CMRs. If there is a match, the printer uses the selected device-specific halftone CMR when it processes the print job. If there is no match, the printer uses the halftone CMR whose line screen frequency value is closest to the one requested. The Color Management Object Content Architecture (CMOCA) has defined a variety of generic halftone CMRs, which cover the most common line screen frequencies and halftone types. A print server that supports CMOCA can interpret generic halftone CMRs if it has device-specific halftone CMRs available to it in a resource library. If you use AFP Resource Installer, the generic halftone CMRs are installed in every resource library that you create and populate by using AFP Resource Installer. Printers that support CMOCA should be able to interpret those generic CMRs and associate them with device-specific halftone CMRs. Tone transfer curve CMRs: Tone transfer curve (TTC) CMRs are used to carry tone transfer curve information for an AFP print job, so you can modify the values of a particular color component and adjust the appearance of some of the colors by increasing or decreasing the amount of ink used to emphasize or reduce the effects of dot gain on the final output. Like halftone CMRs, tone transfer curve CMRs are associated with print jobs specifically or generically. If they are specified generically, the print server looks in the resource library for tone transfer curve CMRs that match the printer device type and model. If the print server finds an appropriate CMR, it sends the device-specific tone transfer curve CMR to the printer with the print job. If the print server does not find an appropriate tone transfer curve CMR, it sends the generic tone transfer curve CMR to the printer. If a print job arrives at the printer requesting a generic tone transfer curve CMR, the printer compares the requested characteristics with the device-specific tone transfer curve CMRs that it has available. If there is a match, the print server or printer uses the selected device-specific tone transfer curve CMR when it processes the print job. If the printer cannot find a good match for the generic tone transfer curve CMR, it ignores the request and uses its default tone transfer curve CMR. The Color Management Object Content Architecture (CMOCA) defines several generic tone transfer curve CMRs with different appearance values. You can use the appearance values to specify how to print your job with regard to the reported dot gain of the printer. Generic tone transfer curves can be used to select these appearance values: v Dark The output is adjusted to show a dot gain of 33% for a 50% dot. v Accutone The output is adjusted to show a dot gain of 22% for a 50% dot. v Highlight Midtone The output is adjusted to show a dot gain of 14% for a 50% dot. This appearance might be used to emphasize the brightest part of an image. v Standard The output is adjusted just enough to account for the effects of dot gain, effectively counteracting the dot gain.

Match case Limit results 1 per page

CMRs. If there is a match, the printer uses the selected device-specific halftone

CMR when it processes the print job. If there is no match, the printer uses the

halftone CMR whose line screen frequency value is closest to the one requested.

The Color Management Object Content Architecture (CMOCA) has defined a

variety of generic halftone CMRs, which cover the most common line screen

frequencies and halftone types. A print server that supports CMOCA can interpret

generic halftone CMRs if it has device-specific halftone CMRs available to it in a

resource library. If you useAFP Resource Installer, the generic halftone CMRs are

installed in every resource library that you create and populate by using AFP

Resource Installer.

Printers that support CMOCA should be able to interpret those generic CMRs and

associate them with device-specific halftone CMRs.

Tone transfer curve CMRs:

Tone transfer curve (TTC) CMRs are used to carry tone transfer curve information

for an AFP print job, so you can modify the values of a particular color component

and adjust the appearance of some of the colors by increasing or decreasing the

amount of ink used to emphasize or reduce the effects of dot gain on the final

output.

Like halftone CMRs, tone transfer curve CMRs are associated with print jobs

specifically or generically. If they are specified generically, the print server looks in

the resource library for tone transfer curve CMRs that match the printer device

type and model. If the print server finds an appropriate CMR, it sends the

device-specific tone transfer curve CMR to the printer with the print job. If the

print server does not find an appropriate tone transfer curve CMR, it sends the

generic tone transfer curve CMR to the printer.

If a print job arrives at the printer requesting a generic tone transfer curve CMR,

the printer compares the requested characteristics with the device-specific tone

transfer curve CMRs that it has available. If there is a match, the print server or

printer uses the selected device-specific tone transfer curve CMR when it processes

the print job. If the printer cannot find a good match for the generic tone transfer

curve CMR, it ignores the request and uses its default tone transfer curve CMR.

The Color Management Object Content Architecture (CMOCA) defines several

generic tone transfer curve CMRs with different appearance values. You can use

the appearance values to specify how to print your job with regard to the reported

dot gain of the printer.

Generic tone transfer curves can be used to select these appearance values:

Dark

The output is adjusted to show a dot gain of 33% for a 50% dot.

Accutone

The output is adjusted to show a dot gain of 22% for a 50% dot.
