I print from Photoshop to a Canon Pro-100 printer and whilst there has always been a small amount of variance between the colours shown on my screen and those that appear on the prints just a few days ago I had a major matching problem.
The red was showing as a russet brown and other colours in similar deteriation of actual colour. I have been on to Canon and they say there could have been a problem with an update.
Now my screen is in sRGB but photoshop does not have that option on it's print profiles. I printed all the options and decided that the best one wasl PAL/SCEM.
But is this correct - what would anyone recommend to match with a sRGB image etc, How do you do calibration between your screen and printer?
Thanks

Hi Dorothy,
As you're seeing a difference in color, you may have a look at this article and see if it provides helpful information: https://helpx.adobe.com/in/photoshop/using/printing-color-management-photoshop1.html
Also, you should try changing the screen color profile to sRGB IEC61966-2.1 for both Windows & macOS: https://www.lightroomqueen.com/how-do-i-change-my-monitor-profile-to-check-whether-its-corrupted/

Hi Dorothy
You have picked this up incorrectly, unfortunately you are not alone, many do 🙂
Colour management is fairly simple to operate. The monitor profile has to describe your monitor and the printer profile has to describe your printer, ink and paper combination. Picking profiles at random is a recipe for colour issues.
The best way to get a profile that describes your particular monitor is to use a hardware calibration device. For printer profiles, they can be produced, given the right equipment, but most paper manufacturers have downloadable profiles that work well.
The explanation below may help your understanding:
Colour Management simple explanation
Digital images are made up of numbers. In RGB mode, each pixel has a number representing Red, a number representing Green and a Number representing Blue. The problem comes in that different devices can be sent those same numbers but will show different colours. To see a demonstration of this, walk into your local T.V. shop and look at the different coloured pictures – all from the same material.
To ensure the output device is showing the correct colours then a colour management system needs to know two things.
1. What colours do the numbers in the document represent?
This is the job of the document profile which describes the exact colour to be shown when Red=255 and what colour of white is meant when Red=255, Green = 255 and Blue =255. It also describes how the intermediate values move from 0 through to 255 – known as the tone response curve (or sometimes “gamma”).
Examples of colour spaces are (Adobe RGB1998, sRGB IEC61966-2.1)
With the information from the document profile, the colour management system knows what colour is actually represented by the pixel values in the document.
So what can go wrong :
Colour management is simple to use provided the document profile is correct, always save or export with an embedded profile, and the monitor/printer profile is correct. All the math is done in the background.
I hope that helps

Just for clarity, based on your last reply, are you using e-SRGB as your monitor profile ? e-sRGB is an extended gamut colour space. It is not a monitor profile and should not be used as such. The monitor profile has to describe your monitor for colour management to work correctly.

e-sRGB is a horrible beast that should be avoided at all costs. It is a very early, very crude and primitive attempt at a wide gamut profile, by now completely obsolete. It gets the wide gamut by clipping the black point beyond recognition, and probably the white point as well.
In short, it will butcher your files. Don't use it.
Read Dave's post again, carefully. A monitor profile has to describe the monitor's actual and current behavior. In the same way, the print profile has to be the one corresponding to the actual paper / ink / printer used. You don't "experiment" with profiles - you use the correct one.
The document profile and the monitor profile and the printer profile - they are all describing their own repsective color spaces. A profile is a description of a color space, a map if you will. They are not supposed to "match", they emphatically should not be the same. They just need to be correct for the color space they correspond to.
You really need to stop what you're doing and go back to start. As Dave says, this isn't difficult. Most of it works out of the box if you just let it.
