Re: bizhub c384e color question
HAPPY NEW & PROSPEROUS NEW YEAR TO ALL
I think customer is very unreasonable, he is using entry level machine without Fiery(Fiery- which have capability of better calibration using densitometer OR spectrometer). Even high end production machines will not match screen colours 100% with hard output due to gamut difference in additive and subtractive colors.
Either he do not know ANYTHING about colors OR he is very experience in printing technology and just trying to get maximum at low investment.
You may try following -
1. Try to explain him above difference (this is difficult task, I know)
Secondly on A3 sheet put 5 bars for each color ( CMYK Each 5) & fill with 20% to 100%(5 steps). Ask customer according to him which shade do not match to his design and try to adjust only that segment After calibration( Highlights, Mid tone & Shadows).
You can use to compare the output with standard CMYK color reference charts for different color mixing. Which should match close to 90%
If you adjust as above do not perform Initialise+Stabilisation, in case if you have to, then restore the values back after calibration.
2. Ask customer to change color profiles from application software and show him that colors on screen changes as you use different profiles in application software (Adobe OR Corel etc.) if you put color management OFF colors looks very different on screen BUT if you check the % of colors in the file % are same. So WYSIWYG is actually not applicable in such cases.
Also please note that different versions of Windows gives color variations for the same file printed on same machine with same application software & setting. ( I was very surprised to see that but its true)
3. Now let customer play the ball, ask him to give you color profile which he has made for his own use. If he doesnt have ask him to get the help of professional color specialist who can make profile and also calibrate his monitor. Calibrating of monitor is very a special task, which needs very special equipment & should be performed under very special light source so do not promise him to help. Let him manage that on his own. These professionals charges are very heavy.
4. If he manage to give you profile file you can download that profile using download manager to machine and application software can use that profile
THIS WILL BRING THE COLORS CLOSE TO SCREEN.
Hope this helps
