2. Photoengraving - Wikipedia

   en.wikipedia.org/wiki/Photoengraving

   A print made in 1907 from a photoengraved plate. It reproduces a sketch of Parga's castle made by Ludwig Salvator.. Photoengraving is a process that uses a light-sensitive photoresist applied to the surface to be engraved to create a mask that protects some areas during a subsequent operation which etches, dissolves, or otherwise removes some or all of the material from the unshielded areas of ...

3. LilyPond - Wikipedia

   en.wikipedia.org/wiki/LilyPond

   One of LilyPond's major goals is to produce scores that are engraved with traditional layout rules, reflecting the era when scores were engraved by hand. LilyPond is cross-platform, and is available for several common operating systems; released under the terms of the GNU General Public License, LilyPond is free software and part of the GNU ...

4. Potrace - Wikipedia

   en.wikipedia.org/wiki/Potrace

   FontForge can use Potrace to import a bitmap image into a font. Potrace is also used by the music engraving program LilyPond. An open-source progressive web app that uses Potrace is SVGcode. Potrace's input and output is black and white (colored images are greyscaled before processing). However, Inkscape is capable of producing color images by ...

5. Rotogravure - Wikipedia

   en.wikipedia.org/wiki/Rotogravure

   The desired pattern is achieved by engraving with a laser or a diamond tool, or by chemical etching. If the cylinder is chemically etched, a resist (in the form of a negative image) is transferred to the cylinder before etching. The resist protects the non-image areas of the cylinder from the etchant. After etching, the resist is stripped off.

7. Photogravure - Wikipedia

   en.wikipedia.org/wiki/Photogravure

   The image is etched onto the copperplate by the ferric chloride, creating a gravure plate with tiny "wells" of varying depth to hold ink. The pattern formed by the aquatint grain or the screen exposure creates minute "lands" around which the etching occurs, giving the copperplate the tooth to hold ink.

8. Photochemical machining - Wikipedia

   en.wikipedia.org/wiki/Photochemical_machining

   Photochemical machining (PCM), also known as photochemical milling or photo etching, is a chemical milling process used to fabricate sheet metal components using a photoresist and etchants to corrosively machine away selected areas. This process emerged in the 1960s as an offshoot of the printed circuit board industry.

9. Laser engraving - Wikipedia

   en.wikipedia.org/wiki/Laser_engraving

   Sub-surface laser engraving is the process of engraving an image in a transparent solid material by focusing a laser below the surface to create small fractures. Such engraved materials are of high-grade optical quality (suitable for lenses, with low dispersion) to minimize distortion of the beam. BK7 glass is a common material for this ...
