Adobe PDF Print Engine

The Adobe PDF Print Engine – APPE – is a software platform of ADOBE, specializing in the processing of PDF files and print rendering. It follows the widespread PostScript Level III print language or CPSI (Configurable PostScript Interpreter).

Currently, the version 3 of the Adobe PDF Print Engine is available, which was extended by the Mercury RIP architecture. By parallel processing, the engine is able to process on a modern quad-core system four instances of APPE simultaneously on the same PDF file, resulting in a much faster ripping process. In large RIP environments, four computers each with four processor cores can work at the same time on a PDF file.

According to Adobe, the APPE RIP is the fastest available technology. Using PDF / X-4 customer data, we at Proof GmbH observed some absurd long calculation times (3.75 hours for one page with the APPE 2.5 in two parallel instances), which has been referred to by Adobe as “normal” because of the complexity of the file processed.

Unlike PostScript Level III the APPE does not support PostScript. A PostScript file must be converted to a PDF file first in order to be processed by the APPE.

Anaglyph

An anaglyph picture is a printed or screen displayed 3D image that can be viewed with special anaglyph glasses in 3D. These glasses are equipped with a red and a cyan or blue film before the eyes. The pictures are mostly in black and white, sometimes also colorful. The image for the left eye cyan and the image for the right eye is red, exactly opposite to the color of the glasses. The images are superimposed on one page.

Since each image disappears in front of one eye by the color filter, the result is a three-dimensional image.

 

Andruck

Ein Andruck wird im Gegensatz zum Proof mittels Filmen oder CTP Druckplatten an speziellen Andruckmaschinen mit denselben Farben und Parametern wie der spätere Fortdruck erstellt.

Ein Andruckt ist farblich sehr präzise und auch durch das verwendete Auflagenpapier optisch und haitisch nahezu identisch zum späteren Druck. Im Vergleich zum klassischen Proof aber ist ein Andruck meist um das zigfache teurer und kostet schnell einige hundert Euro. Außerdem benötigt ein Andruck wesentlich mehr Zeit für der Herstellung.  Er ist daher aus wirtschaftlichen Gründen heute kaum mehr relevant und wird nur noch für sehr heikle Drucke mit hohen Auflagen eingesetzt.

Artbox

The Artbox is the smallest box within a PDF file. It covers the area to be used when importing the PDF file into another application. It is comparable to the size specified during the import of an EPS file.
