plot tick justification error in EPS file

On a plot, I have replaced x-ticks with text and then rotated them through 90 degrees. When printing to EPS format (top image), the text is centrally justified and crosses the x-axis. When I print to PNG (bottom image), the text is right justified and does not cross the x-axis. Furthermore, the font in the EPS image is incorrect; it should be Garamond but appears to be Courier New. How can I correct these two issues?

Hi Benjamin,
This happens because the X axis ticks in the figure are set to 'Auto' and the X axis is rescaled when the figure is resized for exporting.
To avoid this refer the following code snippet to set the X Axis ticks to ‘Manual’
X = 1:5;
Y = X.^2;
f = figure;
ax = gca;
names = {'One';'Two';'Three';'Four';'Five'};
ax.XTick = [1:5]; % Ticks
ax.XTickLabel = names; % Tick Lables
ax.XTickLabelRotation = 90; % Rotation
ax.XTickMode = 'Manual'; % Manual X Ticks Mode
ax.FontName = 'Garamond'; % Font

Hi Kiran,
Thanks very much for your response.
The fix here seems to be the use of the opengl renderer rather than the painters. For example, I cannot replicate my issues by removing the
ax.XTickMode = 'Manual';
command and using the opengl renderer.
However, there is a side-effect. The quality of the opengl EPS image is no better than a PNG image. So if inserted into a PDF docuement, the image is noisy when zoomed. It is not when using the painters renderer, but the alignment is incorrect.
Saving the image as a PDF file has exactly the same issues.
Why is the image quality so poor? Is there a solution?
Thanks again.

I have noticed that setting
ax.TickLabelInterpreter = 'latex';
ylabel('some text','interpreter','latex');
both solves the layout and font problems when using the painters renderer.
