Maria Barragan: ENGRAVING

FROM MAYA TO ILLUSTRATOR TO ENGRAVING

LASER CUT FILE

Danielle Aras - Laser Engraving to Printmaking

This is a second laser engraving I did on a 12x12" sheet of acrylic.

 Once again I used Illustrator to create the file. This time I used a deeper line for the outer lines of the buildings and a shallower line for the interior details. This is what the Illustrator file looked like:

I also ended up printing this plate. I chose to use it as an intaglio plate but would also like to print it as a relief in the future. This was my first experience printing an acrylic plate so there was a lot of trial and error and I would like to pull more prints to try to get more of the lines to fill in. This was printed on Rives BFK paper.

This is my initial laser engraving. It was done on a 16x20" sheet of acrylic.

 I created the file in Illustrator and used two different line depths as I was anticipating eventually pulling intaglio prints from the plate and wanted to create variation in line weight. Below is what the file I sent to the laser looked like.

The way that laser cutting or engraving is done is by assigning colors in certain file formats. This provides a different intensities causing for a lighter or darker lines on the surface of what ever material it may be.

I used my illustration also my logo. Then I entered it into Adobe Illustrator. To separate layers by  manipulating the layers and image trace setting. To make the lines coincide with the desired illusion of depth by using the lasers intensity levels. The red lines emit a shallow line. The green lines emit a higher intensity than the red so it would qualify as the mid-tone or medium value line. The yellow line emits the most intense line or value meaning it cuts the deepest in to the surface plane.

 

  I was instructed by the technician that are over the laser engraver. That the complexity of the illustration would cause the laser to take 5 to 6 hours to complete the task. So they advised me to use different values of black as a substitute for the value change that is done by the laser recognizing the differences. Not what I was hoping for but due to time restraints I followed there instructions.

Here is a better example of the separation of line and value. Concerning how lasers separate and define the intensity below.

 Here is the results through the process. You can see how the lines are defined differently with the addition to color separation.
