Flat Plate Vs Rotary Press

Jogil, the information presented is rather confusing. My question therefore is, if I compare a dry versus wet used examples of 195 to the 195d, which are both Stickney Rotary Press printed, what should I see? I am assuming that the dry printed is taller simply because it did not shrink?
On a different note, what is this Maple Leaves magazine? I have never heard of it before. Can you give us some information about it and maybe how to access it?
Thanks.

DeEll: The wet and dry rotary press printings would be both affected by the stretch in curved plate curvature so that both are around the same length but on the other hand the wet one should be slightly narrower than the dry one because the shrinkage occurred against the vertical grain of the wet paper in the horizontal direction on drying.

Maple Leaves is the journal of The Canadian Philatelic Society of Great Britain (CPSGB) at http://www.canadianpsgb.org.uk/

Also, see the article Evaluating the Medallion 1¢ Variety. A look at how the stamps were printed. Charles Neyhart, BNA Topics, Vol 71, #4, Whole #541 (Oct/Dec 2014), p. 45(6).

I find that using the transparent U.S. Precision Multi-Gauge to be very useful since it has different measurement templates to match against for different design sizes and the Kiusalas perforation gauge on it is also helpful.

Stop copying and pasting pages from a stamp journal without permission from the publisher.

Thanks for the info jogil !

Renden: Thanks.

Canada 150.. Why are you attacking jogil on a regular basis? You seem to have a hidden agenda!

No attacks, just copying and pasting from journals is questionable due to copyrights.

It gets down to fair use...where the line is depends...

(in US copyright law) the doctrine that brief excerpts of copyright material may, under certain circumstances, be quoted verbatim for purposes such as criticism, news reporting, teaching, and research, without the need for permission from or payment to the copyright holder

(copied from Internet)

Also, by having co-authored the above article, this can also give some kind of leeway in the copying matter.

Good one, Jogil.

Canada150: Stop accusations without verifying. You are constantly making rude comments on this forum.

Jogil has done some outstanding original research on perforations and printing process which should be commended.

Jogil's original post crops-out the authorship information.
In the absence of this author data (or any statement by jogil as to who authored the piece), CANADA150's concern is quite valid.
I have no problem with an author sharing their own work, but clear disclosure of authorship is a matter of academic professionalism and would have avoided a considerable amount of flak. Why hide it?
