If that is so then all colour management would be pointless. The profiling makes sure that, say, RGB(255,0,0) looks as intended on all the monitors that are profiled. Of course not only that colour but all colours on the targets.NO .... it is the monitor you calibrate and not the image .... so belive I can repeat the wiew of my image only with a monitor with LUT calibration EIZO , uploading my calibration file.

Thus on calibrated monitors/PCs the image looks absolutely equal. (I do appreciate, though, that there might be still minute differences.)

I think that no one in this thread said that it wouldn't work as well in CMYK. The only thing that has been said is that it is an unnecessary step to convert in CMYK. It does work (as you know).Quote:

If you and the printing shops use colour management in the right ways then the three prints should not be different. And as well if I print the same file with three different shops I have three different images again.

The result is not unknown as in the process of profiling all components of your system you have ascertained that the printer puts out exactly the colours you see on the monitor. Thus all corrections you make on your PC/monitor are printed in the same way on your paper.Of course the HW must do the JOB ..... but it is a slave not the commander.

And that is why you calibrate your system and then do your corrections on the PC/monitor.Checking wichh red I want to be reproduced is my problem and I want to control it.

I answer above. In printing you have to control 3 HWs.
- Camera
- Monitor & PC
- Printer
If you loose one of those steps above you cannot control the final result of the image.
If for all the above threads we all agree in the camera settings (sRGB because only if you have a 4000£ monitor it will be hard you could cover Profoto or other WS).
Well, I do use AdobeRGB in camera as it is the slightly bigger colour space and gives more leeway in post processing. Also JPG only gives 8 bit so some of the inherent dynamic of the camera is lost when using 8 bit files.I answer above. In printing you have to control 3 HWs.

Exactly. And if you have a colour managed system then it is taking care of that. You send your image in whatever colour space it is coded in and the colour management system takes care that it is interpreted by the printer in the right way.The problems is the step between the Monitor (PC) and the printer.

To do so I transform the image from RGB to CYMK and I print using the profile previosly prepared of the mixing of my printer/ink/paper (I use printfix with Spyder colourmeter).
And all we say is that the step of conversion from RGB to CMYK is not necessary when all components of the system are properly colour managed.To do so I transform the image from RGB to CYMK and I print using the profile previosly prepared of the mixing of my printer/ink/paper (I use printfix with Spyder colourmeter).

Yes, that sounds right.Before sending the image to the printer I select not to use the colour management of the printer itself.

In this case I have total correspondence between monitor and printed image. I still have some small problems when using BW inks with my Epson 2100 especially for medium grey (let's zone V)that is not as dense as in the monitor.
That sounds like a gamma mismatch to me. But BW can be tricky for any printer.In this case I have total correspondence between monitor and printed image.

This means that your colour management is not set up completely right.I did as suggested using RGB and the printer prints a different image from what shwon by the monitor.
Edit: Forgot to add: And this means that the output is not foreseeable when sending it to a print service, even if that service is using proper colour management.
As I said earlier, as long as it works for you it's fine. For the rest of us it works without a conversion to CMYK.

I could be right or wrong ..... but If I see one of my images in 3 different monitor I have three different images.
NO .... it is the monitor you calibrate and not the image .... so belive I can repeat the wiew of my image only with a monitor with LUT calibration EIZO , uploading my calibration file.
In all other cases not.
And as well if I print the same file with three different shops I have three different images again.

I could say none ....
If I leave part of the workflow to the hardware It will be the hardware image not the mine.
Of course the HW must do the JOB ..... but it is a slave not the commander. If my printer will choose a different nuance from the mine in my mind , why spending time on PS modifying Curves and levels for an unknown result. It's better print directly from the SD card.

Transforming bytes in drops is a mechanical problem and is the hardware job.
Checking wichh red I want to be reproduced is my problem and I want to control it.
I want to control the process otherwise it is not my image. And even in your case. When you print your images the results will be a mixing between your head and you printer. Not something born completely from you.
