Re: [Digital BW] 16 bit greyscale / Ultrachrome / QTR

Actually you are wrong.

The data sent to the printer head is not eight bits.  It is only one
bit.  It tells the printer to print a dot or not print a dot.  Some
RIPs that send this data to the print head do indeed use 12 bits
internally.  In some printers you can choose from three dot sizes
which requires 2 bits.

Please know the facts, before posting.

Thank you,
