A prominent company had developed a way to use a laser to directly image resist on copper-clad fiberglass. The process would allow the image of a printed-circuit board's outer layer to be adjusted to fit any distortion that had occurred during the manufacturing process. But in order to succeed, the image that contained thousands or even millions of geometric features would need to be quickly processed by software to produce a signal to turn the laser on and off during imaging. GCA produced the robust high-resolution raster software that allowed this company to present its first successful prototype.
