Do colours show through when using layers?


Recommended Posts

Hi there,

I am in the middle of a huge project and all of a sudden have a major concern.

When I am using layers and the background is a photo of the colour blue (rectangular shape).

Now as a new layer, I am pasting another photo (a smaller rectangular shape) on top,

with say a car in the middle.

Then saving this 'montage' as one jpeg.

Now, when printing this image, would the blue colour that is physically under the smaller

car photo shine through underneath?

Or would it only print and use what is physically shown, despite me knowing that underneath there is another

darker colour?

Thank you for clarifying.

(As the end result should just show the smaller rectangular photo with the car and that one being surrounded by a blue border.)

N.B. Please note I am asking, rather than just testing it by printing, as I am not using a printer,

and would need to drive somewhere to test this, which I like to avoid.

Thanks for your help to clarify this. It's possibly quite obvious but with not knowing it's a major concern for my project.

What you see is what you get. Layers are flattened before printing. If you don't see the blue, the printer won't be told to print it.

If it printed each layer on top of the others, you'd be able to soak the paper by having 50 duplicate layers.

Just to say. Each pixel in a layer has an alpha value which controls the transparency of the pixel.

So it you are reducing the alpha value to say 50% you will get a 50% of the layer pixel and 50% of the pixel in the layer below.

There is also the blend mode of the layer which impacts the final color of the pixel.

But as Rick said: Wysiwyg (What you see is what you get).

Think of it this way. Each pixel of the image gets 1 shot at the printer. The 1 pixel sent to the printer is calculated from all the layers.

Also, when you flatten (Image->Flatten) or save as a format that does not support layers (e.g. JPG), layering information is discarded. So if you print a JPEG, the pixels that were "under" other pixels (on layer(s) below it) simply don't exist anymore, so there's no chance they'd get printed.
