I created the image above by desaturating the colour image of the man and then adding a new purple layer and selecting 'vivid light' from the layer palette drop down box. In doing this the man became purple but the white area surrounding him stayed white...I then adjusted the layers on the first layer so that the white part became purple - the final result is what you see in the attached image.
The problem is this - I need to create this effect for 15 or so images all with a specific purple pantone colour, I need to create these for print ready artwork. All the pictures (ie the man) I will be using, need to look the same kind of shade. The way I was creating these before was to adjust the bottom layer so its grey rather than white so that the white area becomes purple.
Confusing huh, If you dont understand my question (and I dont blame you!) then all I need is to create a set of 15 images that look like the attached image (using a specific pantone) but I have no idea how the best way to do it is.
How would you guys achieve that? Any help greatly appreciated.
But as for achieving that in RGB:
One could create an Adjustment Layer to make the image black and white (either Hue Saturation of Black & White for example), a Curves-Adjustment Layer to control the contrast, a Solid Color-layer of the dark blue-color and set that to Blending Mode Color (if no black areas turn up increase the contrast in the Curves-Layer), then a Solid Color-layer of the lighter violet and set it to Blending Mode Multiply.
Those Layers could then be simply dragged onto any other images.
But the result would of course be no good for printing in actual Spot Colors.
The company this project is for have a certain corporate dark purple colour (of which I would like the 'man' to be mostly made from) and the lighter surrounding purple can be any pantone of my choosing.
Anyone know the best way to go about creating this?
You could make a Selection of a black&white-version-of-the-photograph’s luminance, inverse it and, in the Channels-Panel’s PopUp-menu, choose Add New Spot Channel for the Foreground color and select the Pantone color.
Then Add New Spot Channel for the background-color and fill that solid black and hide the layers that contain the composite of the photograph.
This should leave You with blank composite channels and the two Spot Channels visible.
Indesign can handle either psd- or DCS2-files containing Spot Channels.
The problem I perceive here is that depending on the print-process and the background color selected it might proof necessary to knock out the foreground elements if the company is very strict on their CI colors. Unfortunately simply inversing the foreground selection would probably not work as this might leave the mixed-color-areas greyish.
Are the prints gonna be offset or silkscreen?
I'm pretty sure it will be offset.
I'm not a photoshop pro so I will try and follow your instructions - thanks very much for that! Any additional info tips or input would be much appreciated!
