Wow! If those are plate cracks, and they sure look like it that plate was in pretty bad shape. Good find, Robert!

Yes those marks look like the typical plate cracks that produce the "hairlines" mentioned in most Canadian catalogues. This 1 cent Edward with hairlines is listed in the 2015 Unitrade as #89iv. |

You mean just "hairlines" and not "hairline cracks" in the plate..??
Is there always that many of them though..?? |

Unitrade lists this as 89iv "hairlines". I've seen as few as one to as many as 20 across a stamp. Nice find. Slight premium for Used Fine at $5.00 in my 2014 catalog. (Used VF is $10) |

Hairlines are the result of a cracked plate. The plate is bent to fit the transfer roll and the cracks show up. |

Wert, those are hairline cracks. They still happen on modern issues - one of the most famous ones is the "raincrack" on the 4.9 cent Buckboard precancel, Scott # 2124a.

just for my own edification is that the same thing as a "gripper crack" or is is that just when the plate wasnt wiped down properly? Thank you in advance for any responce. -Jeff |

I_Love_Stamps..I think they are referring to stress cracks in the plate...In high school I took the printers course (for 4 years) and we did encounter stress cracks in plates, sometimes as we are securing them or if one side of the clamp was tighter than the other side, we would get the odd crack in a plate. |

It has nothing to do with improper wiping of the plate. They are stress cracks on the plate from being bent numerous times |

Final update guys..Had Ralph take a look at it as you can see from the new picture and what he says.. Quote:
This one does indeed have a slight re-entry, visible mainly in the upper part of the design, including the lettering band and the top of the portrait oval. However, even more interesting is the very heavy retouching that was done to this stamp. Notice the very thick top frameline. Also, the heavy dark arcs over the final 'A' of CANADA and 'P' of POSTAGE and the cross-hatching between them. The same sorts of things are also going on in the lower part of the design...the cross-hatching between ONE and CENT, the bottom lines of the lower left and lower right spandrels, and the bottom frameline. Then you have the added bonus of several hairlines in the left and right margins, the result of a cracked plate from bending it to fit the rotary presses. The cracks took up ink, creating these lines.
Lots going on here...all in all, a very interesting stamp!
Ralph
