Title: Paint, how does it work?
Post by: YGT on May 24, 2006, 09:39 PM

I went to my local paineters today with a set of GT fork standers in a blue colour i wanted.
anyway they didnt have that colour and it wasnt in the RAL books or the other one.

I was told they would need to send it off ofr analisis and it would cost a fair bit.

When this is done, does it come back with a universal colour number / code or is it different from one paint lab to the next?

Thanks

Mark

i took my pk to the painters and left it there whislt they matched the paint
as superbike dan made it up in enamel
they did a perfect match for 15 quid
carrs paints they called .any decent paint shop can colour match
as i did it for 18 months and it was piss easy

thanks,
but does anyone else know how colours are made and if there is a universel colour code used to identify shades?

pantone is another popular colour range ( if range is the right word)

 thats what we use at my work, they have a massive book with thousands of shades of all colours, only problem is that you might have trouble findin someone who mixes pantones in a cellulose. we use a place in london but thats no good for you i guess..

good luck ;)

the paint is digitaly read throu a computer and its parts are downloaded as a written list .they take a photo type thing
and from that the computer program can work out proper match even allowing for sun fade it is spot on.most car body shops use this technic or they use colour chips.

send it off for analysis? crap

the paint shop where i go to has a massive colour chart, and the right colour (or so near that normal eyes cant tell the difference) will be in there.

if they are charging you for this "analysis", tell them knackers

also note that the shade of primer used can alter the shade of the topcoat to a small extent

we get tons of aluminium extrusions and pressings powder coated in work, often getting items powder coated in the same Ral colour, but from a different batch of powder, or from a different powder coating plant and the difference can be like day and night sometimes, even with "the same" Ral colour. that's quality control and upper and lower limits for ya, i guess...

we used to get a colour very close to it and tint it to match
which most good paint shops should be able to do
