Re: [Digital BW] Automating Spectro Measurements

2003-07-09 by Ernst Dinkla

Scott,

It looks nice and getting an old HPGL plotter for conversion sure
is the easiest way to do it.

I've made a somewhat longer guide ruler (about a foot usable
length) than the one that came with the Spectrocam and put it on
a board so the target paper can be shifted per row between the
ruler and the board. An extra sheet of polyester foil attached to
the ruler protects the target print from abrasion by the
Spectrocam movement. By printing samples of about 1 cm square the
hit rate becomes a lot higher and the ruler + the smooth gliding
on the foil removes the jerkiness of my movements a lot. There's
no foil between the sensor and the target of course. Not a "high
tech" as your setup but it helps a lot.

For the non DIY people: drinking a glass of wine helps too to get
a smoother movement but I don't make a habit of it :-) You have
to fill your glass of course.

Ernst
