Question about Mask's negative space

[Trains1985]

Hello,

I am in the process of the output prining for a file with masking. The photo I am working with was orignally bright off-white, enough for me to be eliminated, without notice. So I masked out the visible objects, with the intention of getting rid of the ski around them, in this case. 

However, when I started prepping to send the file to my Epson 3880 Styles printer, the preview is showing what I think is the UNmasked image because you can clearly see two different colors at the border - the quality I tried to eliminate by doing the masking. I looked at the layers, and the seem to be all correct. I even tested the mask by adding a visible layer underneath it, and it works like it is supposed to.

Is there any way for me to get rid of the off-white areas? Any help would be much appreciated.

Hi,

There are a couple of tools you can use, depending on your familiarity with them -- I would suggest using Levels.

Press Cmd-L to bring up the Levels dialog box, or if you are familiar with Adjustment Layers, add a Levels Adjustment Layer. 

See in the picture below that the gray area is made up of 4% Cyan, 3% Magenta, 3% Yellow, and 0% Black. By moving the center slider in the Levels dialog box to the left (note where the sliders are in the dialog box) you can change those values to 0 (see the info box in the image). Notice that the left edge of your image is 0% for CMYK. Move the sliders to the left just until you see the numbers change to 0 and you will get rid of any "off-white" color.

Let us know if that fixes the issue or if you have any additional questions.
