Major tip for Ultimat Gold when cutting multiaperture mounts.
Say for the sake of arguement that you are creating a long, narrow style mount for three photos, all identical sizes and orientation, e.g:-
* aperture sizes need to be 80mm long by 140 wide.
* external borders need to be 45mm on all sides.
* space between each window mount needs to be 30mm.
Start by drawing all of the external lines at 45mm (rather like drawing lines for a single aperture mount.
Next, it is inportant to check you Ultimat manual, because there may be a quirk about where to draw the lines for one side of each aperture.
It would be easiest to do the lines for the long sides of the mount first, since there will be no variation in distance from the top or bottom of the apertures.
When marking out the cross cuts.
1. Set side bar on ultimat at 45. Draw guidelines for outermost cuts (one at either end).
2, Pay attention: this is the science bit!
It may be a peculiarity of the Ultimat cutters, but one needs to offset the line for the second side of an aperture in a mulitaperture sequence (if you get my drift), in order to allow for the difference between lining up the marker line against the cutting guide, and the actual blade cutting position. (Used to wreck my head when I first started cutting MA mounts). Basically for the second line, you add the aperture value to the setting of the previous line, and then SUBTRACT 1mm.
e.g for 3 landscape photos in a line as per above, the settings for the cutter bar when drawing lines for the short sides should be set at:
First Cut - 45
Second Cut - 45+140-1 = 184
Third Cut - 45+140+30 = 215
If the arrangement is totally symmetrical, you can draw the settings for both sides by swapping the board thru 180 degrees each time you reset the cutter bar.
Easier to demonstrate, but hope you get the idea. If you don't take into account the -1mm offset, you will end up with uneven borders between your apertures.
