A recently discovered dry printing error on the 21/2d. Bright Blue S.G. 460 is shown together with a similar block of four with the ghostly Control A36 Cylinder 2 No Dot printing.
This particular Control is known for its very faint appearance on the printed sheet. The discovery confirms that two states of the Control exist. Unusual and Unlisted.

Is the faint Control A36 Cylinder 2 No Dot a characteristic for dry printing?

hi! asmodeus. yes to your question. The appearance of a dry printing from this cylinder has proved that it can happen. It is possible that there are various values from the photogravure printings with color omissions yet to be discovered?. Who knows?.

An update on this possibly unique dry printing which I sent to Hugh Jeffries for possible inclusion in the Specialised Four Kings catalogue has been returned and is a likely candidate to be included in the 2009 edition as a missing color catogory under King Edward VIII issues. Hugh is also using a scan of the item for an article in the Stanley Gibbons Stamp Magazine Monthly at some point.

Following Ron's response, here is a scan of the piece showing a progressive dry print that I have. In my KGVI Coronation collection I have dry prints, that are perfect - clean gum on the reverse, but dry prints resulting from off-sets. In this ha'penny exapmle the gum is perfectly clean, and so is a real dry print.

The second stamp along at the top has a delightful flaw of a hair growing out from the nape. I looked at the (only) three sheets I have of this value, but failed to find it. As it seems to be black ink and not green, I suspect it is a one off accidental. But if anybody has noted it already, please let me know.

I've scanned at 400dpi, but if it isn't fine enough, please let me know and I'll go up to 600. On my screen the flaw shows up well enough when zoomed in on.

Best wishes, Robin

Hi Robin ,
Do you have an actual description of 'dry print'?

To me, It implies that there was insufficient ink to make a full impression, but there is no actual definition listed in my edition of the 4 Kings catalogue, though Offsets and Double Prints are described.

That is an impressive piece shown in your scan and a very interesting addition to the collection.

I will check on the stamps I have to see if I have anything like that flaw on the nape but it would seem like one of those 'one off' foreign matter jobs.

I presume you have studied it closely enough to eliminate the possiblity of someone accidently marking it with pen? I mention this as you said it was black ink and not green. (No doubt Grandmothers and eggs might come to mind here )

I sometimes find that 'black light' shows some flaws up in a different light too.

Regarding the scans, so far as I am concerned you do not need to go that high. The scans we have on our website are usually 75-100 dpi and if we want to show close up varieties we find 200 is plenty. The 400 took a very long
time for me to download on the magnified image but that is because we are on dial-up and not broadband.
(Old fashioned we are)

Thanks for the postings and let's hope there are more 'lurkers' out there prepared to join in on the list.

Regards
Ron.

Hi Ron,

Actually the definition of dry print is an image printed with an ink with low moisture content. It is a definite and deliberate technique used in printing stamps (and other things) that reduces shrinkage and gives a cleaner, sharper image. But in our specific context, it has to mean simply that the ink used on that particular roller and cylinder was literally drying out, and presumably running low in the reservoir!

Offsets are presumably the exact opposite when presumably there was too much moisture in the ink - possibly the reservoir had been filled slightly too full? - and the impression was transferred to the next sheet that was laid on top before the inking had dried.

But there is another kind of offset - when the gum is moistened for some reason, and pulls a layer of ink off the sheet it is laid upon.
I wonder what the difference is in a philatelic sense? I mean, is one "genuine" and the other an accident? And how can one tell the difference? An expert opinion here would be useful.

As for lurkers, the list of people signed in for the Discussion Boards is surely much shorter than total GBPS membership, but as awareness grows there should be more participation! Let's hope so.
Cheers, Robin

Hi Robin,

Thanks for that information on dry prints (and offsets to boot) - that's clarified it for me very well.


I had put a thread on the QEII category regarding 'ink bleed' on the 2p Machin (no feedbanck on that) and perhaps that was caused by too much ink.
If that is so then presumably the printing would have been from the left, across the sheet.
Does that make sense?

Re lurkers, I am not sure when the list started but the earliest post I can find was in September 2007 and I must admit I am surprised at how quiet the list is.
It does seem to have improved over the last couple of months.
I wonder just what percentage of the GBPS membership has internet access, or indeed, a computer.

Keep up the good work and the postings.
Regards.
Ron.
