1. Scanner Calibration
Place a blank piece of A3/DLT coated paper on the exposure glass.
For the correct scanning procedure, see "Common Procedure for Scanning Test Chart" in NICE Function (Pro C5200S/C5210S).
- Display the NICE main menu. (How to Activate NICE)
- Press "Scan: Calibration for FR" on the NICE main menu screen.
Calibration data will be stored in the SD card. Remove the blank piece of paper from the exposure glass.
- Calibration data will be stored in the SD card.
- Scanner calibration is required only once for multiple FR density adjustments performed on the same day on the same machine. However, if you want to change the calibration sheet, perform the scanner calibration again.
- Following paper types are not recommended: Colored paper, textured paper, cast coated paper (Adjustment precision may decrease).
2. Adjustment Procedure
- Press " Print: FR Adjust " on the NICE main menu screen.
75%/60% (75U/60L) and 30%/15% (30U/15L) halftone charts will be printed in CMYK (total of 8 sheets).
Use the paper trays for A3 or DLT. Print the halftone chart with the same paper used for step 3 in "1. Scanner Calibration".
- 75%/60% (75U/60L) and 30%/15% (30U/15L) halftone charts will be printed in CMYK (total of 8 sheets).
- This test chart can only be printed on A3 or DLT paper.
- 75%/60% (75U/60L) and 30%/15% (30U/15L) halftone charts will be printed in CMYK (total of 8 sheets).
Place the 75U/60L and 30U/15L charts of the affected color on the exposure glass and press "Scan: FR Adjustment" to scan these charts.
For the correct scanning procedure, see "Common Procedure for Scanning Test Chart" in NICE Function (Pro C5200S/C5210S).
- Press "Save SP to SD: FR" to copy the engine SP data onto the SD card.
SP data (SP2-152-xxx) will be saved as a csv file on the SD card. - Turn off the main power and remove the SD card from the service slot and insert the SD card into your PC.
- Start up the "Image View FR" and click "START".
- Select the machine type and paper size (A3 or DLT).
- Click "START" and select the tiff files (75/30U tiff files) requiring the adjustment and csv file (s/n_shading_before.csv) saved on the SD card in step 4.
- Wait until the calculation process completes.
- File "s/n_shading_after_75/60/30/15.csv" will be saved on the SD card, which contains the modified shading SP value.
- (S/N)_shading_after_75.csv: The adjustment result for 75% halftone chart.
- (S/N)_shading_after_60.csv: The adjustment result for 60% halftone chart.
- (S/N)_shading_after_30.csv: The adjustment result for 30% halftone chart.
- (S/N)_shading_after_15.csv: The adjustment result for 15% halftone chart.
- The original csv file will be renamed as "yyyymmdd_hhmm_s/n_shading_xbefore.csv".
- File "s/n_shading_after_75/60/30/15.csv" will be saved on the SD card, which contains the modified shading SP value.
- Remove the SD card from the PC, and then insert it into the service slot of the main machine.
- Turn on the main power and press "Upload SP to Machine: FR" on the NICE main menu screen.
The file "(S/N)_shading_after_60.csv" is uploaded to the machine. - Turn the machine power off/on for the modified SP values to take effect.
- Repeat the above steps until the desired results are obtained.
How to Retrieve the Original SP Value
If you need to retrieve the previous setting, do the procedure below.
- Select the " yyyymmdd_hhmm_s/n_shading_xbefore.csv " file you wish to retrieve the original SP value for.
- Delete "yymmdd_hhmm_" from the file name.
- Replace the portion "xbefore" with "origin" so that the file is renamed "(S/N)_shading_origin.csv".
- Remove the SD card from the PC, and then insert it into the service slot of the main machine.
- Display the NICE sub menu. (How to Activate NICE)
- Press "Load SP to Machine: FR".
- Press "Origin".
- Turn off/on the main power for the original SP value to take effect.
