Hi everyone,
I'm thinking about making punched cards. I could need some information about the
material used for
them. Precise information about tolerances, specifications, references to more
information, and so
on would be quite helpful.
Best wishes,
Philipp

Sure.. I'm thinking about making
custom printed punch cards for small profit.
Still missing are round corners and the right resp. nicely suited paper.
what about fan-fold paper tape?
I made a
"machine" that is able to fanfold paper tape. Yes, but.... currently only
something like a
proof of concept. It worked too unprecisely by far. It needs to be reconstructed using
precision
components instead of a mixture of pneumatics, a stepper motor, and handcrafted wooden
parts :-)

Oh... I did look around in the web. Found machines that print and fold and cut and even

beyond my
mechanical skills. I still have another idea for a folder. I'll try it when I find the
time to do so.
There seems to be one major problem with the usual fanfolding systems: They perforate! If
you
perforate the paper web it's easy. That's done for computer paper and forms.
I did not find any reference to endless folding machines that would do the job - except
the patent
mentioned.
My post was about punched cards. Next week I'll send out some enquiries to some paper
companies
around my part of the world.
The most interesting question is if there is reasonable need/interest for nicely printed
punch cards
througout the vintage computing/computer museum community. I'd want to run them
through a
letterpress. I'd need to do a run of at least 150000 cards. That's about the
minimum amount of paper
to buy for a reasonable price.

It used to be that by far the cheapest source of light stiff cardboard for
EAM purposes was to buy boxes of blank IBM cards, trim them to size, and
print what you wanted on them.

Phillipp, I'm sure you're aware that there are both ANSI and ISO
standards available for punched cards. Sadly, I don't have a copy of
the X3.11 standard, but if I did, I'd send it to you.
150,000 cards is what, 75 boxes? Heck, that's not that much. I
probably had at least 50 in my office at one point...

Perforations are optional on paper folding machines. Some will not
even do the perforation function, so another machine needs to be
called into duty.

Do you think you could do it cheaper than Cardmation? For a few
hundred dollars, a collector or museum could get more cards than they
will probably ever use.

Probably. Their price for blank cards isn't very high. But I don't know what they

dollars.
If I find the right or nearly right cardboard stuff, I'll do a calculation. I
won't take my labour
into account as it's all a hobby. I have to get paid the press. And the paper, of
course... And a
device for rounding the corners. All in all seems to sum up to approx EUR 3000.

I have done enough time in a print shop.
Paper folding machines can be a real handful, and thus one of the most
expensive parts of a printing operation. However, paper folding
machines pop up in the US surplus market a fair amount, as the
independent print shops are killed off. It might make sense to do the
folding operation yourself.

Pretty neat stuff, but an almost dead industry in the US. So much has

Somewhere in between is probably the answer. Shop around, get a
folding machine, then modify it to your needs.
Of course. You can get that service around the corner.
But here it'll cost you lots of money for reproduction and machine setup.
I want to print the cards on my Heidelberg windmill.
I would not be surprised if Cardamation farms out the printing. Or
even the whole card making process.

there was a place in St. Louis where a friend of mine worked, which has
the card stock, and the dies to make all the cards you wish. He uses a
large run he had made for making up ticket sets for another hobby he has.
the card stock he used is similar to the fixed part of an old style
credit card form, which you may recall is about the size and shape of a
Hollerith card, including the little part clipped on one corner.
He no longer works there, but the capability still exists. Note that
the input stock is a 12 to 24" wide roll about 8' in diameter, don't
recall how many thousand feet long. He was able to get a short run from
a scrap roll to make his cards, but most people would need to order a
lot of cards. Think maybe 3 or 4 full freight skids, maybe 40" x 40" x
40" or so by the time the whole roll is exhausted.

Yes, that was my idea as well.

Possible. The card making process seems to be
quite simple. Take the paper and cut it to cards.
Waht I currently have:
- Cutting machine
- Windmill press
- Some letterset stuff (lead) - not related to the cards
What I'm still missing on my way to making cards:
- Photopolymer plate flow (RIP with "film making machine", developing machine,
Nyloprint machine
(washing, drying, exposure))
- corner rounding machine
- Mechanical guide that allows steady cutting of the cards' missing corner
- The right paper.
The photopolymer thing can be done elsewhere for now. I'll pickup the equipment on
occasion.
A corner rounding machine would be great. Though there seemed to exist cards without
rounded corners.
Paper seems to be available. Don't know prices yet. The price is critical. If it's
more expensive
than 1-2 EUR cent per card the project is endangered.
Have a nice Sunday,
Philipp :-)

Well, yes, if you want to print stuff. It may not be worth it, since a
PDF will do fine at most print shops.
- corner rounding machine
Nice to have, but not actually needed. Most card equipments will work
fine with card with square corners.
- Mechanical guide that allows steady cutting of the

A properly shaped hunk of wood will do fine for a jig.

Ah? Remember where we are here. An USB stick is better than several tons of cards as well.
But who wants the stick?
I think its quite ok to use letterprint to print cards. The original cards seem to be made
on a flexo rotation machine though. I suspect that with regard to the poor printing
quality. And flexo is very cheap....
The print shops accept pdf today, yes. They
make an offset plate and then print the stuff. But that's not what I want. I want
plates for my letterpress. So I must have some decent machinery for that task - or pay ???
for the plates made from pdf.
That's good news!!! Really!
That's the kind of tool
I had in mind ;)
I have found references to card stock on websites of local (means
German) paper distributors and paper mills. I have to see if someone has that stuff on
stock. If not, I'd have to deal with paper mill minimum order quantities of 40 tons or
something alike - which would be sad...
I know that.... Very well.
Kind regards,

Heavily used paperback books (K&R) will last a lot longer with rounded

There are absolute crap devices for hobby crafts. But they should be
adequate to make a few cards to test.
You used to be able to get a little "office" corner rounder for ~$100,
that can handle less than 1/2" thick pile at a time. The plastic top
work surface on some of them doesn't hold up well, and needs replacement
in less than 20 years.
http://shop.ebay.com/i.html?_nkw=corner%20rounder&_fln=1&_ipg=200&a…
On eBay, they start around $75, and real printshop ones cost MONEY.
Yes. Definitely a task for a home made jig, or
modified parts from a
cheap table saw.
Cheapest source still seems to be buying boxes of blank IBM cards.
Apparently some people stocked up too heavily 30+ years ago, and there are
still some colleges, etc. using them as blank stock for printing "add
cards", etc. I had a good local source 10 years ago, but he's gone.
It's pretty much the same as when a friend wanted the absolute cheapest
source of 1 by planks to make a bookcase. The cheapest source was "buy a
used bookcase and break it apart".

Remember embossed printing?
The new stuff is not the same experience. It doesn't smell the same,

There is a very active mailing list for folks interested in printing at
letpress at listserv.unb.ca (LISTSERV software, send a SIGNON LETPRESS message

Letterpress machines are still around, sometimes
standing next to the
latest and greatest "Speedmaster" machines. They're used for <don't

The term in English is "diecutting".
