Paper white as background in Photoshop
« on: February 03, 2011, 08:57:13 am »

I hope this finds you well and not snowed in. Or if snowed in, not stir crazy.

I was curious as to what you great minds think of the idea of setting a custom background color to the paper white values for the media being printed on? Could this be useful for viewing an image using the fill screen view option?

In a pinch, I'd say it could be useful if and only if you softproof and simulate paper white?
If not, the mismatch between image white and paper white would be errrr... counterproductive.

However, I do find useful to assess images on a white background ; the impression given is a bit closer to that on a reflective paper (tip learned here, thanks to who gave it).

You can measure the paperwhite with a spectro. E.g. EyeOne + iOne Share.
Right-click on the background in PS and pick the Lab values from the measured data.

Ps. If you don't have access to the gear, I can measure the papers if I have them.

In the same mood, what is the best way to take out the paper "white" of a scanned drawing etc in Photoshop ?

Ernst:
Taking out paper white from a drawing can be tricky. In curves, try and move the white part (top) of the curve to the right until you are pure white. Sometimes that compromises the tones of the image, then you can try and drag the top part of the curve down to compensate.

For watercolor paintings, and sometimes use the dodging tool set to dodge white areas at appropriate setting. This usually doesn't affect the darker parts of the image.

Must be other ways also!

Would think you would have a magic action already in PS for your work! ;-)

No John,

That's why I asked this. Every time I take a different path and something tells me there should be some logic in it.


BTW, for adding the paper white Lab values like Sven advises you can get them from SpectrumViz. UV included readings though.

Do you mean picking the value of the paper or make the scanned paper white? Washed out? Colored?

An easy and reliable method to take out the paper "white" "off-white" in the image of a scanned/photographed drawing, print, watercolor, etc that when printed on an inkjet paper "white" or "off-white" the two "whites" are not added to one another. Problem is that part of that original drawing white will influence the original colors say up to where they become opaque, that differs per original but should be taken out too. The scanned image shows light colors but doesn't tell anymore whether that is the result of mixed in white paint or the white paper showing through transparent colors.
