when printing a figure matlab prints line that are not shown on screen

Hi i am trying to print a map. when i do set(gca,'Position',outpos,'box','off');

I see no frame around my map (pcolorm) but then when i print it the left and bottom lines appear

I even tried to manually set xcolor and ycolor, when they are being set to lets say blue the frame apears blue but once i try setting the to white the same black line appear. what do i do?

the code i am using:

fg=figure

set(gcf, 'renderer', 'zbuffer');

m1=axesm('mapprojection','mercator','MapLatLim',[31 34.5],'MapLonLim',[30 36],... 'frame','off','plabellocation',1,'mlabellocation',1,'parallellabel', 'on','meridianlabel','on','frame','on');

cb=colorbar('Location','east');

caxis([-.1 1.5]);

inpos=get(gca,'Position');

outpos=[.2 .015 inpos(3) inpos(4)];

set(gca,'Position',outpos,'box','off');

inpos=get(cb,'Position');

outpos=[.05 .2 inpos(3) inpos(4)*.9];

set(cb,'Position',outpos);

data2plot=surface_noriv(:,:,itime)-surface_nile_before(:,:,itime);

data2plot(fsm==0)=0/0;

pcolorm(latpom,lonpom,data2plot);

shading interp;

showaxes('off');

textm(31.5,35,num2str(itime*2),'FontName','Times',... 'FontWeight','Bold','FontSize',16);

filename=['/tmp/time' sprintf('%03d',itime) '.png']

saveas(fg,filename)

Set XColor and YColor to None:

set(gca,'XColor','none');
set(gca,'YColor','none');
