Converting a Stencil Drawn in AutoCAD to BMP for InkjettingJanuary 10, 2016
In this short video a designer has drawn a sheet of small stencils. As usual, the designer draws the regions to etch away. The rasterization program has to invert the data to place the droplets everywhere except where the drawn geometries are located.
We show the data conversion from AutoCAD DXF file format to Gerber -- then from Gerber into the BMP file that is loaded into the inkjet machine. 05:15 mm:ss
Compensating for Droplet DiameterJanuary 11, 2016
When using an inkjet to create a mask for etching a stencil, it is important to compensate for the diameter of the droplet. Failure to do so will result in line widths that are wider and gaps that are narrower than designed. We show how Artwork's rasterizer supports droplet compensation.
In this case we are actually inverting the bitmap so the droplet compensation is reversed - we want to insure that the openings in the stencil are not smaller than intended. 04:11 mm:ss
