list pattern
Displays a list of the built-in test patterns available.
If the optional integer <n> is specified, a brief description of the specified
pattern is given.
Test pattern 0: Universal
In the univeral pattern, all the patterns are separated by 5 mil clear sections
except for the pieces of the one inch grid. The screens are 16 x 16 cells
yielding a 212 lpi 45 degree screen at 2400 dpi.
The patterns generated by the Universal test pattern include:
5 mils of one inch ticks, 4 mil line, 41 mil of one inch ticks, one inch grid
1,2,4, and 8 pixel vertical on/off.
Patterns from here:
1,2,4, and 8 pixel horizontal on/off on are 45 mils,
1,2,4, and 8 pixel diagonal on/off followed by 5 mil,
3.1% screen (2x2 dot) GAP,
7 % screen (3x3 dot),
12.5% screen (4x4 dot),
20% screen, 30% screen, 40% screen, 50% screen, 60% screen, 70% screen
80% screen, 87.5% screen (negative 4x4 dot), 93% screen (negative 3x3 dot),
96.9% screen (negative 2x2 dot), solid black, 40 mil of one inch ticks
Test pattern 1: Microband1
The Microband1 pattern is made up of 1.495 inch patterns followed by 0.005 inch
gaps. The patterns are as follows:
3 pixel vertical on/off, 3 pixel horizontal on/off, 3 pixel diagonal on/off,
1 x 3 dot in a 4 x 6 cell, 7 % screen (3x3 dot), 12.5% screen (4x4 dot),
30% screen, 50% screen, 70% screen, 87.5% screen (negative 4x4 dot),
93% screen (negative 3x3 dot), 96.9% screen (negative 2x2 dot), solid black
Test pattern 2: Microband2
This pattern is made up of 1.495 inch patterns followed by 0.005 inch gaps.
The patterns are as follows:
2 pixel vertical on/off,
3 pixel vertical on/off, 4 pixel vertical on/off, 5 pixel vertical on/off,
6 pixel vertical on/off, 2 pixel horizontal on/off, 3 pixel horizontal on/off,
4 pixel horizontal on/off, 5 pixel horizontal on/off, 6 pixel horizontal on/off,
2 pixel checkerboard, 4 pixel checkerboard, 8 pixel checkerboard, solid black
Test pattern 3: Exposure blank pattern
Test pattern 4: Exposure screen pattern
Test pattern 5: Blank pattern
Test pattern 6: DPE 1 pixel horizontal bars (DPE testing)
Test pattern 7: DPE 3 pixel horizontal bars (DPE testing)
Test pattern 8: Focus series pattern
Test pattern 9: Microband pattern 3
Test pattern 10: Step wedge
Test pattern 11: Vertical 2 pixel bars
Test pattern 12: Solid pattern
Test pattern 13: DPE 3 pixel vertical bars (DPE testing)
Test pattern 15: 1x1 pixel checker board
Test pattern 16: Microband pattern 4
Test pattern 18: 3-pixel diagonal bars
Test pattern 19: Microband pattern 6, horizontal
Test pattern 20: Blank Gap
Used for testing the Blank Skipping feature (see "carriage skip"). Generates a
solid pattern, followed by a blank pattern, followed by another solid pattern,
then repeats. Each section is variable in width where "temp l1" is the inital
solid width in scanlines (may be zero), "temp l2" is the blank width in
scanlines, and "temp l3" is the final solid width also in scanlines (also may
be zero). Only available on machines equipped with the blank skip feature.
Test pattern 30: 30% screen
Test pattern 50: 50% screen
Test pattern 80: 80% screen
Test pattern 93: 93% screen
Test pattern 97: 97% screen
Test pattern 22: 2x2 pixel checkerboard
Test pattern 33: 3x3 pixel checkerboard
Test pattern 44: 4x4 pixel checkerboard
Test pattern 55: 5x5 pixel checkerboard
Test pattern 66: 6x6 pixel checkerboard
Test pattern 77: 7x7 pixel checkerboard
Test pattern 101: DPE Test 1 - alternating 1's and 0's in sscan/mscan
Test pattern 102: DPE Test 2 - same a DPE Test 1, but different signature
Test pattern 103: DPE Test 3 - walking 1's in mscan
Test pattern 104: DPE Test 4 - walking 0's in mscan
Test pattern 105: DPE Test 5 - walking 1's in sscan
Test pattern 106: DPE Test 6 - walking 0's in sscan
Test pattern 107: DPE Test 7 - 0.2 inch horizontal bars
Test pattern 110: 10 percent screen, 45 degrees
