4.4 Exception conditions
In general, no exception conditions are defined within the AFP/A definition for structured fields or their parameters above and beyond what the general MO:DCA architecture defines. The following general rules apply.
Exception conditions should not be generated solely due to non-compliance with AFP/A. When a valid print file is non-compliant with AFP/A, it should always be processed to the best of a receiver’s capabilities. That is, any object, object content, structured field, or structured field triplet that is valid in the general architecture but that is not included in the AFP/A definition, should be processed to the best of a receiver’s capability. For example, a receiver may generate an exception because it detected an error while processing an MCF-1 structured field, but not because the print file claimed to be AFP/A compliant and the MCF-1 structured field is not part of AFP/A.
4.5 Restrictions to avoid device dependence
To ensure that an AFP/A print file can be presented accurately and consistently in the future, functions that are allowed in IS/3 but that are inherently device-dependent are not included in AFP/A. The IS/3 functions that shall not appear in AFP/A print files are the following:
— Device-dependent colours
— Use of the CMYK colour space (ColSpce = X’04’) in Color Specification Triplet and equivalent OCA structures, when not qualified with an audit Color Conversion CMR;
— Use of the Highlight Color Space (ColSpce = X’06’) in Color Specification Triplet and equivalent OCA structures, when not qualified with an Indexed CMR that specifies a substitute CIELab value;
— Device-dependent fonts
— Use of the device default font in PTOCA text (local ID = X’FF’ in SCFL control sequence);
— Use of the device default font in GOCA graphics (local ID = X’OO’ or X’FF’ in GSCS drawing order);
— BCOCA allows the use of a default font to print HRI, and since the HRI is not the actual bar code, AFP/A allows the use of the default font for HRI. However, this may lead to a slightly different appearance when the archived file is re-printed. If it is mandatory that the HRI is reproduced the same way each time the AFP file is printed, the default font should not be used. Instead, a TrueType/OpenType font that is carried in the print file resource group should be referenced and used;
— Images without clearly defined resolution
— AFPC JPEG and GIF images normally do not inherently specify their resolution. This resolution is needed to properly size the object for image presentation space mapping options other than:
the following:
— Scale to fit;
— Scale to fill.
When a mapping option, other than these is specified, these images cannot be included in AFP/A print files unless they specify an Image Resolution (X’9A’) triplet.
— Device-dependent medium map functions — the following MMC keywords:
— X’9Onn’, X’9lnn’: high/low media destination selector;
— X’AOnn’: fixed medium information;AS ISO 18565 pdf download.
