Inkpot

“ The ink being mixed, a little is taken up on the point of a palette knife and smeared along the face of the leather roller and then worked vigorously upon the inking slab, until the ink is thoroughly distributed upon both roller and slab. Do not attempt to thin the ink so as to lessen the labor of distributing the ink, as that will only render the collotype print flat and weak. The ink must be stiff and spare. Now remove the soaking fluid with a very soft sponge, and blot off with fine plate paper, then proceed to roll up with the leather roller, until the image just shows nicely on the plate. ”

“ Hodges, said that logwood ink penetrates the paper. If this ink has been on here twenty-five years it penetrates the paper.
Sometimes an accident happens in our favor; a piece of that will was torn off this morning. You see the edge there torn off slanting. You see that "o-f"; how much that ink has sunk into that paper. Not the millionth part of a hair. It lies dead upon the top. Just see how the ink went in there—not a particle. It lies right on top. I would call that "float." There is the other edge. There is where the ink stops. It has not entered a particle. ”

“ The ink, first of all, must produce an indelible cancellation; that is, it must be relatively indelible as compared with the ink used for printing the postage stamps. The post-mark made with the ink must dry quickly in order that the mail matter may be handled immediately without any blurring or smearing of the post-mark.
Both this property and the property of the indelibility involve the question of the rate at which the ink penetrates or is absorbed by the fibre of the paper. A satisfactory ink does not harden or form a crust on the ink-pad on exposure to air. ”

“ After experimenting with various substances, and among others with Prussian blue and indigo dissolved in various ways, he found the sulphate of indigo to fulfil all the required conditions and, when added in the proper proportion to a tanno-gallate of iron ink, it yielded an ink which is agreeable to write with, which flows freely from the pen and does not clog it; which never moulds, which, when it dries on the paper, becomes of an intense pure black, and which does not fade or change its color however long kept. ”

“ We quote from page 366;—"The ink which the ancients generally used, was composed of lamp-black mixed with gum, as we are informed by Dioscorides and others, who give the receipt [recipe?] for making it. Ink of this kind may be called carbonic: it possess the advantages of extreme blackness and durability, the writing remaining fresh so long as the substance on which it is written exists; but as it does not sink into the paper, it is liable to the great inconvenience of being easily and entirely removed ”

“ These ink-wells with rubber tops can be obtained for about one shilling each, but for staff and committee use a better variety should be ordered as the rubber degenerates quickly under the chemical action of the ink. Ink-wells should preferably be associated with pen-racks rather than with pen-trays. A rack sorts the pens and pencils out automatically in a visible order, while a tray wastes a large amount of time annually, owing to the groping and examining and fruitless fumblings necessitated before the right pen or pencil is found among its fellows. ”

“ A copper plate is smoothly covered with a very thin layer of printer's ink, by means of a printer's roller. When the thumb is pressed upon the inked plate, no ink penetrates into the delicate furrows of the skin; the ridges only are inked, and these leave their impression when the thumb is pressed on paper. Turpentine readily removes the ink from the skin. A simpler process is to slightly smoke a piece of smooth metal or glass, press the thumb upon it, and then make the imprint on a bit of gummed paper that is slightly dampened. ”

“ Fire-proof ink for writing or printing on incombustible paper is made according to the following recipe: Graphite, finely ground, 22 drams; copal or other resinous gum, 12 grains; sulphate of iron, 2 drams; tincture of nutgalls, 2 drams; and sulphate of indigo, 8 drams. These substances are thoroughly mixed and boiled in water, and the ink thus obtained is said to be both fire- proof and insoluble in water. When any other color but black is desired, the graphite is replaced by an earthly mineral pigment of the desired color. ”

“ The great defect to be avoided and prevented is the want of durability. The writing ink of the ancients was characterized by great permanency, being composed of finely pulverized carbon mixed with a mucilaginous or adhesive liquid. India or China Ink is of this composition: it is formed of lamp-black and size or fine animal glue, with the incidental addition of perfumes. It is used in China with a brush, both for writing and painting on Chinese paper ”

