Colour Management

The final matter that is very important is colour management. This is a very complicated subject but I will very briefly summarise my approach. I print using Print with Preview. I set Colour Handling to Let Photoshop Determine Colours, the profile to the correct one for the paper and the rendering intent is Relative Colorimetric. I also tick the Black Point Compensation box.

It is also vital to turn off colour management in the printer driver. For my Epson printer I have to press the Advanced button and then select Colour Management as ICM and tick the Off box. If the printer driver does any form of colour manipulation then it will undo the colour management done in Photoshop. In fact, doing colour management twice is worse than not doing it at all.

As I explained in the Paper section, it is very important to have a colour profile for each paper/ink combination. Many paper manufacturers have profiles available to download from their websites, but ideally you need a custom profile that is specific to these printers. You can have these made for around £20 but some paper manufacturers will do these for free. They supply you with a file that you print with all colour management turned off - they should give you full instructions. You then send the printouts back and they then scan this with their colourimeter and email you the profiles.
