Paper Embossing
Embossing and debossing are the processes of creating either raised or recessed relief images and designs in paper and other materials. An embossed pattern is raised against the background, while a debossed pattern is sunken into the surface of the material but might protrude somewhat on the reverse side. Techniques Often used in combination with foil stamping, embossing alters the surface of paper stock or other substrates by providing a three-dimensional or raised effect on selected areas. The procedure requires the use of two dies: one that is raised and one that is recessed. The dies fit into each other so that when the paper is pressed between them, the raised die forces the stock into the recessed die and creates the embossed impression. A specific level of pressure is applied to the dies in order to squeeze the fibers of the paper, which results in a permanently raised area in the paper. When the dies are produced, a die maker engraves the desired image into several me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leather Crafting
Leather crafting or simply leathercraft is the practice of making leather into craft objects or works of art, using shaping techniques, coloring techniques or both. Techniques Dyeing The application of pigments carried by solvents or water into the pores of the leather. Can be applied to tooled or untooled leather, either for even coloration or to highlight certain areas. For example, application to a tooled piece can result in pooling in the background areas giving contrasts and depth. There are oil, alcohol, and water based leather dyes available. Although the water-based alternatives tend to not work as well due to poor penetration. Painting Leather painting differs from leather dyeing in that paint remains only on the surface while dyes are absorbed into the leather. Due to this difference, leather painting techniques are generally not used on items that can or must bend nor on items that receive friction, such as belts and wallets because under these conditions, the pai ...

Embossing (manufacturing)
Sheet metal embossing is a stamping process for producing raised or sunken designs or relief in sheet metal. This process can be made by means of matched male and female roller dies, or by passing sheet or a strip of metal between rolls of the desired pattern. It is often combined with foil stamping to create a shiny, 3D effect. Process The metal sheet embossing operation is commonly accomplished with a combination of heat and pressure on the sheet metal, depending on what type of embossing is required. Theoretically, with any of these procedures, the metal thickness is changed in its composition. Metal sheet is drawn through the male and female roller dies, producing a pattern or design on the metal sheet. Depending on the roller dies used, different patterns can be produced on the metal sheet. The pressure and a combination of heat actually "irons" while raising the level of the image higher than the substrate to make it smooth. The term "impressing" refers to an image ''l ...

Repoussé And Chasing
''Repoussé'' () or ''repoussage'' () is a metalworking technique in which a malleable metal is shaped by hammering from the reverse side to create a design in low relief. Chasing (French: '' ciselure'') or embossing is a similar technique in which the piece is hammered on the front side, sinking the metal. The two techniques are often used in conjunction. Many metals can be used for chasing and repoussé work, including gold, silver, copper, and alloys such as steel, bronze, and pewter. These techniques are very ancient and have been extensively used all over the world, as they require only the simplest tools and materials, and yet allow great diversity of expression. They are also relatively economical, since there is no loss or waste of metal, which mostly retains its original size and thickness. Toolmarks are often intentionally left visible in the result. A few among many famous examples of repoussé and chasing are the prehistoric Gundestrup cauldron, the mask on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Image Embossing
Image embossing is a computer graphics technique in which each pixel of an image is replaced either by a highlight or a shadow, depending on light/dark boundaries on the original image. Low contrast areas are replaced by a gray background. The filtered image will represent the rate of color change at each location of the original image. Applying an embossing filter to an image often results in an image resembling a paper or metal embossing of the original image, hence the name. Technical details The emboss filter, also called a directional difference filter,"Computer imaging: Digital image analysis and processing (Second ed.)" by Scott E Umbaugh, (2010) will enhance edges in the direction of the selected convolution mask(s). When the emboss filter is applied, the filter matrix is in convolution calculation with the same square area on the original image. So it involves a large amount of calculation when either the image size or the emboss filter mask dimension is large. The embo ...

Embossing Tape
Embossing tape is a labelling medium usually of hard plastic. Embossing tape is used with embossing machines, often handheld. The company name and trademark "Dymo" is often associated with this sort of label as their CEO Rudolph Hurwich first introduced it as a consumer product in 1958. Embossing tape have largely been replaced with thermal transfer printing tape used by label printers, but is returning in popularity as 'vintage' looks become increasingly popular. Method The machine features multiple embossing dies arranged on two parallel wheels. Each character has one positive die and one negative die. Typically all of the negative dies are constructed on one rigid wheel, while all the positive dies are constructed on a divided flexible wheel, similar to the daisy wheel of a daisy wheel printer. The user turns the wheel to align the desired character with the tape and then presses a trigger, which forces one positive die against the tape, which deforms some of the tape into the ...

Braille Embosser
A braille embosser is an impact printer that renders text as tactile braille cells. Using braille translation software, a document or digital text can be embossed with relative ease. This makes braille production efficient and cost-effective. Braille translation software may be free and open-sourced or paid. Blind users tend to call other printers "ink printers," to distinguish them from their braille counterparts. This is often the case regardless of the type of printer being discussed (e.g., thermal printers being called "ink printers" even though they use no ink). As with ink printers and presses, embossers range from those intended for consumers to those used by large publishers. The price of embossers increase with the volume of braille it produces . Types The fastest industrial braille embosser is probably the $92,000 Belgian-made NV Interpoint 55, first produced in 1991, which uses a separate air compressor to drive the embossing head and can output up to 800 brail ...

Harmonica
The harmonica, also known as a French harp or mouth organ, is a free reed wind instrument used worldwide in many musical genres, notably in blues, American folk music, classical music, jazz, country, and rock. The many types of harmonica include diatonic, chromatic, tremolo, octave, orchestral, and bass versions. A harmonica is played by using the mouth (lips and tongue) to direct air into or out of one (or more) holes along a mouthpiece. Behind each hole is a chamber containing at least one reed. The most common is the diatonic Richter-tuned with ten air passages and twenty reeds, often called the blues harp. A harmonica reed is a flat, elongated spring typically made of brass, stainless steel, or bronze, which is secured at one end over a slot that serves as an airway. When the free end is made to vibrate by the player's air, it alternately blocks and unblocks the airway to produce sound. Reeds are tuned to individual pitches. Tuning may involve changing a reed’s length ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overblowing
Overblowing is the manipulation of supplied air through a wind instrument that causes the sounded pitch to jump to a higher one without a fingering change or the operation of a slide. Overblowing may involve a change in the air pressure, in the point at which the air is directed, or in the resonance characteristics of the chamber formed by the mouth and throat of the player. (The latter is a feature of embouchure.) In some instruments, overblowing involves the direct manipulation of the vibrating reed(s), and/or the pushing of a register key while otherwise leaving fingering unaltered. With the exception of harmonica overblowing, the pitch jump is from one vibratory mode of the reed or air column, e.g., its fundamental, to an overtone. Overblowing can be done deliberately in order to get a higher pitch, or inadvertently, resulting in the production of a note other than intended. Characteristics In simple woodwind instruments, overblowing can cause the pitch to change into a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
