10.3 CIE-Based colour to device colour
10.3.1 General
...
Change the last paragraph as follows:
Conversion from a CIE-based source colour to a CIE-based destination colour shall be performed based on ISO 15076-1:2010 (ICC.1:2010)
the appropriate ICC specification (see "Table 66 - ICC profile versions supported by ICCBased colour spaces").
10.6 Halftones
10.6.5 Halftone dictionaries
10.6.5.6 Type 5 halftones
Change Table 132 as follows:
Key | Type | Value |
---|---|---|
Default | dictionary or stream |
(Required) A halftone that shall be used for any colourant or colour component that does not have an entry of its own.
|
...
Delete the paragraph below the bulleted list (above EXAMPLE) as follows:
When a halftone dictionary of some other Type appears as the value of an entry in a Type 5 halftone dictionary, it shall apply only to the single colourant or colour component named by that entry’s key. This is in contrast to such a dictionary’s being used as the current halftone parameter in the graphics state, which shall apply to all colour components. If nonprimary colourants are requested when the current halftone is defined by any means other than a Type 5 halftone dictionary, the gray halftone screen and transfer function shall be used for all such colourants.
10.7 Scan conversion details
10.7.2 Flatness tolerance
Change the first paragraph as follows:
The flatness tolerance controls the maximum permitted distance in device pixels between the mathematically correct path and an approximation constructed from straight line segments, as shown in "Figure 69 — Flatness tolerance". Flatness may be specified as the operand of the i operator (see "Table 56 — Graphics state operators") or as the value of the FL entry in a graphics state parameter dictionary (see "Table 57 — Entries in a graphics state parameter dictionary").
It shall be a positive number.
It shall be a number in the range 0 to 100 inclusive, where a value of 0 shall specify the output device’s default flatness tolerance. The value indicates the maximum error tolerance measured in output device pixels.
