Hi Torban,
Are you making postscript files? The lines often look very thin in those. There's an FAQ about editing the postscript files themselves to thicken up the lines:
http://ferret.pmel.noaa.gov/Ferret/faq/changing-line-thickness-in-postscript-files
The labels are drawn using Hershey fonts. These are simply lines drawn to form the letters and numbers, so there are not separate font elements that can be edited. Thickening the lines overall may improve the look of the labels. You can adjust the size of labels in Ferret - see Chapter 6, Customizing Plots for the details:
http://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/customizing-plots/
Another thing to consider is PyFerret, which is available now for download, and described here: http://ferret.pmel.noaa.gov/Ferret/documentation/pyferret/. Pyferret does its graphics in the same way as classic Ferret, and draws lines in the same way, but calls a different lowest-level graphics library. It can save images as .png or .pdf files. Have a look at the images in the documentation pages, such as this page,
http://ferret.pmel.noaa.gov/Ferret/documentation/pyferret/example-sessions-ferret/, to see if you think that would be a good option for you.

Dear Ferret Users,
I have a few questions regarding the optimization of plots:
1) Is there a way to increase the contour width beyond a value of three (I use the /thickness=3 command)? I plot several maps with the viewport command and the contours are very thin in the final plot despite using the largest thickness.
2) I have the same problem with the longitude and latitude labels. They get very small. I tried increasing the font size in Adobe Illustrator, however the labels are not recognized as a individual font path. Is there a workaround to get nice large labels?
Thank you very much!
