Abstract

Abstract A method of using a printer system (Fig.1) for identifying one or more different types (41-43) of color objects in a document, selecting a preferred rendering option such as halftoning and/or color matching for each one of such different color object types (41-43), respectively, and then printing the document in accordance with the rendering options selected for each of such different color object types (42-43). In a printing system such as an inkjet color printer (56) coupled through a printer driver (32) to a host computer (44), a default halftoning technique and a default color-matching map are incorporated into the printer system for automatic invocation whenever a particular color object type (41-43) is printed. <IMAGE>

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 56 words
A method of printing a composite document including at least one object of one of a plurality of object types (41-43), including the steps of identifying the type of the or each object of the document; and using a predetermined first rendering option to print the or each object of a first identified object type (41).
Claim 2
Dependent Claim 33 words
A method according to claim 1, comprising the step of employing a predetermined second rendering option to print objects of one or more object types (41,43) different from said first object type (41).
Claim 3
Dependent Claim 23 words
A method according to claim 1 or 2, comprising the step of employing a specific print rendering option for each identified object type.
Claim 4
Dependent Claim 26 words
A method according to claim 1, 2 or 3, wherein a half-tone colour rendering option is used for objects identified as being of a photographic type.
Claim 5
Dependent Claim 27 words
A method according to claim 1, 2 or 3, wherein a colour matching colour rendering option is used for objects identified as being of a photographic type.
Claim 6
Independent Claim 47 words
A method according to any preceding claim, wherein all raster data commands are identified as being of a photographic type, all text objects are identified as being of a text type and/or all objects which are not text commands are identified as being of a graphics type.
Claim 7
Dependent Claim 58 words
A printing system for printing colour documents in a raster printer comprising a print (56) for applying printing material to media; a document source (60-99) for providing specifications of a composite colour document including non-text colour objects (41,42) and colour management means (44,45) for providing print rendering options which can be selectively enabled for said non-text colour objects.
Claim 8
Dependent Claim 29 words
A printing system according to claim 7, wherein said colour management means (44,45) is operative automatically to provide default settings for at least one of said print rendering options.
Claim 9
Dependent Claim 32 words
A printing system according to claim 7 or 8, wherein said colour management means (44,45) is operative to provide half-tone print rendering options which can be enabled for said non-text colour objects.
Claim 10
Dependent Claim 43 words
A printing system according to claim 7, 8 or 9, wherein said colour management means (44,45) is operative to provide half-tone print rendering options and/or colour matching print rendering options which can be separately enabled for two different types of non-text colour objects.