“ To fix lead pencil marks on sketches so that they cannot be readily erased, sponge them with milk carefully skimmed, then lay blotting paper over them and iron with a hot flat-iron.
To have the ink preserve its fluidity and to keep out all dirt and dust, keep the cover on the ink slab; the mistake is often made of putting too liberal a supply of water in ink well, which causes a waste of both time and ink; no more should be prepared than to meet immediate requirements. ”

“ Next dissolve one ounce of sulphate of iron in half an ounce of distilled water by the aid of heat; mix the solutions together by a few minutes' agitation, when a good ink will be formed, perfectly clear, which will keep good any length of time without depositing, thickening, or growing mouldy, which latter quality is a great desideratum, as ink undergoing that change becomes worthless. It will not do to mix with ordinary ink, nor must greasy paper be used for writing on with it."— Chemical News (1862) . ”

“ It penetrated the substance of the paper (as caustics or powerful chemical solvents and corrosives act on the organic fibre) : it bit in, or burned in,—and was therefore well named ENCAUSTON and Incaustum.
CHEMISTRY or COMPOSITION of INK.
We do not propose to furnish recipes, prescriptions, directions or instructions for the manufacture of this article. No mere statement in words can enable any one to arrive at perfection, or excellence, or practical success in the production of this article, or any articles whatsoever. ”

“ Loss of Half-tone arises from the print layer becoming too moist, when the more delicate half-tones fail to print. Dry with blotting paper, and immerse for five minutes in a bath of alcohol; this will take up the water, and the succeeding impressions will be greatly improved.
Uneven Inking.—It sometimes occurs, particularly in pictures which should show a white ground, that the latter takes more ink in one part than another. This usually arises from an unequal111 thickness of the sensitive coating. ”

“ In the engraved wood block, as in the printing type, it is a projection in the wood or metal which, being inked and passed under a press, leaves on paper its lines in black. Naturally then the intercalation of an engraving of this kind in typographical composition is made without difficulty, and the impression of both is taken at once. On the other hand, a line engraving is obtained from incised lines on a plate of copper; that is, an instrument called a burin traces the lines, which are filled with greasy ink. ”

“ Hither came the paper from its final drying after the size bath, and the workers stood with a heap of sheets on one side of them and a little stack of polished zinc plates on the other. With her left hand each girl snatched a sheet of paper, with her right a plate of zinc; and then she inter-leaved the paper with the metal until a good wad rose in her crib. The paper was now ready for the glazing rollers, and men, who tended these massive machines, ran the sheets and zinc wads between the steel rollers, backward and forward twice and thrice under tremendous strain. ”

“ When there is a question as to whether a paper is tub or engine sized, it can be usually decided by wetting the forefinger and thumb and pressing the sheet between them. If tub-sized, the glue which is applied to the surface will perceptibly cling to the fingers.
TO TEST THE INK RESISTING QUALITY OF PAPER.— Draw a heavy ink line across the sheet. If the paper is poorly sized, a feathery edge will appear, caused by spreading of the ink. Slack-sized paper will be penetrated by the ink, which will plainly appear on the reverse side of the sheet. ”

“ Copying ink should never be used for "record" purposes as it is affected by changes of the temperature.
India ink, sometimes called China ink, or as formerly known by the ancients and in classical and later times "Indian ink," is now used more for drawing and engrossing than it is for commercial purposes. It belongs to the "carbon" class and in some form was the first one used in the very earliest times. In China it is applied with a brush or pith of some reed to the "rice" paper also there manufactured. ”

