Matching physical colour to photoshop to printer

Say I have a particular shade of blue on a physcial piece of paper. I want to use this exact shade of blue in photoshop, and to have it be the exact same shade of blue as my sample when I print it.

How do I do this?

I have access to a laptop with built in pantone colour calibrator, if that helps. Not sure how I could use it to serve my purpose

The only way I could think of going about this is by somehow scanning the colour sample, finding the colour code and using that in photoshop. I'm not even sure if thats possible, its just an idea

Thanks in advance

Will

Good luck with that !. You are unlikely to get an exact match as you will be printing with different inks, to that used on the coloured paper, and on a different paper.

However to get close :

1. You need to measure the colour. I use an i1pro spectrophotometer with i1Share (as downloaded it does not run on 64-bit systems but by swapping the EyeOne.dll from the diagnostics app it will run).
If that kind of equipment is not available to you, then using a camera with some known colours such as a calibration chart or colour checker is your next best thing.

2. To view the colour on screen you need a calibrated and profiled monitor, which D.Fosse has covered above, - however you are now viewing a source that emits light instead of reflecting it - so it will not be exact.

3. You need to use the correct profile for your printer and paper combination. I do use profiles which I make myself - however as D.Fosse said, the manufacturer profiles are quite good these days particularly for paper sold by the printer manufacturer.

Even with all three in place it will depend on the actual colour. Not every colour can be reproduced in every colour space. So a colour that can be made with the RGB colours may not be possible when printed with CMYK inks.

So you can get close - but chasing exact will have you running in circles.

Hi

same shade of blue as my sample when I print it.

What kind of printing are you thinking about. Home printer, professional printer, what subtract will this be printed on, etc ???

With a spectrophotometer, such as the i1 Pro (not to be confused with the colorimeter i1 Display Pro), you can measure the color directly and output Lab numbers to feed into Photoshop.

For most practical purposes, however, a well calibrated and profiled display should give you a good screen to print match. This way you can just do it visually. But this means you can't just set your calibrator to some default "standard" numbers. You have to work a little to set the right parameters.

The trick is to pick your targets for white point color / luminance and black point / contrast range so that the screen matches the print, not the other way round. Monitor white should be a close visual match to paper white. This is a purely visual process that is heavily influenced by your working environment, so no set numbers can be given. Get the match visually, and let the numbers fall wherever they want.

All this assumes a reasonably good printer profile. Calibrating your printer is also possible, but usually not necessary. Most manufacturer profiles are good enough, at least if you use their own papers.

This requires a multi step color management system.

You need a device that can calibrate your monitor. This will create a monitor profile.
Then you need to calibrate the printer, with the paper you plan to print on. This will create a print profile. Every printer, and paper is different.
Finally you need something like an Xrite Passport to calibrate your camera, and the lighting conditions you are photographing in.

It takes all three of these to accurately reproduce color.
