.
Here you can find several options and some presets as well, you can also create your own presets.
Bellow that is the Type.
The default is Duotone, but you can choose from Monotone (Single Color) to Quadtone (Four Colors).
The Ink is where you choose the color and the adjust the curve for the color tone. Being the first square the Curve Adjustment and the second one the Color Picker.
On the Duotone curve option you can adjust the percentage of the tone range and you can even reverse the curve from some really cool effects.
On the color option is where you can attribute the PANTONE colors to the image and map it the way you need to achieve the best result.
To choose a PANTONE simply click on Color Libraries and Choose a Book and from that book the color your are looking for, you can also type the PANTONE reference if you know what color your are looking for.
This way you can map any image to a single PANTONE Color or several colors, this is handy if your planing to printing a artwork in a single color and you want to to match the images with that color. Some times you might want to do this to save on the printing cost, note that this only applies if your planing to go Litho. (I might do an article on that later). Let me know in the comments.
You can also achieve a few cool effects, you can use the four color to create something like the below.
I hope you liked the tutorial, and if you have any questions or doubts, or even maybe suggestions for some more tutorials, please let know in the comment section.
