Hi,  I'm trying to make a T Shirt Transfere. I have a black line drawing of
a boat saved as a PSD file, the background is clear. The line drawing is not
perfect and whaen I try to change it with the bucket tool to white (for a
black T shirt) all the lines get a lot fatter and not so crisp.

If you can help I'll send you the picture, if you want.

Thanks

Gus

The first quesiton I would ask is whether you need to invert at all.  Don't
you want to screen white paint onto a black shirt?  If that's the case, no
inversion is needed, or rather the inversion will happen automatically when
you switch ink colors.

Assuming you do really want to invert the black line to get a white one, the
paint bucket is a brutal tool.  It will fill in shaded areas with a solid
color. The paint bucket also has no respect for transparency. These two
factors give a rough pixellated appearance to lines that used to have smooth
edges.

Gadgets suggestion of using invert will give you a cleaner result, but on a
transparent background you'll still see the lines get thicker.  Try it and
see.  This happens because of the mathmatics Photoshop uses for white versus
black on a transparent background.

If this thickness is a problem, add a new white layer, move it under the
image containing your lines (you may need to alt double click the background
layer to allow this), and invert to get a perfect copy of your black line in
white, against a black background.

Now if the black background is an issue, I'm back to wondering if you really
want to invert, or just use white paint.
