Adding a border in Lightroom

1) Print Module
http://blogs.adobe.com/phosphors/2011/10/photo_borders_in_lightroom.html

My fav method:
Print module
*** Print Setup -> Select/create a dummy printer with 0 margins.  Add 4x6, 5x7" with 0 margins.  (Existing printers don't allow me to have 0 margin, so it adds extra margin as in Fig1)
Image settings on right panel
select Stroke (color and size)
Print Job -> Save as JPEG
Just adding a solid color border I don't need special border from photoshop (as in 2 links above)

Pic on the left: Using Method 1. Note the extra stuff outside the border

Pic on the right: Using Method 1 with dummy printer that allows 0 margin

Downside:
- I can't export as exact 800x600.  My print job is specified by paper size + dpi.
To have 800px for web-posting with border, use 6 inch * 300px/inch = 1800 px.    800px/6in = 133px/inch.


*** Always use 300dpi for actual printing.  



2) Print Module with identity plate

Both methods above are the same.  (using photoshop border in lightroom print module)

3) Adding border by vignetting

Since border=vignette here,  this is useless if I want to add a separate vignette unless I can stack different vignettes.
TODO: See if I can stack presets for the same adjustment.  I think no.

Using Method 3) Vignetting. Perfect black border, but no vignetting

I wish I don't have to go thru Print menu.  I wish adding border is a preset and can be exported together in library module.
