[Openicc] Linux CM ideology... Print preview

[Ann L McCarthy]

Jan-Peter,

Additional detail for the print preview workflow -- 

Note -- the profile selected for the printer should depend on a number of 
settings, not only the media.

1) Implement the possibility of softproof workflows in the application:
documentICC->softproofICC->DisplayRGB

2)Deliver a solution, where the installed PrinterICC profiles for the 
current CUPS queues are communicated via Oyranos or g-c-m to 
applications (e.g. both CUPS queue name an printer profile name could be 
communicated via Oyranos /g-c-m to the application.

3) Choose (CUPS-queue name / printer profile) for softproof

4) Clarify whether the workflow will use preview tags or the actual B2A 
and A2B tags.

5) Clarify whether the user will have the option to control 'apply 
auto-preference' (which means use the perceptual RI) or 'apply maintain 
colors' (which means use the media-relative RI).

6) Clarify that then the RI sequence should be: for A2B of source 
profile(s) of the document and B2A of the printer profile -- use the 
selected RI of step 5, then use the media-relative colorimetric RI of the 
A2B of the printer profile combined with the media-relative colorimetric 
RI of the B2A of the display RGB profile. In certain cases for more 
advanced use cases it may be important to be able to separately control 
the RI selection for the A2B of the source profile(s) of the document and 
the RI selection for the B2A of the printer profile -- so if this can be 
allowed please do so.  If you would like some examples where this is 
desirable let me know.

Re: [Openicc] Linux CM ideology... Print preview






Hello all,
Here is the workflow for print preview:

Create a workflow, where the rasterized printout from CUPS is duplicated 
and converted from printer-profile whit a user choosen rendering intent 
to displayRGB.

As the printer profile is only defined through choosing the 
media-setting in the printing UI, a print preview is best implemented as 
function of the print UI (and not of an application creating complex PDF 
files)

If there should be a print preview in the application, the workflow 
should be as following:

1) Implement the possibility of softproof workflows in the application:
documentICC->softproofICC->DisplayRGB

2)Deilver a solution, where the installed PrinterICC profiles for the 
current CUPS queues are communicated via Oyranos or g-c-m to 
applications (e.g. both CUPS queue name an printer profile name could be 
communicated via Oyranos /g-c-m to the application.

3) Choose (CUPS-queue name / printer profile) for softproof


Best regards
Jan-Peter
