Help In Identification Of Canada Reply Coupons

An interesting philatelic sideline is the International Reply Coupon.
Unitrade lists 45 different items plus many varieties.
There's one that's got me stumped: #14



The varieties are on the back:



#14 --- Arabic text is typographed.
#14a - Arabic text is lithographed
#14b - Arabic text is both techniques combined (& smaller)

I wonder if anyone can say how to tell the difference between typo- and litho- graphic printing.

How can the Arabic type be BOTH lithographed and typographed at the same time.

In Yao's Catalog of WorldWide Reply Coupons (2016) this is either coupon #15 or #16. Coupon #15 is the tall Arabic type and Coupon #16 is the short Arabic type. The other differentiating characteristic between the two #s is where the "." is at the end the English text. #15 has the "." under "n" of the line above in the English text and #16 under the "u" of the line above.

Glenn... The position of the dot is a characteristic of the 12¢ coupon (Unitrade #8-11). As to how the type can be both typo and litho, it is a question for Mr. Harris of Unitrade (who scans these topics occasionally).
I am asking what the difference would look like...
