Admiral 106A Booklet Panes Diff Shades &

I have 2 Admiral booklet panes 106a that are different shades and appear to have two different colour papers, the darker shade is in whiter paper and the lighter shade is on the more yellow paper.
Is it the paper or is it the gum ?

Whoops forgot to put pictures on..sorry

It appears you have both wet and dry printing process stamps here. I quote THE ADMIRAL ISSUE OF CANADA by George C. Marler page 35, "As the dry process eliminates much shrinkage which occurs during the drying of the paper after it has received the impression of the plate and has been gummed, stamps printed by the dry process are not only wider but visibly wider. With vertical wove paper, such as was used for the post-office sheets and rolls and for later booklet panes, the shrinkage occurs across the grain or horizontally, with the result that stamps printed by the wet process are narrow compared to those printed from the dry process which are wide. The early booklet panes were printed on horizontal wove, that is to say, with the grain of the paper running across the stamp, so that shrinkage was of the length of the stamp giving it a "squat" appearance."

Hi, Mike…thanks for response. I've only got the Unitrade Catalogue as reference….106aiii mentions Squat printing.
Only the reference table mentions wet and dry printing and according to this table there where no dry printing on 106a. However the text underneath the table, which is similar to what you have quoted mentions that dry printing appears embossed, so which of these, if any , would you say was dry printing. Again thanks for response.

The early booklet panes were printed on horizontal wove paper and shrank vertically.
Stamps being short and wide. The lower booklet in your image. Unitrade 106av.

The other booklet is probably printed on vertical wove paper which shrank horizontally. Stamps appearing tall and narrow. The top booklet in your image. Unitrade 106a.

I suspect both are wet printing but can't be certain as I can not tell if there is embossing (not visible in the image provided).

Welcome others to comment here.

Many thanks again Mike, only just getting into different papers so all help is gratefully received
