1969 "Stamps for Cooks" - help wanted

Post by earsathome »

Hello All,

I have a couple of queries regarding the 1969 Stamps for Cooks booklet and wondered if anyone can help.

1. I think I have the uncoated variety on the 'Method' pane of 5d stamps but I am not prepared to try the silver test on it as I do not want to damage it.

The S.G. G.B. Vol. 3 has the following note regarding paper -
Quote:-
Unwatermarked chalk-surfaced paper was used for all values. Exceptionally, examples of all four panes from the £1 "Stamps for Cooks"
booklet and the 3d and 10d from sheets exist on uncoated paper. It does not respond to the chalky test (that is applying silver to see if it will produce a black line) and may be further distinguished from the normal chalk-surfaced paper by the fibres which clearly show on the surface, resulting in the printing impression being rougher, and by the screening
dots which are not so evident.
Unquote.

I have scanned part of the two panes together and perhaps someone can recognise if one is uncoated - not easy from a scanned image I know



2. The 'Method' pane of 4d values shows a red line running down through all three stamps on the fourth row. I know I have read something about that somewhere but cannot track down the source and it is not mentioned in the specialised catalogue.


Any information would be much appreciated.

Cheers

Ron.

E II is not my area of interest, but it could be an error of the doctor blade....

The 'silver' test extensively referred to by SG is a flawed conception. ANY COATING WHICH CONTAINS AN ABRASIVE SUBSTANCE _ NOT JUST CHALK _ WILL PRODUCE A BLACK LINE (this is the coating on the silver item, caused by a reaction with oxygen, being removed.

As far as paper coatings are concerned a magnification of ten should show the difference of surfaces as they are very different.

Uncoated Paper on Cook Booklet

The first pane from the Cook Booklet I ever touched was on uncoated paper. I split a Cook Book to put on FDCovers and the 5d pane was very hard to place on the cover. The next pane was entirely different and went on smoothly and with no effort , as did the other panes. When I got them back I realised the 5d was different and sent it to the expeert at that time writing for "Stamp Collecting". It was verified as uncoated.
The paper feels thinner than the normal pane and more flimsy. There is quite a difference put side by side.
I later found also se-tenant pane on uncoated paper.

Hope this helps

Ian Harvey has asked me to post this reply because we're having some problems with the Board. -- Ron, the vertical red line will undoubtedly be a "doctor blade" flaw - that is the ink wiper got a bit of dirt under it and dragged the ink down the stamps.
On the Cook book, there is no need to be sophisticated about recognising the uncoated paper panes. Forget the stamps, compare the tabs at the left as this gives a large amount of blank paper. In good normal daylight like today, normal panes are very white paper and uncoated are positively grey by comparison. If you can't tell much difference, you have not got uncoated. The panes came from the beginning and end of the rolls of paper and should have been discarded.

Hello All,
Thanks for those swift responses -

Asmodeus - I would have thought that myself too, but there is something niggling me that I have read about that line. Unfortunately we have so much printed information around the house, I cannot track it. Could have been from a dealer in the past.


Robin - Thanks for that tip regarding the 'silver' test, worth remembering. Personally I would not treat any decent stamp that way anyway. I must admit though that I have used marker pen on a common cylinder block to illustrate the phosphor cylinder

Your mention of the ten magnification reminded me that I had bought a magnifier at the last stamp day I went to so will give that a try.


Jean - What a story yours was with the FDC pane, a real turn up for the book.
How lucky to find the se-tenant pane uncoated also.

Ian - Thanks for all that information and I will look closely at the tabs. I do have the British Stamp Booklets series by Jean Alexander and Leonard F Newbery in which
they mention the fact that the beginning and ends should have been discarded. I appreciate your mention of it too.

I do appreciate all the help I have had on this discussion group.


As you will know it is always a problem handling these booklets too much and it is hard to get decent scans of the panes when the booklet is not 'exploded'
I will take a closer look at the 'thickness' of the pane (in between viewing the World Cup games) and if I find out anything else I will pass it on.

Thanks to all.
Regards.
Ron.

Ian,

Thanks for the tip about the papers on the tabs.

Unfortunately they are all white so it looks as though I do not have an uncoated paper pane.

Thanks to everyone for their help.

Whilst on the Cook Book subject does anyone know if the "green eye of the little yellow cod"
on the booklet cover, as illustrated, is very common?



Regards
Ron.

Ron,

The "green eye" is interesting, I have a number of copies of this booklet with green flaws of various sizes and positions, so I can say that a falw of this colour is not uncommon the position of it on your example is particularly effectve.

Barry,
Thanks for the response on this too.
Now at least I know that that type of flaw is not uncommon. As you say, it does look effective.
Like yourself I am very interested in booklets of G.B. (and the world) and am always interested in sharing information. I gave up on the last of our booklet collection (prestige booklets) a couple of years ago but have plenty of dupes of Machins and panes (including cylinder numbers etc)
Glad to see another active member
Regards
Ron

A late addendum to 1127
If the line IS vertical it cannot be a doctor blade flaw. The blade moves across the cylinder as that rotates. Lines caused by ink particles under blade will slope one way or the other. Difficult to determine on a single stamp but should be obvious on a large cook book pane

Robin,
Thanks for that info about the doctor blade flaw. Presumably the printing process is different on the booklet - I will have to delve into the pamphlets I have on the booklets.
Appreciate that update.
Ron.

Not at all!
However the layout of the primary sheet is different.

Doctor blades are always sloping, whatever the printing press or layout is.

Vertical flaws are something on the cylinder.(Horizontal flaws may also be the same, where the layout of the panes is sideways eg. p4 or 2+2)

Even the phosphor bands flaw which gives two very narrow bands slopes! This is because the phosphor cylinder was not held firmly in place - allowing the cylinder to move
