SUBJECTS THE P&L MACHINE SYSTEM OP CALIBRATED COLORS
The P&L Machine System of Calibrated Colors was adopted at the September 2-3, 1959 Managers Meeting after six months of intensive laboratory work* The system-consists of ten colorants and the same light and deep bases that are part of the P&L Tube System.
COLORANTS
The P&L Machine System Colorants are not the same as P&L Tube System Colorants even though a few colorants in both systems contain the same pigments and are supplied at the same strengths. The colorants in; the two systems differ in vehicle composition and in consistency. The table below lists the P&L Machine System Colorants and certain basic data relative to composition,^strength, and exterior suitability.

All P&L Machine System Colorants are free from lead pigments and are legally "safe* (i.e. they contain less'than 1$ lead as metal, based on total non-volatile). All pigments are alkali-resistant.
The number of colorants was established by trial and error testing.
Ten colorants are the fewest that will provide good decorative colors In all color families. Many competing systems consist of 12 colorants; one or two consist of 9 colorants. The 12-colorant systems usually include a few that are made from lead pigments. The 9-colorant systems do not provide full coverage in all color families.
Except for Colorants A, C and K, P&L Machine System Colorants are considerably stronger than the related P&L Tube Colorants. The added strength expands the color possibilities of the Machine System as compared with the Tube System. Colorants F and H contain pigments

that are not In any P&L Tube System Colorants, Colorant P provides the means for making new lightfast exterior reds. In conjunction with Colorant K, it also provides the means for making colors in the violet family, a family that is represented by only one Tube System Calibrated Color, namely Iris 1106, Colorant G is 1,5 times stronger than P&L Tube Colorant 63A and contains ah entirely different pigment. Colorant'G utilizes a hew organic orange, 63A is made from Molybdate Orange, a lead pigment. Heretofore flesh and peach colors have been obtainable only by using lead chromate or lead molybdate
as tinting pigments. The development of a successful lead-free orange colorant was one of the major technical problems that had to be solved before the P&L Machine System was ready for launching.
The vehicle in P&L Machine System Colorants is a chemically treated oil to which wetting and emulsifying agents have been added to gain miscibility with emulsion paint bases. They are equally miscible with all other P&L Bases, The colorants contain no water.
All P&L Machine System Colorants are supplied at medium consistency (about the same as that of New Lyt-all Plowing Plat), They are thinner than P&L Tube System Colorants, They pour easily and work well in the machine ejection Valve, They do not skin in full or' partly-full closed containers. They do not thicken under normal conditions of use.
USE OF COLORANT IN MACHINE *
Before a can of colorant Is opened and poured into the Fischer
Paint Colorant Dispenser, it should be mixed for five minutes on
a paint shaker machine. After the colorant is in the machine, it
should be mixed for 15 minutes, -It should also be mixed not less
than 20 minutes each day, preferably in the early morning. Daily
mixing will prevent the colorant from "layering out* and will reduce
the possibility of faulty, bolor matches from this cause, P&L Machine
System Colorants may separate into layers on prolonged standing,
like virtually every other paint,
*
A machine valve may occasionally clog (for mechanical reasons or because of some accidental contamination of colorant) and deliver less than the required amount of colorant, A malfunctioning valve can be recognized by the way it delivers colorant. Normally, the
colorant flows out evenly and in a straight stream'. If the valve is Clogged, the colorant may spurt or the stream may be angled, When this happens, the valve should be immediately cleaned with a pipe cleaner wet with a little P&L Duosol,
Colorant should never be thinned or tampered with in any way. The addition of anything, other than more of the same colorant, will alter a colorant*s ability to produce matches for the standard Calibrated Colors,

COLORANT LIMITATIONS
Colorant additions may be made in I/I4.8 fluid ounce increments up to a maximum of 9 fluid ounces per 120 fluid ounce of base paint (the latter ratio is equivalent to 2 12/48 fluid ounces per 30 fluid ounces of base paint). The upper limit of 9 fluid ounces per 120 fluid ounces of base paint is the same as the one that
applies to the P&L Tube System. It restricts our ability to produce a few potentially Interesting colors. It is necessary, because the additon of more than 9 fluid ounces of colorant may alter gloss, drying, or some other quality of the base paint to which it is added.
Colorants, other than C and G, are suitable for exterior applications, but not every combination of these Colorants and Bases makes color permanent exterior paint. Very delicate tints may fade outdoors, not because the colored pigment is Impermanent by itself, but because the white base chalks too much. For this same reason, there are
limitations on the exterior use of certain Tube System Calibrated Colors .
All pigments contained in P&L Machine System Colorants are alkaliresistant and are unharmed by "green" plaster and masonry, but Colorants C and G are not recommended for tinting Vapex Masonry Paint Bases because they lack exterior color permanence.
CODING SYSTEM FOR CALIBRATED COLORS

FORMULAS
A typical formula for one P&L Machine System Calibrated Color reads as follows;
Calibrated Color
Base
Add Colorants Gallon Quart
2^10
Light
A 2k A 6 J 8J 2
The letters in the above formula stand for colorant designation and the numerals stand for the number of 48ths of a fluid ounce that must be added. A 24, for example, means 24/48 fluid ounce of Colorant A; J8 means 8/48 fluid ounce of Colorant J. To produce Calibrated Color 2510, 24/48 fluid ounce Colorant A and 8/48 fluid ounce Colorant J must be added to each short-filled gallon of Light Base. Some
formulas require more than one fluid ounce (i.e. more than 48/48 fluid ounce) of a given colorant. Such a formula is illustrated below:

H 1 02. 40 H 22
In the above example H 1 ounce 40 means one and 40/48 fluid ounces Colorant H. To produce Calibrated Color 3^10, one must add 8/48 fluid ounce Colorant D and one and 40/48 fluid ounces Colorant H to each short-filled gallon of Light Base.
CALIBRATED COLORS
The 747 Calibrated Colors in the Machine System include all but two of the 224 Tube System Calibrated Colors. The two exceptions are Polar Blue 1044 and Holly Green 1272* The Machine System Calibrated Colors also includes 144 of the 207 Intermix Colors.
