Papy24, wrote this on another thread:


Quote:
Now printing cylinders are engraved by a diamond needle directed by computer.
Now, engraving is flat, without thickness. It's a pity.



When I read this I realized we hadn't discussed here the effects
that computers have had on the art of engraving.

Do we still need engravers?

Here is a pic I borrowed from one of Kirk's posts.



Jorge Peral sits at the computer engraving the $10 whale stamp.
No soft steel die or burin anywhere in sight.
No engraving the image in reverse.

Here are the results.

Canada Scott 2405 2010



They were issued in panes of 2



Not a bad looking stamp but nothing special about
the engraving.
How much credit to Jorge and how much to the computer?

Thanks BC.
The only copy I have is this used one on cover.
I asked the recipient in Austria to send it back to me but
I wish I hadn't also included those 34 year old
stamps which kind of screws it up as far as Postal History
goes.
But the stamps did their job and the letter actually
flew over the big pond twice.

Lithograving: You ask whether hand engravers are still required. Absolutely, but the problem is, will there be anyone capable of doing the work in the coming years, and will companies be willing to use these expensive craftsmen.

In 1991 De La Rue employed 15 of the 50/60 capable banknote engravers worldwide. This compares with the year 1817 when there were 10,000 engravers in Britain alone who were capable of engraving a Bank of England bank note. So it is not just stamps that are suffering from a lack of hand-engraved work.

Computerised engraving is "OK", but the output lacks the subtle depths achievable when using burin on steel. If computers can eventually perfect that aspect, then the craftsman will no longer have a place in the process, I fear. GLENN

Hello,

I can show you those stamps :







They are printed in TD6, (intaglio 6 colors) and it seems to me that is in offset/litho.

I don't like.

TD 6 = 3 direct plus 3 indirect recess whereas each 3 comes from ONE plate using the Lambert-Giori-process. No offset-litho involved...

Sorry, I badly explain. I know very well that is TD6 printing 3 + 3 colors, but it is the Chambon process.
I know it is not offset/litho printing, but for me it seems like offset/litho.

Yes,those French ones do look flat, dull, nothing outstanding,
just a lot of colour.

Phila@post might as well have printed them offset, would have been cheaper and looked the same.

Its not the computer, it is the people writing the software that traslates what the designer istrying to design and controls the engraving.

The French stamps are particilarly disappointing, given the beauty of past French issues. From the Post Office's point of view, I accept that these are simply labels, but wouldn't they be relatively easy to fake for purposes of postal forgery?

Hello,

You are right all.

It seems that Phil@poste would be able to buy a new engraving system with a new software to obtain an engraving like before with the transfer roll, and only with a numeric picture of the die, or why not a numeric drawing.
Engravers can to be worried.

Since they are engraved they would still be harder or near
impossible for these modern forgers to reproduce.
They usually fake the most common definitives
such as the Machins and here in Canada P(ermanent) stamps
which can be used indefinitely and makes it very financially
attractive for these crooks.

Some are so good that even a collector would have
difficulty in telling the fake from the genuine.
So how would the general public or a postal clerk or
a letter carrier know the difference, or care ?


Forgeries to defraud the post office are nowadays nearly
always printed via offset/litho by these gangs who produce
tens of thousands of these fakes.
But I'm sure it would be quite easy for someone
to run off a few thousand on a plain inkjet or laser printer
