Photo Engraving

Photo engraving is the process of engraving using photographic techniques. This unique and innovative concept is widely used for replicating graphic objects by transferring the image photographically onto a plate or some other surface and then engraving. Photo engraving is a very popular process and is used to create printing plates, presentation plaques, printed circuit boards, embossing dies boards and foil-stamping dies.

The photo engraving technique involves using a photosensitive material, known as photoresist. This material, which is resistant to acids or other engraving objects, is employed to a metal to be etched. It is then exposed to light, normally heavy ultraviolet rays, through a photographic negative. This helps it to harden at places where the negative permits light to pass. It is then washed in a solvent that eliminates the untempered components, thereby developing the photoresist. After this process, the metal to be carved is exposed to any etching compound or acid which liquefies the exposed parts of the metal.

One of the popular methods of photo engraving results in a shallow depression in the metal. This method is mainly used for printed circuit boards, decorative purposes or for intaglio printing plates. The etching is usually done on brass or copper. Another method of engraving is used to make a deep etching with sloped shoulders. For this process, the metal, mostly magnesium or zinc, is placed facedown and a combination of soap-like oil and nitric acid is poured onto it. This method of engraving is popular for making embossing dies, foil stamping dies and printing plates.

Today, there are several companies that utilize the latest photo engraving technology to replicate an image on gold, silver, brass, copper, acrylic and stainless steel. The most popular photo engraving products available in stores include gold and silver pedants, name cardholders, promotional key rings, compact mirror, badges, lighters and acrylic plaques.

Laser Engraving

 Laser engraving is a method using lasers to mark, engrave or etch on an object. Laser engraving techniques are considered technical, and in most cases, a computer system is utilized to operate the laser head. Even though the whole process is considered complex, one can achieve very clean and precise engravings. Laser engraving does not include tool bits that contact the engraving surface and wear out. This is a benefit when compared to the other engraving technologies where bit heads need to be changed frequently.

Laser engraving is done by focusing a parallel beam of light (laser) through a lens to a pinpoint where the heat produced is vaporizing the subject material. Laser engraving techniques are more widely used for specifically designed laser-able materials. These include novel metal alloys and polymer.

Laser engraving has several advantages when compared to conventional engraving methods. As laser engraving uses a beam of light as a tool, it only produces a non-contract mark that results in less wear and tear on tooling and other related expenses. There is also less chance for product deformation and damage. Another advantage is that lasers are much faster than other conventional methods of product imprinting and also provide better versatility in material choices. Laser engraving can be applied to wood, plastic, glass; coated metals and laser cut machine gaskets.

In certain cases where physical modification of a surface by engraving is unsuitable, there is an alternative way known as laser marking. Laser marking is a broad term which covers a wide range of surfacing techniques such as hot-branding and printing.

Today?s laser engraving equipments are affordable, easy to use and maintain. Most of the latest laser engraving equipment also offer greater speed and adaptability.

Engraving - Types And Varieties

Engraving is a piece of carved structure, which is made with incisions designed into a hard and flat surface by carving grooves on it. The results of engraving are decorative objects that provide unique d?cor to the surrounding arena. You can carve engravings on materials like silver, gold, copper, relief print block, wood or copper. With proper backgrounds, different types of engravings truly add a touch of wonder and variety to room d?cor.

Process of engraving

The process of engraving is purely scientific. The engravers use a hardened steel tool called burin to cut design into the surface, mostly that of copper. The burin cuts a unique quality of line that is characterized by its steady appearance and clean edges. The gravers often use angle tint tool that is more commonly used in printmaking. When the gravers have to carve on larger areas, they use Florentine liner tool that carves multiple engravings. While flat gravers are particularly used for doing fill work on letters, the round gravers are used specially on silver, nickel and steel to create bright cuts. However, other tools like roulets, burnishers and mezzotint rockers are used particularly to bring in a texturing effect.

Engravings are used on different forms like paintings, postage stamps, walls and other items. Following are the different types of engravings:

Modern engravings

These types of hand engravings are basically available in the firearms and other metal weaponry, musical instruments and jewelry pieces. In most of industrial uses like production of Intaglio plates for commercial purposes, hand engravings are often replaced with CNC engravings done by milling machines.

Laser engraving

It is a practice of using lasers to engrave, mark or etch on an object. Although laser engravings are more applicable on "laserable" materials like polymer and novel metal alloys, they are mostly applicable on materials like plastics, coated metals, stones and glasses, woods and natural materials.

Music engraving

This is the art of drawing music notations at high quality. In the early 20th century, music staff paper was printed onto vellum or onionskin, which makes it possible to easily rectify any type of mistakes done while engraving. With the advent of personal computers, hand engravings have basically become a past. Now individual parts of an orchestral score can be easily extracted and printed using numerous computer programs.

To decorate your home and office, you can use hand engravings and give an aesthetic touch to the d?cor.

Little Known Uses Of Engraving ? Tips And Techniques!!

Engraving and its Many Applications

What is Engraving?

When lines or grooves are carved, etched or cut into a hard surface, we say it has been engraved. Engraving is commonly used on materials like metal, wood and stone. There are many applications for engraving, both decorative and functional. For example, printing, manufacturing and jewelry making all commonly incorporate engraving to produce the final product.

Engraving in Printing

Engraving is often used for printing. Most paper money produced today is engraved, and wedding invitations, personalized stationery, business cards and birth announcements are commonly custom ordered and engraved. The words and designs to be printed are engraved in a metal die, and the grooves are filled with ink. The die is then pressed to a card or paper, transferring the ink onto the paper. If you run your fingertips over the paper, you can feel the raised ink of the letters.

Laser Engraving

Laser engraving is currently a popular form of engraving. A laser is used to cut designs into the surface of the object being engraved. It is easier to get into small or difficult spots with a laser than with a hand tool. The laser is often used in conjunction with a computer program that controls its movements. Laser engraving can be used to etch a logo and phone number on marketing tools such as pens, key chains and paperweights. Because the logo is engraved in the item, it does not rub off with use over time as printed logos often do. Leather, glass and plastic can also be engraved with lasers, and laser engraving can be used for industrial applications.

Engraving in Art

Engraving was commonly used to illustrate books and newspapers before photography was invented. Until the late 19th century, wood engraving was used to produce most of the pictures seen in printed material. An artist would draw the image on a wood block, then an engraver would engrave the picture into the wood. Engraving was also used to reproduce paintings.

Engraving Jewelry

Engraved jewelry has been around for a long time, and engraved designs have been seen on jewelry that is thousands of years old. It is common to give engraved jewelry as a gift. Silver and gold jewelry is often engraved with the name or initials of the owner or an inscription. Enamel is sometimes used to fill the grooves made by engraving the jewelry. Designs have long been engraved on gemstones, and jade and ivory are commonly engraved with beautiful images.

Engraving Gifts

Giving engraved items as gifts has been popular for years, and there are several shops that specialize in engraving gifts. Jewelry such as rings and bracelets are often engraved with initials or a short message. Pendants and lockets are frequently engraved with a dedication. Popular engraved gifts for men include cuff links, pocketknives, money clips and flasks. Aside from jewelry, popular engraved gifts for women include trinket boxes and key chains. For children, banks engraved with the child?s name are appreciated, and engraved photo frames make a nice gift for everyone. WANT TO KNOW MORE ABOUT ENGRAVING?
