Abstract
A system enables a rendering intent to be specified for an object in a page description language that does not support the specifying of rendering intents. Such a system includes a user interface for receiving a rendering intent and an identification of an object associated with the received rendering intent, a page description language (PDL) file generator for generating a tag to associate the identified object with a PDL output parameter, and an encoder for encoding the received rendering intent in the PDL output parameter associated with the identified object. Such a system may be used, for example, with a PostScript or a PDF print job file.

A system for specifying rendering intents in a page description language comprising:
- a user interface for receiving a rendering intent and an identification of an object associated with the received rendering intent;
- a page description language (PDL) file generator configured to specify an output color for the identified object with a standard color attribute and to generate an identifier that enables a PDL interpreter to detect a PDL output parameter as a rendering intent parameter and a tag to associate the identified object with the PDL output parameter;
- and
- an encoder configured to generate a code that enables the PDL interpreter to identify the received rendering intent for printing of the object associated by the tag to the PDL output parameter, the identifier that enables detection of the PDL output parameter as a rendering intent parameter and the code that identifies the received rendering intent being stored for the PDL output parameter associated with the identified object to preserve the specification of the output color with the standard color attribute while enabling identification of the PDL output parameter as a rendering intent parameter for the identified object and as enabling identification of the received rendering intent for printing of the identified object with reference to the code stored for the PDL output parameter.
A method for specifying rendering intents in a page description language (PDL) comprising:
- receiving through a user interface a rendering intent and an identification of an object associated with the received rendering intent;
- specifying an output color for the identified object with a standard color attribute;
- generating an identifier that enables a PDL interpreter to detect a PDL output parameter as a rendering intent parameter and a tag to associate the identified object with the page description language (PDL) output parameter;
- and
- encoding the received rendering intent by storing a code that enables the PDL interpreter to identify the received rendering intent for printing the identified object and the identifier for the PDL output parameter associated with the identified object to preserve the specification of the output color with the standard color attribute while enabling identification of the PDL output parameter as the rendering intent parameter for the identified object and enabling identification of the received rendering intent for printing the identified object with reference to the code stored for the PDL output parameter.
A system for specifying rendering intents in a page description language (PDL) comprising:
- a user interface for receiving a rendering intent and an identification of an object associated with the received rendering intent;
- a page description language (PDL) file generator configured to specify an output color for the identified object with a standard color attribute and to generate an identifier that enables a PDL interpreter to detect a PDL overprinted spot color output parameter as a rendering intent parameter and a tag to associate the identified object with the PDL overprinted spot color output parameter;
- and
- a spot color tint generator configured to generate a tint color code that enables the PDL interpreter to identify the received rendering intent for printing of the identified object associated with the PDL overprinted spot color output parameter by the tag, the identifier and the generated tint color code being stored for the PDL overprinted spot color output parameter that is associated with the identified object to preserve the specification of the output color by the standard color attribute while enabling identification of the PDL overprinted spot color output parameter as the rendering intent parameter for the identified object and as enabling identification of the received rendering intent for printing of the identified object with reference to the code stored for the PDL overprinted spot color output parameter.
