Animation photo transfer process

Last updated

The animation photo transfer process (APT process) was a photographic transfer system that can photographically transfer lines or solid blocks of colors onto acetate sheets (cels). A similar process is used in making the stencils for silk screen printing. The process relies on UV-sensitive inks that cure when exposed to light and stick to the plastic sheet, while the ink in the non-exposed areas is chemically removed from the sheet.

Advantages

Compared to the earlier xerography process used by Disney, the lines can be controlled better and multiple copies made quickly. The drawings are photographed on high-contrast sheet film, and these negatives are then exposed onto the cels. A line on an animated character can be in color instead of just black. This is known as self-colored lines. (Xerographic lines were rendered in color too, when colored toners became available.)

Examples

This process was used on Disney's animated features, such as The Black Cauldron , The Great Mouse Detective , Oliver & Company , and The Little Mermaid .

<span class="mw-page-title-main">Animation</span> Method of creating moving pictures

Animation is a filmmaking technique by which still images are manipulated to create moving images. In traditional animation, images are drawn or painted by hand on transparent celluloid sheets (cels) to be photographed and exhibited on film. Animation has been recognized as an artistic medium, specifically within the entertainment industry. Many animations are computer animations made with computer-generated imagery (CGI). Stop motion animation, in particular claymation, has continued to exist alongside these other forms.

Halftone is the reprographic technique that simulates continuous-tone imagery through the use of dots, varying either in size or in spacing, thus generating a gradient-like effect. "Halftone" can also be used to refer specifically to the image that is produced by this process.

The complex also houses the offices for the company's many divisions, with the exception of Pixar Animation Studios, Lucasfilm, and 20th Century Studios, which remains on its namesake lot in nearby Century City as tenants of Fox Corporation.

<i>Tron</i> 1982 science fiction film by Steven Lisberger

Tron is a 1982 American science fiction action adventure film written and directed by Steven Lisberger from a story by Lisberger and Bonnie MacBird. The film stars Jeff Bridges as Kevin Flynn, a computer programmer and video game developer who is transported inside the software world of a mainframe computer where he interacts with programs in his attempt to escape; it also stars Bruce Boxleitner, David Warner, Cindy Morgan, and Barnard Hughes. Tron, along with The Last Starfighter, was one of cinema's earliest films to use extensive computer-generated imagery (CGI).

While the history of animation began much earlier, this article is concerned with the development of the medium after the emergence of celluloid film in 1888, as produced for theatrical screenings, television and (non-interactive) home video.

<span class="mw-page-title-main">Darkroom</span> Room which can be made fully dark to allow for development of photographs and film

A darkroom is used to process photographic film, make prints and carry out other associated tasks. It is a room that can be made completely dark to allow the processing of light-sensitive photographic materials, including film and photographic paper. Various equipment is used in the darkroom, including an enlarger, baths containing chemicals, and running water.

Color photography is photography that uses media capable of capturing and reproducing colors. By contrast, black-and-white or gray-monochrome photography records only a single channel of luminance (brightness) and uses media capable only of showing shades of gray.

<span class="mw-page-title-main">Traditional animation</span> Animation technique in which frames are hand-drawn

Traditional animation is an animation technique in which each frame is drawn by hand. The technique was the dominant form of animation, until the end of the 20th century, when there was a shift to computer animation in the industry, specifically 3D computer animation.

Xerography is a dry photocopying technique. Originally called electrophotography, it was renamed xerography—from the Greek roots ξηρόςxeros, meaning "dry" and -‍γραφία-‍graphia, meaning "writing"—to emphasize that unlike reproduction techniques then in use such as cyanotype, the process of xerography used no liquid chemicals.

<span class="mw-page-title-main">Cel shading</span> Computer graphics rendering technique used to mimic the look of 2D animation

Cel shading or toon shading is a type of non-photorealistic rendering designed to make 3D computer graphics appear to be flat by using less shading color instead of a shade gradient or tints and shades. A cel shader is often used to mimic the style of a comic book or cartoon and/or give the render a characteristic paper-like texture. There are similar techniques that can make an image look like a sketch, an oil painting or an ink painting. The name comes from cels, clear sheets of acetate which are painted on for use in traditional 2D animation.

Photogravure is a process for printing photographs, also sometimes used for reproductive intaglio printmaking. It is a photo-mechanical process whereby a copper plate is grained and then coated with a light-sensitive gelatin tissue which had been exposed to a film positive, and then etched, resulting in a high quality intaglio plate that can reproduce detailed continuous tones of a photograph.

Lenticular printing is a technology in which lenticular lenses are used to produce printed images with an illusion of depth, or the ability to change or move as they are viewed from different angles.

Color printing or colour printing is the reproduction of an image or text in color.

A cel, short for celluloid, is a transparent sheet on which objects are drawn or painted for traditional, hand-drawn animation. Actual celluloid was used during the first half of the 20th century. Since it was flammable and dimensionally unstable, celluloid was largely replaced by cellulose acetate. With the advent of computer-assisted animation production, the use of cels has been all but abandoned in major productions. The Walt Disney Animation Studios stopped using cels in 1990, when Computer Animation Production System (CAPS) replaced this element in their animation process. In the next decade and a half, other animation studios phased cels out as well.

The Computer Animation Production System (CAPS) was a proprietary collection of software, scanning camera systems, servers, networked computer workstations, and custom desks developed by The Walt Disney Company and Pixar in the late 1980s. Although outmoded by the mid-2000s, it succeeded in reducing labor costs for ink and paint and post-production processes of traditionally animated feature films produced by Walt Disney Animation Studios (WDAS). It also provided an entirely new palette of digital tools to the animation filmmakers.

Barrier-grid animation or picket-fence animation is an animation effect created by moving a striped transparent overlay across an interlaced image. The barrier-grid technique originated in the late 1890s, overlapping with the development of parallax stereography (Relièphographie) for 3D autostereograms. The technique has also been used for color-changing pictures, but to a much lesser extent.
