Printing Density Control System
RYOBI PDS/ RYOBI PDS-E/ RYOBI PDS-E AUTO/ RYOBI PDS-E Spectro/ RYOBI PDS-E Spectro AUTO/ RYOBI PDS-E SpectroDrive
RYOBI's printing density control systems calculate the difference in solid
density and screen density(the RYOBI PDS-E and PDS-E AUTO calculate only the difference in solid
density)between the color bar on the printed sheet and the OK sheet. This data is fed back to the
printing control system to control the ink fountain keys. Quality control which depended on the operator's
experience and skill can be performed numerically for faster, more accurate color correction,
eliminating the wasted paper and standardizing printing quality.
