TYPE-METAL RELIEF PLATES.

A SUPERIOR SUBSTITUTE FOR WOOD-CUTS

AT MUCH LOWER PRICES.

Persons desiring illustrations for Books, Newspapers, Catalogues,

Advertisements, or for any other purposes, can have their work done by

us promptly and in the best style.

OUR RELIEF PLATES are engraved by photo-chemical means; are mounted on

blocks type-high ready for use on any ordinary press, and will wear

longer than the common stereotype plates.

They have a perfectly smooth printing surface, and the lines are _as

deep, as even,_ and _as sharp_ as they could possibly be cut by hand.

ELECTROTYPES may be made from them in the same manner as from

wood-cuts.

COPY. The engraving is done either from prints or pen-drawings. Almost

all kinds of prints can be re-engraved directly from the copy,

provided they be in _clear, black lines_ or stipple, and on _white_ or

only slightly tinted paper.

Pen drawings, suitable for engraving by us, must be made with

_thoroughly_ BLACK ink, on _smooth, white_ paper. They should usually

be made twice the length and twice the width of the plates desired.

When such drawings cannot be furnished us, we can produce them from

photographs, pencil sketches, or designs of any kind accompanied with

proper instructions. Photographs taken in the usual way, and of any

convenient size, we can use.

CHANGE OF SIZE.--Wood-cut prints of the coarser kind may often be

reduced to half their lineal dimensions, while others will admit of

very little reduction, and some of none at all.

Most lithographic and steel-plate prints will admit of no reduction.

Very fine prints of any kind may be _enlarged_ moderately without

detriment.

Any prints which cannot be satisfactorily reduced or enlarged may be

_redrawn_ and thus brought to any desired size.

In all cases of reduction and enlargement, the relative proportions

remain unchanged.

PROOFS.--Whenever desired, we will furnish tintype proofs of the

drawings made by us, for approval or correction, before engraving. A

printed proof is furnished with each plate.

TIME.--We cannot usually engage to fill an order for a single plate in

less than from three to six days; larger orders will require longer

time.

ESTIMATES will be promptly furnished when desired. That these may be

definite and correct, the copy to be used--whether print, photograph,

sketch, or drawing--should always be submitted for our examination,

together with a distinct statement of the size of plate wanted, and of

any other details to be observed.

TERMS.--To insure attention, all orders must be accompanied by an

advance of half the price charged, the balance to be paid on delivery.

ELECTROTYPING AND PRINTING.--We have recently added to our

establishment excellent facilities for making electrotypes, and also

three power presses specially fitted for printing plates of all sizes

in the finest manner.

ARTIFICIAL LIGHT.--We have just introduced this most important

facility, which enables us to prosecute our work _in cloudy weather_,

and to push forward hurried orders _in the night_.

REFERENCES.--Our plates are now used by the principal publishers in

this city, and by most of the leading houses in every State in the

Union.

OUR GENERAL CIRCULAR contains a few specimens of the various kinds of

our work, and will be sent on receipt of stamp. We have just prepared

five special circulars, as follows:

No. 1. Portraits and Figures.

No. 2. Buildings and Landscapes.

No. 3. Machinery and Apparatus.

No. 4. Maps, Autographs, and Ornamental Lettering.

No. 5. Reproductions from Wood-Cuts, Steel-Plate Prints, and

Lithographs.

These will be furnished at _ten cents_ each.
