How do you inverse a clipping mask

May 19, 2013 8:40 PM

I'm working on a tshirt and can only use 3 colors (Green, Black and Yellow).  If you look at the attached image, I need to make the brown color that is inside of the squirrel mask out the items behind it (corn stalks, rectangle and part of the "R" in "Corn Maze".  The tshirt will be grey so once the Clipping Mask is applied, it will allow the grey tshirt to become the color for the squirrel. 

 

The problem I'm running into is if I duplicate the squirrel and use him as a clipping mask, it does the opposite of what I'm trying to accomplish.  I need to mask out everything inside the squirrel, not everything outside the squirrel.  In photoshop, I could just inverse the selection.  Not sure how to inverse a Clipping Mask. 

 

Any help would be greatly appreciated.

    Clipping masks only work in one direction. Encompass what you want visible INSIDE the clipping path. Everything outsdie the clipping path will be hidden. There's no way to invert a clipping path.

    Students,

     

    Depending on the non squirrel artwork, you may have different options.

     

    Obiously, the squirrel must be in front of or behind all the objects you wish to (partially) invisibilize. It is in front of the corn to the left and the (O and) R below and behind the corn to the right and the QUI above. To work on all parts, you will have to put the squirrel in front of (or behind) everything.

     

    You may use:

     

    A) Clipping Mask using a shape with a squirrel shaped hole in it;

    B) Opacity Mask with a white (or black) squirrel (no Clip, Invert/non Invert);

     

    If the rest of the artwork consists of closed paths, you may also (requiring deletion of squirrely bits and pieces, but yielding simple paths):

     

    C) Pathfinder>Exclude overlapping shape areas (or what it is called in your version);

    D) Object>Path>Divide Objects Below.

     

    In any case, you may consider (re)applying the features, eyes, snout, and mouth, and possible the outline (you may use a nofill squirrel on top).

     

    An, especially with the outline applied, you may consider leaving the stacking order so the squirrel appears to come out of the corn.

     

    Is this the giant squirrel we all thought was extinct?

    Assuming that the squirrel is a vector graphic:

     

    Set its fill (and only its fill) to zero opacity.

    Then group everything.

    then set the group to knockout group.

     

    Forget about the clipping mask.

    The tshirt will be grey so once the Clipping Mask is applied, it will allow the grey tshirt to become the color for the squirrel.

    So simply fill the squirrel with white. So long as it is not defined as a spot color, white will not print as a color separation, but it will knock out anything behind it.

    Students,

     

    This thread seems to confirm the value and justification of (many) different answers, including different interpretations of what is needed (which may coincide with what is asked).

     

    One aspect is the use of the document. I for one always try to reckon with possible untold (future) needs, such as an image on a coloured background for web advertising the T shirt and similar.

     

    By the way, nice play on the names of mahiz.

     

    The Fox Squirrel Corn Maze thread lives.

    Then it would be about how I would pronounce it, anyway ;-)

    Knockout Group can be found in the transparency palette. You may have click a few times on the arrows left of "Transparency" to expand the palette to get the extra options.

    In German: yes. But non when I#m trying the skquawirrrrrel in English ;-)

     

    @Students:

     

    Everything needs to be grouped:

    For just the squirrel (not its nose or other details) you set the fill to opacity 0

    Sorry for the German panels:

     

    Aussehen = Appearance

    Ebenen = Layers
