Abstract
Abstract Page description information received from an interpreter is composed into color plane memories as basic pels for line information and larger, 4 by 2 basic pels for color information, with intensity information for larger color pels also in the color plane memories. A separate color pel memory stores the meaning of the larger pels. Intensity is printed by filling parts of the 4 by 2 color pels as dictated by the intensity information.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
151 words
A method for composing in electronic memory page information in pel form for a page to be printed comprising storing in said electronic memory basic pel information defining binary information received, said storing being in separate regions of said memory for each of at least two hues of subtractive primary colors and for black, storing in said memory in a region for black basic pel information defining binary information received, storing in said memory in separate memory regions for each of at least two said hues of subtractive primary colors intensity information for predetermined groups of basic pels, said intensity information occupying parts of said memory regions otherwise occupied by said basic pel information, and storing in a separate region of said memory information defining the meaning of said groups of basic pels by identifying the previous storing of said intensity information for each of said predetermined groups of basic pels.
Claim 2
Independent Claim
151 words
A method for composing in electronic memory page information in pel form for a page to be printed comprising storing in said electronic memory basic pel information defining binary information received, said storing being in separate regions of said memory for each of at least two hues of subtractive primary colors and for black, storing in said memory in a region for black basic pel information defining binary information received, storing in said memory in separate memory regions for each of at least two said hues of subtractive primary colors intensity information for predetermined groups of basic pels, said intensity information occupying parts of said memory regions otherwise occupied by said basic pel information, and storing in a separate region of said memory information defining the meaning of said groups of basic pels by identifying the previous storing of said intensity information for each of said predetermined groups of basic pels.
Claim 3
Dependent Claim
28 words
The method as in claim 1 in which said hues are cyan, magenta, and yellow and said group of pels comprises at least six of said basic pels.
Claim 4
Dependent Claim
20 words
The method as in claim 2 in which said group of pels comprises eight of said pels in a rectangle.
Claim 5
Dependent Claim
40 words
The method as in claim 3 in which said groups of basic pels are predetermined and said intensity information is entered in each said group when color and intensity information is received for any basic pel in each said group.
Claim 6
Dependent Claim
40 words
The method as in claim 1 in which said groups of basic pels are predetermined and said intensity information is entered in each said group when color and intensity information is received for any basic pel in each said group.
Claim 7
Dependent Claim
40 words
The method as in claim 2 in which said groups of basic pels are predetermined and said intensity information is entered in each said group when color and intensity information is received for any basic pel in each said group.
Claim 8
Independent Claim
110 words
A method for composing in electronic memory page information in pel form for a page to be printed comprising storing in said electronic memory basic pel information defining binary information received, said storing being in separate regions of said memory for each of at least two primary colors and for black, storing in said separate memory regions for color intensity information for predetermined groups of basic pels, said intensity information occupying parts of said memory regions otherwise occupied by said basic pel information, and storing in a separate region of said memory information defining the previous storing of said intensity information for each of said predetermined groups of basic pels.
Claim 9
Independent Claim
110 words
A method for composing in electronic memory page information in pel form for a page to be printed comprising storing in said electronic memory basic pel information defining binary information received, said storing being in separate regions of said memory for each of at least two primary colors and for black, storing in said separate memory regions for color intensity information for predetermined groups of basic pels, said intensity information occupying parts of said memory regions otherwise occupied by said basic pel information, and storing in a separate region of said memory information defining the previous storing of said intensity information for each of said predetermined groups of basic pels.
Claim 10
Dependent Claim
29 words
The method as in claim 7 in which said primary colors are cyan, magenta, and yellow and said group of pels comprises at least six of said basic pels.
Claim 11
Dependent Claim
20 words
The method as in claim 8 in which said group of pels comprises eight of said pels in a rectangle.
Claim 12
Dependent Claim
41 words
The method as in claim 9 in which said contiguous groups of basic pels are predetermined and said intensity information is entered in each said group when color and intensity information is received for any basic pel in each said group.
Claim 13
Dependent Claim
41 words
The method as in claim 9 in which said contiguous groups of basic pels are predetermined and said intensity information is entered in each said group when color and intensity information is received for any basic pel in each said group.
Claim 14
Dependent Claim
41 words
The method as in claim 8 in which said contiguous groups of basic pels are predetermined and said intensity information is entered in each said group when color and intensity information is received for any basic pel in each said group.
Claim 15
Independent Claim
135 words
A method of printing color and line information on the same page comprising storing in electronic memory in a pel plane basic pel information for said line information, storing in electronic memory for each of at least two subtractive primary colors in a pel plane for each said primary color, color intensity information for said color information applicable to contiguous groups of basic pels, said pel plane for each color and for black being separate, storing in electronic memory separate from said pel planes information identifying the previous storing of said intensity information for said contiguous groups, and printing said basic pel information at pel locations in one predetermined intensity, and printing said color information in a part of said contiguous groups in an amount defined by said intensity information of each said continuous groups.
Claim 16
Independent Claim
135 words
A method of printing color and line information on the same page comprising storing in electronic memory in a pel plane basic pel information for said line information, storing in electronic memory for each of at least two subtractive primary colors in a pel plane for each said primary color, color intensity information for said color information applicable to contiguous groups of basic pels, said pel plane for each color and for black being separate, storing in electronic memory separate from said pel planes information identifying the previous storing of said intensity information for said contiguous groups, and printing said basic pel information at pel locations in one predetermined intensity, and printing said color information in a part of said contiguous groups in an amount defined by said intensity information of each said continuous groups.
