THE ART OF PRINTING.

From the telegraph, to printing, and the printing-press, is but a step;

and one that is naturally suggested. The origin of printing is involved

in mystery. Some think it was practiced as far back as the building of

Babylon. The Romans, we know, had metal stamps with which they marked

words and names on their various articles; but having no paper, they

could hardly be said to _print_. Printing from engraved blocks of wood,

was practiced by the Chinese nearly fifty years before the Christian

era. But the credit of first introducing movable types, is commonly

attributed to John Fust, or Faust, of Mentz, who is represented, in the

cut on the next page, as looking, with his associates, at the first

proof taken from movable types. This was supposed to be not far from the

year 1450. Between 1450 and 1455, the celebrated “Mentz Bible” appeared,

without date; and this was the occasion of the art being discovered by

the public. Next followed the “Psalter,” in 1457; and from this time,

printing rapidly spread throughout Europe. William Caxton was the first

to introduce printing into England, about 1474. The first book in which

Greek types appear, was printed in 1465; and the first using the Roman

character, in 1467.

Printing-presses were gradually improved. The old-fashioned press was

made of wood, with an iron screw that had a bar fitted in it; and to the

lower end of this screw was attached, horizontally, a flat piece of

wood, called the _platen_, which was brought down by means of the screw,

and pressed the paper on the face of the types, and thus the impression

was given. This kind of presses, however, soon gave place to those made

of iron. The Stanhope press was a great improvement on anything that had

gone before it; and the Caledonian press, invented by George Clymer, an

American, was a great improvement, in many respects, on the latter. The

press represented in the cut on the following page, on which Franklin

printed, was one of these old-fashioned hand-presses, on which it would

have been a hard day’s work to print twenty-five hundred impressions, or

twelve hundred and fifty sheets on both sides, in a day. After a time, a

plan was devised of obtaining impressions from types by means of

cylinders; and in 1804, the idea was started, of applying steam-power to

printing-presses. It was not, however, till after years of experiments,

and an immense outlay of capital, that the invention was brought to a

successful issue, so as to be advantageously applied in practice. When,

however, in 1814, the machine was completed, it was adopted in the

office of the London Times newspaper, and was thus spoken of in the

papers of the day.

“A new printing-press, or printing-engine, has recently excited the

attention of the typographical world. It is wrought by the power of

steam, and, with the aid of three boys, perfects nearly a thousand

sheets per hour. A common press, worked by two men, takes off but two

hundred and fifty impressions on one side, and requires eight hours to

_perfect_ a thousand sheets. Hence, three boys in one hour are enabled,

by this new application of the power of steam, to perform the labor of

two men for eight hours. Such are the present capabilities of this

engine: but as there is no limit to its required powers, and the size of

the _form_ is no obstacle to its perfect performance, it is proposed to

take impressions on double-demy, in which case three boys will, in one

hour, perform the labor of thirty-two men. This engine is now at work at

the printing-office of Bensley & Sons, near Fleet street, and another on

a similar (but less perfect) construction, has for some time past been

employed on a morning newspaper. In its general analogy, this press is

not unlike the rolling-press of copper-plate printers. The forms being

fixed on the _carriage_, are drawn under a cylinder, on which the sheet

being laid, and the ink distributed by an arrangement of rollers, the

impression is taken on one side. The sheet is then conveyed off by bands

to a second cylinder, around which it is conveyed on the _second form_,

and the _reiteration_ is produced in _perfect register_, without the aid

of _points_. All the manual labor is performed by a boy, who lays the

sheet of paper on the first cylinder, by one who takes it off from the

second cylinder, and by a third, who lays the sheets even on the _bank_.

As a further instance of economy in the materials, we may mention, that

the waste steam from the copper is carried in tubes round the entire

suit of offices, with a view to warm them.”

Passing on, over various improvements, we come, last of all, to what

thus far is the perfection of all printing-machines, _viz._, _Hoe’s

eight-cylinder power-press_, a view of which is given in the cut on the

following page. This immense printing-machine is thirty-three feet long,

fourteen feet and eight inches high, and six feet wide. It has one large

central cylinder on which the type is secured, and eight smaller

cylinders arranged around it, at convenient distances. Eight persons

supply the eight small cylinders with the sheets, and at each revolution

of the large cylinder, eight impressions are given off, the sheets being

delivered in neat order by the machine itself. The limit to the speed is

in the ability of the eight persons to supply the sheets. At the rate of

twenty-five hundred sheets to each, the press would give off the

unparalleled number of twenty thousand printed impressions per hour. The

press is thus far used exclusively for newspaper and similar printing.

What it may next be applied to, or what will be the next stride in the

rapidity and perfection of printing, only the future can reveal.

Before leaving the subject of printing, it may not be uninteresting to

mention, that a _composing_, or type-setting machine, is said to have

been recently invented, in Denmark. One who has seen it in operation,

says: “It is now in actual operation in the office of the Fædrelandet.

Instead of the usual cases and composing-sticks, and the compositor

standing at his work, we see a person sitting before a machine with keys

like a piano, which he plays on incessantly, and every touch on the

tangent is followed by a click; the letter already in its place in the

long mahogany channel prepared for it. The whole is excessively

ingenious. In fact it is fairy work. The most wonderful part is that it

distributes the already used types at the same time that it sets the new

page, and with an exactness perfectly sure. No mistake can ever occur.

The compositor, by this machine, does four times as much work as another

workman; but as he requires an assistant to line and page the set type,

this brings it to twice the amount of type set. The whole is so clean

and pleasant, that it will probably soon be a favorite employment for

women. The machine occupies a very small space, not more than a large

chair, and is beautifully made of hard woods, brass and steel. Its

success is now beyond all doubt. The proprietors of the Fædrelandet are

so gratified by the one they now have, that they have ordered another.

The price is twenty-four hundred Danish dollars. It will last,

apparently, for a century or two without repair. Mr. Sorenson, the

inventor, himself a compositor all his life, kindly shows the machine to

any visitor. Of course, a compositor can not set with this machine at

once; it will take a short time, a few days, for him to become familiar

with the details, but he is then a gentleman compared to his old

comrades.”
