I have just downloaded this software programme to help me in the identification of the small queens especially in respect to their perforations.
On a good quality stamp how accurate have people found it?
I have to say it is quite impressive in how it works.
Thanks,
John

johnamichael I believe Stan ( stainlessb ), our France Aficionado (  ) uses this program (PERFOPMaster4000) - I hope he gives his opinion to your question With EZStamp, I have EasyPerf V 3.7.7 (not free) and find that most stamps can be measured with a good gauge (and save time !!). I even have a Small Queen gauge (done by a member of another Forum) It incorporates the Kiusalas gauge as well as has it independ. You will not find it on the NET. I received a copy directly from him, before I joined TSF. Tried to find it again -believe (not 100% +) the guy passed away. From all my references on measurement of SQs.....much debate and many types of perf measurements exist. Hillson (the book) is not even in favour of using Kiusalas for measurement. This must explain why I am at my 3rd round of evaluating Small Queens !! BTW Unitrade is incomplete as a Canadian Reference book on SQs - Their table is very confusing !! This guy (a member of TSF) wrote this some years ago and it is a good reference: canadianphilately.blogspot.com/2015/09/distinguishing-printings-of-small-queen.htmlRené

It is not easy. The article is quite interesting although I probably less good with paper than colour.
Thanks, Rene.

Yes, i use Perfomaster (I am on a Mac) and it measures perforation quite well, though with heavy obliteration I sometimes have to scan the back of the stamp to get obliteration interference (which I think may be 'antagonized' by the fact I typically scan against a black background.
I also have Stamp Analyzer which is useful for perfing and printed area dimensions.
Having said that, both softwares are a bit quirky with respect ot printed dimensions.
you must assemble (scan in) your own color 'library' (datatable.config is the name of the file inside Perfomaster) and it is important to calibrate both your moniror and scanner to the same standard (I use sRGB). I does a decent job as a color comparator, giving a ∆E value, the closer to 0.0 the value, the closer the match.
I do find the program a bit buggy and prone to occasional crashes, and I have not seen any updates

Thanks stainlessb. I also use a Mac, and aside from having some problems saving reports/images the solfware works quite well. I have only had a chance to play with one stamp (2¢ small queen) so far, it measured the perf 12.5x12.5 repeatedly with a very minor variance. Since this is not a known perf, I did wonder about the accuracy. I played with the colour reading but it will take some time to get it set up. I will have a look at Stamp Analyser. One thing I can say is that it works quite well. I will have a go with some modern stamps so see how it goes. |

As a user of PERFOMaster4000 (Linux version), I too can attest to the application's usefulness johnamichael and have had nothing but positive experiences with the software. For measuring the perforations of a stamp, short or pulled perforations can affect the results and in which case, the electronic perforation gauge posted here by WERT comes in handy to verify the results. The colour analysis tool is a also useful component but as stainlessb points out, does require a bit of setup to ensure true-colour recognition... Have fun and happy collecting! |

Here are the results of 2 of the aps, I am not sure how to interpret the stamp analyser perf number, but maybe I have set something wrong. The perfomaster suggests that the stamp is 36d with a 12x12.25p, late Montreal-Blue Green. Can someone explain the Stampanalyser reading to me. Both programmes are a lot of fun to play with.   |

and here is a different stamp but certainly there appears to be some consistency.   |

johnamichael scan the back of the stamp and compare perf results. The black lines from the cancellation may be interfering, and as Vince mentioned, short perfs will throw it off a bit

The perfomaster suggests that the stamp is 36d with a 12x12.25p, late Montreal-Blue Green. I cannot comment on the Stampanalyser view as I have never used the application myself.
However, as you explore your collection of the 2¢ Small Queens, you may want to have a look at this article published in an earlier edition of the British North American Philatelic Society's journal, BNA Topics (Vol. 8, No. 7 July-August 1951) entitled, CANADA SMALL QUEENS - THE TWO CENT GREEN by the Reverend Dr. George F. Dewey. In the article he states,"... Boggs says that the 12¼ perforation does not appear until the second Ottawa printings, (1888)."
From own collection, all the perforated stamps - 12 x 12¼ (measured pre-PERFOMaster 4000 days) are denoted as being from the Ottawa printings...
Have fun and happy collecting!

Very interesting article, I can see now that a definitive analysis probably does not exist!

stanley64 Very interesting discussion on the 2 cents perf green SQ: 12X12 1/4. I re-read BNAPS article of 1951 (Boggs says.....) and compared his opinion with Hillson's www.canadianpsgb.org.uk/small_queens_print.htmlHillson is also co-author of Canada's Postage Stamps of the Small Queen Era, 1870-1897 - He seems to have a different opinion of the 2nd Ottawa Printings........ 12 is pretty well universal with the 2nd Ottawa. (page 4)
EDIT:
BTW I do have Boggs and this Small Queen discussion(s) should be under the Small Queen thread and not the PERFOMaster4000 Canada's Small Queen discussions never end, colors, paper, perfs etc:) - Happy stamping - René

By the way I agree this discussion re the 2¢ green is in the wrong place. I was solely using it to illustrate the use of these 2 applications. |

I did sort the stamp analyser, the error was being introduced in the perforation reader by the fact that I had not reset the DPI, it worked perfectly at 600.

To appreciate the multiple perforations produced in Montreal during 1873-1888 Ref: Hillson and Nixon  |
