Digital BW, The Print

HI guys I have a question. Suppose I put glop on the yellow position.

and print a yellow using image block (like those purge prints of individual colors)

I could technically .... get a borderless covering of Glop right?

R3000 can do front load borderless (I downloaded the driver to check if it works.)

Next Question is how does one control the amount of glop .

use a lighter shade of yellow image file ?

I am avoiding QTR since it does not cover the full area.

I thinking out loud and maybe the glop and uncover area may not be so obvious.

thanks for reading i have been asking many questions here so far. thanks for the help.

I am sort of trying to get a workflow as likely to work before comitting to a new printer.
