How to specify a colour to a printing company

Even if you do it doesn't give exact matching.

Not a solution to your dilemma, but this will highlight the difficulty of the task:

When I did that a couple of years ago I got a perfect score, I did take quite a while before I was happy to hit the "score" button though ...

[Richard]

I took a while, but only managed a score of 30 :(

[Fredxxx]

32 - I do wonder how much difference the quality of the screen makes.

[Fredxxx]

Right, did it again and got 0, this time spent some time rechecking and making full screen. Was convinced that there was a sequence of 3 colours on top row that were not smoothly changing.

[Tim Lamb]

I got 8. Best score for my age range is 2!

[Andy Burns]

That could be possible if your screen has only 6bpp, rather than 8bpp

[Mike Barnes]

8, after running out of patience - the errors being in a 7-wide clump # ####### in the blue-green area.

Can you not buy colour cards to stick next to your screen so you can adjust your monitor to be accurate? Every monitor I've seen you can change brightness, contrast, and R G and B individually, and often other stuff too.

[Davey]

I got 15, although I didn't spend a lot of time. I'm in the 60-65 age range. I'm using a laptop, which might not be the best.

You must have been going around with your eyes closed. Many, many monitors have no means for adjusting RGB at all - or only with a very simplistic preset profile. Getting monitors with properly, independently adjustable RGB used to raise the prices very substantially.

(Of course, the computer to which the monitor is attached might have various options for adjustments.)

[James Wilkinson]

I've not seen a CRT that can't either, but then I don't buy cheap shit.

[Richard]

No, you just talk it.

[James Wilkinson]

A CRT that won't do 90Hz was never purchased.

[Dave W]

Another factor is the ambient lighting when looking at cards, especially in these days of so many lamp types, and daylight conditions. Then there is the unknown spectral reflectivity of the cards.

I assume you are supposed to use a standard lamp of some kind? Anyway, = even without that I'm sure it would correct the monitor a hell of a lot.=

Errrrr, the people that made them must know that.

Paddy calls Easyjet to book a flight. The operator asks "How many people are flying with you?" Paddy replies "I don't know! It=E2=80=99s your flipping plane!"

[Vir Campestris]

The special monitors we have at work have a little arm with a sensor that checks the colour.

[James Wilkinson]

Surely once you've calibrated a monitor, it stays that way?

[RayL12]

Yes, Andy, that can't be stressed enough.

Print tests with a particular printer will get you somewhere near, should you be very concerned.

I once did a 4in * 3in advert for a young girl beautician. She was very satisfied with the overall looks and final print but, the outcome was so different from the screen 'and' my home print. This in spite of knowing and using the correct colour set for that issue.

Given all the hardware and software calculations and interpretations, putting your digital view to an unknown paper and getting the same image is unlikely.

Though, as in my one case, different was upsetting, it still looked well.
