Map background color

[BobT]

When I try to print the maps I have made they always have a light cream colored background which also prints.  I am using BaseCamp to print, I have tried personal printer and large plotter with the same result.  It takes forever and uses a lot of ink.  Is there a way to get the background to be pure white and not print.  I use the free cgpsmapper and MSTK.  I have tried using both transparency options with no difference.  When I look at some of the TOPO maps on here they also seem to have this light cream background.

You can define background object in TYP file and give it white color. Background is a polygon 4B.

I have never used polygons before.  I use a .txt file and convert it to .typ file in MSTK.  Is the format below what I would add to my .txt file?  The maps that I make are maps of GPS tracks.
Also, how do I make the polygon on the map, I assume I have to draw a big rectangle in GpsMapEdit the size of my map and select is as a 0x4B.

Thanks for all of your help.

Yes, it should be something like that, but I'm not able to verify details. For TYP file editing I'm using TYPViewer https://sites.google.com/site/sherco40/home, it allows for direct TYP editing. TYPViewer creates following code for white background:

[_polygon]
Type=0x4b
Xpm="0 0 1 0"
"1 c #FFFFFF"
[end]

You can get Typwiz from http://pinns.co.uk/osm/typwiz3.html
which is a free download you can edit and create type files graphically it is very good in my opinion it also allows you to change the fid which has to match your tdb file fid

Thanks for everybody's help.  I will play with it this weekend.  I do have typwiz, I will play with it and typviewer.

Popej, thanks.  I cut and pasted your post into my type file and it worked perfectly.  Maps now have a pure white background that does not print.

This is a great site with so many knowledgeable, helpful people.
