Subject: Re: [Puptcrit] Strengthening mat board (shadow puppets)


A lot of very helpful suggestions here. Thanks very much. I get the 
list as a digest, so I'd like to respond all at once. I'll tell you 
what I've learned:

I just bought some, and will see how the laser cuts it. Different 
materials take the heat in different ways. Some vaporize, some melt, 
some catch fire, some are a mess. Leather won't cut with a laser of the 
wattage I have access to. besides, it stinks when you burn it - smells 
like burning hair.

I hope Larry will weigh in here...

Kydex seems pretty cool - and cheaper than lexan. I prefer transparent, 
however. Obviously, if you want it opaque, you simply spray-paint it.

I'm doing variations of traditional Javanese puppets. They bend a lot 
in performance, and have a lot of "play", which is required to get 
certain effects and movements.

I'd be curious about this technique.

There are two popular models - the Epilog and the Universal Versalaser. 
If you call these companies, they'll send you nice little laser cut 
swatches. These are are around $10,000. Price depends on size of the 
cutting bed and wattage and other attachments. There are cheaper models 
I've heard about - a Chinese model that sells for  $3000, but they 
don't have a USA distributor.

Shadow puppets take a lot of time, both to design and construct. And 
after you've worked with it a while, you'll want to improve it - find 
the right balance points via trial and error, etc... And they tend to 
break easily - particularly in the wayang style, where they get thrown 
around a lot. The tools determine the aesthetic as much as the artist's 
own vision; the chisel method of Indonesia allows for incredibly 
intricate designs and flowing, round motif patterns. But they take 
FOREVER to make if you don't have an Indonesian wayang sweatshop 
readily available. Stanley Knives and even xacto I find very limiting - 
you are constrained to straight lines when cutting tough material, and 
results are (comparatively) crude. which brings me to...

there can be a lot of work to clean up these scans and generate clean

image on the computer (using line art, not a paint program) then the 
file should be usable by the sign company as it is.
Please, if anyone follows through on the task of contacting a sign 
maker about laser cutting shadow puppets, post your findings here for 
us all to see."

Lasers revolutionize shadow puppetry design.  You can make a puppet out 
of anything you can draw. They can achieve finer detail than even 
handmade Javanese puppets, and make the cuts in minutes instead of 
hours and days. A Javanese style wayang with several hundred "holes" 
could be cut in well under an hour.

Mr. Dunfee gets it right when he says "there can be a lot of work to 
clean up these scans and generate clean lines for the laser to cut." 
Photoshop is used to get an image scanned and into the computer, and 
also to prep it as far as contrast and other variables, but you then 
need to bring it into a vector-based program like Illustrator. Using 
the "live trace" function you turn the raster image into a vector based 
image consisting of "paths". The lasers need a vector image.

But I am simplifying the process for the sake of discussion. You need 
to spend a LOT of time cleaning up your vector image. LiveTrace can 
only get  you so far - you need to spend time and learn Illustrator. 
But once you have a good design (and you need to prototype it as well) 
you can make multiple copies quickly.

I'll put up some photos of the stuff I'm working on soon. And I would 
be happy to work with people who want to create puppets for new 
productions.

Cheers,
DMCG
