Axis labels are cut off when saving figure

Consider the following MWE with produces a figure:

clear 
close all

fig1 = figure(1);
set(gca,'xscale','log')
set(gca,'yscale','log')
xlabel('Frequency (Hz)')
ylabel('Amplitude (dB)')
set(gca,'FontUnits','points',...
'FontWeight','normal',...
'FontSize',10,...
'FontName','Times',...
 'Units','normalized');

PaperW = 16;
PaperH = 7.5;
fig1.Units = 'centimeters';
fig1.Position = [20 10 PaperW PaperH];
fig1.PaperUnits = 'centimeters';
fig1.PaperPosition = [0 0 PaperW PaperH];

print(fig1,'fig1.png','-dpng','-r300')

I'm trying to save this as a .png file using print. Additionally, I want the saved image to be 16cm by 7.5cm. I specified this using variables called PaperW and PaperH (the width and height).

The problem is, the bottom of the xlabel text is cut off. Why is this happening? And how can I solve this problem?

Zoomed in on the xlabel. Notice how the bottom of the q and y are cut off.

One solution has been found. The trick is to offset the y coordinate (by a small amount) and then offset the height by the same amount.

pos = get(gca, 'Position');
set(gca, 'Position', [pos(1) pos(2)+0.01 pos(3) pos(4)-0.01]);

No this doesn't work, at least for plots created by bode. It just squeezes the phase plot, but the xlabel left in its original position after executing saveas.
