Question: When the store mix the paint.
 
http://www.acecalumet.com/images/paint-mix2.jpg http://images.asia.ru/img/alibaba/ph...aint_Mixer.jpg



I went today to buy my paint, When the guy was mixing paint..

does 100% of the paint color dye (or whatever you call it), have to make it into the bucket? (if youre getting a color)

i picked a color off the colors from the wall at my local store, but i saw a few drops of the color die, missed and landed on the top of the 5gal bucket..

He said it will be fine..

Will this be a problem, if i try to order more of the same color?
or am i just worrying too much?

A couple of drops out of a fiver should not be a big deal.

It might not even be out of your formula. I have that exact tint machine and probably the same tints from the look of it. The thing loves to leak a few extra drops after you are done tinting.

Possibly not too off-topic, as it may be pertinent, but are the tint amounts computer controlled on that bad boy?

It's a couple of drops out of each colorant that's added, not the five gallons.
If the machine is designed right, the minimum amount of any colorant should be >>a few drops.

Or maybe he's hoping you're colorblind.

Could you please explain that statement?

Suppose I want a quart of a paint colour called "White Dove" that requires a half drop of Yellow Oxide be added to a quart of white tint base.

Then what?

Do I end up with a colour called "Aged Newspaper" instead of "White Dove" cuz the machine added a few extra drops?

I've never worked in a paint store, but I'll sure try to explain my opinion.

If a few drops of color will be lost due to normal workday stuff happening, then the amounts of each color to be added should be considerably more than a few drops, otherwise the color would vary from day to day and depending on which person does the mixing.

This kind of manufacturing "slop" needs to be swamped out somehow, to get consistency.

It's kind of like you put in a vanity and the gap with the wall varies 1/2" or so over the depth of the vanity. If you can put in a filler strip 2 or 3" wide or more, this variation will never be noticed.

If it's only one gallon of paint, the amount of colorant is less than for five gallons, but the proportion between the colorants stay the same.
It's the colorant proportions that are at risk when the operator spills one of the colorants.
If he spills all the colorants equally, then I guess the resulting color would not be as intense as desired; the finished mixture color would tend toward the base color (white?).

I need to take a course in writing, I think. . .

No. That looks like a 5G shaker, two stacked gallon shakers and a manual tint machine. Personally we never bothered to sink the $12000 into the auto tinter we were offered when we took Pratt and Lambert as out main line. A store the next town over got the auto tinter and they've had more problems with it mistinting than I've ever had manual tinting.

And yes it is true that a few drops can make all the difference in a small quantity on lighter colors. Even if it were a quart and a dark color I wouldn't be too worried thought. It can take more tint than you might think to change some colors enough for the human eye to notice.

My old Duron tint machine, which is like the one in the photo leaks tint all the time and we've never had any color issues caused by it. The teflon cylinders in it just don't seal as well as they use to. My new P&L machine has tip caps that close after every tint is dispersed so it never leaks. Never dries in the tips either like the old machine does. I've had too many days of using Krud Kutter and paper clips to clean out the tips on the old one. :censored:

Oooooohhh....Tinters....!
 
I should post some pix of our Paint set-up!!

Since we're a C2 retailer, we were pretty-much required to have a top-line tinter for it.
They give you a choice...$spendy...$$spendier,...and...$$$oooffda! !!

The one we got is a $20,000 :eek: COROB (with computer, etc.)...JUST FOR C2.
* 16 colorant cannisters...each holds 6 Qts.
* C2 uses a 16-colorant system.
* This thing uses two transmissions, one one each side, running 16 gear-driven pumps.

We HAD 2 other auto-tinters (revolving platter style) by Fluid Management, but one bit the dust when an electrician overheated the circuit-board accidentally!
Soooo...now we're down to the old-fashioned "manual" :( tinter, 1 Fluid-Man. auto-tinter, and the big COROB.

It's kinda cool...sometimes we'd have all 3 auto-tinters shooting colorant at the same time...and just stand there and watch:whistling2:!!
(3 computers controlling 3 tinters...)

Thats pretty sweet. Back inthe day the mixer wasn't enclosed. If you didn't put the lid on tight it could be a big mess.

Corob Tinter
 
Hi , I work with a Corob Tinter and would like to know how the Formula quantities relate to the Measurements "Y" "Shot" and "1/4" as seen on colour matching equipment

Any ideas ?

Isn't this (dropping a drop here and there) why they dry you a little spot of test paint?

I have certainly had a can of paint that was tinted by machine, but when the color dried it was not even in the right ballpark (ok, maybe the right ballpark...it was still green...) but it was definitely off from the color chip. They offered to mark the mis-tinted can down 50%.

The nice part was, I didn't really give a crap about whether it was 'Mossy Oregon Green' or 'Fern Dream'. For this particular project (painting my compost bin) green was green.
