The rosettes are represented by their size:
small (~10 mm), medium (~16 mm), large (~26 mm) and extra large (~42 mm).
By type the rosettes are divided into: "simple", "classical", "ornate", "woven", "laced".

Type and size of a rosette can be quickly identified by the file name:
rosN_M_K.ext, where,
N is the nominal rosette size from 1 to 4 (i.e. from "small" to "extra large");
M is the nominal rosette type from 1 to 5 (i.e. from "simple" to "laced");
K is the sequence number.

The rosettes are represented on the gray-filled ground object in two variants: against the white-filled object that outlines the guilloche shape precisely, and without any background.
The lines are 100% black. Lines width is 76 micron.