“ Mrs. Bell had thought of taking this inkstand out, and putting in some spools, or something else which Mary Erskine would be able to use. But Mary herself would not allow her to make such a change. She said it was true that she could not write, but that was no reason why she should not have an inkstand. So she filled the inkstand with ink, and furnished the desk completely in other respects, by putting in six sheets of paper, a pen, and several wafers. The truth was, she thought it possible that an occasion might arise some time or other, at which Albert might wish to write a letter ”

“ A good India ink is jet black, flows easily, lies close to, does not stand upon or sink into the paper, and has an even lustre, the latter being an indication of fineness. The more perfect the incorporation of the lamp-black with the water the easier the ink will flow, the less liable it is to clog the instruments, the more even and sharp the edges of the lines, and the finer the lines that may be drawn. ”

“ In the case of inks that do not contain iron, or when the writing was in carbon or aniline typing ink, this method of incineration will prove unsuccessful.
Writing that has been done with an ordinary lead pencil can usually be rendered visible by carefully regulating the heat during the incineration, so as not to burn away the graphite. Marks done with a red pencil are, as a rule, burned away with the paper, but blue pencil marks usually persist owing to the presence of an iron compound in the pigment. ”

“ Rolling up.—Apply the inking roller with light pressure to the nearest edge of the plate, and roll backwards and forwards over its surface several times; an experienced printer will at once perceive the condition of the surface. For the first inking a stiffish ink should be used, as the plate will not then so readily become dirty. By repeated rolling in different directions, and what is of equal importance, with varying pressure, endeavour to distribute the ink with perfect evenness, and with a view of producing a clear and vigorous inking, which will yield a similar perfect impression. ”

“ These balls are leather pads, on which the greasy ink, made of lampblack and oil, is spread, to more easily rub the forme after each blow. Ordinarily the inker had two functions: he prepared the ink, distributed it, and kept his eye on the printed sheets to correct faults, blots, and difference of tint. Here the workman is simply occupied by the balls. Printed sheets and prepared paper are on a table by the side of the press. This press is composed of the rolling chase, the tympan, and the "frisket," a smaller tympan, which work against one another. ”

“ The inking and cleansing of the plate, always dirty and disagreeable work, has hitherto been done only by hand. All the manipulations of copper-plate work are slow and difficult: they present many obstacles to the use of labor-saving machinery.
In lithography the design to be printed, which may be engraved on stone or copper, or written with pen on paper, is transferred by a greasy ink upon the smooth surface of a stone of peculiar fineness and firmness. ”

“ In copperplate printing the whole of the plate is first inked, the flat surface is then cleaned, leaving ink in the incisions or trenches cut by the engraver, so that, when dampened paper is laid over the plate and pressure is brought to bear, the paper sinks into the incisions and takes up the ink, which makes an impression in line or lines on the paper. ”

“ The requisites of a good black writing ink or black writing fluid require it to flow readily from the pen, to indicate in a short time a black color and to penetrate the paper to an appreciable degree, and more important than all the rest, to be of great durability. When kept in a closed vessel no sediment of any account should be precipitated, although such will be the case in open ink-wells, and this the quicker the more the air is permitted to get to it. ”

“ It causes, however, such a decided contraction of parchment as to be utterly useless, but for paper MSS. is excellent. The metallic sulphides generally pronounced harmless, causes the writing to soften and become illegible in a short time. On the other hand, yellow prussiate of potash, with acetic acid in successive operations is of great service in treating the most perplexing palimpsests.
Ink which badly corrodes a steel pen need not necessarily be condemned; it may contain just the qualities which make it bind to the paper and render it more durable. ”

“ Indigo has been recently imported,—a substance whose composition I have not yet investigated. The dyers make theirs from the dark crust that gradually accumulates on brass-kettles. Ink is made also from torches (pine-knots) , and from charcoal pounded fine in mortars. "The cuttle-fish" has a remarkable quality in this respect; but the coloring-matter which it produces is not used in the manufacture of ink. All ink is improved by exposure to the sun's rays. Book-writers' ink has gum mixed with it,—weaver's ink is made up with glue. ”
