I have a sentence which means **"to use a laser to transfer an image from the computer and have it be imprinted on any material; wood, plastic, glass, metal, anything else"** What is the correct way I should say this?

 - To imprint an image **onto** the material?
 - To imprint an image **into** the material?

Or maybe there is some other way? Maybe with words: transfer, apply, put, embed.

I should ask as well, Is there a big difference between the two when we speak about merging two object?

 - Squeeze the ink **into** the water?

or 

 - Squeeze the ink **onto** the water?
