How to control density

Each frame of the SMPTE pattern for this device which is printed out by TEST PRINT consists of 16-step wedge, SMPTE pattern, and 1024-step gray scale. Measure the density of the 16-step wedge or SMPTE pattern and use it for the density control.

IMPORTANT

Use the SMPTE pattern for the density control.

Do not use the calibration sheet that is printed

with the CALIBRATION function on the mainte- nance menu for density control.

The calibration sheet is the sampling data for the automatic density correction.
