Part 50

The last sheet of the form of the McCaskey Register Co. is cardboard, with the numbers 1 to 31 printed along the top. A movable metal "spud," or tip, is used to show the due dates of each invoice, and to enable the collection clerks to quickly find the desired copies of charges for the purpose of sending out statements from three to five days ahead of due dates.

=Styles of Type.= The size and style of type is a very important factor in all classes of work where legible manifolding results are wanted. There are several classes of type used in connection with billing machines. Different companies use different names in describing them. The four sizes of type used are as follows:

ELITE PICA MEDIUM ROMAN LARGE (or full) ROMAN

Elite. This style has come into general use in connection with correspondence. It gives a dignified style to a letter. It is the hardest type to keep clean—the most destructive to the rubber roll and typewriter ribbon of any type made. It also manifolds very poorly where a number of copies are used, as the type is so small that the sixth or seventh copy, and many times the third and fourth, are so blurred that it is impossible to tell an e from an a or an o.

This style of type is sometimes used for making up tabulated statements where it is desired to crowd a large number of figures to the inch.

Pica. This is the most generally used type of any. It manifolds quite well up to six and seven copies. It is possible to write only ten figures of this size to the inch.

Medium Roman. This is the next larger size type than the pica and, on account of it being larger, it gives better manifolding results. It also writes ten letters to an inch.

Large Roman. This is the size type which is used by railroad and steamship companies for typewriting their way-bills. It is possible to write only eight letters to an inch.

Gothic Type. The term Gothic indicates the style, and not the size of the type. If the small points at the top and bottom of the Roman type were removed (these points are called serifs) the effect would be that of Gothic type. A very pleasing combination on a billing machine is two different sizes of Gothic type, the larger size to be used for capital letters, the smaller size for the small (or lower case) letters. Recent practice has demonstrated the value of using capital Gothic letters of one size, as it increases the legibility of an order or an invoice.

In manifolding, numerals should always be of the "open" kind, that is, 1 2 3 4 5 6 7 8 9 0, and not 1 2 3 4 5 6 7 8 9 0, as the former are much the more legible.

=Carbon Paper.= There is no article which is so generally misused in the commercial world and which is so little understood as carbon paper. In order that the correct usage may be clearly understood a brief description of its manufacture is given.

The chief ingredients of carbon paper are oil, wax, paper, and color. Oils and waxes are used to give wearing surface, elasticity, and body to the color mixture. Tissue paper—generally of imported quality—with a fine, strong fiber is used. The quality must be first class in order to insure absence of holes and other imperfections in the sheets. Generally the sheets are cut 20 x 30 inches. A ream is regarded as containing 500 sheets. Three weights of paper are used, 4lb., 7lb., 10lb., respectively, meaning that 500 sheets of the above size of paper will weigh the number of pounds named, according to the thickness of the paper.

Color. The only really indelible color is black; that is because carbon is the basis of the color. The colors which are used are powders which have been ground as fine as possible. They are mixed in proper proportions with oils and waxes. Formerly the mixture was applied by hand, but great strides have been made in machinery for automatically applying the color evenly to the paper. It is important that the color or pigment be applied evenly to the paper and that it penetrates the fiber. Unless the paper retains the pigment, the carbon paper will not wear properly. The longer the color adheres to the paper, the longer it can be used.

Finish. The finish of carbon paper is the factor which is so little understood by the public. Carbon papers are finished with soft, medium, and hard finishes. The first will hardly rub off on the hand under pressure, the next will rub some, and the soft finish will smudge if pressed against the hand. Each finish is intended for a definite use, which will be explained later. The manifolding power of carbon paper depends absolutely on the typewriter itself, the hardness of the rubber roll, the touch of the operator, and the weight of paper, and lastly, the finish of coating on the paper. Two operators on the same typewriter can secure totally different results because one will have light, and the other heavy, touch. The regular rubber rolls which are furnished with typewriters are medium hard—in six months or a year they gradually grow harder, eventually becoming as hard as slate. If a typewriter is to be used for regular work as well as heavy manifolding, it should have two different rolls, one for each kind of work. There is no reason for using a medium hard rubber roll on the machine, getting poor results, and then blaming the carbon paper. Use a hard rubber roll on the machine and there will be no difficulty. Some makes of machines have interchangeable rolls (known as platens) which are very useful. It is the work of a minute only, to remove one and place the other on the machine.

