A pattern image for image gradation correction
Image gradation correction pattern is formed on the position away from ETB center to right and left in the following order.
ETB 1st round
1) Pattern image for adjustment of LED light intensity
Y, C, M pattern is printed on the left side only.
This pattern is to adjust the light intensity of the LED for the color displacement/image density sensor (left).
2) Pattern for timing reference
Bk pattern is printed on the same position at right and left.
This pattern is to measure the timing of step 3), 4) and 5).
3) ETB base
The machine measures the ETB base condition of the same position with the halftone patch that is measured at the 2nd round of ETB.
This is to measure the density of halftone patch accurately. The timing is determined with using the pattern printed at step 2).
ETB 2nd round
4) Pattern for density condition
Halftone patch of Bk, Y, C, M is printed on the left side only.
Measures the density condition of each color. The timing is determined with using the pattern printed at step 2).
5) Pattern for turn-on density detection
Halftone patch of Bk, Y, C, M is printed on the right side only.
This is to detect the turn-on density of each color (the printable minimum density). The timing is determined with using the pattern printed at step 2).
