Hi

I have just bought an Epson R1800 and am struggling with the settings. I installed the printer profile that came with the software and now I am unsure if it automatically is being used. when I go to the advanced settings on the printer settings it tells me under color management that I am using "color controls" and my gamma is 1.8.

Now I am using windows and I thought my correct gamma was more likely to be around 2.2 and I believe this is the reading to which my monitor gamma is set. Should I change the gamma to 2.2?

I also wonder if I should change color management to ICM which I assume would allow it to use the profile sent with the printer.

I have already read the advice on setting print colour management with Epson pringers and Photoshop but my dialogues are different from those described and I am so new I really am not sure how to sort it out. Sorry if I am a bit slow here but I haven't really done this before so all advice gratefully received.

Yes, give that a try. This will allow you to utilize the profile but you need to make sure you setup the rest of the driver and Photoshop correctly (No Color Management in Print with Preview as an example). Epson should have a complete step by step set of instructions on their site.

The gamma setting of the display is independent of the gamma of working spaces or print spaces.

Thanks for the reply digitaldog.

I'm afraid I'm using Elements so I'm not too sure how to set it up. I have searched Epson's site but with no luck. I have seen quite a few articles on Photoshop settings which tell you what to do in a series of screenshots but without making a lot of sense to me and not referring to Elements.

Is the aim of the excercise to stop the printer having anything to do with colour management and to let Elements do it all or is it to stop Elements doing it and let the printer do it? I seem to have read that it is the former, but if so, what use is my printer profile?

Would I be correct in assuming that Elements wouldn''t require any settings to be done to it?

Also, if I am using the printer profile should I just chose ICM from the printer settings  color management dialogue box?

Lastly should I leave Gamma to sort itself?

Sorry to be so dense.

Hi Reggie,

Thanks very much for this extremely helpful link. I am pretty sure I know what I'm supposed to be doing now and I might even be tempted to buy QImage at the same time!

Thanks again,

Willie

Ive been printing on my R1800 from PSCS2 with "Let the printer determine colors" with fairly but not optimal results.
Lately Ive tried to figur out Color management along with the printing but get bad results.
THE PREVIUW GIVES A CORRECT PICTURE OF THE PRINTED IMAGE, but it is way of the actual image as shown in the main window in PS. The printed image is to light/bright and have a green cast. I am using the latest ICC-profiles for the printer.

My settings are:
Main window:
- Color management
- Document
- Let Photoshop determines color
-SPR1800 Premium Luster
-Perceptial/Relative colorimetric (Ive tried both) and black point compensation is on.

In the printer properties/advanced:
-ICM is used and "no color management" is off.
- all other settings here with best quality/paper etc is checked and doublechecked.

I just cant find anything wrong with these settings, they seem to be according to what is recommended around.
Anyone out there with similar problems or idees on how to solve this, I would be greatful.

I have sorted out some problems! When using color management it seems that the previuw window in the printer driver will not show the image correct. So I cant expect this to be looking simular to the printed image. Right?

The only problem now is that the printing is too dark. The colors are correct. I have calibrated my screen with eye-one so the screen should be correct. I am using a non-dedicated profile, which come along with the printer (Epson r1800)  and premium luster paper.

Is this unusuall? I mean that the profile is so out of "tuning" when it comes to brightness?

Hello,

To get the same brightness on paper as you see on screen, you need to illuminate your print to about the same brightness level. Try this for experiment: make a blank document in PS filled with white. Put a sheet of your paper near the screen. Compare the brightness of the two. You'll see that PS document is much whiter and brighter. Shine something onto the paper (like one of these variable strength lamps) and see how much more light you need to match the whites.

Hello,
Do you mean I should reduce the brightness on the screen to match that of the paper then?

In short - yes. Ideally, the brightness level of your screen should correspond to the viewing brightness of the finished print. But this is VERY difficult to achieve with LCDs (some are VERY bright). CRT monitors are much more apt at setting correct brightness.
The calibration package should be able to guide you in this. For example, Monaco EZColor allows you to choose the initial brightness level and then measures the white patch while you adjust brightness of your monitor. THEN it starts calibration process. Some packages even measure ambient light levels and adjust for changes in real time.

Allan

PS: Are you using SoftProof in PS to compare the printed image to? Do you switch on "Simulate paper white" (this will dim you preview considerably)?

I bought a printer (R800) just 2 days ago and I am struggeling with the same.
Only I am working in/from Aperture.

I Aperture you can find an whole  range of color-profiles wich are supposed to be good...
there is even a profile intergrated especially for the R800 printer.
When I choose this profile... it is like the light going out on my screen.. meaning that the picture becomes a whole lot darker... just the way it is printed indeed !

This means that I have to adjust the picture... make it brighter etc. to get a good result.

So I was thinking... I need to adjust every picture before I print it Huh??


Probably there is no other way but to buy a good calibration package  ??
