These appears to be vertical, horizontal and diagonal lines. The vertical and horizontal lines appear much closer to each other. The diagonal lines appear farther apart. These stamps are known with horizontal or vertical mesh wove paper. Also, paper with laid lines on some stamp issues. On other issues, gum breakers/breaks/cracks are found which can be imparted into paper from gum and are visible even after gum has been removed as on used stamps.
LQ and SQ can be similar with regards to paper, perforations, etc. since they were made by the same printer around the same time.
For Large Queens Duckworth papers:
Stout horizontal wove paper with a somewhat yellowish tone and often with a faint diagonal ribbing
. The design is often visible from the back. The impression of the design is sharp.
Stout horizontal wove paper that may exhibit diagonal ribbing
similar to paper 4, but is white rather than yellowish and opaque, so that the design can not be seen from the back. It is the most common paper and all values can be found on this paper.