Four-Pound Paper. This class of carbon paper has a heavy, sensitive coating, and is intended for heavy manifolding—for making from five to twenty copies. Soft-finish carbon papers are always used where heavy manifolding is to be done. The finish of the paper which is being written upon is also a factor. Papers with a hard finish—that is, a shiny surface—do not allow the color of the carbon paper to take hold, and yet a paper with the soft finish will allow the color to spread, and make a poor copy. This class of paper is also used for making a few copies on very light-stroke machines like the Hammond.

Seven-Pound Paper. This weight of paper is adapted for making from one to five copies. Being heavier than the four-pound, it will wear longer. If coated heavily it will give more impressions than if lightly coated, but the impressions will not be as clear and clean.

Ten-Pound Paper. This weight of paper is intended for use where one or two copies are wanted. Its weight enables it to stand the hard usage to which it is put. On one or two copies, the additional weight or thickness of the carbon paper does not affect the imprint. This class of paper is used with billing machines of all kinds.

Full Carbon Papers. This is a paper which is coated on both sides for making a multiplicity of copies on tissue. The pieces of carbon paper are placed between every other piece of tissue paper and manifold on the top of one sheet and the bottom of the next. This carbon paper is used to reduce the bulk of paper in the typewriter—one-half as much carbon paper being required. It is sometimes called double carbon paper, and is mostly used by railroads in making up way bills on yellow (dandelion grade) tissue paper.

Copy Carbon Papers. This paper is for use where it is necessary or desirable to make a carbon copy from which to make a letter-press copy. Hektograph carbons are for making carbon copies to be used in a hektograph.

Pencil Carbons. This class of carbon paper is made in the heavy grades of paper from seven-pound to twenty-pound and is made full carbon in the seven-pound weight.

Pen Carbon. This class of carbon paper is made in the seven-pound and ten-pound weights.

Troubles and Remedies. Carbon papers made in summer have different treatment in the matter of color mixture than those made in winter. Users should always remember that carbon paper which has lain unused all year has gradually dried out and depreciated in efficiency. The fresher a carbon paper the better—therefore it is not economy to buy too large a supply if it is liable to stand for more than six months. Never store carbon paper near heat, nor in the direct rays of the sun.

The one great difficulty experienced with carbon paper is the streaked effect called "treeing." This is caused by the carbon paper being inserted unevenly between the sheets of paper used with it. Once wrinkled, it remains so, and gives the streaked result as long as it lasts. To guard against this trouble, the operator should watch that the carbon paper is not wrinkled when inserting it between the sheets of paper, and should press the release lever on the typewriter to release the paper-feed rolls on the machine, after the paper is inserted in it, so that the unequal tension of the paper and carbon paper may adjust itself.

Durability of Color. Black paper made of carbon pigment is indelible and most durable. Blue or purple papers are next in the order of durability of color, and are made of aniline dyes. Green next, and red next. The fact is that red and green carbon papers should not be used for permanent records, as they will fade quickly.

Wearing Quality of Paper. Many times a typewriter will have a rubber roll (platen) which has become pitted and worn from age and the use of periods, commas, hyphens, and ditto marks. This is very destructive to carbon paper. New rubber rolls should be placed on the machine. It is not economy to use the cheap variety which can be purchased for 75 cents and which is nothing more than rubber hose drawn over a wooden core. The latter is not cylindrical and will give trouble. The type will print unevenly and cause bad alignment, for which the machine will be blamed.

=Blinds.= Blind is the name given to a sheet of paper used in connection with manifold work for preventing all of the information on the top sheets from being manifolded on certain of the sheets underneath.

For instance, in describing the scheme for providing the packing department with a description of the goods to be shipped, but with the quantity column blank, it will be remembered how a strip of paper of proper size wide enough to cover the quantity column was placed over the left side of the invoice from top to bottom. Therefore all quantities, instead of manifolding onto the packer's sheet, manifolded onto the strip of paper known as the blind.
