The HP7570A

The HP 7570A

I bought a Hewlett-Packard Model 7570A DraftPro 8 Pen Plotter in 1988, for over $5000.00!,       and used it to create architectural drawings, with AutoCad. Over time I moved on, the plotter got   stored away, used occasionally for random plots but as software and hardware developed, the       plotter did not, and in the end, I decided to either junk it, or sell it!

I got lucky, Paul Meillon bought it for $75, and he paid the $60 to ship it from Calgary to Montreal. The plotter left my home to Paul’s, and he is producing new work, new art. I am amazed at what Paul is getting from a machine designed to draw lines on paper and more amazing perhaps, it only took people in four countries to get it done, our global community indeed!

Paul’s Story:

“My name is Paul Meillon, I am an artist, scientist and inventor from Montreal. I am fascinated      by pointillism, how the brain blends points from a distance to create an infinite variety of colors      and even textures. One problem with this technique is the amount of time it takes to make a        painting, which can take up to a year! So I started brainstorming mechanical techniques to do      the same thing. Some hackers and artists from Columbia University were using old plotters          (pen-based printers) from the 1980s to create all sorts of art projects, including plotters that respond to music. Using their software libraries as a starting point, I hired some programmers in Hungary, Cambodia and the USA to develop code to make the plotter work, and be able to parse an image into dots, called stippling.

Stippling is an old engraving technique which creates varying degrees of solidity or shading by using small dots. As the software was being written, I endeavoured to transform a plotter that uses felt markers, to one that could use paint. At first I developed a high pressure system using a compressor and espresso machine, which exploded several times, sending paint over the walls and ceiling of my kitchen/studio. I finally settled for acrylic paint markers, the kind graffiti artists use to tag lamp posts and other public spaces. The results of my first “paint plots” were well beyond my expectations, it was great to bring pointillism, a 19th century craft, in the realm of the 21st century. Currently I am using the four printing colors (CMYK), and I am now trying to find a way to expand my palette.”
