MATLAB: Painter’s export problem

Question

Dear Matlab central users,

I have created the following patch object:

Faces =[1 2 3 4; 5 6 7 8;9 10 11 12;13 14 15 16]; 
Verts = [-1 1;0 1;0 2;-1 2;0 1;1 1;1 2;0 2;1 1;2 1;2 2;1 2;2 1;3 1;3 2;2 2];
AV_color = [ 1 1 1;0 0.05 1;0.5 0.05 1;1 1 1];
figure
pch = patch('Faces',Faces,'Vertices',Verts,'FaceColor','flat','FaceVertexCData',AV_color,...
            'EdgeAlpha',0,'FaceAlpha',1);

I have prepared patch for painters export using accepted answer in: http://www.mathworks.com/matlabcentral/answers/92720-how-can-i-export-a-figure-containing-a-surface-with-rgb-cdata-to-an-eps-file-using-the-painters-rend

rgb_colors = get(pch,'CData');
[i,map] = rgb2ind(rgb_colors,64);
set(pch,'CData',double(i));
colormap(map);

Unfortunately, black edges appear around each figure upon painters rendering:

set(gcf, 'Renderer', 'painters');

I need the edges to be the same color as the faces. How can this be done?

Thanks,

Phil

Painters does not support transparency. Can you set 'LineStyle' to 'none'?
