Date Of Issue..right Or Wrong..?

I was looking through my plate blocks and blocks and came across some thing that caught my attention...Below is a plate block # 2 printed by British America Bank Note in Ottawa.

According to Unitrade these "Floral Definitives" were printed and released between 1979-1983.

The block below is Scott 782 released Aug.2.1979.



Then why do they have a date of 1977 as shown in the picture below..?..Which is the same date stamp as Floral Definitives by Canada Bank Note of Ottawa released 1977-1983...Should they not be dated 1979

I think Unitrade has made a typo error. The date of issue should read "1977-1983" as shown in earlier editions

Hi: In scott these are no.782b perf.12x12 1/2 1978. Photo.& Engr.
Scott no.707 1977 was Litho. & Engr. perf.12 x 12 1/2
Just different printing techniques but the same stamp.

The engraved and printed date is the date of the design copyright

Unitrade does give 2 sets of these Floral Definitives, the 1st 1977-1982 and # 707 (2c W Columbine) is dated 1977, Apr 22, with printing by CBN Co
2nd set is for Floral Definitives of 1979-1983 and the 2c Western Columbine is dated August 2, 1979 by BABN Co.
Therefore, 2 different printings, the 1st by CBN and 2nd by BABN + the extra info mentioned
The 1977 date as you mentioned (Robert) is the Copyright date, already mentioned in this thread.

Thanks guys..so it is a copy right thing..good to know.

Robert

I hadn't realised that either.

This is actually fun am sure both stamps, printed by 2 Companies, are not the same, perf, paper, method of printing etc etc. I have not returned to Unitrade book but it seems quite evident.....now let me see in my collection. Data under each stamp shows difference in perf.........

Rene,
You can see both printings of all definitives, on this Steiner Page...........

Absolutely Rod -

1) the 1st Definitives were printed by CBN(Canadian Bank Note) and have a strong tendency (Unitrade) to change colour when exposed to long periods of sunlight and perf 12.0 X 12.5
2) the 2nd Definitives were printed by BABN (British American Bank Note) using photogravure and steel engraving (Unitrade)perf 13.0 X 13.3 (background appears mottled)- 1st Definitives were printed Lithograph.

Amazing Page, Rod !! René

Fun time. Here is one printed in the year 977.

dynamode....

Of interest (also) is the mottled background typical of the 1979-1983 Floral Definitives printed by BABN, using photogravure and steel engraving. Ths is # 786 (Scott and Unitrade)

René

Here is one with a nice dark green shift left. Common ?.

Thanks for posting this shifted (left) black litho printed (CBN) #711, dynamode !

René

No problem Rene. I have a few more with lesser shifts ready to post if you would like to see them. I think they are probably common, but I like the visual varieties.
