Removing specific color tone from the entire picture using Photoshop

[diligentsloth]

Hi,

I am trying to print the following image on a piece of paper that matches the color of the background color of this image:

Is there any way I could remove the background ivory color tone from the entire image so that the printed image looks similar to the original one? I cannot just print the original image on white paper because I am trying to imitate the texture and patterns(what looks like dark speckles in this image are pieces of gold leaves mixed into the original paper) of the original paper using a piece of paper that matches the color and patterns of the original one.

Thanks!

Hello, I would duplicate the document, so that you work on a copy, then use the magic wand with the contiguous option unchecked, and select the background, shift-click on the gold leaves to add them to the selection, create a layer mask to hide them with the background. 
another option would be to select the leaves, hide them with a mask, re-select the layer, and use the white point of curves to lighten the background, and tweak the curves to keep a similar contrast (the darker paper will influe the tone and contrast of the print)

Thanks for your suggestion!

Just be aware that inkjet inks will look very different on coloured paper as they do on white paper. You may need to adjust the colours.

Hi, I have an idea that I hope might help.

I would try to use a Photoshop 'hue and saturation' adjustment layer because you definitely don't want hard edges to any selection you make in order to target the tint you wish to adjust.

Select your target tint (the colour you wish to reduce) like this -

in the adjustment dialog: choose any colour in the dropdown, then use the + and - eyedroppers to select and adjust the actual colour you want by clicking on the image layer.

Now I'd temporarily apply a crazy colour adjustment to reveal what areas have been selected.

Next simply use the saturation slider and it should now be possible (if you got the selection right with the eyedroppers) to reduce the saturation of the specific colour you are targeting.

As it's an adjustment layer you can at any time adjust the layer opacity slider to reduce the adjustment effect - although in this case its pretty easy to just change the saturation adjustment slider as you make print tests. Don't forget to write on each test print how that slider was set, so you can go back to what worked.

In principle,  it seems you need to remove all the "beige" of the images background throughout the image (even within the photo items) because printing on a paper with colour will re-introduce that base colour throughout the image.

You are attempting to remove the (final printout) paper tint throughout your image - then when printing on that paper it puts the tint back.

Imagine printing a face onto a pink paper (we do that here in the UK with the Financial Times), the pink paper tint would make the face too red - in that case you'd need to try reduce the red tone in the original image a little - step by step til it worked.

I think what you are attempting is in many ways the same thing. In your case, keeping the texture of your background and removing the beige tint so it works on your chosen paper.

ps, best to duplicate then flatten the image before printing each time, it's good practice, but don't flatten the original you save as loses the layers - thus losing the ability to adjust later or even remove the adjustment layer and take you back to the original.

Please let me know if this works for you

I hope this helps
