Colour match issues indoors and out
We are printing signage for a local pub which is basically a diabond sign in a wooden frame, we where told to print c30 m20 y40 k10 as this would match the paint on the frame.
The signs are a good match indoors but when we took them out to fit them they are quite a bit different, so much so that the client has rejected them.
We are trying our hardest colour match but what ever looks good indoors changes as soon as we take it outside.
Has any body had this type of problem before and what did you do to overcome it.Many thanks
Russell.

yes it can be a pain
my guess is the colour you printed for the outdoors to be a greener shade.
we printed and laminated (important) the relevent part of the roland swatch and took it to the painwork. customer picked what he wanted.
mat satin brick work is not going to look the same as a laminated print, so you are up against it really -
Russell,
I also make use of a Pantone Bridge, because often a Pantone / RAL colour appears one way and the CMYK equivalent is a slightly different colour.
Also, the lamination is something that changes slightly the colour, even though it is ‘clear’, held up to the light it has a slightly yellow appearance.
As Chris said, the best fit ad that is all it will be is to print the colour swatch and laminate it with the laminate you plan to use. In that way, they can pick the best colour in natural light.

This is known as metamerism, where colours change when viewed in different light
sources. When I used to colour match screen inks, we had a cabinet with different
light bulbs to simulate different conditions, ie, daylight, incandescent light, fluorescent
light etc. With experience, you could usually work out what needed to be added to
the colour match to achieve your desired colour (we used a colour wheel method).Achieving the same thing with digital is more difficult, as you would have to print,
then tweak, then print, then tweak, and so on, so we usually print out a selection of
colours reasonably close to the requirement, and ask the client to pick one.Greys are notorious for metamerism unfortunately, and it is very difficult, if not
impossible to get them looking the same, or often even remotely close under different
light sources.
