Here are more details on what they are talking about:
The print controller on the Xerox (be it Fiery, Creo or Xerox FreeFlow) sends 600x600dpi at 8 bits per pixel to the print engine, therefore the process is NOT truly a 2400dpi process.
• The print engine uses VCSEL technology which stands for Vertical Cavity Surface Emitting Laser, meaning that 32 beams of laser light are used to create the image using 8 micron sized toner particles.
• The print engine takes the instructions from the print controller for one dot, and divides it into 16 quadrants. For example, in an area that is supposed to show 25% cyan, rather than dimming the laser to create the needed fill in the pixel, the Xerox VCSEL engine places a pattern in the 16 quadrants to simulate the 25% fill using a screening method.
In summary, each 8 bit 600dpi pixel byte sent by the computer through the RIP print controller is converted in the Fuji-made engine to 1 bit 2400dpi binary pixels.
- This may be a bit outdated, I am curious who might have more infomation on this subject. Go ahead and help us understand the math!
